0.52 Ct.Tw.Total Carat Weight Ruby Pair from Mozambique

This matched pair of round rubies presents a technical balance of proportion, symmetry, and optical performance, each stone precisely documented to assist design and setting decisions. The stones weigh 0.25 carats and 0.27 carats, and measure 3.87 by 3.87 by 2.32 millimeters and 3.82 by 3.83 by 2.57 millimeters respectively. Both are finished in a mixed brilliant cut, a cutting grammar that combines a brilliant style crown with a modified pavilion profile, allowing for controlled light return and positional stability when used as paired accents. Clarity is graded as very slightly included, evaluated at eye level, indicating small internal features that do not materially interrupt transparency or light transmission. The polish is excellent, ensuring crisp facet junctions and mirror like facet planes that maximize specular reflection and preserve the cutter s intended optical performance.

From a faceting and symmetry perspective these rubies are engineered to showcase matched performance in a pair application. The mixed brilliant cut generates a star pattern across the table when viewed face up, and the alignment of crown and pavilion facets in these examples is precise, producing symmetrical light return across both stones. The first stone exhibits a depth that is approximately 60 percent of its diameter, and the second stone exhibits a depth that is approximately 67 percent of its diameter, metrics that influence the balance between brilliance and color depth. The slightly deeper pavilion of the second stone increases internal light path length, enhancing perceived color saturation when set face up. The excellent polish and consistent girdle finishing support tight setting tolerances, permitting minimal bezel or prong material to distract from the stones optical presentation.

Color is the defining attribute of these rubies, described as a pinkish red hue with intense color intensity, a characterization important to connoisseurs who distinguish hue, tone, and saturation in matched pairs. The pinkish red hue retains a lively red center, while the intense saturation provides strong chroma without moving into over dark tones, which can suppress brilliance. Under directional lighting the stones demonstrate a lively combination of bright flashes and smaller scintillation, reflecting the mixed cut s capacity to disperse and return light while maintaining color presence. Heat treatment has been applied as a standard enhancement to improve both hue uniformity and clarity, and the effect is a more homogeneous color distribution and reduced disruption from microscopic inclusions, while preserving natural chromium driven absorption that creates the characteristic red response.

These rubies originate from Mozambique, a source known for producing material with robust red tones and good crystallographic quality, and they are presented by The Natural Ruby Company with full specification for professional evaluation. The near match in weight, diameter, hue, and polish makes this pair especially suitable for symmetrical applications such as stud earrings, matched accents in a pendant, or as precision set components in bespoke jewelry. For bench considerations the faceting consistency, excellent polish, and small but stable gullets and girdles reduce the risk of movement or light leakage once mounted, providing predictable assembly outcomes. For buyers who prioritize technical attributes these stones offer a coherent package of documented dimensions, repeatable optical behavior, and mature heat enhancement, providing a reliable foundation for high quality design and finishing.
