2.96 Ct. Cabochon Turquoise from Persia(Iran)

This listing from The Natural Gemstone Company presents a single, meticulously prepared turquoise specimen weighing 2.96 carats, in a round outline with calibrated dimensions of 8.06 by 8.10 by 6.93 millimeters, origin Persia, Iran, and no enhancement. The piece is opaque in body color, displaying a true bluish green hue with intense saturation, and has been fashioned into a traditional cabochon profile. The cutter has prioritized a high domed silhouette, producing a pronounced convex plane that optimizes color depth and light play across the surface. The absence of any treatment, including stabilization, dyeing, or resin impregnation, is confirmed, so the visual character derives wholly from the native turquoise matrix and its original crystallographic texture. For connoisseurs of natural material, this combination of provenance, intact physicality, and uncompromised surface quality makes the specimen a desirable example of Persian turquoise as offered by The Natural Gemstone Company.

From a lapidary perspective the piece exhibits classic cabochon execution, with continuous curvature from girdle to apex, and exceptional symmetry in the circular outline. The measurements indicate a relatively high crown ratio, with the height approaching the radius, yielding a substantial dome that enhances the perceived volume of color. The cutter maintained even thickness across the pavilion which contributes to stable mounting and reduces the risk of breakage when setting. The base appears to have been leveled to a discrete flatness sufficient for secure bezel seating, while still preserving enough depth to respect the material strength of turquoise, which typically registers around 5 to 6 on the Mohs scale. Edge rounding is controlled to prevent sharp girdles that can chip, and the profile transition from sidewall to crown is smooth, indicative of fine sanding sequences culminating in a final polish stage that removed microabrasions without overworking the surface.

Optical and material characteristics are notable, the turquoise shows intense, saturated bluish green with a slight leaning toward the greener spectrum, producing a lively yet deep tone under standard viewing conditions. The opacity is uniform, with negligible translucency at the thinnest edges, and there is no visible webbing or contrasting matrix that can interrupt color homogeneity. The polish is excellent, providing a glassy, near specular finish which enhances specular highlights and emphasizes the dome curvature. This high polish also aids in assessing surface integrity, and under magnification the surface presents minimal undulations and an absence of filler related flash or localized seaming. Specific gravity for turquoise generally lies between 2.6 and 2.9, and refractive indices near 1.61 to 1.65, values that align with expectations for natural, unenhanced material and confirm the handling characteristics for setting and repair work.

For practical application and design integration the substantial dome and intense color make this cabochon particularly well suited to gallery settings, high bezel walls, and pendant focal points where the profile can be appreciated in three dimensions. In ring applications a secure bezel setting with sufficient seat depth is advised to protect the higher crown, and the cutter has left adequate pavilion depth to allow for such secure bezel construction. Given turquoise sensitivity to acids, oils, and prolonged exposure to humidity variations, routine care protocols include limiting contact with chemicals and cosmetics, and avoiding ultrasonic cleaning. As a natural, untreated Persian turquoise, this piece carries both aesthetic and collector value, and The Natural Gemstone Company stands behind its provenance and crytallographic authenticity, offering additional documentation upon request.
