Gorgeous 20mm Preciosa Crystal Rhinestone Shrag Surround Settings in Silver and Gold Plate!
They are 20mm round, with a recess technically made for a 13.5mm Cabochon, though they are pictured with a 12mm flat cab, and a 12mm Swarovski Rivoli, so you be the judge.
The Crystal Rhinestones are Crystal Clear with a foil backing to catch the light.
There is a hole in the center bottom to accommodate a button shank, so you have that option!
The back is flat in the center, with a triangular ripple edge, as shown.
This listing is for the settings only. The cabs are shown for reference only.
You will receive 4 beautiful settings in the metal color of your choice.
These came with documentation from the 90s.
