About Platinum Jewelry: Platinum stands apart from other precious metals due to its defining qualities of purity and durability. 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. Platinum is durable and more dense than yellow gold. Platinum jewelry lasts for ages and can be passed down from generation to generation. 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 is also a symbol of status and reputation. It looks subtle and not as obvious as yellow gold. Gemstones set in platinum are not distracted because of the metal’s neutral appearance. The color, brilliance and vibrancy of diamonds and colored stones are amplified next to platinum “true white”.
