Deep color! 3.11ct cobalt blue Sapphire set! Heated only!

This fantastic 23 piece collection of sapphires is heated only, no dyes, no fillers, just natural sapphire. They have highly sought after cobalt blue hues with preferred medium saturation, strong tones, and are all wrapped in excellent lusters with SI to I1 clarity. They are well matched in size, measuring 3mm each, and have a Mohs hardness rating of 9 out of 10, making them perfect for setting. They were sourced from Kanchanaburi, Thailand, and are stunning examples of pure sapphire.
