Emerald

Emerald crystals embedded in calcite (or something alike). That's not my first gemstone, but I'm not geologist so I'll be glad to hear crits and comments about color, shape, bright...
I've found I really like to make this kind of renders, they aren't easy and it's a great way to improve and master the render engine. Not the best modeling but materials look good enough, I'm happy with the result.

Hope you like it!
