Eberron: Which Dragonmarked House would sell Speaking Stone?

@WalrusAboveHey @HellcowKeith it was suggested on Speaking Stone that Cyrans used glamour magic makeup. Which Dragonmarked House would sell these? The houses don't do EVERYTHING. Zilargo is the main source of glamerweave clothing, so probably they'd do makeup as well.
