Received a pair of diamond rd stud earrings, ..90 ct each, as a gift and the quality was very poor. Tried to trade the earrings in at the shop on Kirby Ave and was unable to trade in for better quality unless I "upgraded" for several thousand dollars. I was also given the option to trade for a much much smaller ct. The fact that the "upscale" location sold such poor quality was surprising to me... I went elsewhere and was able to make a trade for an additional $2000 and am happy with my new very pretty earrings!
