3 Piece lot total 39.3carats (7,86gms) Mintabie Opal Rough pieces to cut. These are dark base with  either  thin red or multicolor lines going into some edges. (Please look at all pictures when considering). 

There is not as much mining coming from the Mintabie area, so availability of rough like this will become rarer. 

The Pieces are 18mm up to 28mm long, 2  are 4mm deep, one is 12mm deep, but that piece has a little sand in the center 

The stones have not been cut, but cutting/dremel carving some areas may yield some colorful stones or wire wrap gems. The pictures are close ups of the stones wet under LED light to highlight color areas. I rotated the stones and one of the pictures has a ruler in millimetres to show size. 

Note: as seen in pictures, this pieces have thin sandstone layer or rough skins

As with any rough, no guarantees as to the quality of stone it may or may not cut. It could also be kept as a specimens. 

This will ship from France regular poste so expect some delay if you are overseas. If you want to purchase multiple items, please let me know before payment so I can work out combined shipping.
