Three Stone Emerald Ring 0.48 Ct., 18K White Gold

This wedding set is engineered as a precision matched combination of engagement ring and wedding band, designed to present as a single, unified piece when worn together. The engagement ring and band share a contour lock geometry, the band following the crown profile of the engagement head so that the two rings nest with minimal voids, eliminating glare producing gaps and preserving a continuous silhouette. The illustrated example uses a double shank profile where each shank is milled to identical cross sectional radii, producing a consistent visual mass and balanced finger footprint. The seat and inner edge tolerances are machined to a fraction of a millimeter so that the engagement ring and wedding band register repeatedly in the same orientation, preventing rotation and optimizing the articulation of light between the stones. The gallery is engineered with a low cathedral crown to maintain a modest overall height, while the openwork beneath the center position enhances light return into the pavilion of a faceted center gem. The setting employs prong geometry that can be specified to accept a range of center shapes, with collar options to secure different girdle thicknesses without changing the external fit. Surface finishing options include a high polish mirror finish, a brushed satin finish to reduce apparent thickness, and precise edge beveling for comfort fit interiors.

The three stone arrangement is executed to communicate narrative through proportion and optical balance, often evoking past, present, and future. The center position is designed to carry primary visual weight and is proportioned relative to the adjacent half moon side stones so that the three stones read as a cohesive unit, with the side stones cut and matched to the center to equalize brilliance and fire. The side stones specified are half moon diamonds, typically faceted in a modified brilliant schema to maximize scintillation along the semicircular plane, with carefully managed girdle thickness to minimize transition zones between straight and curved facets. The center stone can be deployed as a sapphire, ruby, or emerald, and each requires specific faceting and setting considerations, sapphires being efficiently cut in mixed brilliant or step and brilliant hybrids to maximize color saturation while controlling windowing, rubies benefiting from slightly deeper pavilion depths to enhance color intensity, and emeralds frequently presented in step cut tables to showcase color with minimal faceting that can accentuate internal character. Cut grades are matched across stones when diamonds are used for the side elements, with recommended parameters such as excellent to very good polish and symmetry, table and pavilion angles tuned to the gem type, and clarity grades selected to ensure optical cleanliness under loupe inspection while balancing budgetary constraints.

Metallurgy and fabrication techniques are central to the final performance of the set, and we offer a broad palette of alloys to tune color, hardness, and wear characteristics. Available alloys include 14K rose gold, 18K rose gold, 14K white gold, 18K white gold, 14K yellow gold, 18K yellow gold, platinum 950, and combinations that integrate white and yellow or yellow and white in two tone arrangements. The K values denote gold content which directly affects hardness and hue, with 18K offering richer color saturation and slightly lower tensile strength than 14K, and platinum 950 offering superior density and hypoallergenic properties with a distinct cool gray luster. White gold options are rhodium plated for enhanced whiteness and scratch resistance, and rose gold achieves its warm salmon hue through controlled copper percentages that also increase hardness. Fabrication is executed using CAD modeling and precision lost wax casting followed by hand finishing, with solder joins invisibly blended and hand burnishing applied to set junctions for seamless transitions. Stone setting is performed by experienced setters who hand seat each half moon diamond into a precision milled notch, inspect girdle parallelism, and finish prongs with calibrated burnishing force to maintain stress free retention. Engraving options include machine laser inscription for text or serial numbers, classic hand engraving for decorative scripts, and deep relief engraving for longevity, each applied to a comfort fit interior to preserve wearability.

Customization options are extensive and designed for clients with technical preferences. Center stone selection can be specified by species, approximate carat weight, and preferred cut, with options including round, oval, cushion, and emerald cut shapes chosen to complement side stone geometry. For colored gemstones we provide guidance on color parameters, recommending sapphire hues concentrated in medium to deep saturation with even tone for maximum contrast against half moon diamond accents, ruby selections with strong red saturation and minimal brown modifiers for optimal presence, and emeralds with medium to strong tone and vivid green saturation while noting the commonality of natural internal characteristics which are stabilized and accounted for in setting design. Side diamonds are recommended in the near colorless range with G to H color and VS1 to VS2 clarity for a balance of brilliance and value, though higher grades are available upon request. Structural variations include lower profile prong heads for reduced snagging, bezel or partial bezel encirclement for additional security, split shank widening for visual heft, milgrain treatments along the band edge for a vintage aesthetic, and undergallery filigree for additional light dynamics. Each custom order is accompanied by a specification sheet documenting metal alloy composition, gemstone weight and proportions, facet schematic, and recommended care, and we provide certification options and a clear production timeline. For technical consultations regarding exact cut parameters, facet angles, and matching strategies for mixed gem types, we are available to review CAD renders and stone reports to ensure the finished set meets precise optical and structural goals.
