So many gorgeous stones! The only "complaint" I have is it's difficult to visualize sizes in mm. Perhaps some way to compare in inches?It has been a long time since I bought stones from Gem select, but the process wasn't too difficult.

My only complaint is that there are so many beautiful and affordable stones that I get distracted from what I planned to order.
