Until now, Exotic weapon and armor ornaments were rewarded through Bright Engrams and purchased with Silver or Bright Dust at the Eververse kiosk. Starting December 7, Exotic ornaments will be available for purchase under the gear's cosmetic section in the inspection screen. For armor, players can also use the Appearance Customization tab.
Eververse will still sell ornaments so this change doesn't make the store irrelevant, but it makes it easier for players to discover new ornaments. Bungie also added in the TWAB that "Featured ornaments may be purchased with Silver. If the ornament is available for Bright Dust on a given week, it will also be available for Bright Dust on the inspection screen." On Twitter, Bungie explained that ornaments will rotate throughout seasons.
