+To make a Gem:
+* If you are making a new gem, I recommend making surface imperfect as follows (avoid Edge Split since it breaks edges into two lines, leading to problems with further modifiers and possibly with refraction or other light paths):
+	* Make a gem
+	* Tools, Smooth
+	* Add Modifier, Subdivision Surface, simple, View: 3 (that will be applied), Apply
+	* Go to edit mode, and select any edges that should be sharp, and click Mesh, Edges, Mark Sharp
+	* Object Data, check Autosmooth
+	* Change angle (can be all the way up, such as 90, if you did mark sharp on all edges above)
+	* Add Modifier, Displace, Add New, click "Show texture in texture tab" button to the right of it, change it from "Image or Movie" to Musgrave Multifractal, Intensity around .3, Size 2.0 or a little more than the size of the gem, then go back to Displace modifier and change Strength as needed (may have to be negative especially for some Musgrave patterns).
