0.71 Ct. Ruby from Mozambique

This 0.71 carat round ruby from Mozambique represents a rare intersection of natural origin, precise craftsmanship, and visual performance, and The Natural Ruby Company is proud to present it to discerning buyers. Weighing 0.71 carat, this gem occupies an important niche in the pricing curve, where per carat value begins to climb appreciably for untreated stones with intense color and high clarity. The importance of the 0.71 carat weight cannot be overstated, because in natural ruby supply, every fraction of a carat reflects the yield of the original rough crystal, and untreated material of this quality is comparatively scarce. The weight combined with a face diameter of 5.97 by 5.91 millimeters and a total depth of 2.47 millimeters yields a depth to diameter ratio of approximately 41.6 percent, a profile that has been deliberately optimized to maximize face up spread and color saturation, giving the apparent size and color presence that buyers value in everyday wear.

The cutting and finishing of this stone are executed to exacting standards, the gemstone cutting style is faceted, employing a mixed brilliant cut that marries a brilliant facet arrangement on the crown with a precisely calibrated pavilion geometry to balance scintillation and color return. This mixed brilliant approach allows the pavilion to be tuned so that light enters and is returned with minimal leakage, while the brilliant crown facets scatter light into lively flashes. The result is a dynamic interplay of pinpoint brilliance and broad flashes of saturated red, which is particularly desirable in ruby because it enhances perception of depth of color. The polish grade is excellent, each facet junction is clean and crisp, and facet symmetry is controlled to ensure uniform light behavior across the table and crown. The relatively shallow depth percentage increases the gem’s face up presentation, making the 0.71 carat size read larger than its weight alone would suggest, a practical advantage for settings where visual presence is critical.

Color and clarity are the defining quality parameters of this ruby. The stone exhibits intense color intensity, a concentrated red that reads as pure and vibrant in daylight and electric light, characteristics often associated with Mozambique origin material. The absence of enhancement is a principal value driver, because natural, untreated rubies with intense color command a premium compared with heat treated or otherwise enhanced material. The clarity grade is very slightly included, evaluated at eye level, which indicates the presence of minor internal features that do not materially affect transparency or the gem’s ability to transmit and return light. Those inclusions serve as natural identification fingerprints, confirming natural origin and the lack of treatment, while remaining sufficiently minor so as not to detract from the visual experience. Collectors and connoisseurs will appreciate that the stone combines an intense, unassisted color with excellent optical performance, a combination that is unusual in the market and that enhances long term value.

From a valuation and rarity perspective, the 0.71 carat weight plays a pivotal role. Rubies are priced on a per carat basis that escalates nonlinearly with size for comparable color and clarity. Small increases in carat weight can move a gem into a higher price bracket, and an untreated ruby of this size with intense color and very slight inclusions from Mozambique is relatively uncommon, enhancing its investment potential. The cutting strategy, a mixed brilliant faceting with an excellent polish, has been applied to preserve as much of the original rough as possible while delivering optimal optical performance, an approach that conserves weight without sacrificing face up color and brilliance. The Natural Ruby Company offers this gem as an example of how careful selection of rough, expert cutting, and the intrinsic attributes of origin and lack of enhancement converge to produce a stone whose 0.71 carat weight, measured dimensions, and superior finish combine to create both immediate visual appeal and long term rarity value.
