The Solitaire Pendant: Lab-Grown Diamond 4-Prong Perfection
A singular point of light, refined for the modern silhouette. Our 4-Prong Solitaire Pendant is the ultimate expression of Don Key’s philosophy: stripping away the noise to focus on architectural strength and uncompromising brilliance.
Crafted for those who value understated luxury, this pendant features a hand-selected lab-grown diamond that mirrors the physical and optical properties of earth-mined stones—offering a cleaner, more conscious path to high-end jewelry.
Design Details

The Setting: A minimalist 4-prong basket designed to be nearly invisible. This open-air architecture allows maximum light to enter the diamond, amplifying its natural fire and scintillation from every angle.
-
Refined Integration: The pendant features a sleek, integrated bail that ensures the piece sits perfectly against the skin, maintaining a fluid and balanced profile throughout the day.
-
Conscious Craftsmanship: Each stone is a sustainably sourced, lab-grown round brilliant diamond, selected for its exceptional G-H color and SI1-SI2 clarity.
-
Premium Materials: Forged in 14K Solid Gold (Yellow, White, or Rose options), providing a durable, high-polish finish that resists the elements and stands the test of time.

Why Lab-Grown
Identical brilliance.
Better story.
Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds — the only difference is how they're created. Grown above ground using advanced technology, they produce the same fire, scintillation, and brilliance at a fraction of the environmental cost.
Every stone we use comes with an certificate — the same independent grading standard used for mined diamonds. You know exactly what you're buying.
