Very cool ring which is made of a wire wrapping technique, and uses a nice big faceted Rose Quartz, measuring just under .75 inches across the stone face
the Rose Quartz has a milky almost glow to it
No markings, this was probably hand made by someone in the US, I saw a lot of this craftmanship back in the nineties
when people were really into hand making jewelry and beaded stuff. The wire wrapping is slightly asymmetrical as well which indicates hand made.

Tested sterling silver 

Technically a size 6 on the ring mandrill, but the wire and band width make it fit my finger more like a 5 to a 5.5 (I wear a 5.5 on my ring finger and it goes on but is a little tight)

Unique piece with an awesome stone!
