Blue sapphire is the stone of clarity, focus, and calm-and this oval lab-created stone delivers that iconic deep blue in a setting designed for modern wearers. The 18K yellow gold over sterling silver mounting is clean and contemporary, letting the stone's velvety blue do all the talking. The intricate Singapore chain adds visual richness without overwhelming the pendant, and the 18-inch length with 2-inch extender lets you dial in the perfect collarbone placement. Lab-created sapphire is chemically identical to mined sapphire with perfect color consistency-a sophisticated choice for everyday elegance.
