Fancy cut Swiss Blue Topaz 12mm 13ct round Buff top loose T1807

Excellent Swiss Blue Topaz. This Topaz has a fancy cut:  the top is a rounded (not faceted) buff top with a satin finish and polished clear round mini-windows to see inside.  This produces a gemstone that seems to glow (instead of the usual sparkle) because it reflects the light internally more than a faceted gem.
