1.72 Ct. Blue Cabochon Turquoise from Persia(Iran)

This listing from The Natural Gemstone Company presents a beautiful, classic oval cabochon turquoise, precisely 1.72 carat in weight, with exact dimensions of 9.33 by 6.88 by 3.89 millimeters. The cutting style is traditional cabochon, the color is a clear medium blue with even saturation, the surface finish shows an excellent polish, and importantly there has been no enhancement to alter the stone. The material is opaque turquoise of Persian origin, Persia, Iran, a source long associated with fine robin egg and sky blue material that commands attention in both historical collections and contemporary design. From a grading perspective the most relevant points for an educated buyer are uniform body color, stable opacity, and surface quality, all of which are evident in this example. The clarity is appropriate for turquoise in that the stone is opaque and exhibits minimal matrix or veining, producing a smooth, homogenous appearance that emphasizes color rather than internal pattern. Because the stone has not been treated, its medium color intensity and natural polish reflect the genuine character of Persian turquoise, making it a reliable choice for buyers who prioritize untreated material and documented origin.

The cabochon cut is particularly well suited to turquoise, and in this piece the dome and symmetry have been executed to optimize the stone is interaction with light. A cabochon does not rely on faceting to generate brilliance, instead the domed surface and excellent polish produce controlled specular highlights and a soft inner glow that enhance perceived color saturation. In practical terms the curved profile allows incident light to travel a short distance through the surface layers and reflect back with minimal scattering, which is critical for an opaque mineral where internal transparency is limited. The oval outline provides a balanced optical return over the length of the stone, and the measured height of 3.89 millimeters yields enough dome to create visible highlight spots without flattening the appearance. The excellent polish reduces surface micro irregularities, increasing the sharpness of reflections and giving the cabochon a lively, wet look that is highly desirable in turquoise. For designers and setters the result is predictable, with consistent luster under varied lighting and a surface that photographs well, which helps preserve color fidelity in both museum lighting and everyday wear.

For the informed collector or jewelry professional the combination of Persian provenance, natural condition, attractive medium blue hue, and careful cabochon work positions this turquoise as an enduring and versatile choice. Persian turquoise is historically prized for its stable, vivid blues, and an untreated piece of this size, weight, and finish offers both aesthetic appeal and provenance value. The oval shape at just over nine by six millimeters is an excellent size for center stones in classic ring settings, for elegant pendants, or for refined inlay work in bespoke pieces. Because turquoise is comparatively soft relative to corundum or diamond, setting recommendations for long term wear include protective bezel mounting and avoidance of exposure to harsh chemicals and prolonged moisture, measures that will preserve the excellent polish and the natural surface. From an investment and design standpoint buyers benefit from the transparency about enhancement status, the precise measurements and weight, and the documented Persian origin, all factors that support confident acquisition and future resale. The Natural Gemstone Company stands behind the factual description of this cabochon, and the stone is presented as a ready to set, untreated, museum quality example of Persian turquoise that will perform beautifully in jewelry while retaining the natural character that educated buyers value.
