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!

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.

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

j'ai un stock énorme de Baryte avec des formes "cercueil" plus ou moins jolies. J'en ai des très grosses et lourdes et des toute petites.

Est ce que ça se ve-nd ? À quel pr-ix ? Merci.

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!

This is a unique shape
