A loose natural Swiss-blue topaz of 5.30 carats, irradiated to achieve its colour and listed as a custom cut not made for commercial use. It suits loose-stone dealers and jewelry makers who sell treated blue topaz. Check the cut and the purple tint noted in the colour field, since the listing says purple rather than blue, and irradiated stones are generally sold as treated.
Estimated flip margin and comp range available with Pro. Summary may occasionally contain inaccuracies; check the full description before bidding.
