The lavender stone in this pin is round, 10mm, and almost that deep. The stone has inclusions, similar to those seen on a crystal ball. These offer considerable interest, and fire, to the purple stone. It is set in an open back pierced sterling silver frame, 15mm wide, and 20mm high. The back is marked "STERLING", the pin is 2 3/4" long, and weighs 3 grams, without the clasp. The spring loaded clasp is marked "HOLD-ON, Pat#3009". The silver is tarnished and could polish to a bright shine.
