This is a gorgeous Sterling Silver ring, marked 925, TGGC. It is a UK size P, USA size 7.25. 

It has a lovely design, with an oval setting, which holds a beautiful domed Ethiopian black Opal, with a small clear stone on either side.  

It is in perfect, new condition, and measures 3/8ths of an inch long at the front. 

As always, I am happy to combine postage on any items that are paid for at the same time. 

Please message me with any questions, and thanks for looking.
