If all the platinum ever mined were melted down, it would only fill an average-sized living room to about ankle height. This rarity makes platinum more valuable than more common metals like gold or silver. Platinum is dense and durable. It is highly resistant to corrosion and tarnish, making it an excellent choice for jewelry that needs to withstand everyday wear and tear. Its strength and durability mean that platinum jewelry is less likely to get scratched or damaged compared to other metals, maintaining its beauty over time. Platinum jewelry lasts for ages and can be passed down from generation to generation. Purity and durability — those two characteristics define platinum from the rest of the precious metals. From the chemical perspective, platinum is one of the most stable elements. The white color of platinum comes from its purity. While white gold contains an alloy of zinc, copper and nickel, platinum has a pure 95-98% composition. In fact, white gold is yellow gold mixed with other metals and then rhodium plated. Because of its purity, platinum also is hypoallergenic. Those who are allergic to certain metals, such as nickel, often find platinum to be a safe and comfortable choice for jewelry. Platinum’s purity and strength make it relevant to the idea of eternal love. It’s an embodiment of strong feelings and rarity. That’s why platinum engagement rings and platinum wedding bands have been popular ever since. Platinum has always been a symbol of status and reputation. It looks subtle and not as noticeable as yellow gold. Gemstones set in platinum look well pronounced due to the metal’s neutral appearance. The color, brilliance, and vibrancy of diamonds and colored stones are amplified next to platinum “true white”. About Art Deco Jewelry: Art Deco jewelry has remained highly appreciated since its appearance in 1920s — the time also knows as Jazz Age. The style continuously remains popular until today with several Art Deco Revival waves throughout the century. What’s the secret of Art Deco success? - First comes the design itself. Neat geometrical shapes embodied in platinum makes a refined jewelry piece look very appealing. Simple yet powerful, straight lines along with precise workmanship create a striking impression. Add to that a pear or marquise cut gemstone and you won’t be able to forget that perfect Art Deco piece. Platinum, being the most popular material during Art Deco era, also contributed to the period jewelry popularity. At that time the Merensky-Riff, the world’s largest platinum deposit, was discovered in South Africa. And platinum’s title as the main Art Deco metal was fully established.
