7.7-Carat Lab-Grown Oval Diamond Ring: E Color, VVS2 Clarity in 18K Gold
7.7-Carat Lab-Grown Oval Diamond Ring: E Color, VVS2 Clarity in 18K Gold
Core Gemstone & Quality Details
-
Main Stone: 7.7-carat lab-grown oval diamond (single-stone design to highlight its impressive presence)
-
Cut: Oval Brilliant Cut (rounded elongated silhouette with 58 precision facets, maximizing light reflection to create rich fire, while visually slimming and lengthening the finger)
-
Color: E Color (near-colorless top grade, ultra-bright and pure, free from obvious warm tones, perfectly complementing the oval cut’s luminous appearance)
-
Clarity: VVS2 Clarity (very very slightly included, completely eye-clean. Internal characteristics are extremely subtle and invisible even under close observation, ensuring flawless visual purity for the large-carat stone)
-
Overall Quality: Lab-grown (sustainable, conflict-free, chemically identical to natural diamonds; no artificial enhancement on color or clarity, retaining authentic premium texture)
-
Setting Material: 18K Gold (high-purity luminous luster, excellent ductility to securely hold the large-carat diamond. Its soft tone balances the oval cut’s elegance, creating a harmonious and luxurious style)
Design & Craftsmanship
-
Contoured Six-Prong Setting: 18K gold prongs are custom-shaped to fit the oval diamond’s curved edges, with reinforced prongs at the pointed ends and smooth prongs along the sides. This design firmly secures the 7.7-carat diamond while avoiding covering key facets, maximizing light penetration for enhanced brilliance.
-
Weight-Balanced Ring Band: To match the main stone’s weight, the band is appropriately reinforced and widened at the shoulders, tapering gently to the shank. Its ergonomic curve fits the finger’s natural arc, ensuring comfortable wear without slipping.
-
Meticulous Polishing Craftsmanship: All setting edges and the band’s inner wall are mirror-polished, preventing scratches on the skin. The junction between prongs and band is seamlessly connected, reflecting exquisite craftsmanship worthy of the high-grade diamond.
