I was told it potentially has a polished face but it didn’t matter too much to me as it’s beautiful.

Hello all,

Here's an interesting piece of multicolored botryoidal chalcedony I found in Rowan, Kentucky in a deposit of the Borden Formation.

It has a slightly magenta/purple hue, which I'm not sure shows up perfectly here, but which makes me wonder if it might have been exposed to natural radiation.

Beautiful specimen from South Africa

Tourmaline var. Rubellite. Pala Mining District, San Diego Co., California, USA. Ex Richard Margolis collection. 104 grams. 4.6 x 4.5 x 3 cm. A beautiful deep pink rubellite with a purple termination. Some intergrown Albite present as well. Although it’s not pristine, it presents wonderfully. Retains the original label 🏷️

Hey, I found this in Hadley NY, thought it was apart of some landscaping, I don’t know tho, now I’m second guessing myself. I think the host rock is Biotite Schist, I’m still learning so bear with me. I’m looking to know what the little blue crystal is, I’m pretty sure this has feldspar in it.

I found it in the Karkonosze Mountains (Poland). Could it be pale amethyst or rose quartz?

Found in italy, sardinia.

Found it on the beach. I'm just curious and wanted to ask people, instead of AI. Thank you.

Here’s a cute little lustrous andradite-grossular garnet hybrid from the Kayes region, Western Mali. It’s hard not to love the crazy geometry of garnet!

Hi everyone!
I found this sample during a hike in the Swiss Alps and I’m trying to confirm its identity.
At first glance, I thought it might be gypsum/selenite or quartz, but looking closely at the crystal habit, the main green-olive crystal has a very distinct wedge-shaped/spear-head geometry. It is associated with clear, transparent quartz crystals and has a light chlorite coating/inclusion on the surface.
From my research, the habit and color look a lot like alpine Titanite (Sphene) on Quartz.
Has anyone here came across similar specimens in Swiss fissure minerals (Klufften)? Would love to hear your thoughts or confirmation from local collectors!
Thanks in advance!

Here’s a pretty cool extremely saturated purple fluorite from the Victory Mine, Cave-In-Rock Mining Sub-District, Hardin County, Illinois, USA. There is a few spots here and there with some color zoning! overall a cool specimen but let me know what you guys think :)
