Ultra Rare Vintage Schreiner Keystone Ruffle Convertible Pendant Necklace and Brooch

Elevate your collection with an absolute masterpiece of mid-century costume jewelry craftsmanship. This breathtaking, verified **Schreiner New York** convertible set features the legendary "keystone ruffle" design, flawlessly rendered in brilliant, ice-clear crystal rhinestones. Exceptionally rare and highly coveted by collectors, this statement piece embodies the bold, dimensional architecture that defined Henry Schreiner's couture creations in the 1950s. 

True to Schreiner's genius for engineering, this is a fully convertible 2-in-1 treasure. The dramatic, tiered ruffle centerpiece features a secure pin-back mechanism on the reverse, allowing it to unhook seamlessly from the matching crystal collar. Wear it as a show-stopping statement necklace, or detach the pendant to wear as a standalone signature brooch on a lapel, scarf, or gown. 

**Design Highlights & Schreiner Construction Verification:** 

* **The Keystone Ruffle:** The centerpiece is built using Schreiner's iconic multi-tiered, architectural style. Alternating rows of elongated keystone/baguette crystals radiate outward like crisp fabric ruffles, anchored by a massive brilliant-cut chaton center stone and teardrop-cut pear rhinestones.
* **The Collar:** A matching, beautifully articulated chain composed of alternating marquise and round chaton rhinestones, terminating in a classic extender chain and hook clasp.
* **Expert Craftsmanship:** Every single stone is meticulously hand-set in heavy, premium silver-tone rhodium plating with open-backed settings to maximize light refraction and fire.

**Condition:**
Excellent vintage condition. All rhinestones are present, bright, and full of intense sparkle. The silver-tone setting is crisp and clean with minimal aging. The pin mechanism and necklace attachment hooks function perfectly.

*Note: This piece features all the signature manufacturing traits of unsigned, verified Schreiner jewelry (such as the distinct crimping, stone usage, and structural design).*

Pendant measurements in photo but is approximately 24” including the extension. The brooch is approximately 3 1/2” square. An absolutely stunning and unique show-stopper.
