1.73 Ct. Ruby from Mozambique

This rare Mozambique ruby presented by The Natural Ruby Company is a fine example of classic gemstone beauty and precise cutting, weighing 1.73 carat, oval shape, with dimensions of 7.40 by 5.84 by 4.30 mm, faceted with a mixed brilliant cut, clarity graded as slightly included evaluated at eye level, vivid color intensity, excellent polish, and no enhancement. The mixed brilliant faceting blends step cut elements with brilliant cut geometry to produce a balance of color saturation and scintillation, making this stone ideal for both collectors and bespoke jewelry design. The oval outline preserves more weight than a round of similar dimensions, while the careful pavilion and crown faceting work together to maximize return of light and to emphasize the ruby red saturation that is so prized in natural rubies from Mozambique. For buyers who value transparency of origin and treatment disclosure, this ruby is notable for its documented Mozambique provenance and for the absence of any clarity or color enhancing processes.

Color is the primary value driver in rubies, and this piece displays a vivid red that sits in the desirable range for collectors and connoisseurs. The vivid color intensity indicates a strong concentration of chromium with a balanced presence of iron, a combination often found in high quality Mozambique material, which yields strong red without tipping into overly brownish tones. Under mixed lighting the stone shows consistent saturation across the table and crown facets, a sign of even crystal chemistry and excellent cutting. The natural origin of this gem from Mozambique matters to educated buyers because geological source influences both hue and market perception, Mozambique being recognized for producing richly colored rubies in recent decades that compete with traditional sources. Because this ruby is untreated, its color is wholly natural, and therefore its hue stability and market desirability are enhanced by the absence of color improving interventions.

Clarity has been assessed as slightly included evaluated at eye level, a practical grade that tells experienced buyers that small internal features are present but do not dominate the appearance or reduce transparency significantly. Slight inclusions often consist of thin mineral crystals, healed fractures, or fine silk like growth features, and when small they can contribute to a natural fingerprint that confirms origin, while still allowing exceptional brilliance when the gem is well cut. Evaluated at eye level means that under standard viewing conditions without magnification the inclusions are minor and do not obstruct the visual enjoyment of the stone. From a durability perspective, a slightly included ruby that has been cut with care will perform well in everyday jewelry, provided settings protect any localized features and proper care is observed. The excellent polish on the facets further minimizes the visual impact of inclusions by enhancing light transmission and surface reflection, thereby supporting both aesthetic appeal and long term wearability.

The geometric faceting of this oval mixed brilliant ruby is the aspect that most directly controls its optical performance, and the cutter has applied a precise faceting scheme to allow maximum light play. The mixed brilliant style typically uses a brilliant pattern on the crown to create lively scintillation and a modified pavilion architecture to preserve weight and color, producing an interplay of flashes that change dynamically as the gem moves. Facet junctions are clean and symmetric, which is essential for uniform light return and for avoiding dead areas that absorb rather than reflect light. The proportions, including the depth of 4.30 mm relative to the length and width, suggest a balanced depth ratio that supports both internal reflection and surface brilliance, allowing viewers to perceive flashes of vivid red interspersed with brighter highlights. In practical terms this means the gem exhibits strong brilliance, attractive fire that complements the red body color, and lively scintillation that will animate the stone in a ring or pendant setting.

For the educated buyer, this Mozambique ruby from The Natural Ruby Company represents an appealing combination of natural origin, no enhancement, attractive weight at 1.73 carat, and skilled cutting that maximizes light performance. Natural untreated rubies of this quality are increasingly sought after by collectors who prioritize provenance and long term value, and by designers seeking stones that render vibrant color under varied lighting. This ruby adapts well to a variety of settings, from classic solitaire rings that show off the oval outline, to halo designs that can intensify perceived size and fire, to custom pieces where the cutter is allowed to orient the gem to best display its color and brilliance. We recommend professional certification when precision documentation of origin and treatment is required, and we are happy to assist with laboratory submission or with recommendations for secure custom mounting and insurance appraisal. For a buyer seeking a natural, vividly colored, well cut ruby with transparent treatment disclosure, this piece is a distinguished and reliable choice.
