9ct White Gold 1.57ct Round Checkerboard Blue Topaz Stud EarringsTwo checkerboard cut blue topaz gemstones make a beautiful pair of earrings that catch the light at every angle. With a wide and shallow cut to the stones, they appear to have a translucent effect when worn on the ear. With a combined weight of 1. 57ct, they are a great pair of earrings to be worn everyday, but can also be dressed up when worn with other checkerboard pieces, such as our 9ct white gold 4. 54ct cushion cut blue topaz ring.
