The diamonds that are listed are just a partial listing of our inventory. We do not over inflate our inventory list with other people's stones, like some other web sites. Our inventory changes daily, we finish new stones as well as sell stones everyday, we try to update the list regularly. If you do not see what you are looking for on the list, call us at (888) 825-1233 or 212-819-0336 and we will tell you what is in stock at that moment. For diamonds over 2ct please call for our current inventory.
