This necklace is made up of multiple tiny natural fresh water pearls and is fastened together with an 18 karat gold-plated sterling silver heart-shaped T-bar clasp (where a rod passes through the middle of a heart-shaped pendant). This is a unique, feminine and polished piece, one that will work well with plain tees, ruffle blouses, or even a statement sleeve - you choose!
