20x15mm Octagon Stone Backless Sew on Setting in Silver or Gold Plate!
These do fit SW Art #4610.
They have an open back, as shown, and 4 holes.
There are 4 prongs to secure your stone.
The Silver is a bright silver plate.
The Gold is a medium, natural gold.
You would place your stone, and gently bend the prongs in towards the stone with bezel setters or pliers, and it's ready for use!
Do be gentle, as you can crack your stone if you give it a little too much "English" ;).
You will receive one setting in the color of your choice.
