15.79 Ct. Cabochon Turquoise from Persia(Iran)

This listing presents a single, beautiful, opaque turquoise cabochon offered by The Natural Gemstone Company, weighing 15.79 carats, with a classic round shape and proportions measuring 16.08 by 15.85 by 10.44 millimeters. The stone displays a greenish blue hue with medium light color intensity, a smooth high dome characteristic of a fine cabochon cut, and an excellent polish that delivers a pleasing, satiny reflection across the surface. The material is untreated, no enhancement, and originates from Persia, Iran, a region historically celebrated for its high quality blue turquoise. Visually the cabochon shows a uniform color field with subtle natural veining and minimal surface irregularities, confirming its opaque classification and reinforcing its desirability for both collectors and designers looking for an authentic Persian turquoise specimen.

From a gemological perspective this turquoise scores strongly on the standard criteria that informed buyers prioritize. Color is the primary determinant of market value in turquoise, and this piece sits in the sought after greenish blue range with even color distribution, which is prized for balancing classical robin egg blue tendencies with a touch of green that enhances versatility in design. Clarity in turquoise relates to the density of matrix and the presence of fractures or voids. This cabochon shows minor natural matrix veining and no evidence of filling or resin stabilization, which preserves the natural texture and patina collectors value. The cabochon cut is expertly executed, providing a pleasing dome height that maximizes color depth and surface lustre, while the excellent polish contributes to wearability and visual appeal. The weight of 15.79 carats and the substantial millimeter dimensions make this stone notably larger than typical turquoise used in rings, making it ideal for statement pendants, brooches, or custom pieces where the origin and natural state can be fully appreciated. The Persian provenance is especially relevant to an educated buyer, because historically mined Persian turquoise has commanded premium prices due to its consistency, color, and cultural significance in the international gemstone market.

For practical use and long term value considerations, turquoise requires informed care because of its physical properties. Turquoise generally rates around a five to six on the Mohs hardness scale, so it benefits from protective settings that reduce impact and abrasion. Avoid prolonged exposure to chemicals, cosmetics, and household cleaners, and remove jewelry during strenuous activities to maintain polish and color. For jewelry settings consider bezel mounting or protective prongs and integrate with metals that complement the greenish blue tone, such as warm yellow gold for contrast, or matte silver for a vintage aesthetic. At The Natural Gemstone Company we emphasise provenance, transparent grading, and ethical sourcing, and we can provide additional services such as custom cutting, matching pairs where possible, certified documentation of origin and treatment status, and high resolution imaging for client review. This 15.79 carat Persian turquoise is a rare, untreated natural specimen that will appeal to collectors, designers, and discerning buyers who understand the premium placed on natural color uniformity, classic origin, and substantial size.
