0.50ct Lab Grown Diamond Princess Cathedral Solitaire Ring

The Stone(s)

The center of this solitaire design features a single 0.50-carat princess-cut laboratory-grown diamond, measuring with sharp, unmodified 90-degree right-angle corners. Selected from our standard colorless stock of E-F color and VS clarity, the stone displays exceptional light dispersion across its crown chevron facets, remaining entirely eye-clean. Every diamond is independently graded, featuring a laser-inscribed report number on the girdle verifiable at official laboratory registries. In strict compliance with BIS IS 19469:2025 and FTC guidelines, our laboratory-created diamonds share identical optical, physical, and chemical properties with mined diamonds, reflecting factory-direct production efficiencies rather than artificial scarcity.

The Setting

The architecture uses an elevated cathedral-style profile, engineered to raise the table facet and maximize light entry from underneath the stone’s girdle. Four low-profile precious white metal claws grip the corners securely, minimizing metal mass while protecting the vulnerable points of the princess cut. Structurally, the open-aperture gallery integrates a dedicated V-shaped under-rail that fully supports the pavilion. This two-tone execution shields the colorless diamond from the warm hue reflection of the main yellow gold ring shank, maximizing light performance without sacrificing setting security.

Metals and Finish

This piece is standard-built using 14K yellow gold (585 purity), delivering an optimal structural balance of pure gold content and daily wear durability. The flat-faced shank maintains a uniform width along the lower perimeter, transitioning smoothly into the high-polished cathedral shoulders. For active lifestyles or alternative preferences, the setting can be customized across our full five-tier metal catalog: 950 Platinum for maximum prong security and density, rich 18K Gold (750), structural 14K Gold (585), scratch-resistant 10K Gold (417), or high-reflective 925 Sterling Silver. All gold alloys are available in high-polish yellow, rhodium-plated white, or rose tones.

Customisation and Origin

Every order enters our verified manufacturing pipeline, bypassing traditional retail markups. Following checkout, our team contacts you via WhatsApp or email within 24 hours to confirm exact specifications, including quarter or half-ring sizes, metal tier, and band width adjustments. Standard custom orders undergo a production timeline of 15–35 business days; third-party lab processing for custom certifications may add 3–10 business days outside our direct control. Shipments above ₹10,000 within India are dispatched via Blue Dart or Delhivery (2–7 business days), while international express shipping via DHL, FedEx, or UPS takes 5–7 business days with insurance and signature required. Returns are accepted within 7 calendar days strictly for items damaged in transit or materially different from the specifications confirmed during your 24-hour workshop consultation. The low-profile under-rail keeps the princess stone stable, making this cathedral profile sit comfortably against the finger for uninterrupted daily wear.
