Rough (raw) opal pieces from Welo, Ethiopia. These are specimen grade (see explanation below) and are medium pieces.

I have a total of 90 grams of these. Weight of each piece ranges from 1 gram to 10.5 grams. Average is around 3 grams. The entire lot is shown in the last photo. You get a ten gram package.

Want a bunch of these, or even my entire stock? Contact me for deep discounts on wholesale quantities.

These came from a two kilogram lot of "mine run" unsorted rough opal I just purchased. Many of them will end up cut and used in jewelry in my shop, but I have plenty that I'll be selling in raw form just like this.

Untreated. I can stabilize it with Opticon for you on request for a small additional fee and some wait time.

Money from opal sales will be used to help fund my gemstone buying trip to Erongo, Namibia, Africa! If you're a jewelry maker/lapidary artist, trust me, you want me to make this trip :D I will come home bearing awesomeness.

GRADING
________

SPECIMEN GRADE: Suitable for display, wire wrap, etc. May have inclusions, fractures, or other issues which would prevent them from being a candidate for cutting and polishing. Appearance could be improved by careful cleaning and polishing, but I wouldn't try to use them for lapidary work. Some of them have great play of color, they just aren't cutters.

LAPIDARY GRADE: Suitable for cabbing or freeform carving, each lapidary grade piece has the potential to cut a nice opal. In general, this material tends to be oddly shaped, and your best yield from the rough will be achieved by freefom carving. You could certainly cut standard cab shapes from it, but they'd be small. This is really, really nice material and you'll find you won't want to waste it.

Many of these that I've cut produce really nice sized stones with play of color visible from all directions, so definitely consider a 3-D design.

LAPIDARY GRADE B: Suitable for cabbing or freeform carving, each lapidary grade piece has the potential to cut a nice opal. The B grade has much more limited play of color; they all have *some* detectable fire, somewhere, but there may be a very limited amount of it or it may not be very vivid. Good for beginning cutters or those on a budget. It's cheap, but the resulting stones will be less valuable.

PRETTY POTCH: Potch is opal with no play of color, also known as common opal. This grade consists of potch that is actually attractive on its own without play of color. Some is almost transparent, some has pretty colors, some has dendrites - you can have fun and get some neat stones out of this material.

POTCH: Potch is opal with no play of color, also known as common opal. This grade consists of potch. It's most commonly used to make backings for precious opal cabochons. Due to its porosity, this material can be easily dyed. If I had time, I would use this material by staining it slightly and carving it, using it as vegan bone or ivory. It has a lovely texture for carving, and it has an ivory-like sheen. It would look amazing as a cruelty-free stand-in for bone or ivory in carvings, pendants, or handmade beads.

SEASONING
__________

It was sold to me as seasoned for 2-4 years, but vendors in country have been known to wildly mis-state the length of time their material has been out of the ground, so take that as you will. It does seem mostly dry to me. I've found myself wanting to stabilize my own cutting material not because anything I've cut from this vendor/locale has crazed, but because a piece I cut and used as a pendant for a long time discolored due to absorbing my skin oils. This stuff is so porous that like turquoise, it's prone to absorbing things you don't want it to. If you're cutting for jewelry you may want to consider stabilizing.
