I do know they carry black onyx. not sure about the other 2.
I know I've seen the black onyx and the red mercury however they don't get the same thing every shipment so if it's a big seller it will have stock every load if not it will have a stock here and there when the quantity gets low
They carry a wide variety of crystals and stones, and the inventory changes. Your best bet is to contact the store directly.
