Inspired by the universal symbols, shapes and stories that transcend cultural boundaries. Handcrafted in 18K Yellow Gold, White Diamond, and Emerald, the Universum Petite Pave Diamond Studs with Center Emeralds from the Universum Collection represent the universe. Concentric circles have appeared throughout the world and across eras, etched in boulders in the Sahara and found in valleys in Arizona. ALMASIKA's Universum symbol consists of delicately sculpted circles radiating from a common center set with a single stone.
