What GoldenTruth said.
If you go to a Black Lion Weapon Specialist with the ticket in your inventory, you’ll get a special option that lets you redeem them (same goes with other specific claim tickets like Fused, Wintersday, Sclerite, ect).
If you go to the specialist without the ticket, you’ll only get the standard Black Lion claim ticket options. And since Jade weapons aren’t available for normal claim tickets, you won’t be able to see them at all without having a Jade claim ticket in your inventory.
