Description
  • 3.48ct old mine cut center
  • Fancy Brownish Yellow
  • VS2 clarity lab grown diamond
  • Warm champagne color
  • saturated and even: the body color of the crystal

  • Chemically and optically identical to a mined diamond
  • IGI-certified lab grown diamond (1ct and above)
  • A rare antique-cut fancy-color stone with saturated champagne color

Champagne color and an old mine cut belong together. Both look like they were pulled from an estate jewelry box. This 3.48ct stone holds a Fancy Brownish Yellow, a warm golden-champagne tone, cut in the antique old mine style with its high crown, small table, and broad hand-shaped facets.

That cut is the right home for this color. An old mine cut glows under warm light rather than throwing rapid sparkle, and the big open facets let the champagne tone spread and warm instead of scattering into white flashes. Graded Fancy Brownish Yellow with VS2 clarity, it reads richly colored and clean to the eye.

The setting completes the period look. Solid 14K yellow gold (58.5% gold) is the metal these antique stones were traditionally worn in, and its warmth carries the champagne color right through the band, so the whole ring feels inherited rather than new.

A note on the color: this is a lab grown diamond, created in a controlled facility rather than mined. The champagne hue 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.

An antique-cut champagne stone at this size is scarce even in lab grown: a vintage look and fancy color you rarely see together.
