Crown Metallic Ring with Crystals

This gorgeous metallic ring features 3 crown points (like the prongs on a royal crown) with crystals embedded into the middle prong. There are no markings anywhere to indicate the designer or the metal. The inside circle is just under 6 centimeters in circumference. I think that makes this ring between a size 5.5 and a size 6. The middle prong of the crown is ~1.75 centimeters (~0.66 inches) in height. I don't have the jewelry box the ring came in, but will pack it safely for shipping. Please let me know if you have any questions.
