A continuous line of vivid turquoise cabochons—twenty-three in total, graduating from 10mm to 6mm—creates a bold yet harmonious rhythm around the neck. Each stone is encircled by deep blue sapphires, forming delicate halo settings that enhance the turquoise’s natural greenish-blue color. The stones display organic inclusions and subtle variations, giving the piece a sense of authenticity and individuality.

At the center, the necklace blossoms into an ornate focal point. Sapphire and diamond florets introduce a soft, floral elegance, leading the eye downward to a pear-shaped turquoise drop that moves gently with the wearer. Three round brilliant-cut diamonds, totaling approximately 0.85 carats, add a refined sparkle, contrasting beautifully with the rich saturation of the surrounding gemstones.


Handcrafted and thoughtfully designed, the necklace is finished with a concealed clasp and safety, preserving the seamless flow of its silhouette. Dating to circa 1935 and in good condition, this piece reflects a transitional moment in design—where structure meets softness—resulting in a necklace that is both timeless and distinctly expressive.
