This solitaire pendant necklace is crafted in sparkling sterling silver featuring an emerald-cut, four prong-set, flickering lab-created blue sapphire gemstone in a charming heart detail setting. Polished to a brilliant shine, this solitaire pendant is hung on an 18-inch cable chain and secured with a spring ring clasp. Lab-created gems replicate the growing process of their mined counterparts, creating precious stones with equivalent optical, chemical and visual properties.
