Platinum rings

Platinum is a dense, stable and rare metal that is often used in jewellery because of its attractive silver-like appearance. Platinum is a highly valued and desired metal with a wide range of uses, including jewelry, catalytic converters, electrical contacts, pacemakers, drugs and magnets.

Platinum is a silver-white metal — it was once known as "white gold." It is extremely resistant to tarnishing and corrosion (which makes it known as a "noble metal") and is very soft and malleable, making it easy to shape; ductile, making it easy to stretch into wire; and unreactive, which means it doesn't oxidize and is unaffected by common acids.

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.

In 1820, Colombia was the only known source of platinum. As production began to decline, deposits were by chance discovered in the Ural mountains of Russia. These became the principal source of platinum for the next 100 years.

In Canada in 1888, platinum was discovered in the nickel-copper ores of Ontario. Between the end of the First World War and the 1950s, Canada was the world's major source of supply. In 1924 a farmer in the Transvaal province of South Africa discovered several nuggets of platinum in a riverbed. Following this up, the geologist Hans Merensky discovered two deposits each of around 100 kilometers in length. These became known as the Bushveld Igneous Complex and its mines today provide three quarters of the world's platinum output.

During the 1960s, demand for platinum in jewellery experienced a spectacular rise in Japan, appealing to the Japanese public by virtue of its purity, color, prestige and value. Platinum jewellery later succeeded in penetrating other markets - in Germany in the 1970s, Switzerland and Italy in the 1980s and the United Kingdom, the USA and China - today the world's biggest single market for platinum jewellery - in the 1990s.

More than 2,000 years ago the Indian civilizations of South America made rings and ornaments from platinum nuggets found in riverbeds. An even earlier example of platinum as a decorative material is found on an Egyptian casket from the 7th century BC.

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.

Platinum is one of the strongest and most enduring metals in the world. It can be repeatedly heated and cooled without hardening and oxidation effects, while even the most slender sections of platinum permanently retain their shape, providing a secure setting for diamonds and giving jewellery designers a freedom of invention not always possible with other materials.

Platinum 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 does make certain demands on the jeweler’s skills. It requires high temperature melting and casting equipment (pure platinum melts at 1769oC) and a scrupulously clean working environment. Careful attention to polishing technique is needed to achieve the highly reflective finish which shows a diamond or other precious stone at its best.

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.

Many times platinum is disguised with white gold. As much as white gold may look alike as platinum, white gold fades off to a yellowish tinge whereas platinum rings remain white because platinum is naturally white.

White gold rings are composed of gold, alloys, and a rhodium plating which gives it a white look that’s very similar to platinum. 14k white gold and 14k yellow gold have the same gold content and purity (58.5% gold), but the alloys in white gold (and the rhodium plating) make it appear white, while the alloys in yellow gold do not. While white gold looks very similar to platinum, over time the rhodium plating in white gold will wear off and fade to a yellowish tinge. Once you re-polish and re-plate the white gold ring, it will look white again. Platinum, which is naturally white, will not fade to yellow.

Furthermore, platinum rings and gold rings differ in cost. Gold and platinum are similar in price per gram, platinum is more dense and so more of it is required to make a ring. Additionally, platinum rings are usually 95% pure platinum, while 14k gold is only 58.5% gold (18k gold is 75% gold). This means platinum rings are more expensive.

Despite being stronger and more durable, platinum is a softer metal than 14k gold. This means it will get scratched a little easier than 14k gold would.

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's rich, white luster perfectly complements diamonds and other precious gems. Its neutral color enhances a stone's brilliance and depth.

One more benefit of platinum is that it is hypoallergenic. While gold rings do not create an allergy issue for most people, some can develop an allergic reaction from the nickel alloy used in the gold rings.

Platinum rings 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.

Platinum is among the finest, purest and rarest precious metals on earth, and has an understated elegance that appeals to both men and women.
