I am never let down by GemSelect. I love that you get the exact stone you want. Shipping is always in a few days. I have spread the word about GemSelect on social media jewelry creating groups that I attend. This sapphire is going to make one gorgeous ring

I found what I was looking for...had to look up millimeters to inches. It would be nice to see something, like a quarter, in the pix to show relative size. I plan on buy loose gemstones for every month in the calendar
