Product Description
Inspired by traditional European diamond cutting, this traditional old European round cut lab grown diamond features a high crown, open culet, and larger hand cut style facets that create broad flashes of light instead of the fast sparkle seen in modern round brilliant diamonds. Available from 0.50 CT to 5.00 CT, it can be selected in EF/VVS and EF/VS for a bright white, colorless appearance, GH/VVS and GH/VS for a soft, near-colorless look, or J–Z/VS for buyers who prefer the naturally warmer tone often associated with antique Old European Cut diamonds.
With a 1.00 round ratio and 10/10 hardness, this loose lab grown diamond is suitable for engagement rings, heirloom-inspired jewelry, and custom designs. Diamonds of 1.00 ct and above include IGI certification, while every stone is carefully cut to preserve the traditional Old European faceting that collectors and vintage jewelry enthusiasts appreciate.
Whether selected as a loose diamond or paired with a custom engagement ring design, this Old European Cut diamond is an excellent choice for buyers who appreciate chunky facets, an open culet, and vintage inspired design. Its timeless round shape works beautifully in solitaire, bezel, halo, and Art Deco-inspired settings, making it a versatile center stone for custom jewelry creations.
