My mistake...silly me. You're right, to the best of my knowledge, there's no such thing as a bezel cut. My brain was just thinking of a flatter cut stone with the setting either even with or raised around it, instead of prongs, so that it's protected from the sides. I can't handle high settings for everyday wear, as I hit them on everything. The only one I own is a MASSIVE mystic topaz cocktail ring, which I pretty much just bought because it's unbelievable ostentatious.
And I do agree with you...cleavage, inclusions, etc. are all things to look for. I actually didn't know emerald had so many problems...I'll freely admit precious gems are not my specialty.

Hardness isn't the only consideration. A hard stone is resistant to scratches but it may still fracture with a hard blow or be too brittle for daily wear.
As this page explains:
Durability
The two most familiar qualities of durability -- hardness and toughness -- are often misunderstood. Hardness is resistance to scratching or piercing. Toughness is resistance to breakage. The combination of the two largely defines the durability of a gemstone.
This guide explains the durability of gems.
This site is excellent for looking up the toughness of any particular stone.
This page does a good job of explaining the factors that make up a stone's durability: hardness, cleavage, partness, brittleness/toughness, thermal shock, inclusions. It explains why an emerald has a toughness rating of fair to poor, even though it has a hardness of MOHS 7.5-8 because it is susceptible to thermal shock and it is heavily included, which causes it to chip easily. You can look up any stone on this site and see both it's hardness and toughness rating.
I've never seen a bezel cut before. Is it a special cut for a bezel setting? I think they can put any cut of stone into a bezel setting. I was actually thinking of a concave cut myself, either round or oval or cushion. I fell in love with the concave cut when it was brand spanking new way to cut gemstones about 10 years ago, so I think that's what I want! I'm Richard Homer's first fan. :tongue:
