Minimalist East-West Geometry Meets Italian Luxury

Embrace a masterclass in understated elegance with this Emerald Cut Solitaire Necklace from Roberto Coin’s iconic Diamonds by the Inch Collection. Celebrated for introducing fluid, everyday wearable luxury into the fine jewelry landscape, this piece updates a classic solitaire design with striking architectural modernism. The necklace centers on a single, hand-selected 0.17 carat emerald-cut diamond, renowned for its long, step-cut rectangular facets that deliver a dramatic, hall-of-mirrors flash of brilliance.

The diamond is oriented in a contemporary East-West horizontal setting, completely encased within a sleek, protective single bezel frame. This ultra-smooth bezel maximizes the diamond's crisp geometric silhouette while keeping it perfectly comfortable against the collarbone. Set on a delicate, high-polish 17-inch cable chain, this necklace radiates classic femininity when worn on its own, yet acts as the perfect structural anchor when layered into a texturized, luxury necklace stack.

While in stock in 18k yellow gold for a warm, classic aesthetic, this versatile design is available to order in your choice of 18k Rose Gold, 18k White Gold, 18k Yellow Gold, or a mixed two-tone 18k Yellow/White Gold finish to match your personal signature style.

The Hidden Ruby: A Token of Prosperity

True to the legendary legacy of the Venetian designer, this Diamonds by the Inch necklace features Roberto Coin's most romantic signature: a small, vibrant red ruby cast flush against the reverse side of the bezel setting. Intentionally positioned to maintain direct, intimate contact with the wearer's skin, this secret gem serves as a personal message of health, peace, and eternal good fortune from the artisan himself.
