These are called "Stacking Rings". They are meant to be worn all together on one finger.
I recently learned how to do " Flush Setting". It is when you set a rhinestone into the metal so it sets flush with the top of the metal.
These rings are made with textured wire, beaded wire and twisted wire. There is a silver circle on each one that holds a rhinestone. The top one has a garnet, the second has a sapphire, and the bottom one has a cubic zircon in it.
$210.00 together size 8
I can custom make these.
