Black gold is a real, human-made gold alloy that doesn’t occur naturally. It’s created through electroplating yellow gold with black rhodium or ruthenium, alloying gold with metals like cobalt (75% gold, 25% cobalt), laser treatment and purposeful oxidation processes. Black gold is generally hypoallergenic and non-magnetic, except when alloyed with cobalt, which creates magnetic properties … Read more

Argentium silver is a modern silver alloy created in 1990 by Peter Johns, a professor of silversmithing at Middlesex University in England. It contains 93.5-96% pure silver plus germanium, making it more valuable and superior to traditional sterling silver’s 92.5% purity. The name comes from the Latin word “argentum” meaning silver. Germanium acts as an … Read more

Platinum 850 is a platinum alloy containing 85% pure platinum and 15% other metals like palladium or copper. Platinum 850 is less pure than platinum 950 or 900, but it’s still a high-quality, more affordable option for jewelry making. This alloy is paramagnetic (not magnetic), hypoallergenic, and offers good durability and scratch resistance. The value … Read more
