Precious Metals


Rare, valuable and durable, platinum is the purest of all metals used for fine jewelry. The beautiful cool white luster shows little wear, making it an ideal setting for gemstones. Because it is considered more valuable than gold - it's 35 times rarer - a stone set in platinum will cost more than the same stone set in gold. In the United States, jewelry stamped with "PLAT" must be at least 90% pure platinum to earn the mark. 14k or 18K YG: Gold (Yellow): Diamonds, Engagement Rings and Fine Jewelry at American Diamonds Forever
