The Stone(s)
The focal point of this solitaire ring is a 1.50 carat Cushion cut lab grown diamond. This stone exhibits an elongated cushion modified brilliant faceting pattern, engineered to produce a distinct light-return cross-fire across the crown. Graded as an F color grade (colorless tier) and VS2 clarity, the diamond is entirely eye-clean with no inclusions visible to the naked eye. The diamond is independently evaluated under strict international laboratory metrics to confirm its Excellent cut grade, featuring a laser-inscribed report number on the girdle verifiable directly at the IGI registry.
The Setting
The setting architecture uses a low-profile, open wire basket configuration supported by four delicate pointed claws. This structural placement minimises the metal footprint on the corners of the cushion stone, allowing unobstructed light entry from the sides to drive internal reflection. The open gallery undercarriage is engineered to keep the stone’s table close to the finger while maintaining structural stability, ensuring the four prongs grip the stone’s girdle securely without shifting over years of wear.
Metals and Finish
This piece is built by default in 14K yellow gold (585 purity code), offering a balanced combination of gold content and everyday durability. The band features a seamless, slender plain shank that tapers slightly as it meets the crown, finished with a high-polish surface treatment. The ring can also be ordered across our five-tier metal framework, including 950 Platinum for ultimate prong security, 18K gold (750), 10K gold (417) for active lifestyles, and 925 Sterling Silver. Yellow gold settings naturally saturate the warm hues of the metal, providing a classic contrast to the colorless F grade center diamond.
Customisation and Origin
Every order follows a strict manufacturing path: after checkout on primiraluxury.com, our workshop team will confirm your exact specifications via WhatsApp and email within 24 hours before production begins. During this consultation, you can modify the stone carat (solitaire options from 0.25ct to 3.00ct+), color grade, clarity tier, metal purity, tone (yellow, white, or rose), ring size, and band width. Production requires 15–35 business days to accommodate custom casting and independent third-party lab certification. This slender shank profile is explicitly engineered to sit flush against standard wedding bands, making it an excellent choice for daily wear without catching on fabrics. Crafted in Surat — the city that cuts 90% of the world’s diamonds — and shipped factory-direct.
