Abstract
Synthetic gemstones are produced by growing single crystals of silicon carbide, fashioning the silicon carbide into gemstone cores, and thereafter depositing a thin coating of diamond on the core.
Claims21
A gemstone comprising a core of silicon carbide having a coating of diamond.
A gemstone comprising a fashioned core of transparent, monocrystalline, synthetic silicon carbide having a deposited coating of vapor phase-grown diamond.
A method of producing a composite gemstone comprising the steps of producing a gemstone core of synthetic silicon carbide and coating said core with a coating of diamond.
A method of producing a composite gemstone comprising:
- growing a single crystal of silicon carbide by depositing vapor species containing Si and C on the growth surface of a seed crystal;
- producing silicon carbide gemstone cores from the single crystal;
- and
- coating the silicon carbide gemstone cores with a coating of diamond.
A method of enhancing a silicon carbide gemstone comprising the step of depositing a coating of diamond on the surface of the silicon carbide gemstone.
