Marquise Teal Sapphire Ring with Channel-Set Baguette Diamonds in 14k White Gold

There is something undeniably romantic about a marquise — that elongated, pointed silhouette born of legend, said to have been commissioned by Louis XV to mirror the lips of his beloved. Here at Petra Star, we've paired that timeless shape with one of the most quietly extraordinary gemstones in the modern collector's lexicon: a teal blue Australian sapphire, ethically mined and cut at its source.

At 0.65 carats, this marquise sapphire occupies a sweet spot of wearability and presence. Its teal blue hue — that mesmerizing confluence of deep sea blue and verdant green — shifts with every movement, every light source, making it a stone that rewards the wearer who pays attention. Set in a classic illusion mounting, the setting amplifies the stone's apparent size and draws the eye inward toward the color, creating a focal point of quiet drama on the hand.

The mid-century, circa 1940, 14k white gold mounting is both the perfect frame and a nod to the enduring elegance of mid-century design. Straight baguette diamonds flank the center stone in a clean channel setting — precise, architectural, and brilliantly white at G/H color — providing contrast that makes the teal sapphire sing. 

Ethically sourced, thoughtfully set, and designed to be worn for a lifetime — this is Petra Star at its most intentional.
