Lab Grown Diamond Princess Cathedral Pave Ring 1.58 ctw Gold

The Stone(s)

The architectural center of this ring is a 1.40 carat princess-cut lab grown diamond. The stone is independently graded as F color (colorless tier) and VS1 clarity, ensuring an entirely eye-clean table with no visible internal inclusions under naked-eye observation. The geometric chevron faceting pattern across the pavilion is cut to Excellent proportions, directing light return upwards through a high table percentage for sharp, crisp scintillation.

The shoulder and upper shank are flanked by 18 round brilliant lab grown diamonds totaling 0.18 carats. These accent stones maintain an E-F color range and VS clarity, providing a uniform field of surface brilliance that complements the linear geometry of the princess cut. Every center stone is certified by the International Gemological Institute (IGI) with a unique report number laser-inscribed on the girdle.

The Setting

Engineered for both geometric precision and structural integrity, the center stone is anchored within an elevated cathedral setting. Four heavy, V-shaped corner claws encase the sharp, vulnerable corners of the princess cut, protecting them against lateral impact while maintaining a low-profile grip on the stone’s girdle.

The cathedral shoulders rise sharply from the shank to meet the head, creating an open gallery structure beneath the pavilion. This architectural layout leaves the lower pavilion facets exposed to maximum ambient light entrance, amplifying the diamond’s natural refractive performance while creating a distinct negative space under the culet.

Metals and Finish

The default mounting is cast in solid 14K gold (585 purity purity stamp), delivering an optimal industrial balance between fine gold content and structural rigidity for daily wear. The alloy composition is formulated to resist deformation, ensuring the 18 shared-prong pavé settings along the band remain perfectly aligned over time.

Beyond 14K gold, this design can be rendered in 10K gold (417) for enhanced scratch resistance, 18K gold (750) for a richer hue, or 950 platinum (95% pure platinum) for the ultimate tier of prong security and a completely hypoallergenic profile. The default finish is a flawless high-polish surface, though satin, brushed, and matte finishes are available upon confirmation.

Customisation and Origin

Every ring is made-to-order and fully customizable through our workshop pipeline. Standard center-stone carat weights can be scaled across predefined tiers including 0.50ct, 1.00ct, 1.50ct, 2.00ct, and 3.00ct+, with color ranges adjustable from D to I and clarities from VVS1 down to VS2. Sizing is calibrated precisely to quarter and half-size international standard charts.

The squared edge profile of the pavé band ensures that this ring sits comfortably flat against standard wedding bands, making it a practical choice for daily engagement wear without spinning. Following checkout, our design team will contact you via WhatsApp and email within 24 hours to verify your exact specifications, ring sizing, and metal selection before CAD production begins.

The standard manufacturing window requires 15–35 business days for precision casting, setting, and independent laboratory certification processing. Crafted in Surat — the city that cuts 90% of the world’s diamonds — and shipped factory-direct.
