Video so you can see how coloration is saturated.

Please look at my rough Indoneisan Reef opals. I need some ideas about value and how to polish.

I know this isn't opal but thought it belongs here since it's a multicolored stone just like opal. It also comes from Australia. It's called rainbow lattice sunstone.

I’ve wanted to cut some of that for years. Can’t seem to afford the stuff though.

Lightening Ridge Black Opal, N2 color and 5/5 brightness. It’s got all the colors. Almost as good as it gets.  1.9 carats  from the LaHoud claims

All I s good Fred, I still enjoy looking at the Aussie nuggets you sent me. They occupy a special spot on my jewelry bench.  Hope all is well in your neck of the woods

I had a question about opals for all of you guys, was curious if the color of the flare has anything to do with how soft or hard the opal will be? In example red would be the softest due to the softness of the wavelength of light vs violet being a very hard wavelength. Just a thought couldn't find anything on it so was just looking to see if anyone had any answers thanks a ton in advance!

Hi Digingd I don't think the color has anything to do with how hard the opal will be. I think the geologic setting would dictate how hard the opal turns out. Was the opal found in volcanic ash like in virgin valley Nevada or in sedimentary environment such as Victoria Australia. Imho  I hope this helps answer your question.

Has anyone been collecting at Opal Mountain in California north of Barstow? Just curious if there’s been any more recent fire opal finds...  We were there a couple weeks ago and just got some nice agates and plain white opal,  but nothing with fire.

I visited Opal Mountain and Opal Hill many years ago. Didn't find any fire opal at Opal Mountain but didn't spend much time there. Storm was coming the next day.

Had much better luck at Opal Hill for fire agates but last I heard they were closed.

Your best chance for fire opal is Virgin Valley, Nevada at the fee dig sites. It's rather expensive and most of the opal isn't stable for cutting but it's a nice experience nonetheless.

Thanks for your reply. I have found a tiny piece of fire opal in Cadiz Valley before, but it may have been a flake from point napping (probably a Native American “manuport”) as there were no others found in the area.  Wish I knew where their source was, but their trading could have covered over hundreds of miles.

Everything I’ve ever read about the place says that the only precious opal found there was found 200 ft below the surface. Any mine entrances have been destroyed by BLM.

I guess I’m going to have to get a better pick!  It’s still a pretty fun place to collect agate there, we got a few nice ones.  Also went out to the nearby dry lake bed to look for meteorites, but a lot of it was actually filled with water!

How were the roads to opal mountain? I’ve never been and had heard the roads were in really bad shape.

The road heading north from Hinckley to the base of Opal Mountain is doable with 2wd and good clearance, but the road up to the summit of Opal Mountain is steep and narrow and has lose rock, you’ be better off hiking it if you don’t have a short 4wd like a jeep with good tires.  Also, Black Canyon is the best way to get to Scout Cove if you don’t want to rough it going the four-wheel-drive route over the ridge from Opal Mtn. It’s a really cool place, you should check it out either way!
