4.00 Ct | Red | Clean Clarity | Cushion Cut | Three Stone | Lab Grown Ruby

Center: 3.50 Ct Cushion Ruby (10x8) | Accent Diamonds: 2 Trapezoid Lab Grown Diamonds = 0.50 Cts | Total: 4.00 Ct | Sizes 4–9

A 3.50 Ct cushion cut ruby in deep red sits center, flanked by two trapezoid lab grown diamonds that sharpen the geometry and let the ruby own the moment. The proportions are deliberate: the trapezoids step down cleanly from the center, adding brilliance without pulling focus.

Lab grown rubies and diamonds are real stones, not simulants, not cubic zirconia. Grown using the same physical and chemical conditions as their mined counterparts, then handset in our New York City studio in the Diamond District. Sold direct from the maker, so more of your investment goes into the ring.

A strong choice for an engagement ring, a milestone anniversary, or any occasion that warrants something built to last.
