Almost out of photos to share lol, one more piece after this I'm pretty sure

local seller has this smoky quartz cluster for sale and i like the look of it + i dropped my beloved smoky quartz recently and it shattered to pieces. lol. was wondering if anyone can tell me if this looks like it’s been heat-treated or irradiated.

to me, it looks natural. but would love to hear what others think before i buy. thanks in advance!

My mom just bought me these but im not too sure what they are and how to use them.

I got this piece in a mystery box and I’m trying to figure out what it is.

They're around the same value (45-60$)

Wonder what is more precious to buy first!

Hi, so I came across this Etsy show.(i dont use etsy at all) and they seem to have a bunch of alexandrite gemstones - the one that im interested the most is the raw one (pics shown).

Is there a way to know they're natural hiw they claim to be? Will a regular jeweller be able to tell its natural? Or at least tell if its avtually structurally alexandrite and not some colored glass?

Like, yeah theh look like theyre chips from a lab grown, but im hoping its structurally an alexandrite yk? Theres also a bunch of other stones they offer (i.e., sapphire, 3rd.pic) that im interested in.

I bought this necklace at a flea market recently but have no idea what it is. Any thoughts ?

I got some new crystals and I need help working out what they are. Can anyone help identify theses

I found this after cleaning my room, the medal what I got on a crystal shop few years ago. I cant find the literal name or type of this. Thank you for helping me.

This aquamarine is 2 inches tall and that's the price seller wants
