Casting Moissanite in Place

Can moissanite, a precisely calibrated hand-cut jewel, be successfully cast in place in platinum and karat gold alloys? Ongoing research being conducted by industry veteran and head caster Tony Milad of Hoover & Strong, Richmond, Va., has shown that the procedure can be done successfully using karat gold alloys. Procedures using platinum alloys are showing promise. Because moissanite is known for superior heat resistance, it's a prime candidate for in-place casting. A comparison study to test heat resistance was conducted using faceted samples of diamond and moissanite. Both were placed in a high-temperature oven and the temperature was increased while a flow of oxygen was introduced. As the oven reached 2,012ºF, the diamond caught fire and began to vaporize. The oven was turned off and the diamond continued to burn until it was completely vaporized. The moissanite jewel remained
