The color of the topaz is a gorgeous deep blue.  Cushion cut, checkerboard cut.  High sparkle, excellent size.  Noticeable--not too small, not too big.  My only complaints are that the sterling silver posts arrived bent and the backings are slightly tarnished.  I was able to mostly straighten both of the posts out myself, but they are not perfectly straight.  Came in a simple silver box (not the nice black velvet one another customer showed on his video).  If the posts had been straight and the backings not tarnished, I would have given these earrings a 5 star rating.
