it's soft... drilling isn't a problem... lay it down on a towel and slowly drill in with a small carbide drill.. then increse the drill size... dribbling water on the drill while moving it and out to keep the hole wet/slick/and cool is always helpful...
here's a few care tips... if it is indeed serpintine...

I was going to tell you that my foundtion was a bare minimum for it... but as it's smaller... it's likely about right ..you could also decrease the depth of the hole in the piece to maybe 4-5 " now Dia down to maybe 3/8-1/2"
it would surely break apart if it fell over... then when you epoxied it back together .. it would have more of a veining look like marble..
it looks sweet though... congratulations... beauty and a joy forever
