 	* 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). 
+* To make 8-bit version, convert to 8-bit before scaling down from 128x128 to 16x16.
+* To use existing Block Shards, keep in mind that for Block Shard Hex Pointed, Object data, mesh name can be changed between "BlockShardHexFlatSide" and "BlockShardHexPointed"
