Gold Allergy

An allergy is a hypersensitivity to a substance that causes the body to react to any contact with that substance. 
Do I have an allergy to gold?
Probably not, that is not gold itself. What people occasionally have is an allergy to the nickel content in gold alloys, usually in the alloy rich 9ct golds. 9ct alloys go dull or even black from the exposure to chemicals in the atmosphere and also may discolour from contact with perspiration, bleach, household chemicals and some fabrics.


Allergy Test KitDetergents and other chemicals lodge between rings and the skin causing problems, particularly hairspray, beauty and cleaning products. Antiperspirants exacerbate metal allergy problems. It has been suggested that the sweat of a healthy person after exercise contains 18 times the nickel content of blood. The antiperspirant reduces the bodies natural way of eliminating heavy metals and can lead to a build up in intensity, which causes a higher concentration in the sweat than is normal.

The most common type of allergy we encounter is a phantom allergy, caused by a noticeable desire to upgrade to 18ct or platinum!. As nickel and zinc are not used in 18ct alloy, just silver and copper, it is less likely to produce any kind of allergy related problems. What a good excuse! 

Tarnishing of Gold
Possible causes include:
  • Perspiration (everyone's body chemistry is different, hence this is why some are more susceptible than others); for women, the time of the month can influence their body chemistry. 
  • Perfume, hair or deodorant sprays, 
  • Tarnishing during storage (storage boxes may contain organic sulphur compounds),
  • Leaching of acid/ cleaning solutions from surface microporosity from cast jewellery; this causes corrosion locally (such porosity may even trap perspiration during wear, causing local corrosion) 
  • Preparation of vegetables such as onions and spices (many foodstuffs contain sulphur compounds and others are also acidic).
Another possible mechanism may be surface micro-porosity on the surface of investment (lost wax) cast items. This porosity may trap acids and other cleaning solutions, sprays, or perspiration and cause a local corrosion which 'creeps' over the surface of the item. 

The tarnish films formed are generally harmless although unsightly and may lead to a black smudging of the skin. Such films can be easily polished off by a jeweller to restore the bright gold colour. 

Possible solutions to the problem include: 

  • Store jewellery in a pouch or bag in a dry atmosphere (unpolluted, e.g. by exhaust fumes, solvent vapours, where possible).
  • If stored in a box or pouch or plastic bag, ensure it is free of sulphur-containing compounds (from solvents, fabric treatments, adhesives, etc.).
  • Polish jewellery regularly with a soft cloth to remove any early tarnish films, perspiration and other contaminants (sprays, etc). Clean after wear and do not put on perfume, deodorants, sprays, etc whilst wearing the jewellery

Alternative white gold alloys

In the European Union especially, there is a demand for cheaper alternatives to white golds than the palladium whites which are 'nickel-free'. Many new alloys are coming to market, most of which rely on manganese additions as the main whitener. Some are palladium-free and others are low palladium alloys. Chromium and iron are also be used as whiteners. They tend to be hard and more difficult to process. Many of these alloys are not a good white colour, requiring rhodium plating, and many suffer cracking problems and tarnishing.
We recently tried to anneal a batch of white gold from Italy. It was so unmalliable we had to contact the manufacturer, and whilst the solution was simple, a high street working jeweller would find the new metals difficult, if not impossible to process.

Platinum, chromium, cobalt, zinc, tin and silver are all used as whiteners. Silver has excellent working properties but is poor as a whitener. Copper is also added to improve the ductility of most white alloys.

Rhodium Plating
It is important to remember that even the best white gold alloy is actually grey, as is platinum. The white finish you are accustomed to is a rhodium plating, and whatever you are told, white golds are only available in caratages up to 21 carat. It is not possible to have a 22 ct white gold!


Resistance to Tarnish 

18 carat and 22 carat gold alloys are almost completely resistant to chemical attack and 9ct alloys are much less resistant. Nine carat alloys can dull or even blacken from exposure to chemicals in the atmosphere, and might discolour in contact with household chemicals. 9ct chain is usually finished with a deeper yellow 18ct or 22ct coating by manufacturers, which is why the bright finish on a new 9ct chain gradually tones down to match other jewellery that you wear on a daily basis.
The original bright finish can usually be restored quite inexpensively by a working jeweller for little cost should your chain become chemically or mechanically damaged over the years.

Hardness 
As well as affecting physical properties, alloying gold generally increases the strength and hardness, with some reduction in malleability / ductility. The silver atom is slightly larger than that of gold, so alloying gold with silver gives a moderate improvement in strength and hardness. The copper atom is significantly smaller than that of gold and so it has a greater effect on strengthening gold than silver, as it distorts the gold crystal lattice more. Thus reducing caratage from 24 carats through 22 ct down to 18 carat gold results in stronger and harder alloys, but alloying beyond 18 ct down to 9 carat does not have much further effect.

Palladium white golds

Palladium is the next choice for use in white gold alloys and, apart from its high price and high melting point (1552 degrees celsius), is an ideal alloy. 
Small Commercial Rhodium Plating Tank
Additions of about 10 -12% palladium to gold impart a good white colour. But palladium is an expensive metal and it is also a heavy metal. Thus jewellery in such palladium white golds will be more expensive than identical pieces in nickel whites for 2 reasons: firstly, the cost of the palladium and secondly, the impact of density - palladium white golds are denser and so such jewellery will be heavier. It is also more difficult to process as the melting temperatures are substantially higher.
Many commercial palladium white golds only contain about 6-8% palladium plus silver, zinc and copper. Some may even contain some nickel [so a palladium white gold is not necessarily nickel-free]. These may also have less than a good white colour and so may also be rhodium plated.
Palladium white golds tend to be softer and more ductile compared to nickel whites and so generally will not wear as well. However, despite its higher base cost and workshop recovery costs, making a more expensive product, the advantages of a non nickel alloy now out weigh these factors. 

White Gold

All our white gold jewellery is compliant with Nickel free directives, with less than 0.05% nickel content, with release rates less than 0.5 micrograms per square centimetre per week, as determed in EN1811:1998 and EN1810:1998. We use an expensive silver-rich alloy to produce the white colour which is best described as a warm white. This whiteness is then enhanced with a rhodium plating and whilst this will fade in time, it can easily be reapplied to restore the original finish by a working jeweller.

Gold is yellow, copper is reddish, and all other metals are a silvery grey in colour. 
Refining an Ingot of GoldThere are however gold alloys, that is mixes of differing metals, that appear grey/white.
White gold (alloy) became popular around 1920 as a substitute for platinum, as platinum was quite expensive. Simply mixing a white and yellow metal together will not produce a colour in the same way that mixing paint does. The most common metal used to 'bleach' gold is nickel which is both inexpensive and provides a good platinum look-alike in 18ct alloys.
It has however been linked to dermatitis through allergic reactions with the skin. It has also been suggested that it may be slightly carcinogenic. A recent E.U directive has indicated that soon all jewellry will have to be nickel safe with only a few ppm being allowable.

Gold Alloys

For most uses of gold the pure metal is too soft on its 18ct Yellow Alloy Casting Grainown and is therefore hardened by the Heating Crucibles for small Castaddition of alloying elements, copper, silver, nickel, palladium and zinc. Gold is of course yellow and the various colours seen such as red, white and green are simply alloys of gold. The final colour is dependent on the ratios and type of alloys added.

How To Gain idea of the Price of The Gold?

Weights of products we send you may vary from those shown on this website due to manufacturing tolerances. Prices charged on your invoice will be based on the actual weight of the products delivered to you. In the gold section the final price you pay will be based upon the gold price at the point at which you order, and the exact weight of the items you have selected. The weights quoted are estimated weights.
For example: if you select a curb bracelet at £7.05 per gram at a weight of 6.5 gms the cost will be:

7.05 x 6.5 = £45.83 which we calculate for you. 
When your bracelet arrives it may weight 6.3 gms so you will be charged:
7.05 x 6.3 = £44.42 
or it may weigh 6.7 gms and you would be charged: 
7.05 x 6.7 = £47.24 
but the gram price of 7.05 will be the same - same good value, whatever the weight.
This is the way that almost the entire wholesale jewellery trade operate, and the only way to operate effectively if you work on small margins. When a shop purchases gold from a wholesale jewellers, the goods are weighed and a price per gram paid, the same way that we charge you. UK gold prices are fixed twice a day and we often change prices to reflect this, so an item in which you were interested in the morning may be a different price in the afternoon.
Prices quoted are what you pay, there is NO additional Vat to calculate.
Price Per Gram (ppg)
This is a calculation that allows jewellery dealers to compare how much we are paying for an item. If we wished to purchase a curb chain for instance that costs £100 and weighs 25 grams the cost per gram is:

100 divided by 25 = 4 pounds per gram. 

We are paying £4 for every gram of gold. If another chain costs £200 and weighs 40 gms, the cost per gram is 

200 divided by 40 = 5 pounds per gram. 

We are paying £5 for every gram of gold. 
The second chain is more expensive on a per gram price, and to be an equal bargain should cost £160 ( 40gms x 4 pounds per gram). We calculate this for you so you can compare our prices. If a shop will not tell you how much a chain weighs, or is unable to calculate this for you, there is usually a reason!. To calculate the price per gram then:
1: Find 2 similar products 
2: Take the cost price 
3: Divide this by the weight

The one with the lowest number is the better deal for identical products. ie 4 ppg is better value than 5 ppg.  

Gold Weight

Troy Ounce 

One Troy ounce of gold weighs 31.1035 grams. 
One ounce of gold is accepted to mean 31.1 grams of pure 24 carat gold although in reality it is likely to be 0.9999% pure, often called four nines. 
Imperial ounces, equivalent to 28 grams, are not used. 

Gold Content

A carat is both a unit of weight and also an indication of fineness, that is, a value for the percentage of pure gold content. 24 carat gold represents 100% gold with no alloy content. 
Example:
A one ounce, 1 (Troy) ounce, 9ct gold bracelet weighs 31.1gms.
Actual gold content is (9/24)*31.1=11.66gms of pure (24ct) gold. This also means that (31.10-11.66) 19.44 gms in every troy ounce are other alloys. These alloys, like silver and copper, give rise to the qualities of the metal such as colour and hardness. 


Metal:Parts Per ThousandGold Content/Troy oz

14ct gold58518.14 gms
18ct gold75023.33 gms

Ladies -07 bracelets are 7.5 inches standard and Gentlemans -08 are 8.5 inches standard length.
Some of our very heavy Gentlemans bracelets are as long as 9.5 inches (24cm) to accomodate a larger wrist.
Ankle bracelets are usually 9 inches.
Ladies short neck chains ideal for diamond pendants are around 16 inches, 18 inches is a usual length, and a longer 20 inches is good for most gentlemen.
Chains greater than 20 inches in length are considered to be long.

Your questions about platinum jewelry

Why is platinum's purity important to me? Platinum is hypoallergenic, resists tarnish, is one of the strongest precious metals in the world and is extremely durable.
Is platinum the same as white gold? No, it is quite different. During World War II, the U.S. government prohibited platinum's use in all non-military applications, including jewelry. Because of strong consumer preference for platinum's pure white luster, white gold was substituted in platinum's absence. To create white gold, yellow gold is alloyed with nickel and zinc (and small amounts of copper and silver), thereby achieving a white metal look. Platinum has purity, strength, rarity, durability, and a natural rich, white color.
How should I care for and clean my platinum jewelry? Platinum jewelry should be cleaned the same way you clean other fine jewelry. Use a good pre-packaged jewelry cleaner available from your local jeweler or have it professionally cleaned by your jeweler. As with all precious jewelry, store with care, not allowing pieces to touch or scratch each other.
Will platinum scratch? Signs of wear, including scratches, will inevitably appear in all precious metals, even with platinum. Due to platinum's amazing durability and strength, however, there is little or no material loss when it is scratched.
Is platinum fashionable? How will it coordinate with my gold jewelry? Yes, platinum is fashionable! It is very fashionable to wear platinum jewelry with your other fine gold jewelry. Platinum jewelry often contains karat gold design accents, just as karat gold jewelry is sometimes accented with platinum. Platinum's white color beautifully contrasts with yellow gold and adds versatility to your existing jewelry wardrobe.
Is platinum a good value? Yes! Platinum is an excellent value because of its inherent qualities: its purity, its strength, its durability and its rarity. When you purchase platinum jewelry, you are buying jewelry that is almost 100% pure. In the U.S., platinum jewelry is generally 90% or 95% pure platinum, with 5% or 10% alloy of a platinum group metal. By comparison,18 karat gold is 75% pure gold and 14 karat gold is 58% pure gold.
No other precious metal is as pure or bears all the qualities of platinum. Worn over a lifetime and passed on to future generations, platinum is the jewelry metal of choice.

Buying platinum jewelry

Whether you are choosing a ring, pin, bracelet, necklace or bridal jewelry, new and sophisticated designs have created a wide range of platinum jewelry. Many current platinum designs feature 18-karat gold accents. This combination of metals enhances the unique qualities of each.
In the U.S., platinum jewelry usually contains 90% or 95% pure platinum. If a piece of platinum jewelry is marked "iridplat," then it generally contains 90% platinum and 10% iridium, a platinum group metal. If it is marked "plat," then it is at least 95% platinum and another platinum group metal, most likely ruthenium.
Owning a piece of platinum jewelry is a distinct pleasure. You can feel and see the difference; platinum is heavier and denser than other metals and it has an elegant, rich white luster. Buying platinum jewelry is a wise investment. Platinum is one of the rarest, purest and most enduring metals available.
An experienced jeweler can assist you in selecting platinum jewelry that will bring pleasure to you and the recipient for years to come.

Platinum & weddings... the perfect marriage

As platinum's pure white luster, strength and durability are recognized and admired. Bridal couples worldwide are rediscovering platinum as the metal of choice for bridal jewelry.
A diamond and its setting should be forever. Because platinum is superior to other metals in strength and durability, it offers a diamond greater protection. The breathtaking radiance of a diamond fused with the timeless elegance of platinum creates a rare and enduring symbol of lifelong love.

Platinum jewelry

Many jewelry designers and manufacturers feel that platinum is best suited for both diamond and colored stone jewelry because of its strength and durability. Platinum prongs show little wear, and thus offer precious stones greater protection.
Platinum is also one of the most enduring jewelry metals. That's why the world's most famous diamonds, like the Hope, Jonker Diamond Number One, and the Koh-i-Noor, are all secured by platinum settings. Faberg, the famed nineteenth century Russian jeweler, prized platinum, as did Louis Cartier of Paris and many of the great jewelers throughout history.
Choosing a stone is only part of the jewelry-buying process. The setting is just as important, and platinum jewelry offers unusual strength and durability. Fine platinum jewelry endures. Classic design outlives the whims of fashion and retains its character forever.

Why platinum?

Platinum is among the finest, purest and rarest precious metals on earth, and has an understated elegance that appeals to both men and women.
Platinum is strong. Platinum, one of the strongest and most enduring metals in the world, is also one of the heaviest: it weighs 60% more than karat gold. It is ideal for jewelry worn every day because it exhibits little material loss, even after prolonged wear.
Platinum is pure. In the U.S., platinum jewelry generally contains 90% or 95% pure platinum. By comparison, 18 karat gold is 75% pure gold and 14 karat gold is 58% pure gold. Platinum is hypoallergenic and resists tarnish.
Platinum is rare. To produce a single ounce of platinum, a total of 10 tons of ore must be mined. In comparison, only three tons of ore are required to produce one ounce of gold. Rarity lends platinum its cachet.
Platinum is lustrous. Platinum's rich white luster perfectly complements diamonds and other precious gems. Its neutral color enhances a stone's brilliance and depth.
Platinum is fashionable. Platinum jewelry appeals to many people today because of its subtle beauty and elegant understatement. Many platinum jewelry designs are accented with 18 karat gold, creating a sophisticated, versatile and fashionable look.

The world's most precious metal

For its beauty and value, platinum has always been the ultimate expression of celebrations of all kinds: from weddings and anniversaries, to birthdays, holidays and other special occasions.
One of the rarest precious metals on earth, platinum is found in only a few locations in the world.
Platinum has a rich and noble history. It was first used by the ancient Egyptians about three thousand years ago. Eight hundred years later, the South American Incas worked with platinum. The first platinum jewelry in Europe appeared around the year 1780, at the court of Louis XVI of France.
It may surprise you that, although platinum has been around for centuries, it has only been used to fashion jewelry for less than two centuries. It is both an ancient and a young metal.
