I know these aren’t particularly rare or special, but it’s special to me and the first mineral I bought since collecting again. It’s quite tall and has a custom stand so really want to put it back together. Left it in my checked bag and it broke, so really looking for ways to put it back together. Was thinking of some kind of black epoxy or something, any recommendations would be greatly appreciated! Also if there are any suggestions on how to stick things back as well, given its oddly shaped and weight I imagine it may be awkward keep its shape while drying.

Hello all! In this video I have two spinel that kind of have me scratching my head. I think the red triangular spinel is a macle, and the pink one is a macle twinned with an octahedral spinel.
Sorry for poor video, my hands are a bit shakey and it wasn’t wanting to focus on my first couple of tries.
The last thing I want to do is misidentify anything that I have because it might be in someone else’s hands one day in the future.

Here’s a fantastic specimen from the Elmwood Mine, Carthage, Smith County, Tennessee. It features gem sphalerite on hydrothermal dissolution fluorite, as well as some clear calcite. I absolutely love when minerals form coatings on top of other minerals!
