Obidome Natural Stone

I am listing several kimono-related items, including obidome (sash ornaments), obiage (sash sashes), obijime (sash cords), and obi (sashes).

This is an old item. It is a natural stone, but it is unclear if it is onyx or something else.
As a bonus, I will include the obi jime shown in the photo, so please leave a comment.

Approximate size:
Height: 1cm
3 x 1.5cm

There is a small chip on the back as shown in the last photo.
