Our blown glass rings are quit the rage. Made of strong Pyrex brand glass that the Corning dishes are made of "we all know how strong they are"
Ron uses a table top torch to hand make all the glass. He wore one of his own rings for over a year never taking it off. It finally broke when doing some construction work with cement. So they do have a limit. However one doesn't have to be afraid to wear it daily doing normal activity's.
PLEASE REQUEST THE SIZE YOU WOULD LIKE
The one pictured will not be the one you receive. You probably won't be able to tell the difference though.
Have a great time shopping!
