EYE FUNNY Necklace with Moonstone

EYE FUNNY necklace.
This necklace is lovely and understated with a moonstone top.
The chain is distinctive and has a unique design, making it stand out even though it's simple＾＾

I remember buying it a long time ago at a limited-time shop in Isetan, Shinjuku.
I think it's valuable because this design is no longer available.

I'd like to sell it at a bargain price since I no longer have the box.

Main features and knowledge of moonstone:
Shine (Schiller effect): Light scatters due to the internal structure, emitting a fantastic blue or white light called adularescence.

It is also expected to relieve stress and enhance sensitivity, and it is very popular as jewelry because of its mysterious beauty.
