2.52 Ct. Ruby from Mozambique

This heart shaped ruby is a technical exemplar for designers seeking a statement center stone for custom jewelry, certified by GRS, transparent, and presented in a vivid red hue. The weight is 2.52 carats, with precise measurements of 7.57 x 8.76 x 4.67 mm, yielding an average diameter of approximately 8.16 mm and a depth ratio of about 57 percent, a proportion that balances face up presence with optimal light return. Origin is Mozambique, and the gem is natural with no enhancement, a quality detail that directly influences color saturation and durability. Clarity is graded as very slightly included when evaluated at eye level, indicating that the internal features are minimal, localized and do not interrupt the overall color field or compromise the integrity of the facet junctions. The color intensity is classified as vivid red, which in combination with the transparency produces a saturated face up appearance even under standard jewelry viewing conditions. The GRS report documents origin, natural state and the absence of enhancement, providing an objective basis for valuation and confidence during the design and commissioning process.

The cutting and finishing details define the optical behavior and suitability of this gem for high end custom work. The cutter elected a mixed brilliant facet arrangement, integrating a controlled brilliant pattern with modified pavilion architecture to preserve weight while maximizing scintillation and color depth. The mixed brilliant approach places compact, well aligned crown facets that disperse light into numerous small flashes, while the pavilion design channels return light to the viewer with broad, even zones of red rather than narrow bright points, a characteristic particularly desirable in rubies where color is the primary attribute. Polish is excellent, producing crisp facet intersections and smooth windows that minimize light leakage and enhance saturation. Symmetry is carefully managed for the heart silhouette, with even lobes and a distinct cleft, a refined outline that facilitates secure prong placement and predictable light behavior when mounted. The very slightly included clarity grade, coupled with the excellent polish and precise faceting, means that visual impact is dominated by color and cut rather than by internal features, which are inconspicuous under normal wear conditions.

From a custom jewelry engineering perspective this 2.52 carat heart shaped ruby is exceptionally versatile, and it is particularly well suited to singular bespoke pieces where shape and proportion inform the design vocabulary. The slightly broad heart proportions indicated by the 7.57 to 8.76 mm measurements provide a generous table and a bold face up area, making the stone ideal for rings intended to read strong from a distance, and for pendants where the lobed silhouette can be accentuated by tapered settings. The approximate 57 percent depth supports common prong and bezel strategies without excessive elevation, permitting low profile gallery constructions or more prominent basket settings, according to design requirements. For rings, a three or four prong mounting that secures the cleft with a protective trough or bridge reduces risk at the vulnerability of the cleft while preserving light entry. For pendants, a custom bail that follows the curve of the lobes will maintain symmetry and minimize torque on the setting. Designers seeking to enhance perceived size often pair this ruby with a delicate halo of melee diamonds or small color matched rubies, the mixed brilliant cut favoring small accent stones by providing consistent scintillation contrast. Metal choices will affect perceived warmth and contrast, with 18 carat yellow gold intensifying warmth, platinum offering stark contrast and structural security, and rose gold harmonizing with the vivid red tone. For bespoke commissions The Natural Ruby Company can provide the GRS dossier, high resolution images, and collaboration on prong profiles, bezel thickness, and setting architecture to ensure that the final piece preserves the natural character and optical performance of this Mozambique ruby while meeting the mechanical requirements of everyday wear.
