Great shape and craftsmanship on this vintage pieces of jewelry. The center stone is synthetic tanzanite and it looks beautiful with the aged color of the yellow gold. The prongs holding this stone are large and tightened so the stone will not fall out. The size of the ring is a little larger than what’s shown on the ring sizer because of its square shape. May look uncomfortable to wear but I can assure you it’s not. Retails 2,000$ my price is negotiable.
