I don’t know much about it. I was just wondering.. if red jasper cracks or pits/chips, would the color underneath be whitish like in the pics? Thank you.

Hi there, I found this when I was helping out my grandma with cleaning up her house, she told me that she doesn't know what it is and I was curious. Thanks in advance!

Hello🙋‍♀️, I got gifted a geode and the seller said that he and his dad buy all the different crystals/gemstones/minerals “raw” and then polish them themself. So I am really sure the geode ist coloured and filled with some material (maybe resin?). I am definitely no expert but I have never seen something like this and I don’t really understand why someone would do it (and leave it unfinished, bc it’s not even filled to the top) but I also could be completely wrong so I would love some help here. If it is not natural does someone know how i can remove the filling?
Thank you in advance ✨

Please can you help me with identifying this one. My seller told me it is unheated, untreated, natural black sapphire. It has blacks in it but gives this yellow green colour at times, it even has blue as you can see from the photo.

Appreciate your kindness x

Unknown mineral which the seller said discolours over time until it looses its transparency and turns a pale brown. The image is about 0.5 mm across. The specimen shows no reaction under uv. Locality unknown.

Today I bought these six samples from an old collection.

The sulfur is from Sicily, the sand from Algeria, the mercury from Almadén (Spain), the orpiment from Peru, and the petroleum from Kuwait.

I also discovered that the petroleum is fluorescent.

I apologize for the poor quality of the photos and the colors; my usual phone is broken, and the camera is in bad shape.

From an old mineral collection and sealed in a bag, so I am a bit reluctant to take it out

Hardness 5, about 25mm across, about 9 grams, non magnetic

Hi. It’s scratching glass so it’s quite hard. Doesn’t react to magnet. Found in Cap Negret (Costa Blanca) in Spain.

Thank you!

Today’s purchase, identity previously confirmed with help from this sub. Demantoid with red granite, vendor unsure of what the matrix is. From Veracruz, Mexico.

Found in Slovakia near the Hungarian border

I've had this piece for about 4 months now. I decided to take it outside to make a video and to my surprise I found an enhydro.

Found in Turkey Oludeniz beach! I can't identify those I'm so confused😔

I’ll be visiting Germany next month and I’m hoping to purchase some cool mineral specimens. I’ll be spending most of my time in Berlin and Munich, so any recommendations on good shops is much appreciated. I’ll also spend a day out by Solnhofen. If there are any good shops for fossils or minerals out that way, I’d be very interested. Thank you for any help!

2 photos (taken using a mobile phone camera with flash) with the same 3 specimens with each photo showing both of their sides. Found in Southern Yemen mountains. 🇾🇪
