Lab Grown Diamond Princess Cut Cathedral Solitaire Ring 18K Yellow Gold 1.00ct

The Stone(s)

The primary focal point is a single, certified 1.00 carat princess-cut lab grown diamond. Positioned as a prominent solitaire, the diamond exhibits a crisp geometric step-and-brilliant faceting pattern that maximizes light return while retaining clean internal crystalline structures. This stone belongs to our standard eye-clean stock tier, featuring an F color grade (colorless) and VS1 clarity profile. Every center diamond undergoes independent gemological evaluation, featuring an IGI jewelry certification report number laser-inscribed directly on the girdle for verification.

A single structural accent diamond is deep-set within the circular bezel under-gallery profile. This hidden gem acts as a mechanical anchor for the elevated setting while providing an intricate, multi-angle design detail.

The Setting

Engineered for secure, high-clearance light transmission, the setting features a four-prong chevron design. Four white gold V-shaped claws encase the sharp, vulnerable corners of the princess-cut diamond, distributing structural tension to prevent chipping while exposing the maximum surface area to ambient light. The setting is elevated into an open architectural cathedral profile. This open under-gallery structure raises the pavilion of the diamond above the finger line, optimizing the refractive light paths through the facets. The two-tone integration utilizes white metal prongs to eliminate warm color reflection through the diamond body, maintaining its pure colorless appearance.

Metals and Finish

The default configuration is constructed in 18K yellow gold (750 purity code), providing a warm, classic hue that creates an intentional contrast against the white gold stone setting. The band is rendered as a solid, slightly tapered square-edged comfort-fit shank with a default high-polish finish. For active lifestyles or specialized preferences, the design can be ordered across our five-tier metal catalog:

• 950 Platinum: 95% pure platinum, providing maximum prong security and a hypoallergenic, tarnish-free composition.
• 18K Gold (750): Premium gold alloy balancing rich color saturation with structural integrity.
• 14K Gold (585): Our default balance of gold content and everyday tensile durability.
• 10K Gold (417): High-hardness gold alloy offering maximum scratch resistance.
• 925 Sterling Silver: Lightweight, reflective precious metal finished with anti-tarnish plating for casual wear.

Alternative finishes including Satin/Brushed, Matte, Hammered, or alternative two-tone distributions are available upon confirmation.
