3.09 Ct. Ruby from Mozambique

A rare opportunity awaits the collector and the connoisseur, a single natural ruby of exceptional presence offered by The Natural Ruby Company. This transparent ruby weighs 3.09 carats, shaped into a cushion form that measures 9.61 by 7.42 by 4.57 millimeters, cut as a mixed brilliant to combine the scintillation of modern faceting with the soft, classical silhouette of a cushion. Its purplish red hue registers as vivid in color intensity, a tone that reads luxurious and alive in every light. The clarity is evaluated as very slightly included at eye level, a quality that speaks to honesty of origin and character rather than artificial perfection, and the polish is excellent across every facet, producing a window into the stone where color and light play together. Importantly, this ruby is untreated, with no enhancement, and it originates from Mozambique, a source that in recent years has produced some of the world’s most desirable and collectible rubies. For a client seeking exclusivity, owning a natural, untreated ruby of this caliber means securing a piece that is both scarce and authentic, a jewel to define a bespoke collection.

Look at how this ruby breathes when held to light, how the mixed brilliant cut disperses fire while the cushion outline maintains a generous face up area, allowing the purplish red to appear saturated without sacrificing brilliance. The transparency allows internal flashes of pink and red to emerge as the stone moves, and the very slightly included clarity is visible only upon close inspection under ideal viewing conditions, giving the gem a lived in, natural depth that many collectors prize. The proportions, with a length to width ratio that is neither elongated nor squat, make this gem wonderfully versatile, capable of reading as bold and central in a solitary presentation, or elegant and intimate when set within more intricate settings. The excellent polish ensures that light encounters smooth, reflective planes, and the mixed brilliant pavilion works to return light efficiently to the eye, enhancing perceived size and vivacity. For those who appreciate provenance, the Mozambican origin adds a contemporary narrative to the gem, combining geological story with modern mine to market craft.

Customization is where this ruby truly transforms from a single extraordinary stone into a uniquely personal jewel, because its dimensions, cut, and color invite a wide variety of settings and treatments within fine jewelry. Imagine the ruby set as a classic solitaire ring with four slim prongs in 18 karat yellow gold, the warm metal amplifying the stone’s purplish red glow, or envision the same stone embraced by a halo of small brilliant cut diamonds in platinum for an elevated engagement piece that reads as high jewelry. A bezel setting would provide contemporary security for daily wear, while an open gallery and long claw prongs would create a taller, more dramatic silhouette for cocktail occasions. For a vintage inspired creation, a millegrain engraved mount with delicate filigree would complement the cushion form, and for a modern aesthetic, a tension mount or an east west orientation could play with negative space and visual balance. The ruby can anchor a three stone composition flanked by trapezoid or emerald cut diamonds, be the focal point of a pendant with a hidden bail for seamless flow, or become the head of a brooch or a statement earring when paired with contrasting gemstones. Metal and finish choices further expand the custom palette, with rose gold adding romantic warmth, white gold creating a sharp contrast to enhance brilliance, and platinum providing a durable, luxurious frame. We can refine details such as prong profile, bezel height, gallery openness, and setting temperature for everyday versus occasional wear, because each of those decisions affects the way the color and light speak from within the ruby.

At The Natural Ruby Company we treat each commission as a private collaboration, a chance to translate a single superior gem into an heirloom piece that reflects individual taste and intention.
