Extremely Rare Original Lea Stein Paris Necklace

Extremely Rare Original Lea Stein Paris Necklace with striated rear blue disk, all inset with many different variations of fine white details of roses, flowers, and leaves, to both side of domed surfaces. All in perfect condition, including original Brass barrel screw clasp, still in excellent working order. The last two disks adjacent to clasp, are each impressed with Hallmark, Lea Stein Paris. Lea Stein pieces are more commonly with Brooches and the occasional Bangle, but a necklace is very hard to find. The very few necklaces seen are usually a simple disc with an edge flask, or circle of colour. First one ever seen with many different varied details and individual designs.  Dimensions approx.: overall length 40.5cm long; discs 1.8cm dia. x 0.3cm thick max. Lea Stein, Paris. France
