GemsNY is the only company I know which has such a large selection of GIA certified rubies. I was looking to purchase a 2ct untreated ruby. I looked EVERYWHERE within 50miles of my house and was able to find only 1 jeweler who had 1 ruby which was untreated. He asked over $35,000 for the ruby and didn't have any certifications on it. He said he could get the GIA done in about 4-5 weeks if I put down a 50% deposit on the ruby. I didn't feel comfortable putting down $17,500 and having to wait a month. So I started my search online and found GemsNY had a huge selection of GIA certified rubies. Also not only the selection but the prices were unbelievably less. I ordered the ruby with one of their settings and received the ring in about 1.5weeks complete. I cannot believe the difference in price and quality of the ruby. I just had to go back to the jeweler to make sure. I saw both the rubies next to each other and actually they both looked similar. However, I paid $14,500 for my ruby compared to $35,000 the jeweler was charging without GIA cert. Also it helped that GemsNY ruby already had a GIA cert with the stone so I didn't need to wait.
