Lab Grown Diamond Round Brilliant Cathedral Solitaire Ring 14K Gold 0.70ct

1. The Stone(s)

The primary focal point of this cathedral design is a single, independently graded 0.70-carat round brilliant lab grown diamond. Positioned as the isolated center stone, its optical geometry features an Excellent cut grade, balancing standard facet angles to maximize internal light return and eliminate light leakage. This laboratory-grown diamond carries an official IGI certification, featuring a laser-inscribed report number on the stone’s girdle that is instantly verifiable online at igi.org. Graded within the colorless D-E-F spectrum (specifically E-F) and maintaining a VS eye-clean clarity tier, the stone contains no visible inclusions to the naked eye. In accordance with Indian BIS IS 19469:2025 mandates and global compliance, this stone possesses identical physical, chemical, and optical properties to a mined diamond.

2. The Setting

The structural framework of this solitaire utilizes a traditional 4-prong setting engineered for maximum light exposure along the stone’s pavilion and crown. The 4-prong white metal head isolates the colorless diamond from the warm hue of the shank, preventing any metal color transfer from tinting the stone. This claw array is elevated by a classic cathedral profile, where the shoulders of the band arch upward to meet the gallery. Beneath the center setting, the open gallery clearance incorporates dual geometric circular side apertures. This specialized bridge profile allows light to penetrate the diamond from multiple side angles while ensuring the low-profile setting protects the stone’s girdle from lateral impacts.

3. Metals and Finish

Constructed with a tapered, solid shank, the ring is presented in 14K Gold (585 purity code) with a default high-polish finish. This alloy composition contains 58.5% pure gold, providing a highly durable structural framework suited for a daily-wear engagement ring. While shown in a distinctive two-tone layout—combining yellow gold with a white gold head—the band is fully orderable across alternative metal tiers to suit specific active lifestyles or budget parameters. Clients can select 950 Platinum for dense prong security, 18K Gold (750) for a richer metallic hue, or 10K Gold (417) for maximum scratch resistance, available in yellow, rose, or rhodium-plated white gold tones.
