Diamond Marquise Hidden Gem Charm

Product Description

The Marquise Diamond Hidden Gem captures the romance of an antique jewel with the luminous brilliance of a modern diamond.

Part of our evocative Arcana Collection, this 14K gold charm features a lab-grown marquise-cut diamond embraced by an intricately sculpted, vintage-inspired setting. The diamond's elegant, elongated silhouette and pointed ends create a captivating contrast against the softly irregular gold surround, while delicate prongs and ornamental details lend the piece an almost archaeological beauty.

Inspired by the allure of forgotten treasures, the Hidden Gem feels like something discovered in a velvet-lined jewelry box, waiting for its next chapter.

Wear it alone for an understated flash of brilliance or layer it among personalized Reliquary charms, engraved medallions, and other collected treasures. A little decadence, a little mystery, and a beautiful reminder that the most extraordinary things are often found in unexpected places.

Design Inspiration | The Arcana Collection

From Zoë, Founder & Designer

"I've always been captivated by the romance of antique jewelry—especially those beautifully unusual pieces that feel as though they have a secret history.

The Hidden Gem designs were inspired by that sense of discovery. I wanted to create little diamond treasures with the character of something unearthed rather than newly made. Their organic gold settings feel almost like miniature artifacts, with the brilliance of the diamonds providing a beautiful contrast.

The marquise shape is especially romantic to me. Its elongated silhouette has an almost regal quality, but the irregular gold setting gives it a relaxed, slightly unconventional spirit.

I love the idea of tucking one of these little gems among personalized charms. A bit of unexpected brilliance in a necklace filled with meaning."

— Zoë

The Meaning Behind the Marquise Hidden Gem

A Symbol of Individuality & Enduring Beauty

The marquise diamond has a storied history, traditionally associated with elegance, romance, and aristocratic jewelry. Its distinctive elongated shape is often linked to the 18th-century French court and the legendary smile of the Marquise de Pompadour.

Beyond its romantic origins, the marquise silhouette offers a beautiful expression of individuality—an unconventional diamond shape for those drawn to jewelry with character.

Diamonds have long symbolized strength, devotion, and enduring connection. Within the Arcana Collection, the Hidden Gem becomes a personal talisman, celebrating the beauty of what makes each of us extraordinary.

A treasure to mark a milestone, honor a personal triumph, or simply celebrate the pleasure of something beautiful.

How to Style Your Marquise Diamond Hidden Gem

The elongated silhouette of the Marquise Diamond Hidden Gem makes it a natural companion to the organic shapes of the Reliquary charms.

Wear it alone on a delicate gold chain for a quietly luxurious statement, or incorporate it into a layered charm necklace filled with personal meaning.

For a more eclectic, California-cool composition, pair it with round and oval engraved medallions, a slender rectangle charm, or a luminous pearl accent. Its sculptural gold frame and brilliant diamond bring an unexpected contrast to vintage-inspired gold chains and personalized keepsakes.
