2.25 Ct. Ruby from Tanzania

This transparent 2.25 carat oval ruby, measuring 7.21 x 6.70 x 5.19 mm, is a refined example of Tanzanian corundum, offered by The Natural Ruby Company, and it stands out immediately for its balance of weight, proportions, and optical performance. The gem has been fashioned in an oval shape with a mixed brilliant cut, a choice that combines a faceted pavilion designed for depth with a crown arrangement that encourages lively scintillation, and the result is a face up presentation that captures light while maintaining a deep, concentrated color. Clarity is graded as very slightly included at eye level, which means that under normal unaided viewing the stone appears clean, with only minor internal characteristics visible under magnification, a clarity class that preserves transparency and maximizes light transmission. Color assessment records intense color intensity with an excellent polish, and critically this ruby is untreated, no enhancement, which is an important distinguishing factor for buyers who value natural state gemstones and provenance. The dimensions translate to a comfortable presence in most settings, allowing the gem to read as a substantial and wearable 2.25 carat ruby, and its corundum hardness and robust polish make it durable enough for rings that will see frequent wear.

When evaluating hue and tone, this Tanzanian ruby exhibits a warm, saturated red with a slight brownish overtone in certain lighting, and a deeper pure red in stronger, direct illumination, a characteristic interplay that creates both richness and versatility. Compared to classic Burmese rubies, which are prized for their vivid, pigeon blood red leaning slightly to pure red with a subtle blue undertone, this Tanzanian example is less overtly blue and carries a warmer, earthier nuance that some connoisseurs prefer for its depth and vintage character. Against Mozambique stones, which often show a high saturation and can lean toward a bright, almost tomato like red or purplish red depending on deposit, the Tanzanian ruby here is more restrained and refined, offering intense saturation without verging into overly vivid or neon territory. Compared to Thai or Cambodian rubies that can display a darker, more brownish red tone, this gem retains a higher degree of brightness and clarity, with superior light return from its mixed brilliant cut, which keeps the overall tone lively rather than somber. Madagascar stones often present a pinkish to purplish inclination, and by contrast this Tanzanian ruby remains firmly in the red spectrum with limited pink or purple modifiers, making it especially appealing to buyers seeking a classic red ruby that is natural and untreated.

For the educated buyer assessing value, several factors elevate this stone beyond mere esthetic appeal, and The Natural Ruby Company highlights these attributes for clear decision making. The combination of an over two carat weight, eye level very slightly included clarity, intense color intensity, and the absence of any heat or dye enhancement results in a rare offering, since many rubies in the market are subjected to heat treatment to improve color and clarity. Untreated rubies of this quality and size, with documented Tanzanian origin, generally command a premium because they preserve the natural geological story and avoid artificial modification. The mixed brilliant cut and excellent polish are functional as well as aesthetic, as they maximize brilliance and contribute to consistent light return, which enhances apparent saturation without artificially altering the hue. From a practical perspective the dimensions allow for a range of classic and modern settings, central solitaire rings, halo settings that emphasize color by contrast, and pendants where the oval outline and depth will create pleasing light play. We recommend considering a fine setting that allows light to interact with the pavilion, and we advise routine care consistent with corundum, gentle cleaning with warm soapy water, and avoidance of harsh chemicals. The Natural Ruby Company can assist with documentation and photography to support appraisal and insurance, and we welcome inquiries for additional images under various lighting conditions, or for discussion regarding bespoke mounting options, as transparency about origin, clarity, and treatment is central to our approach and to the long term satisfaction of the buyer.
