4.33 Ct. Ruby from Mozambique

This AGL certified ruby presents a definitive example of quality and presence, centered on its weight of 4.33 carats. The weight alone places this stone within a class of rubies that are sought after for their combination of visual impact and rarity, making it notable for both collectors and designers. The gem shows an orangish red hue with intense color intensity, a characteristic that is particularly desirable in rubies when paired with a substantial carat weight. Sourced from Mozambique and accompanied by AGL documentation, this 4.33 carat oval ruby from The Natural Ruby Company communicates provenance, measured quality, and assurance in its origin attribute and basic gemological identity.

The physical and cutting specifications are measured and precise. The stone is cut in an oval shape with a mixed brilliant facet arrangement, and it measures 10.47 by 8.81 by 5.32 millimeters. The mixed brilliant cut combines pavilion and crown facet orientations to optimize both color saturation and light return, while the excellent polish ensures clean facet junctions and refined surface finish. Clarity is graded as slightly included when evaluated at eye level, which indicates natural internal features that do not significantly detract from face up appearance, especially given the stone size and intense color. Enhancement is limited to heat treatment, a stable and widely accepted practice used to improve color and clarity in natural rubies, and the AGL certification records the treatment and confirms gem identification.

The weight of 4.33 carats directly informs the stone quality and its suitability for prominent jewelry applications. At this carat weight, the ruby is large enough to function as a principal center stone in rings, pendants, or bespoke pieces, providing a visible and balanced area of color without requiring exceptional mounting size. The interplay between carat weight and the proportions measured yields a substantial visual presence on the hand, as demonstrated in scale images, where the oval geometry and the mixed brilliant facet pattern produce lively color flashes and a well saturated overall tone. Larger natural rubies with intense color and good polish are comparatively uncommon, and the 4.33 carat weight contributes materially to the gemstone market value and desirability, while the slightly included clarity grade maintains transparency and depth of color while confirming the natural origin of the stone.

Practical considerations for handling and setting this ruby are straightforward, and The Natural Ruby Company provides comprehensive documentation to support appraisal and insurance needs. Heat treatment in rubies is stable under normal wear conditions, and routine care consisting of gentle cleaning with mild detergent and a soft brush is recommended. For secure and aesthetic mounting, settings that support the pavilion and protect the girdle are advisable, and designs that present the table to light will maximize the mixed brilliant cut performance. The accompanying AGL certificate provides a permanent record of origin, weight, dimensions, cut description, clarity commentary, color intensity assessment, polish grade, and disclosed enhancement. For clients requiring additional measured details or custom mounting options, The Natural Ruby Company can supply the certificate and high resolution images as part of the documentation package.
