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.
