French GIA 2.31 carat no heat sapphire diamond platinum ring

This magnificent French Mid Century ring showcases a rare and naturally vibrant 2.31-carat no-heat violetish blue sapphire, certified by GIA and sourced from Madagascar. The sapphire’s rich, shifting tones—moving between royal blue and hints of velvety violet—create a mesmerizing depth of color that only untreated stones can achieve. Its oval cut enhances this natural beauty, allowing light to glide across the gem with a luminous, almost ethereal elegance.

Flanking the sapphire are two beautifully matched baguette cut diamonds totaling approximately 0.50 carat. Their refined G color and crisp VS clarity introduce a sleek, brilliant contrast, framing the center stone with the sophistication and geometry characteristic of French design in the 1950s. The diamonds’ elongated shape enhances the ring’s graceful silhouette, drawing the eye outward while maintaining perfect balance and harmony.

Crafted in platinum, the ring carries the strength, cool sheen, and timeless luxury expected from French mid-century jewelry. The French dog hallmark and purity mark confirm its Parisian origin and add distinguished authenticity, underscoring the exceptional craftsmanship behind the piece.

Elegant, rare, and beautifully preserved, this ring is a true collector’s treasure—an extraordinary blend of natural sapphire beauty, architectural diamond accents, and refined French artistry.
