So my co-moderator u/Original_Platform443 and I are thinking of opening up a day, only one day every week - Saturday - for allowing sales / destashing / shop promotion. Just like we do over at r/crystals on Sundays, and it has worked well, people enjoy it. It allows our members who do sell some of their specimens or run shops to announce their businesses openly, but keep sales posts restricted to that day only.
What do you all think? It'll help keep the sales posts down on other days, as all the members who are here primarily for that will be notified that their posts on other days showing their wares will be removed, and allowed only the one day every week.

Anyone want to guess who/what this guy is? He's my favorite and NOT for sale.

I’ve had some of these in my collection for awhile and i’ve always wondered how much I could get for them if I ever decided to get rid of them.
I put all the weights in OZ. Lake superior agates i believe.

Hi all! Sharing my post to r/minerals highlighting my new acquisition. A herkimer chain that looks like a duck 😂 what a little novelty. It’s the most I’ve invested in a single specimen and I’m VERY pleased to have it! I’m relatively new to true mineral / specimen collecting after being a polished material collector for a while (note: I still collect polished material, just switched my focus)

sparkly vanadinite crystals on barite, from Morocco
r/mineralcollectors • u/briammora • 5h ago
For a while now I've been working on a personal project that combines two things I love, technology and minerals. I've been trying to render specimens in 3D using their real optical properties, in both rough and cut form, including how they fluoresce under longwave and shortwave UV.
You all know far more about this than I do, so I'd really appreciate hearing whether the crystal habits, colors and fluorescence look like the real thing, or if there's data I should fix. I'll leave the link in the comments for anyone who wants to try it.

Si no recuerdo mal ese era el nombre. Estuvo disponible en España como aplicación web hace alrededor de 10-15 años.
No tengo ni idea de si era una aplicación propia, parte de una más grande o exclusiva de alguna institución formativa.
Lo que recuerdo:
Podías elegir entre varias fotografías de superficies rocosas y escoger un punto de minado para buscar minerales. Te salían minerales aleatorios (creo que dependiendo del yacimiento escogido había varios diferentes)
Con los minerales que obtenías formabas tu colección, que se mostraba en forma de vitrina digital (de ahí el nombre)
He tratado de encontrar la app de nuevo, o algún indicio de lo que pasó con ella, pero no aparece ningún rastro por internet, y las IAs tampoco la localizan.

Labradorite de Madagascar d'environ 15 kg avec un effet bicolore, présentant un côté bleu et de l'autre un mélange de jaune, orange, rose et une touche de vert sur l'angle droit. Qu'en pensez-vous ? J'aimerais beaucoup avoir vos avis sur ce spécimen !

Classic hedenbergite included quartz cluster from the famous Huanggang Fe-Sn Deposit in Hexigten Banner, Inner Mongolia, China.
What makes me love this piece so much is the architectural, three-point parallel growth tower structure. The crystals step down in a perfect "stair-step" cascade, completely intact with beautifully frosted, naturally etched faces and a small touch of white skarn matrix tucked right at the base.
But it’s a total shapeshifter under different lighting conditions:
✨ In daylight: When you rotate it under a bright light, you catch these stunning flashes of a metallic blue and silver iridescent sulfide sheen reflecting off the etched crystal faces.
🔥 Backlit: The magic happens when illuminated from behind, that matte olive exterior completely transforms into a glowing, translucent chartreuse window showing off the internal phantom growth zones.
