18K Sapphire Diamond Flower French Brooch 1970

Created circa 1970, this striking brooch embodies the expressive and sculptural aesthetic that defined high jewelry of the late twentieth century. Designed as a stylized flower with elongated, flowing elements, the piece combines vibrant gemstones, richly textured gold, and brilliant diamonds in a dynamic composition that feels both organic and architectural.

At its center sits a vivid oval sapphire weighing 2.69 carats, accompanied by a Gübelin certificate confirming Madagascar origin and no heat treatment. The sapphire’s deep, saturated blue anchors the design and provides a beautiful contrast against the surrounding diamonds and warm gold surfaces. Around the central stone, the petals are pavé-set with white diamonds, mounted in platinum, enhancing their brilliance and providing a cool-toned frame for the vibrant sapphire.

Extending below the flower are graceful, elongated tendrils sculpted in textured 18k yellow gold, each articulated with a natural sense of movement. Several of these elements are set with blue sapphires, echoing the color of the central stone and creating visual rhythm throughout the composition. The textured gold surfaces catch the light subtly, while the gemstones introduce sparkle and depth.

Measuring 3 inches in length and approximately 1 inch at its widest point, the brooch has an elegant, elongated silhouette that lends itself beautifully to wear on a lapel, dress, or evening jacket. The balance between structure and fluidity reflects the bold design language that emerged during the 1970s, when jewelers embraced sculptural forms and strong gemstone contrasts.

With its certified 2.69 carat unheated sapphire, carefully set diamonds, and refined craftsmanship in 18k gold and platinum, this brooch stands as a compelling example of the era’s artistic jewelry design—both expressive and timeless.
