Antique Amethyst discount Glass and Paste Hat Pin

Beautiful large Victorian era amethyst glass hat pin with 9" pin.
The large purple stone clearly has bubbles upon inspection with a loop.
There is also a sizable internal crack that is not felt on the outside back or front of the the discount glass.
Not noticeable until you turn it over and look from the underside.
Paste surrounds the outside edges. The bezel that the glass amethyst sits in is clearly hand made and hand soldered.
Very nice presentation piece for a period drama.
Top measures 1 1/2 x 1/14"
