We have had 0.8 carat Sapphires set in a solitaire setting. These sapphires are untreated and show interesting inclusions and colour variations.
The band is sterling silver. The ring can be stacked with other rings. Also as the band is thin, be aware that ring can fit on more easily than thicker rings so the sizing might seem generous.
there only two sizes left - 6.0 / 6.5
