I am certain you already know it is a Chinese bead adapted for usage as a Kanzashi or Japanese hair ornament.

But it is #1. Mounted upside down. #2. Poorly attached. #3. Not nearly as fine in quality in material or craftsmanship as the hair pin.

When I see examples such as this, I feel sorry for the dealer who is confusing collectors with adaptations. At worst, it seems to me to be an attempt to fill a demand where there is precious little merchandise. I see it all of the time in the ojime market too. And, the kanzashi and obidome market is suffering in the same way.

Best regards,
