Blue Radiant Cut Lab Grown Diamond Ring in 14K Two-Tone Gold

Blue is the color of calm and depth, and on a diamond it reads as confidence. This one is graded Fancy Intense Blue, which sits high on the color scale: a clear, saturated blue with no grey wash, the kind of stone that holds its color across the whole table rather than fading at the edges.

The radiant cut is the right frame for it. Its trimmed corners and brilliant faceting bounce light through the body of the stone, so the blue reads vivid and alive instead of flat. At 5.22ct with VVS2 clarity, this is a large, exceptionally clean center: a true statement piece, not an everyday solitaire.

We set it in vintage-style two-tone 14K white and yellow gold: white metal close to the stone keeps the blue cool and true, with warm gold for contrast on the band. Mixing white and yellow gold this way is a vintage design tradition, an antique-style frame for a stone that already commands attention.

A word on the color: this is a lab grown diamond, created in a controlled facility rather than mined. The blue is the body color of the crystal, grown in, not coated or treated, so it never fades. Optically and chemically it behaves exactly like any mined diamond.

A stone this size and saturation is scarce even in lab grown, so this piece is likely one of a kind.
