This large gorgeous ring features a gold setting showcasing a large, oval, faceted blue topaz gemstone in excess of 12 carats. The stone is openbacked and surrounded by rows of clear crystals. The setting tested at least 10K gold but may be plated. The ring is hallmarked but isn't legible under a 10x loupe. The center stone measures 3/4 x 1/2 inch and appears to be genuine. The ring is a size 8 3/4 and is in MINT condition. A real beauty.
