SEDA ROUGH OPALS
OPAL  WOOD ROUGH FOSSIL
This is a boulder opal rough that was tree that has been replaced by opal so you can make out the wood structure.The tree would be from the Cretaceous time 100 million years ago.This material can fall apart some times so some cutters like to treat with opticon to stabilize before cutting.

Also great as a interesting specimen if left natural.

Mined in Winton Qld.

This photo was taken with the stones wet.

All weights and sizes are approximate.

As with all our rough you may return it for a full refund provided it is rubbed or touched in any way-we suggest you look at it with a loop before cutting.
