GovAuctions Summary

A loose 6.10 carat natural Swiss-blue topaz, listed as purple in color, irradiation-treated, with an excellent lustre and a custom cut. Loose gemstone dealers and jewelry makers who set stones sell this kind of piece, and the custom cut limits how easily it fits standard settings. Before bidding, confirm the color from the photo, since the listing says refer to image and the treatment is disclosed as irradiation, which affects resale value.

Estimated flip margin and comp range available with Pro. Summary may occasionally contain inaccuracies; check the full description before bidding.
