Other metals in jewelry


Palladium has been used as a precious metal since 1939.

Discovered in 1803 by William Hyde Wollaston, Palladium is named after the asteroid Pallas.

In 2012, Russia was the top producer of palladium followed by South Africa, they account for 80% of palladium production.

Jewelry consumes 5% of the palladium demand.

Palladium is one of the three most popular metals used to make white gold alloys

It is an ideal substitute for white gold. Palladium is particularly popular as a metal for wedding rings.

Palladium like gold it is also ductile, which means that palladium can also be beaten into leaf form.

As with all precious metals, palladium jewelry will carry a hallmark declaring its quality and authenticity. Articles can be marked as containing a minimum of 500, 950 or 999 parts per thousand of palladium.

Rhodium is a hard, silvery, durable metal that has a high reflectance.

It was discovered in 1803 by William Hyde Wollaston.

It is found in platinum or nickel ores

It is one of the rarest and most valuable precious metals.

It is resistant to corrosion and does not oxidize

White gold is often electroplated with a thin layer of rhodium to give it a shiny silvery white color. Sterling silver can be plated with rhodium for tarnish resistance.

Rhodium is found in platinum ores in South Africa and North America.

The main exporter of rhodium is South Africa followed by Russia. The annual world production of this element is 30 tonnes

Solid rhodium jewelry is very rare, because the metal has both high melting point and poor malleability making such jewelry very hard to fabricate.

Titanium is a fashionable, stylish and durable metal.

Titanium was discovered in 1791 by William Gregory

In 1946 Kroll showed that pure titanium could be produced commercially and since then titanium use has grown, becoming particularly fashionable in jewelry and watch making in recent years.

The metal is extracted from its principal mineral ores via the Kroll process. A more recently developed method, theFCC Cambrige process, may eventually replace the Kroll process

The element occurs within a number of mineral deposits, principally rutile and ilmenite.The two most useful properties of titanium are corrosion resistance and the highest strength-to-density ratio of any metallic element.

Because of its durability, titanium has become more popular for designer jewelry, particularly,titanium rings. Its inertness makes it a good choice for those with allergies or those who will be wearing the jewelry in environments such as swimming pools or ocean.

Titanium is a lustrous white metal with a low density, great strength and resistance to erosion. As strong as steel but 45% lighter it is also twice as strong as aluminum but 60% heavier.

Titanium is the most hypoallergenic metal available.

Being hypoallergenic it is perfect for earrings. And because it is lightweight it makes a great bracelet for a man or women.

Titanium is naturally a silver white color similar to platinum. It is also available in a black color. The black color is not plating.

Tungsten,also known as wolfram, is a steel grey metal that is currently very popular in wedding rings.

It was identified as a new element in 1781, and first isolated as a metal in 1783.

It has the highest melting point of all the elements.

Its density, similar to that of gold, allows tungsten to be used in jewelry as an alternative to gold or platinum. Metallic tungsten is harder than gold alloys, and is hypoallergenic.

Tungsten rings are also set with wood, other metals or gemstones and are the height of modern style and sophistication for any man getting married.

Gold plated tungsten is available commercially from China both in jewelry and as bars.

Tungsten Carbide jewelry is very popular right now, especially in men’s jewelry.   Regardless of activity tungsten carbide will not scratch.

Pewter includes any of the numerous silver-gray alloys of tin with various amounts of antimony and copper.

Pewter is one of the oldest known metal alloys and may have been used as early as 1500 BC.

Pewter is a malleable metal alloy, traditionally 85–99% tin, with the remainder consisting of copper,antimony,bismuth and sometimes, less commonly today,lead.

For usefulness in jewelry it is composed of 96-99% of tin and 1-4% of copper.

Pewter is the fourth most popular metal used in jewelry, behind gold, silver, and platinum. Pewter is popular because it can be polished to a high shine. Because of its low melting point, those who work with pewter are able to create jewelry with intricate detail.

Is a family of alloys with a base metal of zinc and alloying elements of aluminum, magnesium, and copper. The specifications in the chemistry of zinc were set around 1935.

The first company to develop Zamak was the New Jersey Zinc Company, who created it in 1929

The most common zamak alloy is zamak 3. Composition for the zamak 3 alloy is 96% zinc, 4% aluminum. Zamak 5 has the same composition as zamak 3 with the addition of 1% copper. Zamak 5 is more commonly used in Europe.

Zamak can be electroplated.

Lately its use has been spreading in fashion jewelry because it is a cheap material that allows getting good esthetic results with a low cost.

The problem of zamak is its poor durability. A loss of brilliance is observed and a humidity presence causes corrosion.

The application and the production of zamak has not changed much over the past 80 years.

Zamak is depicted using a series of codes that indicate exactly how it is made.

Brass is an alloy made of copper and zinc; the proportions of the copper and zinc are varied to yield many different kinds of brass. Basic modern brass is 67% copper and 33% zinc.

Lead commonly is added to brass at a concentration of around 2-5%. The lead addition improves the machinability of brass. Eco Brass is a lead free alternative that uses silicon instead of lead.

Brass is fast becoming one of the most popular materials in jewelry.

Brass is a cheaper option than gold or silver.

Brass is widely used in necklaces or bracelets. But you will also find it is increasingly used in contemporary designs.

Brass has higher malleability than bronze or zinc.

Bronze is an alloyconsisting primarily of copper, usually with tin as the main additive

There are many different bronze alloys, but typically modern bronze is 88% copper and 12% tin.

Bronze has a tendency to oxidation.

Many bronze mixes have nickel in them. Nickel allergies are very common and affect six in every 100 people, according to reports from New York University’s Department of Dermatology.

Bronze jewelry often contains copper, which will turn your skin green whether you have an allergy or not. Bronze and copper turn your skin green because when the copper reacts with your sweat and the acids from your skin, it produces copper chloride. Copper chloride is a green substance that then rubs off on your skin.

Tombac is an alloy formed from copper (84 – 90%) and zinc (10 – 16%), resembling brass.

Called also German brass or Dutch brass

The addition of arsenic produces White Tombac.
