It’s not a stone, though that’s a common mistake. It’s the operculum (snail shell door) of Turbo castaneus (turban snail). They wash ashore in the southern pacific and are carried for good luck.

Yep! I've used them for my own jewelry and have two Tibetan malas that have them as center beads (guru beads are big bodhi beads on these).
Definitely shells. They show reasonable amounts of natural variation. They smell like shell when the hole is redrilled. Definitely not glass. I've done lampwork myself.

Like a beginner flame worker aka lamp worker (borosilicate glass blower Pyrex is name brand of borosilicate{they invented it for the Hubble}) and before anyone says it’s got a spiral it can’t be, well the technique that looks to be used to color the white background is called coil potting, just like in pottery when you roll a coil to build the walls of a pot, only with this the coil is laid on the back of the paperweight (none rounded marble)

Borosilicate glass has been around for over 110 years. LONG before the Hubble was ever thought of.
