Oval cut Swiss blue topaz, 17.10 carats, origin Brazil

Swiss blue topaz with an intense blue color, with a luminous and sparkling crystalline luster on all the facets of the gem.

Natural pale blue topaz is relatively rare, however a more intense blue topaz is often the sign of treatment by heating or irradiation which does not represent any danger and which makes it possible to give this gem a stability of its color that will not vary over time.
Very pretty fine stone to mount in a magnificent jewel.
