The Stone
The center stone is a 1.50-carat pillow-shaped square cushion-cut laboratory-grown diamond. It features an Excellent cut grade with a dense brilliant faceting array optimized for high light-return parameters. Graded at an F color tier (completely colorless to the naked eye) and VS1 clarity, the stone is entirely eye-clean and free of visible inclusions. The lab grown diamond has the same optical, physical, and chemical properties as a mined diamond. It features an independently graded, laser-inscribed report number on the girdle, fully verifiable at igi.org to ensure objective specification confidence.
The Setting
The structural architecture uses a low-profile, split double-claw 4-prong configuration. Four dual-pronged corner claws anchor the cushion diamond’s corners along the girdle line, protecting the stone against lateral impact while minimizing metal coverage over the crown facets. The base of the setting integrates an open-access structural wire gallery. This open under-gallery maximizes pavilion exposure, allowing unobstructed light entry from all side angles to drive internal reflection without raising the setting depth away from the hand.
Metals and Finish
This piece is engineered by default in 14K yellow gold (585 purity purity code), delivering an optimal metallurgical balance between pure gold content and structural durability for daily wear. The shank is shaped into a slim, solid rounded band finished to a mirror-grade High Polish. For alternative wear requirements or skin sensitivities, this setting is customizable in 950 Platinum (95% pure, dense, hypoallergenic prong security), 18K Gold (750 purity, rich hue), or 10K Gold (417 purity, maximum scratch resistance) across yellow, white, and rose tones.
Customisation and Origin
Every ring is made-to-order and fully customizable. Standard center-stone carat weights range from 0.25ct up to 3.00ct+, alongside adjustable metal tiers, band widths, and quarter or half-ring sizes. The low-profile setting depth is engineered specifically so the band rests flush against standard wedding bands, removing the need for a curved contour band.
