Ascended Jewelry
Then you have dailies and monthlies with laurels.
Oh and you can also buy them cheaper with badges of honor.
Fractals can only grant rings. Guild missions only grant accessories.
But they should add accessories and amulets with pristine relics (fractals). It’s stupid only rings keep dropping and that only rings can be bought in fractals.
If there should be another way to acquire them, it should be by crafting, just like ascended weapons, with Jeweler. I’m pretty sure we will see it soon though, with ascended gear following.
