Jim,
  It looks a lot like glass slag from a glass factory.
Nice color though.

To all,


I need the help of a serious rockhound. My travels have brought this 
large
crystalline rock into my hands. It weighs 2.15 kilos. It is a dark 
green, that
transitions to brown with yellow/gold crystal encrustations. The green 
section
is transparent / translucent while the darker composition is less so. 
Using a
set of hardness pencils (points) I have done a scratch test and all 
results show
- 7 does not scratch and 8 does. Locale of origin: Thailand / Cambodia. 
Based on
the scratch test, it is obviously not quartz or glass. My best guess at 
the
moment is a variety of green Garnet, but I am not sure which variety. 
Other less
likely possibilities are beryl or tourmaline but neither comes from 
this area
and I don't think either one is found in a similar size. You may email 
me (Jim)
at: Thai_buyer at yahoo.com if you would like to discuss.  Picture link

Thanks,

Jim
