10.6ct Oregon Sunstone rough shiller with 1.5mm hole

This piece of Oregon Sunstone rough is very special.  It has an incredible schiller effect so dense it would've come out "sleepy" if faceted into a gem, so I thought this was the best option. 
There is a chip where the drill bit broke through on the back side,  but regardless,  as a rough stone it's a thing of beauty and someone will make a gorgeous pendant out of it.  I drilled the hole so that when it's hung from a strap or wrapped, the shiller will be the first thing seen.  It's an amazing pattern.
