BOULDER MATRIX ROUGH 

 

This is a natural boulder matrix from Opalton Queensland Australia.This material has precious opal embedded in the ironstone and usually is easy to get a top polish on.You can cut stones from it make beads or do some interesting sculptures or carvings.I have blasted it was a strong water pressure with a gerni to remove the out side mud and also to loosen any small fractures.This is a stunning specimen as there looks very little colour on the out side. There are some natural fine fractures in this specimen so if you wanted to polish it you would have to treat it. It would look stunning in a shop window!

We have taken a photo of the stone wet.

As with all rough there is a gamble in cutting-we have cut some stunning stones with this material which are listed in our sites. We also have had some disappointments and sometimes  great surprises with a rough that looks like it wont cut. Some of this material if near the surface has fine fractures in it and when you cut it it will break apart.Some cutters soak it in resin to stop this. I suggest you look at in when dry before cutting so if you are not pleased you can return it. 

 

As with all our stock if you aren’t pleased you may return it for a refund provided it hasn’t been touched in any way.
