This .950 platinum casting material, alloyed with ruthenium, delivers a bright white, dense and durable precious metal for high-end jewelry pieces. Casting platinum requires the same steps as casting gold, but the process is performed differently because of platinum’s distinctive properties, including its extremely high melting point. Pieces cast from this material may be quality-stamped as "950 PLAT." Be sure to request a technical specification sheet about casting with platinum. Casting metal, because it comes ready to melt and pour into your mold, is fast and efficient to use and, because it is professionally produced, you can count on consistent, repeatable quality and composition over time.

Priced by pennyweight (dwt.); minimum purchase is one piece (approximate weight per piece is 2.3 dwt.).
