This worth anything?

[Pirul]

Hadn't seen a tourmaline like the one below. Was wondering if it's rare and worth anything. Difference is in shape, as it is more square than the regular tourmalines. Color is basically the same.

I have a sapphire that is similarly different from a normal sapphire, but can't remember where it came from. Does yours stack with other tourmalines?

[Pirul]

No, it doesn't stack.

I have one of these as well. It's a different ID template, thankfully, so I didn't auto-sell it to the jeweler with the rest.
