2.91 Ct. Cabochon Turquoise from Persia(Iran)

This is a fine example of natural Persian turquoise offered by The Natural Gemstone Company, a 2.91 carat oval cabochon with dimensions of 10.84 by 8.65 by 4.58 mm. The stone presents an even bluish green hue with intense color saturation, and it is uniformly opaque, which is typical of higher grade Persian material. The cabochon cut has been executed to produce a smooth dome and excellent polish, enhancing surface luster and the stone s apparent depth. Clarity in turquoise is assessed differently from transparent gems, and in this specimen the absence of prominent matrix veins or visible fractures contributes to a clean appearance, which increases desirability. No enhancement has been applied, a significant factor for the educated buyer, because untreated Persian turquoise is substantially rarer and commands a premium over stabilized or dyed material. The natural origin, Persia, Iran, is historically respected for producing some of the most sought after turquoise, particularly for its stable mineral composition and characteristic robin s egg to bluish green tones. Measurements and carat weight are precise, and the proportions make this gem well suited for classic ring and pendant settings that protect the stone while showing off its color.

From a valuation perspective, several attributes make this turquoise valuable to an informed collector or jeweler. Color intensity and uniformity are primary determinants of market value, and this cabochon exhibits both, offering consistent saturation across the surface. The absence of treatment is a major positive, because enhancements such as stabilization, dyeing, or reconstitution alter both the material properties and market classification. The cut and polish are important for both aesthetic and practical reasons, and an excellent polish combined with a well formed dome improves perceived size and wearability. Persian provenance enhances provenance documentation and market confidence, since origin often correlates with expected material characteristics and historical desirability. Care recommendations for untreated turquoise include avoiding prolonged exposure to chemicals, cosmetics, and extreme heat, and setting designs that protect the girdle and dome will prolong the stone s appearance. The Natural Gemstone Company stands behind the authenticity of this piece, and we can supply additional imagery and measurement confirmation on request. This turquoise represents a classic, collectible example for those seeking a natural, untreated Persian gem with strong color and solid lapidary workmanship.
