A 3.00 carat round lab-created strontium titanate 18K yellow gold over sterling silver solitaire pendant on an 18-inch Singapore chain measuring approximately 0.56 inch long by 0.31 inch wide with a 3.5mm bail and lobster claw clasp with extenders - the warm gold version of the diamond simulant solitaire pendant. Diamond simulant (lab-created strontium titanate) produces more spectral fire than diamond itself - its dispersion rate exceeds diamond's, creating spectacular rainbow light events. At 3.00 carats in warm 18K gold over sterling, the pendant combines the stone's extraordinary optical performance with the warmth of yellow gold. The setting amplifies the stone's fire through warm contrast.
