Blue is the rarest color a diamond comes in, and Vivid is the deepest it gets. This 3.84ct oval grades Fancy Vivid Blue, the very top of the color-intensity scale, above Intense, above Deep. That means a saturated, electric blue that holds across the entire stone, the kind of color most people have only seen behind museum glass.

The oval shape is doing real work here. Its broad facets and elongated outline give the blue room to pool and glow, and the length spreads the color across the finger so it reads big and bold. Graded VS clarity, the stone stays clean to the eye while the color carries the whole look.

The vintage-style two-tone setting is built to defer to the stone. White gold rings the blue so nothing warms or dulls it, while yellow gold runs through the band for contrast. Mixing white and yellow gold is a vintage design tradition, so the metal frames the color with an antique, estate-piece character rather than competing with it.

A note 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 itself, grown in, not a coating or treatment, so it never fades. Optically and chemically it behaves exactly like any mined diamond.

A Vivid Blue at this size is scarce even in lab grown, so this piece is likely one of a kind.

FAQ
Is this a real blue diamond?

Yes. It's a lab grown diamond with blue body color from the growth process (not coated or treated). Chemically and optically identical to a mined diamond.

What does Fancy Vivid Blue mean?

Vivid is the highest grade on the fancy-color intensity scale: the deepest, purest saturation, above Intense and Deep. It's the most prized level of color.

Will the blue fade over time?

No. The color is the body color of the diamond crystal, not a surface treatment, so it's permanent.

Is this the only one?

A Vivid Blue at this size is scarce; this piece is likely one of a kind.

Does it come with a certificate?

Lab grown diamonds 1 carat and above are IGI-certified and verifiable online.
