I LOVE this ring. The setting and stone sits about 8mm. It's a simple but elegant piece. The blue it's a deep blue. For those reviews who complain it being fake, this is simulated sapphire. For a real sapphire this size and clarity it will run you at minium 3K USD, not under 100 USD. I wore this everyday, not night and the stone just came off a little over a year. FYI, I use antibacterial wipes and wash my hands constantly (work).
