4.11 Ct. Ruby from Mozambique

This transparent Bellerophon certified Vivid Red pigeon blood ruby presents precise, verifiable attributes that are important for designers and clients who require clarity in specification. The stone weighs 4.11 carats and is cut into an oval measuring 10.74 by 8.61 by 5.05 millimeters. The cutting style is a mixed brilliant, which combines step and brilliant facets to balance depth of color with lively light return. Color has been graded as vivid, in the pigeon blood category, a designation that describes a saturated, slightly bluish red that remains vivid under standard lighting. Clarity is evaluated as slightly included at eye level, indicating the presence of minor natural inclusions visible under close inspection but not significantly impairing transparency or brilliance. The polish is excellent, producing clean facet junctions and strong surface luster. The stone is heat treated, a stable, commonly accepted enhancement for rubies, and its origin is Mozambique, as documented in the accompanying Bellerophon report. These objective details make the stone straightforward to specify for bespoke work and to document on invoices and appraisal reports.

The 10.74 by 8.61 millimeter oval format and the 4.11 carat weight combine to make this ruby exceptionally well suited as a center gem in custom jewelry. The oval silhouette provides a classical yet versatile profile that elongates visual lines when set on a finger, and its proportions are well balanced for both solitaire and halo designs. The 5.05 millimeter depth yields a durable pavilion that allows secure prong or bezel settings without excessive protrusion, and the mixed brilliant facet arrangement enhances scintillation while preserving the intense pigeon blood color. For ring settings, four or six prongs are both appropriate depending on the design; four prongs create a more open look emphasizing length, while six prongs offer added security for daily wear. Bezel settings are readily accommodated by the depth and provide optimal protection for active lifestyles. For pendants, the oval profile sits comfortably on a variety of bails and lends itself to both straight and tilted orientations. As a single, well-documented ruby, it is also an excellent candidate for a signature solitaire commission where the quality of the stone is intended to be the focal point.

From a practical bench and design perspective, the precise dimensions and certification streamline the customization process. Jewelers can plan seat and gallery dimensions using the exact millimeters provided, and the slightly included clarity grade advises on strategic pavilion orientation or accent placement to minimize the visibility of any internal features. Metal selection can be guided by the vivid pigeon blood color; 18 karat yellow or rose gold will emphasize warmth and color contrast, while platinum or 18 karat white gold will accentuate the stone’s vivid red saturation and light return. The mixed brilliant cut benefits from a halo of small brilliant-cut diamonds when additional sparkle is desired, and tapered side stones can visually lengthen the oval for a more dramatic finger profile. The heat treatment reported is stable for routine wear, however standard care practices are recommended, including periodic professional inspection of the setting, cleaning with mild soap and water, and avoidance of harsh chemicals and extreme temperature shocks. The Natural Ruby Company provides the Bellerophon certificate with this stone, supporting provenance and treatment disclosure, and stands available to provide any additional measurements, high-resolution imaging, or mounting recommendations required by a jeweler prior to final setting.
