An exceptional vintage convertible ruby and diamond necklace, crafted in 18K yellow gold and designed with remarkable scale, brilliance, and versatility.

This striking piece is set with a collection of vivid pear-shaped rubies totaling approximately 15.27 carats, including a dramatic detachable drop centerpiece featuring a 6.01-carat pear-shaped ruby. The remaining rubies are elegantly distributed throughout the necklace, creating a rhythmic and balanced design.

The rubies are framed by an extraordinary diamond setting, comprising approximately 27.45 carats of round brilliant diamonds and 2.90 carats of baguette-cut diamonds, arranged in intricate openwork floral and geometric motifs that enhance both light reflection and dimensionality.

Designed as a convertible jewel, the necklace may be worn in multiple ways:

As a full statement necklace with drop pendant
As a shorter collar without the drop
Potentially styled with detachable elements depending on configuration

The craftsmanship reflects the bold elegance of late 20th-century high jewelry, combining fluid articulation with substantial gold weight and exceptional stone presence.
