You wanna see dioptase do something else that's cool?

We haven't much had geode or "hummocky" samples yet, but how weird-cool is that, too? Other things dissolve, only dioptase is left.

Text below from the irocks site. About 12-14 small "cup" hollows or indentations on a shimmering glittering dioptase piece. From N'tola Mine, Mindouli, Pool Department, Republic of the Congo. "This is an absolutely dazzling and gorgeous small cabinet specimen of Dioptase from new finds (2018-2019) at the copper mines of Mindouli in the Republic of the Congo (former French Congo and not to be confused the neighboring Democratic Republic of the Congo). It is a sculptural Dioptase small cabinet piece featuring a hummocky surface just covered in sparkling, sugary, dark emerald-green Dioptase crystals to 2 mm! The brilliant luster of the Dioptase makes them scintillate with any amount of ambient lighting at any orientation! A captivating piece that can be displayed in a few orientations! Interestingly, this seemed to form as a cast, perhaps over "bubbles" or aragonite or calcite that later dissolved away. This was a unique find in the history of dioptase, and they are really stand out objects on a shelf. This is the last of the few smaller sized good specimens we got from the find. Many of them sadly did not make it to the mineral market, but were cut into small pieces for lapidary use and sold by the gram as sparkly jewels for wire wrap and mounted settings in jewelry." Dioptase necklace pendant, or a geode in deep forest green or vivid, deep sea green turquoise, with a deeper green inside it. Raw crystal. It's set on a black something holding it, ready for hanging. 1stdibs site. A geode style piece that seems to be standing up or is upright, opening toward the left here. A round pool shaped lighter rim around the darker indented middle, as the look is with these things. The Evil Queen's mirror style look, but all a glittering green gemstone. Dioptase pseudomorph after Shattuckite(?) from Mindouli, Pool Department, Republic of Congo. "Sparkling hemispherical formation of lustrous transparent green dioptase crystals with no attached matrix. Apparently the dioptase crystallized over a spherical shattuckite formation that dissolved away. Collected in 2019." From the Johnbetts-fineminerals . com site.

Today's ROTD is #Mincup23 🧪⚒️
Cinnabar! Cinnabar is the chief mineral composed of mercury & is a very important ore mineral. Most Cinnabar is uninteresting in habit. Some localities produce phenomenal and strikingly colored red crystals that stand out within a white matrix. I want more raw pieces.
This is the only Cinnabar I have, it's not a very exciting specimen, but the contrast of red and white is very nice. This one was tumbled before I grabbed it, I prefer rocks in the raw as it were. My guess is this is from a massive uninteresting ore deposit rather than a tabular crystal deposit, or whomever tumbled this is very silly. This is the reverse side which has minor red splotches on a white egg shaped stone This is the most striking part of the red mineral bonus cat in the background. It appears as a white egg shape, but much smaller, with rosey red splotches of Cinnabar. This is not my specimin: credit @johnbetts-fineminerals.com This is wild and raw cinnabar in matrix. It forms beautiful crystals and really should be handled carefully as it is literally made of mercury.
