Platinum Jewelry

Platinum can easily be considered the ultimate in precious metals. With a purity generally between the 90 to 95-percent level, platinum alloys are commonly combined with other rare platinum group metals.

Platinum 95% Ruthenium 5% — This has a long track record as a reliable casting material with good hardness and working characteristics.

Platinum 90% Iridium 10% — This is a great all-around alloy that will not oxidize and has been widely used for years in both casting and fabrication.

Platinum S+2 — This is best used for tension set pieces or other applications where very high strength is needed.

Palladium Jewelry

A metal that is lighter than and about half the density of platinum, palladium is ideal for earrings, necklaces and other jewelry that could be too heavy otherwise. Palladium rarely causes allergic reactions, making it an idyllic alternative metal for those who have adverse reactions to the nickel alloy used in white gold, for example.
