Sources from Component ripping/deconstruction:

L1 Proton Opti Pro, contains 1 unit. This is the only component which contains Topaz.

Apart from the above component, Topaz is used to build just two other items:

L7 Oya du Jaund (projectile launcher)

Both of these weapons are drop-only: they are not sold by vendors.
