Good afternoon, @theredspinel! So judging treatment can be a bit difficult to do through photos. And, in person, it's really sort of an intuitive thing after handling lots of turq over the years. But I will try to put it into words. Color, luster, and matrix (if present) help me in analyzing a stone. I'll use kingman as an example. It comes in pure blues, but they're typically a vibrant sky shade when untreated (it naturally comes in dark blues too, but that's another story). When kingman is impossibly, electric blue, I typically find the stone is treated. Gem grade (hard) natural turq does take a high polish, so that in and of itself is not an indicator. But the finish will look more glassy when natural, and color depth will be crisp. When stabilized, the color may look a bit "translucent" with a gel-like depth, and the finish may appear "plasticized." The same might be true for the matrix (the depth of color may be altered to, as if the mineral were wet.) Does this help at all? I may try to post photos of examples.
It does help, it all helps, so thank you very much for being so patient with us! And good afternoon/evening to you too it’s night time for us so one more episode on Netflix then off to bed! And oh my… consider that ring being considered
ETA: now I’m just being shameless… I found a stand of small white water that’s a bit more sea greeney blue/teal… can I get your opinion on this pretty pretty please!
