The Fancy Color Sapphire Collection
Featuring three distinctive rings, each centered around a rare, hand-selected sapphire and paired with carefully chosen diamonds and precious metals.
Every ring was designed in response to the individual character of its center stone, with each detail—from the cut of the diamond accents to the tone of the metal—selected to enhance and complement the beauty of these natural sapphires.
The result is a refined collection of sapphire rings that feels both cohesive and entirely singular—an expressive showcase of T. Foster & Co. original design.
The Teal Sapphire & Diamond Halo Ring
This stunning ring showcases a 2.05‑carat natural teal sapphire, masterfully faceted in a modified asscher cut to intensify its deep, shifting teal tones that subtly change as the light moves. The center stone is beautifully framed by ten round brilliant‑cut diamonds and two pear‑shaped diamonds, totaling 0.81 carats of sparkling accent stones. Set in an elegant silhouette on an 18K yellow gold band, the design balances modern sophistication with timeless warmth—perfect as a distinctive engagement ring or an eye‑catching right‑hand piece.
The Ocean-Blue Sapphire & Diamond Ring
This extraordinary ring showcases a 4.00-carat square-cut ocean-blue sapphire at its center. The sapphire’s natural teal-blue hue is rare and highly prized, typically found among the finest material from Madagascar and Sri Lanka. On each side of the sapphire are two round brilliant-cut diamonds and one pear-shaped diamond, combining for a total diamond weight of 1.27 carats. The entire composition is set in lustrous platinum, which beautifully enhances the sapphire’s cool, oceanic tones. Handcrafted and one-of-a-kind, this ring is a wearable work of art—perfect for anniversaries, milestone celebrations, or any moment when you want to elevate your elegance and sparkle.
The Asscher-Cut Teal Sapphire & Diamond Ring
This ring is a celebration of jewel tones, centered on a 2.51‑carat natural teal sapphire. The asscher-cut’s distinctive faceting creates a “hall of mirrors” effect that bathes the stone in shifting blue‑green flashes—revealing new depth and nuance as light and angle change. Flanking the sapphire are perfectly matched trapezoid and tapered‑baguette diamonds, totaling 0.67 carats, which add crisp brilliance without competing with the sapphire’s color.
The diamonds and sapphire are set in platinum to form a seamless, luminous head, while the band is crafted in warm 18k yellow gold to enhance the sapphire’s striking teal. The result is a timeless silhouette with a modern edge—equally stunning as a bold cocktail ring or a one‑of‑a‑kind engagement ring for someone who loves color and refined design.
