Complete Description
Three step cuts in a row: an emerald-cut lab-grown diamond at the center, flanked by two smaller emerald-cut side stones that repeat its clean, rectangular lines. Using the same cut across all three stones makes the ring read as one continuous, architectural statement — long parallel facets that flash light and shadow in the "hall of mirrors" effect emerald cuts are known for. It's a bold, Art Deco-inspired take on the three-stone ring, all crisp geometry and no fuss.
Because the emerald cut has a large open table with fewer facets to hide behind, color and clarity show more than in a brilliant cut — which is why the DEF color, VS clarity diamonds matter here: they read icy white and eye-clean, exactly what this cut calls for.
Available from 3 to 30 carats in 18kt white, yellow, or rose gold, and crafted to your ring size.
Styling Tip
An all-emerald-cut three-stone pairs beautifully with a plain or emerald-cut eternity band for a fully step-cut look. White gold keeps it crisp and modern; yellow gold adds warmth; rose gold softens it.
Choose your carat and gold tone, and we'll craft it to your size.

Yes. Lab-grown diamonds have the same physical, chemical, and optical properties as mined diamonds — the same hardness and brilliance — and are graded by the same independent laboratories. The difference is that they're grown in a controlled setting rather than formed in the earth.
