Platinet - Suitable for casting or fabrication, Platinet is a hard sterling silver, ready-to-use grain containing 6.5 percent platinum. Similar in weight and appearance to 10k white gold, this alloy offers high fluidity for casting filigree or stone-in-place, tarnish-resistance, and no firescale. Polishing results in a high-luster finish, due to the alloy’s improved hardness.
Karat Sterling™ Gold Based Sterling Silver - Karat Sterling™ is a high tarnish resistant, gold based sterling silver. Additionally it is a ready-to-use grain suitable for casting. The alloy offers high fluidity for casting filigree or stone-in-place designs, tarnish-resistance, and no firescale as well as has a comparable appearance to white gold. Jewelry manufactured with this alloy exhibits a high surface luster because of the alloy’s improved whiteness.
