What could be sweeter than a diamond that kisses your collar bone. The diamond kiss necklace features an off-center, mini bezel-set diamond, perfect to layer with all your other jewelry or make a minimal statement on its own. We love this necklace with a charm or two, as well! Diamonds are the hardest naturally occurring substance on earth and formed over a billion years. They have long been a prized gemstone across cultures for their brilliance and fire, often symbolizing love and prosperity.
