A 3.00 carat round lab-created strontium titanate rhodium over sterling silver solitaire pendant on an 18-inch Singapore chain measuring approximately 9/16 inch long by 5/16 inch wide with a lobster claw clasp and two extenders - the diamond simulant pendant that delivers more spectral fire than diamond itself. Diamond simulant (lab-created strontium titanate) has a dispersion rate significantly higher than diamond, meaning it produces more rainbow-color light events per carat than an equivalent diamond would. At 3.00 carats round in a solitaire setting, this pendant creates spectacular optical performance at a fraction of the diamond cost. Two extenders for flexible length adjustment.
