Celestial armor/weapons
Not really. You can get an ascended drop, but generally you craft them.
Also, PvP weapons and armor are totally separate from the stuff in your hero panel. PvP uses amulets for stats (no celestial.) I’m sure you know that, but just making sure.

The only way to get celestial is in certain gear where you can pick your stats. The glorious armor rewards from the pvp track I believe have celestial available. Other than that, you must craft insignias/inscriptions because they are account bound. You can also get lucky on your ascended drops and grab celestial.
Fluffball is right about pvp. Celestial stats were removed from pvp to discourage bunker builds, so celestial builds are now only available in pve and wvw
