|There is nothing more exciting than finding a piece of jewelry that completely melds with your sensibility. The jewelry of Melissa Joy Manning is just that kind of collection, you can trust her pieces are made by hand in her studio in California and NYC using sustainable and recycled materials, locally sourced stones and socially and environmentally responsible practices. This piece is a limited edition, which means that it is one of a kind, fine gold chain which is adjustable to be 16" or 18". This piece beautifully combines 14k gold and sterling silver (the cap on the aquamarine is sterling and the clasp are sterling). The aquamarine is approx. 1cm (including cap) w/a smooth finish. I have more photos of this piece if you would like to see more before your purchase feel free to email.
