Handmade Australia solid green opal art nouveau sterling silver fairy ring

  
By Hypernova Opals / hypernovaopals. 4.07g total weight (20.3 carats). P 1/2 but adjusts from approx. 16mm (UK size J 1/2 or US size 5) to 20 (UK size U 1/2 or US size 10.5). See photo of back for adjustment mechanism.

I'll adjust to your preferred size before sending (please message me) or it's easy to change on your own. It's great for fingers that change size a bit depending on temperature (as mine do)! I fell in love with this ridiculously bright Kyocera Japanese Bello Jelly/Water opal, so I cut it into gems to share with others! This stone is set in an adjustable new sterling silver setting.
