5.09 Ct. Ruby from Mozambique

This oval 5.09 carat ruby measures 11.60 by 9.77 by 4.99 millimeters, presenting a length to width ratio of approximately 1.19, a proportion that preserves face up presence while minimizing light leakage. The gem is executed in a mixed brilliant cut, combining a brilliant facet arrangement on the crown with a pavilion configuration tuned to retain color and weight, the result being a balance between scintillation and saturated tone. Polish is graded excellent, evident in the crisp facet junctions and smooth pavilion planes, which enhance the gem response under point source lighting. Clarity is graded included when evaluated at eye level, the inclusions being consistent with natural Mozambique corundum and not compromising durability or optical performance. The stone was heat treated, a stable and industry accepted enhancement that improves transparency and refines chroma, and the overall transparency reads as transparent to gemological observation, enabling strong light interaction across the mixed brilliant facet pattern.

Color is pinkish red with an intense color intensity, a combination that situates the gem in a visually compelling hue field, more towards the red pole than a purely pink tone while retaining a slightly feminine warmth. This specific balance of pink and red distinguishes it from pigeon blood rubies, which typically exhibit a purer saturated red, and yet the intensity here rivals many historical examples in terms of visual impact when set. If one considers famous rubies such as the Sunrise Ruby in terms of sheer color saturation and presence, this Mozambique gem cannot be equated on carat weight, however it shares an analogous ability to read rich and lively in varied light. Compared to classic Burmese stones, celebrated for their deep, velvety red, this specimen offers a brighter pinkish overtone, imparting a distinct personality that can be more versatile in contemporary jewelry design. The inclusions present in this stone are diagnostic of natural formation, and when viewed alongside the intense chroma they contribute to the gem narrative of authenticity and origin. The geographic provenance of Mozambique imparts a known suite of trace elements and inclusion signatures, which experienced connoisseurs recognize as part of the regionally distinct ruby typology.

From a lapidary and setting perspective the mixed brilliant cut was chosen to maximize color retention for a gem of this depth and table dimensions, while preserving as much carat weight as practical from the rough. Facet planning focused on optimizing crown angles to promote lively return and pavilion geometry to avoid a dark window, making the gem well suited for both closed back and open back mounting, although a closed setting can deepen the perceived color if desired. Because the clarity is included at eye level, recommended mounting styles include protective prong engineering with reinforced shoulders, or a bezel setting for high wear jewelry, both approaches enhancing security while allowing the excellent polish to present uninterrupted. The stone will exhibit pronounced face up color at standard viewing distances, and under direct lighting the mixed brilliant cut generates a pleasing balance of flashes and color. In terms of craftsmanship and certification, The Natural Ruby Company provides detailed documentation of heat treatment and origin, and our quality control confirms facet symmetry and polish quality according to professional gemological criteria. Collectors who appreciate historical parallels will value this piece for its capacity to channel the spirit of famous rubies, delivering robust color intensity and classic corundum character in a size that is rare for Mozambique material of such clean polish.

This ruby represents an intersection of material provenance, cutting strategy, and market practicality, offering a tangible alternative to larger but more heavily included historical pieces, and a distinct personality compared to the deeply saturated Burmese specimens prized by traditionalists. It is a gem that reads as lively and modern when set in contemporary styles, while still carrying the gravitas associated with storied corundum examples. The Natural Ruby Company stands behind the authenticity and recorded treatment history of this gem, and we can provide further imaging under different lighting, facet analysis, and setting mockups upon request. For the customer who seeks a technically vetted ruby with intense pinkish red color, excellent polish, and a thoughtful mixed brilliant cut designed to accentuate both brilliance and color, this 5.09 carat Mozambique stone is a rigorous choice, combining gemological integrity with design flexibility and enduring aesthetic appeal.
