The Stones
The center of this architectural signet band features a single, independently graded 0.62 carat round brilliant lab grown diamond. Positioned as the focal point of the wide shank, the stone is selected from our D-E-F colorless stock, ensuring zero visible body color, paired with an eye-clean VS clarity profile that eliminates structural inclusions to the naked eye. The stone features an Excellent cut grade, balancing standard brilliant proportions to maximize internal fire, scintillation, and light return through the table facet. Every lab grown diamond used possesses identical optical, physical, and chemical properties to mined stones, verified by independent third-party certification.
The Setting
The architecture relies on a specialized hybrid setting, utilizing four low-profile prongs nested directly within a recessed square step-bezel frame. This engineering choice serves a dual purpose: the square step-faceted border creates a sharp, geometric frame that visually enhances the linear presence of the band, while the deep-set flush alignment protects the diamond’s girdle from daily impact. The low-profile prong integration ensures the stone remains secure and snag-proof for active wear. Below the setting, a precision-machined open under-gallery window allows light to enter from beneath while facilitating straightforward cleaning and maintenance.
Metals and Finish
Forged with a solid metal mass, the ring has a gross weight of 6.084 grams, containing a net metal weight of 5.960 grams of solid 14K yellow gold (585 purity code). The shank is meticulously finished with a uniform high polish across its wide, flat shoulders and tapering band walls. For structural customization, the design can be ordered across five distinct metal tiers: 10K gold for maximum scratch resistance, 14K gold for an optimal balance of gold content and durability, 18K gold for a rich tonal hue, 950 platinum for ultimate prong density and hypoallergenic properties, or 925 sterling silver for casual wear.
Customisation and Origin
Each band is built completely to order based on the wearer’s precise structural requirements. Standard sizing accommodates quarter and half-size increments on international charts, while the central setting can be recalibrated for standard stone carats ranging from 0.25ct up to 3.00ct+.
