My first gem render on my new computer.  It went so quick!  I think it was a 20 minute render!  This is pretty similar to my emerald render, just sapphire, and with vastly improved quality.

Looks very good. I think the real thing would create caustics. :)

Nice one :)
Looks really sparkling - an eye catcher!
Just some proposals in you want to improve your result with regards to realism. You could: 
- change the sharp edges to rounded edges (tiny radius) - gives highlights on edges.
- use a renderer that supports dispersion (diffraction with rainbow colors)
- finding a light setting that causes more caustics around and behind the gem (much try and error - hard work)
- adding some depth of field (render time explodes but 20 Minutes is'n much anyway)
- adding some lens flare effects (some renderers support that)

Happy tweaking!
