Hand crafted Sterling Silver lady's hand ring set with a natural light green Tourmaline cab. The tourmaline measures 6mm x 4mm x 3mm, and weighs .50 carats. The ring is an Art Nouveau design done around 1890, featuring a lady's gloved hand holding the stone. The ring measures about 8.6mm across the hand, and the shank measures about 2.2mm wide and 1mm thick at the thinnest spot in the back. The ring weighs about 3.2 grams, and is stamped Sterling inside. The Tourmaline is a lovely light green color. Ring size is 8 1/2. Splendid!
