It feels a little empty around my neck area, but I can't think of anything that would fit there. Does anyone have any suggestions for me? :3

Maybe the green aurora calliope choker? Although it's more silver than white. I don't know what else to suggest.

The clover pendant from jewels dream.

There's this one necklace, that's the appropriate color, with multiple bands.
And it might work out nicely with it.
I believe it's called...
the "Necklace of Longevity"
