This ROUGH matrix opal from Andamooka has been heat-treated and faced so that you can see very clearly the colour bars present in the opal. The opal is wet, so you can get a good idea of how it will look when polished. I expect most people will want to cut this material to specific sizes for settings, but you could easily polish it up and keep it in its current shape if you like it the way it is.
Grace and I just finished a new video series that teaches beginners how to Cut (by hand or machine), Heat Treat, and Polish this Andamooka Matrix Opal. Please stop by our channel on youtube and check it out. You can either copy-paste this link:
Or search google/youtube. -" nn Opals How to cut Opals for Beginners."
This piece of Andamooka Matrix Opal Rough was carbonised. The treatment is permanent, and while I have seen lots of great applications of this material in the rough, such as wire wrapping, prong settings, inlay, rough setting, drilling etc. It is essential to understand that if you choose to cut this material into a cabochon or carve it, it will require a retreat to darken the base material and let the opal colour appear as you see it in the pictures/videos. Please see the link below for more information regarding the history and treatment of this fantastic Australian Opal type.
Here is a brief description of the criteria we use when grading the opal rough:
#9 "Craft Material" is not opal that is appropriate for cutting cabochons. This rough is best for Chipping and putting into floating pendants, craftwork etc. If you want some cheap material to set into your concrete front yard cats eyes or have a mosaic in the bathroom, you want to spice up; this might work for you :)
#8 "Beginners Cutting Rough" is excellent for beginners to get used to cutting this material without worrying about destroying great opals. It is a mix of Nobby and Seam opal. It will cut lots of picture stones and low-value opals. You'll learn to cut open nobbies, chase colour bars, deal with sand and get a general understanding of what it feels like to cut opals. Great material for practising cutting lovely shapes and bringing that talent sharp before attacking more expensive colour. We sort out everything with no colour in it, so 97% of this material shows colour, and 3% will be a Nobby opal that may or may not have colour inside.
#7 "Mid Grade Gamble Rough" is excellent to hone your skills and learn to read trickier opals. This material is full of thin colour bars, colour bars that run diagonally through rough, wavy colour bars, tricky sand spots, and blind stones where I can see that there is colour in the rough but have no idea how deep it goes. Very challenging, sometimes very rewarding rough. Sometimes you cry.
#6 "Intermediate Easy Cutters"- exactly that, with an intermediate skill level, you should be able to cut lovely medium brightness sellable opals from this material. They are generally clean, and you should have a pretty good idea about the kind and size of finished opals you will cut from watching the videos.
#5 "Large Single Gamble Pieces" Pretty much what it says on the tin. These can range from beginners to expert level. Cutting big stones like this is a very different skill from cutting small "pointers" or standard 1ct-3ct opals. These are great fun to cut and can be very rewarding if you get lucky.
#4 "Very Thin/Carving" Most of this material is super thin and appropriate for making doublets.
#3 "Gamble Expert Cutters" these look very bright/colourful and show good promise, but I can't see that they will cut a clean opal. The best blue/green material I find in the parcel also goes into this bucket.
#2 "Expert Cutters Clean" will generally give you precious bright sellable stones. They appear very clear to the eye. It looks like the colour bar covers most of the stone.
#1 "Top Grade" this material represents only a small fraction of our inventory. It is the very best material we find. Red on Black, Deep pinks, lovely patterns, strong black opals all ends up in this category. If I yell, "WOW, I want to cut this one!" it goes in this tiny dish.
All opal cutting is a gamble, and classifying is just my opinion based on my opal cutting journey and current skill level.
When you get your rough please look it over carefully, both wet and dry.
