Red spinels larger than one carat will sell for a premium, and Myanmar (Burma) traditionally produces the finest quality stones. A 3-ct red spinel would make a beautiful ring stone but has a smaller market than a blue sapphire. 18k white gold ring with a cushion-cut, 3.09-ct Burmese spinel and 38 full-cut diamond accents.
