2.63 Ct. Greenish Blue Cabochon Turquoise from Persia(Iran)

This exceptional Persian turquoise offered by The Natural Gemstone Company is a fine example of classic old world material, presented as an opaque, greenish blue oval cabochon weighing 2.63 carat, with dimensions of 8.54 by 7.69 by 5.60 mm. The cutting style is cabochon, which is traditional for turquoise and ideal for showing off its uniform color and surface polish. The color intensity is medium, with a soothing balance between blue and subtle green undertones that give the stone a natural, organic character. The piece is untreated, with no enhancement, which is a key attribute for both collectors and educated buyers who understand that natural Persian turquoise in an unenhanced state is rare and historically desirable. The provenance of Persia, Iran, carries a heritage value, since Persian turquoise has been prized for centuries for its stable, often matrix free blue tones that were favored in classical and court jewelry across many cultures.

From a grading and clarity perspective, this cabochon displays what specialists describe as a clean, semi uniform body color with minimal visible veining or matrix interference in the photos, which enhances its appeal and market grade. Turquoise does not grade on clarity in the same way as transparent gems, rather the evaluation focuses on color uniformity, matrix presence, porosity, and any signs of stabilization or dye. The medium color intensity of this piece sits in an optimal zone where the hue remains vivid without appearing artificial, and the excellent polish on the dome gives the surface a smooth, satiny shine that emphasizes color saturation. The cabochon cut and domed profile concentrate surface reflectance into broad, soft highlights rather than faceted scintillation, allowing the eye to appreciate the stone as a coherent, painterly field of color. The dimensions of 8.54 by 7.69 by 5.60 mm make it very practical for a ring or pendant, offering presence without overwhelming proportion, and the weight of 2.63 carat confirms a substantial material density consistent with compact, quality turquoise.

When comparing reflective qualities, it is important to place turquoise in the correct optical family. Turquoise typically exhibits a waxy to subvitreous luster, and this piece is a fine representation of that finish due to the excellent polish. The reflection you see on a turquoise cabochon is broad and soft, a single larger specular highlight that follows the dome, as opposed to the multitude of small flashes produced by faceted gems such as sapphires or emeralds. Compared to other opaque gems in its category, such as lapis lazuli, chrysoprase, and variscite, Persian turquoise tends to present a cleaner, less granular reflection because high quality turquoise often lacks the noticeable inclusions and pyritic specks that give lapis its metallic flecking. Chrysoprase can appear more waxy and occasionally slightly translucent at the edges, creating a deeper glow, whereas variscite is often softer in color and slightly less reflective. Within turquoise origins, American materials like Sleeping Beauty are celebrated for their pure sky blue and even tone, but many of those pieces have been stabilized or treated to increase durability, which can alter surface response. This Persian cabochon, being natural and untreated, shows a more authentic, softer luster that collectors value for its unmodified appearance. The absence of enhancement means the surface reflections are solely a product of the natural structure and high quality polish, rather than surface oils or resins that can sometimes create an unnaturally glossy look in stabilized stones.

For the educated buyer assessing value, several factors converge to make this turquoise noteworthy. The origin, Persia, Iran, confers historical and aesthetic premium due to a long standing reputation for producing robin egg to greenish blue material with attractive uniformity. The lack of enhancement is a major differentiator in the market, because much of the commercial turquoise trade includes stabilization, dyeing, or reconstitution, all of which reduce a stone's collector grade and long term value. The cabochon cut and excellent polish maximize color presentation and wearability, and the medium intensity ensures versatility across jewelry styles. In terms of practical considerations, turquoise rates approximately five to six on the Mohs hardness scale, which means it requires some care, especially in rings that receive daily wear. Setting recommendations include protective bezel settings or partial bezels that shield the cabochon rim, and avoiding exposure to household chemicals, extreme heat, or prolonged moisture to keep the untreated surface in its original condition. For buyers seeking a piece that combines historical provenance, natural authenticity, and pleasing aesthetic performance, this stone represents a strong proposition, and The Natural Gemstone Company can provide provenance documentation and individualized advice on mounting and care to preserve its value.

In summary, this 2.63 carat Persian turquoise cabochon, measuring 8.54 by 7.69 by 5.60 mm, offers a classic combination of gently greenish blue hue, medium color intensity, excellent polish, and the rare advantage of no enhancement. Its reflective quality is characteristic of high grade cabochon turquoise, delivering broad, soft highlights rather than faceted brilliance, and it compares favorably against both other turquoise origins and similarly opaque colored stones from a collector and design perspective. Buyers who prioritize authenticity, provenance, and wearable beauty will find this specimen compelling, and as representatives of The Natural Gemstone Company we are available to discuss how this cabochon will set and wear over time, and to arrange secure delivery and certification for your peace of mind.
