More Info
This beautiful Old European Cut (OEC) lab diamond brings back the classic look of antique diamonds, made perfectly to fit into today's modern jewelry styles. Each stone showcases the signature OEC round cut appearance, featuring larger hand-cut style facets, a visible open culet, and broad reflections that create a soft vintage glow rather than the sharp sparkle seen in modern round brilliants. Available in convenient parcel quantities, these loose old European cut diamonds are ideal for restoring antique jewelry, crafting custom engagement rings, vintage inspired wedding bands, halo settings, earrings, pendants, and fine jewelry projects that require consistent matching stones.
Manufactured as premium lab grown OEC diamonds, these stones offer the same physical, chemical, and optical properties as mined diamonds, including exceptional 10/10 Mohs hardness. Graded EF color and VS clarity, they deliver bright white color, eye-clean appearance, and excellent transparency while maintaining the romantic charm associated with vintage round cut lab grown diamonds. The traditional faceting pattern emphasises depth, fire, and larger flashes of light, making these OEC diamond parcels a preferred choice for jewelers and collectors seeking authentic old cut aesthetics in smaller millimeter sizes.
Whether purchased as a pack of 5, 10, 15, or 20 diamonds, these traditional old European cut loose diamonds provide flexibility for matching side stones, eternity bands, cluster rings, and bespoke jewelry creations. Every order includes an Ouros branded authenticate certificate (IGI) and a diamond tester verification video before shipment for complete confidence in authenticity. With fast preparation, customisation support, and the ability to incorporate these stones into rings, necklaces, bracelets, or earrings, this collection offers an accessible way to bring the beauty of antique inspired Old European Cut lab grown diamonds into contemporary jewelry designs while preserving the vintage appeal of historic diamond cutting traditions.
