2.63 Ct. Cabochon Turquoise from Persia(Iran)

The Natural Gemstone Company presents a fine example of classic Persian turquoise, an opaque cabochon weighing 2.63 carat, with precise dimensions of 8.54 by 7.69 by 5.60 mm. Cut as an oval cabochon, the piece exhibits an expertly controlled dome profile, with a calibrated height that balances visual presence with wearability. The cutter maintained strict symmetry along both major and minor axes to preserve even light return across the dome, resulting in a single broad highlight and a soft, satiny luster. The excellent polish is evident in the uniform specular reflections and the absence of surface pits or lapping marks, indicating that the final stages of polishing were executed with fine abrasives and a high quality polishing compound. The stone is uniformly opaque, demonstrating minimal internal fracturing and no visible hairlines under standard loupe inspection, which is notable for untreated material from this origin.

Color is the defining characteristic of this specimen, an intense greenish blue that is emblematic of the most desirable Persian turquoise color range. The saturation is high, with chroma concentrated toward the midtone, producing a vivid yet natural appearance that reads cleanly against both light and dark settings. The hue balance favors a cool greenish blue rather than a pure sky blue, offering depth without veering into artificial tones. Color distribution is notably even across the table and girdle, with only faint tonal nuances that add visual interest without appearing as undesirable mottling. The absence of visible matrix, veining, or dark inclusions enhances the perception of a solid color field, making this cabochon particularly suitable for boutique and high end applications where color purity is paramount. Origin is Persia, Iran, a provenance associated with historically prized material, and the stone is offered with full disclosure of no enhancement, confirming that no stabilization, dyeing, or resin impregnation has been applied.

From a lapidary and setting perspective, the dimensions and dome profile make this cabochon highly versatile. The thickness of 5.60 mm provides structural integrity for bezel and flush mount settings, while the even oval outline allows for precision tension or prong design if the jeweler prefers an elevated presentation. Given the natural, untreated nature of the turquoise, recommended mounting practices favor protective bezel settings or halos that reduce exposure to knocks and abrasion. Chemical and thermal sensitivity are considerations for natural turquoise, therefore avoiding ultrasonic cleaning and steam cleaning is prudent, and exposure to acidic substances, perfumes, and prolonged sunlight should be minimized to preserve color. Cleaning with a soft cloth and mild, pH neutral soap and water is advised, followed by immediate drying. For collectors and designers who appreciate provenance and craftsmanship, this cabochon presents an authentic Persian aesthetic combined with meticulous cutting and polishing standards.
