Lab Grown Diamond 1.03ct Radiant Cut Halo Ring 14K Gold

The Stone(s)

The architectural center of this design is a 1.03 carat radiant-cut lab grown diamond measuring 7.02 x 4.87 x 3.17 mm. Combining the elegant silhouette of a step-cut emerald shape with the brilliant-cut facet pattern patterns of a round stone, this vivid yellow diamond exhibits intense light refraction and eye-clean SI1 clarity. Surrounding the center stone is a seamless single halo consisting of 20 round brilliant lab grown diamonds. An additional 30 round brilliant lab grown diamonds are set along the shoulders of the shank. These 50 accent stones total 0.47 carats and are graded at colorless EF color and eye-clean VS clarity. Every center stone choice is backed by verifiable laboratory grading, with loose lab grown diamonds accompanied by an IGI certification report detailing laser-inscribed girdle registries.

The Setting

Engineered for both optical performance and structural security, the center stone is mounted in a dual-metal open gallery. Four low-profile yellow gold prongs grip the corners of the radiant stone. By matching the prong alloy to the yellow diamond, the metal reflects inward to saturate and deepen the canary hue rather than creating white metallic reflections. This yellow gold basket sits upon a solid 14K white gold platform. The single halo frame uses shared-prong micro-pavé settings to form a continuous border of light that visually expands the center stone’s footprint by approximately 0.50 carats. The open under-gallery architecture allows maximum light entry from beneath the girdle, driving optimal sparkle while remaining flush enough against the finger for daily wear without catching.

Metals and Finish

Constructed with a gross weight of 4.00 grams and a net metal weight of 3.70 grams, the ring is presented by default in 14K white gold (585 purity) with a flawless high-polish rhodium finish. For alternative active lifestyles or setting preferences, this design can be ordered across five distinct metal tiers:

• 950 Platinum: 95% pure platinum, hypoallergenic, maximum prong density.
• 18K Gold (750 purity): Rich golden hue, excellent structural integrity for multi-stone mountings.
• 14K Gold (585 purity): The default standard balancing pure gold content with daily durability.
• 10K Gold (417 purity): Maximum scratch resistance for highly active lifestyles.
• 925 Sterling Silver: Lightweight, anti-tarnish everyday fashion option.

Available tones include classic yellow gold, crisp white gold, and warm rose gold.
