An exceptional mid-Victorian ouroboros snake necklace with a richly colored purplish garnet head and rose cut diamond eyes. Perfectly detailed and of the highest quality construction. Wears just off the neck, with the snake head at the back, or to the side. Most likely English in origin, but the tongue bears Austro-Hungarian import marks, so at some point in the 19th century it was for sale there. In nearly unworn condition.
