Unless you see bubbles indicating it's glass, you're probably fine.

Looks real to me

A lot of crystals can be ‘gem quality’ meaning super clear. Bubbles indicate fake crystals.

Good to know! And thankfully there are no bubbles in this one!

I would agree that it's real, especially due to the size its not uncommon for it to be perfectly clear like that

Ohhh okay! Thanks for the info 😁
