The brooch from the 30 man raid is currently tradeable I believe this was fixed as of 01/03/2017 @Spacecats @Denommenator @CobaltDragon @StarSprite @Malrok

Could you grab a screenshot of the Brooch being placed into a Trade Window ?

I believe the description had always stated "Untradeable" , but the properties weren't configured correctly until the Tuesday Maintenance we just had.
