3.01 Ct. Ruby from Mozambique

This oval shaped ruby is a GRS certified natural gem, presenting a vivid red hue with a weight of 3.01 carats, and exact dimensions of 8.84 x 7.42 x 5.15 mm. The gem is cut in an oval outline with a mixed brilliant cut, combining step and brilliant faceting to maximize both depth of color and internal brilliance. Transparency is high, and the clarity is graded as very slightly included, evaluated at eye level, which indicates inclusions are minimal and do not detract from overall visual appeal in typical viewing conditions. The polish is excellent, and the stone has undergone no enhancement, a detail confirmed by the GRS report. This combination of certified natural origin, absence of treatment, and precise cutting delivers a ruby that is both technically well specified and visually striking, and is offered through The Natural Ruby Company.

The color of this ruby is its defining attribute, described on the report as vivid red, a designation reserved for stones with intense saturation and strong hue purity. The mixed brilliant cut plays an important role in presenting this color consistently across different lighting conditions, producing lively flashes of light while preserving the stone’s deep core tone in direct and diffuse light. When viewed face up, the stone exhibits an even spread of color with concentrated saturation toward the center, creating a sense of vitality and depth. The balance between saturation and tone is such that the red reads as richly saturated without appearing overly dark, allowing facets to return bright red highlights and subtle flashes of lighter red as the gem moves.

Clarity and cut quality together determine the visual cleanliness and scintillation of the stone. With a clarity grade of very slightly included at eye level, the inclusion profile is modest and does not disrupt the eye appeal or the face up brightness in ordinary wear. The mixed brilliant faceting pattern is executed to commercial precision, producing a pleasing pattern of light return across the crown and pavilion, and the excellent polish ensures crisp facet junctions and minimal surface blemishes. The proportions implied by the dimensions produce a substantial spread for a 3.01 carat oval, making this gem visually larger than many round counterparts of similar weight. Photographic scale references illustrate how the gem sits comfortably for rings, pendants, or bespoke settings that emphasize the oval silhouette and lively internal reflections.

Rubies are a durable choice for fine jewelry due to their position as the red variety of corundum, with a Mohs hardness of 9, second only to diamond for commonly used gemstones. This inherent hardness contributes to long term resistance to scratches and abrasions, preserving facet sharpness and polish through years of wear. For routine care, warm soapy water and a soft brush are effective for removing surface oils and dust, and professional cleaning is recommended prior to any ultrasonic or steam cleaning, particularly for any stones with internal features. Proper setting, such as protective prongs or a bezel for rings worn daily, will minimize exposure to knocks while allowing the mixed brilliant cut to display optimal brilliance. The absence of enhancement further supports confidence in the stone’s stability, as untreated rubies retain their natural color and structure without the concerns associated with certain treatments.

The GRS certification and Mozambique origin together provide verifiable provenance and treatment history, offering assurance to collectors and designers who prioritize natural, untreated gems. Mozambique has become a reputable modern source of fine rubies, and this specimen exemplifies the combination of vivid color, clarity, and ethical traceability that discerning buyers seek. Over the years the stone’s vivid red will continue to captivate because color stability is intrinsic to natural, untreated corundum, and because the excellent polish and robust hardness preserve surface condition and brilliance. The Natural Ruby Company stands behind the gem’s report and presentation, and the stone is well suited for a timeless setting that will age gracefully while remaining a focal point of fine jewelry collections for generations.
