I was playing around with the Dream Avatar maker and I came across an item, Chest Jewel. It comes in various colours.

So I went to the marketplace to see if I could locate it. But when I did, all of them had no Sales history, no shop link no nothing.

Is this an old rare item? Or is this some kind of glitch?

Could be an item not released yet, or one of the colours from a Pirate CI. I'm not 100% though and likely wrong.

Are you talking about this item? < it goes on the chest?

If so, what that actually is, part of a multi-item called Jeweled Bows
You can find them in accentuate for 365g

OH! That makes sense. Thanks Seito <3 I thought I was going crazy there for a min.

No problem. :3

Ah, Seito got it, good.
