This ring is pure romance with a royal streak.
At its center is a 4.41 carat natural royal blue sapphire with the kind of rich, velvety color that makes sapphire lovers go weak at the knees. GIA notes the color appearance of this stone as “Royal Blue,” one of the most coveted color descriptions in the trade, and this beauty comes from Madagascar.
Now for the part that makes collectors truly swoon: this sapphire has not been heated. Most sapphires on the market are heat treated to improve color and clarity, so finding a fine natural sapphire with gorgeous royal blue color and no heat enhancements is a genuine rarity. It is that magical combination of beauty, scarcity, and desirability that gives this ring its special allure.
The sapphire is supported in platinum by four prongs and framed by a bold double halo of 20 round brilliant cut diamonds, totaling approximately 1.60 carats. The bright white diamonds wrap the center stone in a dazzling burst of light, while the platinum mounting, caged under gallery, split shoulders, and softly rounded shank give the ring a graceful and substantial presence on the hand.
It’s glamorous, elegant, and just dramatic enough — the kind of ring that doesn’t whisper across the room, it gets noticed.
