9.12-Carat Lab-Grown Santa Maria Aquamarine Ring: Oval Cut in 18K White Gold Setting

Core Gemstone & Quality Details

• Main Stone: 9.12-carat lab-grown Santa Maria Aquamarine (The core center stone is cultivated via hydrothermal technology, replicating the crystal structure and signature blue tone of natural Santa Maria Aquamarines. Lab-grown technology enables the stable combination of extra-large carat weight and high color grade.)
• Cut: Oval Brilliant Cut (elongated curved silhouette with smooth lines, 58 precision-cut facets that optimize light reflection, amplifying the aquamarine’s inherent transparency and vivid blue glow while visually lengthening the finger)
• Color: Santa Maria Blue (uniform high-saturation tone, the signature of top-tier Santa Maria Aquamarine, with subtle violet undertones and zero gray or yellow tints)
• Clarity: VS2 Clarity (very slightly included, with minimal needle-like inclusions invisible to the naked eye; only detectable under 10x magnification, ensuring the gem’s translucent purity)
• Accent Details: Lab-grown diamonds (symmetrically set on the ring shoulders and along the band’s edge, forming a delicate halo that highlights the aquamarine’s clear blue hue)
• Accent Stone Quality: D-F Color (colorless to near-colorless), VS1 Clarity (eye-clean), Excellent Cut (optimal light performance to complement the aquamarine’s soft blue tone without overwhelming it)
• Overall Quality: The main stone is lab-grown (replicating the color grade and clarity characteristics of Santa Maria Aquamarines, free from origin mining restrictions, combining environmental attributes and stable quality; no heat treatment or dyeing, maintaining natural texture); accent stones are lab-grown diamonds (conflict-free, environmentally friendly, with quality parameters matching the high-end positioning of the main stone)
• Setting Material: 18K White Gold (polished finish, 75% gold content ensuring superior ductility and scratch resistance; cool metallic luster creates a perfect complement, intensifying the Santa Maria Aquamarine’s blue saturation)

Design & Craftsmanship

• Oval-Tailored Reinforced Claw Setting: 18K white gold prongs are custom-machined for the oval silhouette—5 reinforced prongs (2 at the tapered ends, 3 along the curved sides) securely clasp the 9.12-carat aquamarine, with minimal facet coverage. Prong surfaces are mirror-polished, with micro-engraved textures to ensure long-term stability without compromising aesthetics.
• Structured Solid Band: The 18K white gold band maintains a 2.5mm uniform width from setting to shank, with a high-gloss polished surface that mirrors the aquamarine’s radiant glow. The minimalist structure ensures the large Santa Maria gem remains the visual core, adhering to high-jewelry design principles.
• Load-Bearing Ergonomic Design: The band junction is reinforced with a hidden arc structure to support the weight of the 9.12-carat main stone. The inner wall is precision-machined into a semi-circular arc, fitting the physiological curve of the finger and ensuring comfort during extended wear.
