16.56 Ct. Cabochon Ruby from Mozambique

This listing presents one beautiful translucent 16.56 carat oval shape red ruby, with dimensions 19.10 x 13.60 x 6.10 mm, supplied by The Natural Ruby Company. The gem is fashioned as a cabochon, which emphasizes rich saturated color rather than faceted brilliance. At this substantial carat weight the stone displays a pleasing presence for rings, pendants, or collector holdings, and the oval outline provides classical proportions that work well in both traditional and contemporary settings. The surface exhibits an excellent polish, delivering a smooth mirror like finish across the dome, and the overall translucency allows light to penetrate and reveal depth of hue. Visual inspection at eye level results in a clarity grade of slightly included, a designation that reflects naturally occurring internal characteristics which are consistent with a natural ruby of this size and origin. The ruby has undergone heat treatment, a standard, widely accepted enhancement that improves color and clarity while remaining stable under normal wear conditions.

From a gemological perspective the most critical value attributes for rubies are color, clarity, carat weight, and origin. This specimen exhibits intense color intensity, which denotes strong saturation and a vivid red that reads as rich and lively under standard lighting. The cabochon cut is particularly effective at showcasing consistent body color across the stone, and it reduces the visual impact of internal growth structures that might be disruptive in a faceted stone. The slightly included clarity grade should be understood by an educated buyer as an indicator of natural formation rather than a detriment. In many rubies, especially those of larger dimensions, moderate internal features are expected, and they often serve as evidence of natural origin. Heat treatment is disclosed comprehensively, because our policy is full transparency, and buyers should note that heat treatment in rubies is routine and accepted in the trade, it typically improves color saturation and overall eye appeal without compromising structural stability.

The origin of this ruby is Mozambique, a source that has become significant in the modern ruby market. Mozambican rubies are known for producing vivid pinkish to purplish red material, and since the early 21st century Mozambique has supplied many of the gem quality larger rubies that collectors and high end jewelers prize. Origin contributes materially to value for many connoisseurs, because regional geology influences typical trace element chemistry and color profiles. A 16.56 carat ruby with intense saturation from Mozambique therefore occupies a unique position, it combines a desirable size with coloration that is consistent with market expectations for premium material. For investors and collectors who consider long term market dynamics, larger single stone rubies with documented provenance and disclosed treatments often command premium pricing, particularly when the gemstone exhibits superior polish and a clean, attractive surface.

At The Natural Ruby Company we emphasize accurate disclosure and service that supports confident purchasing decisions. We document carat weight, exact dimensions, shape, cut, clarity as evaluated at eye level, color intensity, polish grade, enhancement history as heat treated, and country of origin as Mozambique. For clients who require independent verification we offer assistance in arranging third party laboratory reports from recognized gemological laboratories. Practical guidance is also provided, for example the cabochon should be set to protect the dome from sharp impacts, classic bezel settings or secure halo mounts are recommended, and routine care consists of gentle cleaning with warm soapy water and a soft brush, avoiding aggressive chemicals and high impact, professional jewelers can advise on ultrasonic cleaning if desired, though heat treated rubies are generally stable under normal cleaning.
