Bespoke Piece · Made to order

A fancy vivid green marquise lab grown diamond, 2.5 or 3 carats of VVS clarity, held in six fine prongs above a crown of floral diamond clusters — on an interlaced vintage band edged in milgrain. From above, the deep forest-green marquise reads clean and elongated, with a glint of white diamonds peeking around its edge. Turn the ring and the hidden halo appears: a ring of flower-shaped clusters of round colorless diamonds wrapping the gallery, each framed in hand-applied milgrain. The band twists in an open, rope-like weave, punctuated by bezel-set marquise diamonds in diamond-shaped frames and pairs of tiny round diamonds.

About Fancy Green Lab Grown Diamonds

Lab grown diamonds are real diamonds — chemically, optically, and physically identical to mined diamonds. The only meaningful difference is that they are grown in weeks rather than formed over billions of years.

“Fancy Vivid” is the most saturated colour grade a coloured diamond can receive. The green comes from the crystal itself, is locked into the stone, and will never fade. Natural green diamonds of this size and saturation are among the rarest gems on earth; lab grown makes the same colour attainable, with a transparent origin and no mining footprint.
