I had to replace a stone out of one of my rings for my son to have an engagement ring made for his future wife. I found the perfect stone for my three stone ring to replace the center stone I had taken out. I found an absolute gorgeous sky blue sapphire which is stunning in my ring. I get lots of compliments and the appraisal I got showed also that the quality and value of this stone was in line with the Gemsy description on their website. Ernie was very helpful. Will definitely shop there again and recommend Gemsy to my son and to my husband...
