Opal spinner ring

It's so hard to get a decent picture of Opals, the fire never reveals itself, they're much better in real life. 
These ring are 8.5mm wide sterling silver with a line/ bark texture.  The spinner is 
1.5mm round silver and the Opal is 4mm Ethiopian. These opals are AA+ and absolutely stunning when they catch the light. 
Made to order so please let me know a ring size and allow making time.
