0.25 Ct. Ruby from Mozambique

This ruby is a precise and carefully evaluated natural gemstone, weighing 0.25 carat, marquise in shape, and measuring 5.99 by 2.80 by 1.84 mm, with transparent body color and an intense pinkish red saturation, mixed brilliant faceting, and an excellent polish. The cutting style combines a brilliant facet arrangement on the crown with a modified pavilion that maximizes internal light return for a small marquise profile. Clarity is graded as very slightly included at eye level, meaning that inclusions are minor, localized, and do not materially interrupt the optical performance when viewed without magnification. The ruby has been heat treated, a stable and accepted enhancement that improves color and clarity without compromising structural integrity, and the material is sourced from Mozambique, a region known for high quality rubies with strong, saturated hues.

From a faceting perspective the mixed brilliant approach for this marquise balances brilliance and color intensity in a compact 0.25 carat framework, with facet junctions and table proportions cut to elevate both scintillation and overall tone. The stone displays a length to width ratio of approximately 2.14 to 1, which is well suited to classic marquise proportions, providing an elegant elongation while maintaining balanced light distribution from crown to pavilion. The crown has been faceted to create open white light return and controlled flashes of spectral color, while the pavilion facets are calibrated to prevent light leakage that would otherwise weaken perceived saturation. The result is an impression of depth and vividness that is disproportionally strong for a stone of this size, a key consideration for clients seeking maximum visual impact in delicate or cluster settings.

The clarity of very slightly included at eye level translates to excellent practical appearance, with the most common internal features observed as minor crystals or faint needle like inclusions that do not reduce transparency. These natural features often act as facet anchors that contribute to scintillation, and under loupe examination they authenticate the natural origin without detracting from visual appeal. Polish is assessed as excellent, indicating symmetrical facet finish and mirror like surfaces that enhance the return of light and minimize surface diffusion. The heat treatment applied is industry standard, executed to stabilize and intensify the pinkish red hue, and given the hard nature of corundum with a Mohs hardness of 9 the treatment is permanent under normal wear conditions. Origin identification to Mozambique informs trace element expectations, typically higher iron and chromium signatures that produce the saturated warm red tones observed in this specimen.

When considering longevity and how the natural beauty of this ruby will continue to captivate over the years, the combination of material quality, cutting precision, and stable enhancement is central. The intense color is preserved by the inherent hardness and chemical stability of corundum, so routine careful wear and standard professional cleaning will maintain color and brilliance. The marquise silhouette, with its well controlled proportions and polished facet architecture, ensures sustained visual impact whether set as a solitaire, paired as side stones, or used in a pavillion accent application. Mounting recommendations include secure prong work or bezel variants that protect the pointed ends from mechanical stress, and pairing with metals that complement the pinkish red tone such as warm yellow gold to intensify hue warmth, or neutral platinum to emphasize color purity. The Natural Ruby Company stands behind the provenance and the technical grading of this piece, and for collectors and designers seeking a small yet intensely colored marquise ruby, this stone offers a rare combination of optical performance and long term durability, qualities that will continue to draw the eye and retain desirability across generations.
