Yay, dry sanding! There’s not many of us left! Beautiful stone and beautiful job.
Thank you. I like the fast results I get on opal.
Thanks for showing us this, it’s always good to learn & your opal turned out beautifully.
Thank you for your comments. Working with opal has its rewards....and its disappointments.
Thank you for your comment, I am glad this has been educational for you.
There aren't enough opal cutters getting recognition in youtube.
Unfortunately, I don't think there is a lot of interest in opal. Thanks for your feedback.

Stunning!
Yes, thank you.
Much appreciated for the information mate. Every little bit helps as I learn the way of opal cutting. I've got a few nice parcels coming up from CB and LR that I hope to turn into something even a fraction as nice as what yours turned out. Well done.
Thank you for your feedback. We are glad you found our video helpful.

@@ThatOpalGuy thank you for kind wishes, we will win!
Nice work on the finish and well done and by hand is a rare talent nowadays. The sand paper does an extremely good job but has been a cause for me to have weak lungs even though I used masks. It still gets in. My dad also has the similar issues and he never used a mask lol. I have now gone to wet only bemused of my lungs otherwise I would still be using dry. :-). Nice vid Robert
Thanks for your feedback Justin. I do use wet wheels but only on quartz and some larger specimens. I would encourage you to wear a mask even working wet, I do and always have. The particles are still in the mist.
@@diverseopalproducts you are welcome and you are right they are in the mist
great job. looks stunning
Thank you. Using and supplying diamond tools in Australia from Poltava Diamond Tools has been beneficial for us.
@@diverseopalproducts oh, you use our products! thats a pleasure
@@pdtsuperabrasivesexport1818 Thank you for your support Poltava Diamond Tools. You make great diamond products. They allow us to get excellent results on our opal.
WOW I'm 30 seconds in, that piece is an absolute smasher! I'm sure you are going to do a good job with it, but i just want to snatched it from you and do it myself... looks like one of those opals that pretty much cut themselves... so jealous
Its a lovely piece. Wish I had more of them.
One piece masterpiece!
Thank you for your kind words.
opal is so beautiful
Yes it is and I get to cut and polish it. 😀
Like fire and ice
Feels like ice. 😀
That's just breathtaking! I love opals... they're my birthstone. I have a Coober Pedy opal ring that has been with me thru 30 yrs. It's fascinating to watch the process. I would love a big one in raw state just to be able to look at it and hold it everyday. lol Thank you so much. You're so talented!!
Thank you for your encouraging comments, its appreciated. Its nice to know you have a connection to the processes I am performing by owning a Coober Pedy opal ring. 😀
nice job how things change as in you think you will get 2 stones when you start and end up cutting out sand and get one large stone and vice versa sometimes
Thank you. I was quite happy with the result.
That stone was an exception, but i say anything over 20% return in weight is a good job. Your return was 40% which is definitely a credit to your abilities!
Now the counter factuals... i reckon if i had it i would have possibly cut it in 3- approximately half way along then sliced through the thicker half to make two thinner stones... would that have improved the yield? And would the larger stone size offset the lesser combined value of 3 smaller stones? Back of envelope calculation tells me that 3 10ct stones would be epically superior, but you simply wouldn't be able to save that much mass. Break even at 3 8ct stones which would be pushing it.
So it's impossible to tell, but i THINK you made the correct call
Thanks for your thoughts. I never really consider a stone finished until its sold and out of my hands. I keep my options open until that point. If pieces don't sell as they are, I consider recutting them.
Regarding returns from processing rough opal, the standard has always been 30-40 carats per troy ounce (155 carats) with full colour opal. If you are cutting standard size cabochons, you can expect 30+ carats. If you are cutting freeform cabochons, you can expect 40+ carats. There are always exceptions to the rule.
@diverseopalproducts bang on 22% yield.- 7ct for a 30ct stone... give or take. You can discuss strategies etc, but in raw known numbers, you win...
beautiful work. do you sell rough? all the best
Thank you for comments. What type of rough are you looking for? If you can give more information I will see if I have anything close.
Beautiful multi coloured floral pattern there.
Would you leave it like this as a final product. Or would you try to take that little blemish out . Would the risk be more than it's worth to do .
Thank you for your feedback and question. It can be a little tricky with webbing or the presence of gypsum, you cannot always tell when or where it will end. So, trying to chase it out could end with 2 stones or a greatly reduced single stone.
@@diverseopalproducts yes it's when chasing these my anxiety starts .thankyou
Hey there bud! Was looking in the website/eBay and wanted to reach out about some rough parcels?
Thanks for subscribing and your question. What type opal are you seeking? As much information as possible would help.
@@diverseopalproducts I really like lightning ridge knobby but honestly I purchase all types or rough parcels from AU including bolder. I have wheels and a a lil set up for rubbing. Trying to make opal a bit more available to my viewers
@@VendettaProspecting Getting nobbys from the Ridge is not that easy, unless they are evidently low grade. Getting any type of rough at the present is a problem. Its summer and most miners are somewhere cooler. I do have some beginners rough in boulder and white based if you think this would be of interest.
Give opal auctions a try.
You'll get silicosis sanding dry
That is why I say in most of my videos. where I am dry sanding, to use an appropriate dust mask and dust extraction if possible.
Gonna have to grind a lot of opals.
