The band measures approx. 12 mm wide at the front, and 6 mm at the back. The stone with its setting measures 19 mm by 27 mm.
This Labradorite ring is ready to ship in a UK size P 1/2 (measures size Q 1/4, which will fit approximately like a P 1/2, due to the wide band). If you would like something similar made just contact me to discuss your project.
Hallmarked at Birmingham Assay Office, with my makers mark according to UK regulations.
