Swiss blue topaz jewelry brings the saturated blue of a clear winter sky to your collection. This topaz variety gets its signature electric hue through a combination of heat treatment and irradiation of natural white topaz, creating that distinctive medium-dark blue that falls between pale sky blue and deep London blue. With 8 on the Mohs hardness scale, Swiss blue topaz holds up well to regular wear. Our sterling silver settings let the stone's color take center stage.
