Lab Grown Diamond Round Brilliant Architectural Dome Ring 18K Yellow Gold 2.06 ctw (86 Diamonds)

The Stones

The architectural centerpiece of this design is a 1.00 carat round brilliant lab grown diamond, independently graded by IGI with an Excellent cut grade, F color, and VS1 clarity. This stone displays optimized light distribution and sharp contrast across its facets. Encircling the center stone is a multi-level field of 69 micro-pavé round brilliant lab grown diamonds totaling 0.34 carats, offering continuous light return across the dome’s curvature. An outer concentric collar features 16 radially arranged marquise-cut lab grown diamonds (0.72ctw, EF color, VS clarity), framing the central setting with a structural, geometric silhouette. All accent diamonds are selected within strict eye-clean boundaries; inclusion tiers below VS2 are not maintained in standard production stock.

The Setting

The engineering of this heavy statement piece balances secure stone anchoring with a multi-layered profile. Four low-profile claws grip the center stone’s girdle, providing an elevated cathedral carriage that elevates the diamond above the accent tiers. Beneath the primary setting, an openwork gallery structure incorporates custom filigree scroll under-galleries. This filigree framework acts as an engineered structural support for the wide stone platform while maximizing light entry paths to the pavilion facets of the micro-pavé and marquise arrays. The stones are positioned close together in a shared-prong configuration along the gallery periphery, creating an integrated field of diamonds that minimizes visible metal borders.

Metals and Finish

This piece is built by default in solid 18K yellow gold (750 purity), selected for its rich hue that deepens the visual presence of the openwork scrollwork. The substantial gold weight of 9.550 grams provides the structural integrity required to support complex multi-stone dome settings without warping over time. The solid lower band is finished with a high-polish reflective surface that tapers uniformly from the detailed split-shoulder geometry of the upper shank. The ring can alternatively be commissioned in 950 Platinum for ultimate density and hypoallergenic properties, 14K gold (585) for everyday durability, or 10K gold (417) for active-wear scratch resistance, across white, rose, or yellow tones.

Customisation and Origin

Every ring is made-to-order according to individual specifications. Standard center carats scale through 0.25ct to 3.00ct+ tiers, with customizable color ranges from D to I and clarity grades from VVS1 to VS2 available during the post-purchase alignment. The split-shank architecture can be adjusted to exact half or quarter ring sizes.
