Comment: A rare blue spinel with no grey though not a Cobalt-Spinel (at least not chemically, even if it has the looks). For the unwary new-comer: Distinguish between 'Cobalt-Spinel' and 'cobalt-blue Spinel'. This 0.65 is cobalt-blue spinel, this is true Cobalt-Spinel. Either can be great or lousy, but as a rule, Cobalt-Spinels are more costly. Handshots show 'Medium Dark 80' best in relation to skin color; not a funny little sparkler but a dense hue between ultramarine and, well, cobalt blue. Vietnam has long been a prime source for blue spinels, both Cobalt or only cobalt-looks. Slightly rectangular, which could be used cleverly to sneak optical length into a setting. Precision princess- a.k.a. scissor-cut. As for its inclusions, note in the sideimages how luckily vertical they all sit to the table, rendering them pretty invisible from the front (lens only). Roughly 5x5mm will fill a slender ladies' ring up to size five, add a halo and we can make it a six or seven. Like Kashmir-blue sapphire this is not a fast-food gem but an ever more elusive treat for demanding individualist who'd rather adapt size to budget than to look through a sad window or make other compromises. As all gems from this humblest of all websites, it comes with free IGI report, grading papers, global shipping, WLT rainforest certificate, support for NhRP, and dedicated personal service*.
