0.70 ctw Lab Grown Diamond Round Signet Men’s Ring 14K Gold | Primira Luxury

The Stone(s)

The architectural center of this signet ring is an eye-clean, 0.50-carat round brilliant lab grown diamond. Graded within the premium EF colorless spectrum and VS clarity tier, the center stone exhibits high-dispersion fire and optimal light refraction. Accenting the broad shoulders of the band are twenty calibrated round brilliant lab grown diamonds totaling 0.20 carats (0.70 ctw total across all twenty-one stones). Every diamond selected is guaranteed to be free of visible inclusions, adhering to our strict workshop standard that excludes any stones graded SI2 or below. For verified authenticity, third-party certification is available on request, featuring an independent evaluation of the 4Cs and a laser-inscribed report number on the stone’s girdle verifiable via official laboratory registries.

The Setting

Engineered for structural security and everyday resilience, the setting mechanics employ a hybrid protective architecture. Four low-profile, rhodium-tipped shared prongs grip the center stone’s girdle, suspending it securely inside a recessed, tiered pyramidal square frame. This stepped golden platform visually expands the geometric silhouette of the round diamond, turning a traditional solitaire into a commanding contemporary signet. The twenty shoulder accents are sub-surface channel-set in two linear rows. By embedding the pavé rows within deep, recessed lateral channels, the gold borders shield the accent diamonds from lateral impacts and abrasive contact, ensuring a snag-free profile suitable for an active lifestyle.

Metals and Finish

This piece is built by default in solid 14K gold (585 purity code), delivering the ideal engineering balance of pure gold content and structural hardness required for a wide, high-contact men’s band. The flat-profile shank features a high-polished mirror finish across its wide yellow gold flanks, creating a stark visual contrast against the white, rhodium-plated central prong setting that preserves the colorless purity of the diamond. For alternative styling, the ring can be cast in 10K gold (417) for maximum scratch resistance, 18K gold (750) for enhanced alloy richness, or premium 950 Platinum—the densest metal option providing the ultimate level of lifelong prong security.

Customisation and Origin

Every ring is built entirely to order, allowing for complete optimization of specifications to fit the wearer’s personal style and daily habits. The flat, tapered inner band is engineered with a solid under-gallery architecture for weighted balance, and can be customized with a smooth satin or brushed finish to dial down the high-polish shine for a more understated look.
