Vintage Pearlized Blown Glass Celluloid Pin Rare

This large sized pin was created from sixteen 12mm blown glass globes with a pearlized finish.  They are nestled on a molded celluloid base that was painted gold.  Amazingly, all of the nacre/pearlized finish is intact and there are only tiny scuffs here and there that are barely noticeable.  Despite its size, it weighs less than 1/2 ounce.  I am simply amazed at the condition of this pin.  The clasp is a c-clasp which is often seen on celluloid brooches.  

Condition:  In excellent condition with a small amount of gold paint rubbed off of the back.  Some of the globes are glued to the base with the holes a bit off center which cannot be seen from the front.  All the glass is securely fastened to the base.
