Opal t-egg
« on: November 22, 2018, 01:48:41 PM »

Solid opal, not fire, but still cool. Big broken egg from a new location hopefully; this was the only one I picked up but I only had about five minutes to look! Will be going back once weather and hunting seasons cooperate.

Let me know if the pictures don't show up, hosting them on facebook this time. The egg came from a place more than ten miles away from where I usually find t-eggs, so very excited for new prospecting avenues! Unfortunately access is even more dependent on seasonal road conditions and other land use, so it might be a few months before I get a chance to go back.

I rock hunt in the Antelope/Ashwood area of the John Day river basin in Oregon. 90% of what I post is from this area, from private property where I have permission to hike and collect. The material I find is for personal use only, I do not have landowner permission to sell. Thanks for understanding!

Try putting a p[piece in water for a few hours and compare it to the rest of the piece.If it takes on a lot of water and clears then look at it backlit by a strong light to see if it is contra luz opal with fire. Alternatively break off a little piece and put  near  a stove or heater for a few days to see if it will craze badly when dried out. When I cut
Oregon opal full time we learned to let it sit outside for a year to see if it would craze. I havfe had the blue opal craze badly 16 years after being cut into a jewelry stone. Have fun and be safe.
