Materials and Features:

• Chatoyant Moonglow Lucite Material: A textbook example of post-war injection-molded acrylic resin technology. These 13mm round beads are chemically infused with microscopic pearlized reflective particles, creating a deep optical chatoyancy that appears to glow from within when exposed to shifting light angles.

• Hand-Knotted Silk-Blend Threading: The substantial 48.5g strand is meticulously tensioned on a thick cream-colored silk-blend cord, featuring individual safety knots hand-tied between every single bead to prevent surface friction and ensure a fluid drape.

• Stamped Coro Flower Backing Plate: The reverse of the focal clasp bead features Coro's proprietary five-petal scalloped brass stabilizer plate. This structural component is soldered directly to the square female box receptacle to isolate mechanical stresses and protect the soft Lucite housing from fracturing.

• Coiled Gimp Wire Terminations: The cord ends are structurally reinforced at the clasp rings using tightly compressed base-metal coil wire protectors, ensuring total physical permanence and preventing long-term structural fraying at the primary tension points.

Type: Concealed round box clasp with a thin brass slide-in tongue mechanism.

Age/Origin: Circa 1953 / Providence, Rhode Island, USA

Marks: Unmarked (Attributed to Coro based on proprietary five-petal scalloped backing plate architecture and 1950s factory assembly specifications)

Measurements:

• Weight: 48.5g

• Thickness: 13mm (Uniform bead diameter across the entire strand)

• Dimensions: Approx. 17” total operational length from end to end

Condition: Excellent Vintage Condition. All Lucite beads retain their original high-gloss luster with zero internal clouding, scratching, or structural flea bites. The original silk-blend cord remains structurally tight with no stretching, and the brass box clasp locks securely with a firm mechanical snap.
