Round Modern Ruby Necklace on Adjustable Chain - 10mm Round Rose Cut Gemstone Set on Sterling Silver Circle PendantThis modern sterling silver and gemstone pendant features Rose Cut 10mm Ruby. This is a great way to add a touch of red to any outfit. Each sterling silver piece is cast from a hand carved wax, using the lost wax technique. Then, I solder on the bezel, patina the whole piece, sand and polish, and finally set the gemstone as the last step. This pendant comes on a 16 20 inch adjustable sterling silver link chain.
