Reminder that white sand beaches are white because they're primarily composed of the remains of coral shat out by parrotfish

>>3160303Off instinct alone I want to say it's epidote, but frankly there are a ton of pale-green minerals so it's hard to say for sure without being able to examine it directly

>>3160321it's a quite thin crystal buildup on a rock. i bought it like 15 years ago and don't remember myself. i also had an amethyst and a malachite - the latter was beautiful

>>3160338Quality malachite is fucking stunning, yeah; it's a personal favorite. I have quite a few carvings made from it in my collection in addition to the raw samples

>>3160371Hmmmm…seeing it's on a dark black matrix makes me want to swing back towards olivine or garnets since that's very likely basalt, but at the same time the green feels too pale for that.

>>3160511i was gonna make fun of you for this but i've also done this quite a few times

>>3160511Not all sand is like this, there's extreme amounts of variation between beaches. Some are almost exclusively ground-down rocks, some have high concentrations of organically-derived components like shells and coral bits like OP's pic
>>3160519>>3160520>>3160521>>3160522To be fair if you've ever eaten lunch at the beach, you've eaten fucking sand geg

>>3160050 (OP)Sand are basically just chunks of microtiny minerals? Interesting.

>>3160629I mean you guys have shittons of high-quality amber wash up on your beaches so there's that

>>3160647what causes da pink

>>3160651It says Red sandstone but I would think the source material would be something like K-feldspar

>>3160649i meant crushed beer bottles, but we have a lot of amber too, yeah

>>3160682i think it's from the jurassic era when most of Europe was a wetland or shallow sea, and the tree raisin had favourable conditions to harden underwater while not being buried under other sediments

>>3160721Basically this, although it's a lot more recent than the Jurassic, it's roughly 40 million years old
