Antique Optical Lens - Gilleaindreas

I made another one of my illustrations called "Gilleaindreas" into a necklace on etsy. This is a vintage optical lens from an old optometrist’s trial lens sets, circa early 1900’s. The lens is gold rimmed. The illustration is printed on archival paper and then protected on the back by a durable glass-like resin to create a hard lustrous finish. Comes with a leather cord and is finished with a silver lobster claw clasp. Dimensions: approximately 16" long.
