This 14K yellow gold Mateo L initial diamond necklace is handcrafted in the United States with a delicate chain, lobster clasp fastening and an emerald cut crystal pendant with a pavé diamond initial underlay and border. Attesting to its exquisite craftsmanship, Mateo jewellery was selected to be featured and sold at the Smithsonian Hirshhorn Museum of Contemporary Art, making this necklace quite the labour of love.
