0.43 ctw Lab Grown Diamond Round Helix Tapered Pendant 14K Gold

The Stones

The focal engineering of this pendant relies on a continuous field of surface light formed by 115 round brilliant lab grown diamonds. With a calculated total weight of 0.43 ctw, these stones are separated into two distinct architectural groups: the vertical stabilizing core axis and the tightly wound helical ribbon. Every diamond is selected within the G-H near-colorless range and graded at VS clarity, ensuring an entirely eye-clean presentation with no inclusions visible to the naked eye. The stones feature an Excellent cut grade to maximize internal light reflection through the open skeletonized cage structure. Each diamond shares the exact optical, physical, and chemical properties as mined diamonds, verified by IGI jewelry certification available upon request.

The Setting

Weight distribution and stone security are handled by a dedicated micro-pavé setting along the three vertical structural rails and the winding spiral ribbon bands. Rather than utilizing bulky traditional prongs that disrupt the geometric profile, the stones are set low into the metal channels with miniature shared claws. This structural choice exposes the crown and table of each round brilliant diamond to maximum ambient light while maintaining a snag-free outer surface. The open internal gallery clearance allows light to enter from the sides and back, illuminating the central core pillar from within the three-dimensional cone framework.

Metals and Finish

Fabricated in standard 14K yellow gold (585 purity code), the pendant provides an optimal balance of structural integrity and gold content, necessary for stabilizing the fine, multi-stone helical ribbons. The interior gold walls are polished to a mirror-like High Polish finish, creating a sharp visual contrast against the diamond-encrusted outer face. The integrated pendant loop at the apex is reinforced to prevent friction wear against a chain. Beyond the default 14K alloy, this design can be ordered in harder 10K gold for maximum scratch resistance, rich 18K gold (750 purity) for enhanced color saturation, or 950 platinum for a dense, hypoallergenic weight profile.

Customisation and Origin

Production options allow for complete adjustments confirmed post-purchase. Within 24 hours of checkout, our workshop team contacts you via WhatsApp and email to verify your exact specifications before any metal is cast. You can modify the metal tier, tone (yellow, white, or rose gold), or request higher stone parameters such as D-E-F colorless tiers or VVS1 clarity. Production requires 15–35 business days (up to 45 business days in rare certification windows) to complete the complex micro-pavé assembly and independent laboratory grading. The geometric elongation of the tapered cone provides a striking vertical accent that elongates the neckline, making it an exceptionally balanced choice for architectural layering over minimalist wardrobe pieces. Crafted in Surat — the city that cuts 90% of the world’s diamonds — and shipped factory-direct.
