Obsidian can't be processed into those bloody sunset gems.

You said that the better pick-up and binding were dropped by FB, right? That's not negotiable. There is also the selection binding, that is, the stones cut by jewelry professionals and the equipment cut are the only ones that cannot be traded.

Cutting a gem is to give someone a stone to cut for you, not to put it under it, but to give it directly to others, which is different from enchantment.
