Whats Beneath The Mud? Queensland Boulder Opal Cutting (Nick Hoops Rough Boulder Opal) 

2 stones after slicing and separating that crack? Ty as always for the video and the FB community Roy.

FINALLY!!!!!!!! HELL YES!!!!

That is really pretty. Love the lilac colour in it.

That's some stunning color, it compels you to keep looking at it cos you get subtle variations of color when you view it from different angles, like that purple that showed up at the end, mesmerizing.

Nice one Roy like always Dope musiq starting at 8:00

Beautiful!

It's so satisfying watching that mud come off! Turned out really nice for only going up to 3000!

nice colour, the bolder looks nice to cut & work with. good stuff m8👍🎩🇬🇧

Pretty good Roy, I think that matrix side may turn out pretty good mate, some nice colours in amongst the iron stone.

Nice job Roy, those fractures are annoying, but part of opal I guess. I have a few nice big stones that have ended up as nice smaller stones.😀

Very nice videos and explanations, thanks for that! Best vibes from germany mate!

It is very messy but really beautiful. Great job Roy.

Thank you for showing how to cut boulder opal! I never got a straight answer of how to display the opal from others.

Great video Roy.. Is that the new camera? Looks great. Nice colour on that Boulder definitely pinfirey 👍 nice flashy colours...

thanks for this mate..ive got a lot of colour like this but wasn't sure what i could do with it..good to see a few little imperfections doesn't really matter in the finished stone..

After watching you i just bought my own boulder ship to ameriaca 😄

Nice piece with a good colors.

Really pretty! Wish the green had emerged a little more. Great job!

I love the shade of blue in this 1. Its hard to believe its been 2 years man time flys bye

I probably would cut two smaller stones out of the blue part, which are then without fractures. This would also help to get a flatter angle on the individual pieces. And maybe one could even get an thin 3th piece, but I probably wouldn't do that to save more of the 2th smaller blue stone.. But that's not easy to tell by just seeing it in a video, not knowing the dimensions. I'm sure you will find a good way.

Looking at the stone with the blue on the top it looks ks good as a picture. Perhaps keep the whole thing as a pendant

It's my colors! (Blue, blue and blue) Hey about these slices I've seen a short of a guy slicing with a diy fixed flex shaft and a diamond disc (two pipe holder screwed on a wood desk) some asian jade carvers also use the flex shaft screwed to a table trick but I've never seen someone use it as a trim saw. Just need a drip to it.

Hi i have an opal like this one im in port Vincent SA im yet to tackle it mine has electric blue purple in it and its a black opal

😍😍😍😍😍😍

slice its straight edge on the crack and make two small stone, possibly pairs!

You helped me learn an unspoken trick . Do not wipe the mud off constantly, it holds water well. Only wipe when you need to see details.

Will silicone carbide or aluminum oxide work for grinding these? Will nova tips work on sapphire too? Cause I'm a madman for Aussie gems. Got some Rubyvale high grade rough sapphires, working to get some boulder " gamble rough " And looking for a good price on a small parcel of lightning ridge knobbies . I'm a newbie so I'm not entirely sure about what works and what doesn't

Nice bit of colour mate

Hello again, Roy. I just got 1.3kg of boulder opal which is all boulder and no opal. It came with a gift of a piece the size of the one you worked on in this video. That piece has about as much white as you have blue here but it's pure white with a little smear of yellow and it looks like a little bit of fried egg landed on it. What to do with it, any ideas? The seller is on Facebook and tried pitching me another "parcel" with more of the same, plus a piece with a hole for a string through it, for another $270. I know that you won't get anything "precious" for that price but how can they list pure boulder as boulder opal? I expected little hairline veins of colour at least, did I have my hopes too high?

Where do you buy These Nova Tips?

Please tell me you did not pay good money for that terrible backing music !
