The Day I always put off until absolutely necessary. It's me using the latest version of Adobe Photoshop and Lightroom. Why? Because they always always try to change enough basic tools and the options to "make it easier" which in this case means to more fully force Ai onto the process. Even though I DON’T WANT TO USE Ai. Arrgh, this simple edit to remove some dust shops and background distractions just took me about 1 1/2 hours. And worse yet, it is truly unclear if Adobe is not automatically converting the images you import into DNG, because I don't see that in any files. What I did find is that all the first images I applied the 2026 metadata I chose are all suddenly in .tif format (yay I selected that) BUT put them ALL into a new folder I DIDN'T EXPECT. And now they are all labeled with file names of .tif photos but the ONE file I exported as a trial run now was really really hard to find since ALL PHOTOS are now there, showing my Date Created as today, and all my original EXIF data, like ACTUAL DATE I created the photo is gone.

Anyway, just to increase my agony, here is a small vversion (for me, pixels 1200 x 900) and I've tried to reduce the photo sharpness to a lower percentage since I always edit photos full size, which is iPhone Pro Max 2998 or so by 3998 or so. Whatever. If this phioto is truly offensive to me as I now attempt to share on Ivory, don't be surprised if it goes poof! I hate hate hate all the Adobe Photoshop and Lightroom changes annually. And where the heck did my Camera Raw app go?

A group of malachite specimens all in vertical images. Malachite comes in so many astonishing forms. These are all shown by the higher end dealer, Marcus Budil. I saw far more malachite from many dealers than is typical. Democratic Republic of Congo is the source for the specimens. You can spot the growing fan base in the specimens shown prominently each year. This is also a big year for fluorite. #Tucson #TucsonGemMinerals #Malachite #Green #Rocks #Minerals #Geology

Crown Emerald Copper, Desert Queen Dioptase!

https://www.mineralcup.org/2025/vote/r4m02

Please vote for the pyroelectric, HOT desert mama! It's so amazing it can look like moss but is electric if you heat it up 😲

So, did someone call #electric #Mosstodon? The most arid deserts in the world have none, but grow moss-like dioptase to make up for it. The world's amazing, so spread the love & vote!
Forbidden #broccoli or green #cauliflower?

Dioptase was first mistaken to be emerald and gets its colour and toxicity from copper. Hence, Emerald Copper and Desert Emerald nicknames! Although it's toxic - no licking! 😅 - the vivid green tones make it great for healing & the heart. 💚💎🧡

Here's some different mossy shapes to spot in different photos, if you want to look toward the ground instead of what you see in clouds! Thanks for voting!

Un vero gioiello della natura, questa piastra combina le tonalità blu intense dell'azzurrite con i verdi vibranti della malachite. Perfetta per appassionati di minerali e collezionisti, rappresenta un esempio straordinario di bellezza naturale e artigianato geologico. Un pezzo unico che porta con sé la magia e il fascino del Marocco. #Minerali #Azzurrite #Malachite #Collezionismo #BellezzaNaturale #Geologia #Esplorazione #MeraviglieNascoste #Marocco #Co

@Kaetchi I am not very knowledgeable about the Congo Copper Belt. Congo has very old copper-rich rocks (the Katanga Supergroup, 700-800 million year-old sediments). Malachite forms when underground water rich in CO2 reacts with existing copper minerals. Congo has not been glaciated for a long time, so that shallow-formed malachite is still preserved.

Others who know more may pipe up or correct what I've written.

#Azurite can form in the oxidized supergene zone of copper-rich rocks. More carbon dioxide favors azurite over #malachite. Our atmosphere doesn't have enough CO2 (yet) to stabilize azurite, but malachite at the surface persists kinetically rather than convert to black copper oxide. Sulfur and other species can modify these relations.

Hence copper roofs weather to green, not blue!
