Radiant Moissanite Lab Diamond
Radiant Moissanite Lab Diamond
Full description & conditions
Experience the exceptional brilliance of our premium radiant-cut lab grown diamonds, expertly created using advanced CVD and HPHT technology for outstanding fire, clarity, and durability. Available in 1ct, 1.5ct, 2ct, 2.5ct, 3ct, and 5ct sizes, these loose diamonds showcase the radiant cut's signature combination of crisp faceting and remarkable sparkle. Designed to deliver the elegance of an emerald shape with the brilliance of a round diamond, radiant-cut diamonds offer a striking balance of sophistication and fire. Every stone is carefully selected for its beauty and quality, making it ideal for custom engagement rings, fine jewellery, pendants, earrings, and bespoke luxury creations. Each diamond is accompanied by a GIA certificate, providing complete confidence in its authenticity and grading.
Our lab grown diamonds are available in premium D and E colour grades, placing them among the most desirable colourless diamonds available. Clarity options include VVS1, VVS2, and VS1, allowing you to select the perfect balance of rarity and value. VVS1 and VVS2 diamonds contain extremely slight inclusions that are exceptionally difficult to detect, even under magnification, while VS1 diamonds remain beautifully eye-clean with only minor inclusions visible under close examination. Before delivery, a detailed video of your selected diamond will be provided for approval, giving you the opportunity to review the stone's brilliance, proportions, and overall appearance, or request an alternative option should you prefer another diamond.

Looks great, just running a tad big for the ordered size. But since i have fluctuating weight, it might also be on me.
