Genuine blue & white topaz gold over solid sterling silver bracelet

This is an absolutely gorgeous genuine blue and white topaz gold over solid sterling silver bracelet. The blue topaz gemstones shine beautifully and sparkle under the spotlight. Tested with polariscope to eliminate the possibility of them being blue quartz (please see the last picture). The stones show Biaxial lines without the bulls eye that is only sees in blue quartz. The bracelet measures over 7.5 inches end to end. It has two catches on each side for extra security. Stamped 925 for solid sterling silver on its back. In excellent vintage condition.
