7.54 Ct. Cabochon Turquoise from Persia(Iran)

I am pleased to present one beautiful, natural Persian turquoise from The Natural Gemstone Company, a piece that combines classic color and lapidary skill in a versatile size. This gem is a single opaque round cabochon, weighing 7.54 carats, with precise dimensions of 12.13 by 12.07 by 7.95 millimeters. The stone has been carefully shaped into a true round form with a high domed cabochon cut, producing a pleasing silhouette for both classic and contemporary settings. Color is a standout attribute on this specimen, described as a greenish blue with intense saturation that reads vividly across multiple light conditions, and the polish is excellent, delivering a smooth, reflective surface that enhances the stone s natural color and presence. Importantly, this turquoise is natural and untreated, with no enhancement, and its documented origin is Persia, Iran, a region renowned for producing some of the most sought after turquoise in the world.

Visually the cabochon presents a clean, even color field that emphasizes the richness of the greenish blue tone, the surface showing minimal visible matrix or veining which allows the color to command attention. The excellent polish yields bright, crisp reflections and a silky luster typical of well finished turquoise, making the dome appear luminous without any glassy or artificial sheen. The slight difference between the two diameter measurements, 12.13 and 12.07 millimeters, indicates a carefully measured cut that is essentially round and well suited to bezel or custom prong settings, and the height of 7.95 millimeters provides an attractive dome for three dimensional presence on rings or pendants. Photographs show the stone s uniform color and strong polish, and when set it will convey a timeless, refined look whether combined with warm or cool metal tones.

The Persian origin of this turquoise adds both historical context and collector appeal, Persia being celebrated for producing intensely colored turquoise for centuries, a gem that has been prized in jewelry and decorative arts. Because this turquoise has no enhancement, it retains the natural material s full character, which is important for collectors and discerning designers who value authenticity. From a design perspective, the stone s dimensions and cabochon profile make it versatile; consider a protective bezel setting to shield the graceful dome, or a custom high setting to showcase the height and play of light across the surface. Turquoise pairs beautifully with sterling silver for a classic, southwestern inspired aesthetic, and with yellow or rose gold for a warmer, more modern contrast that highlights the greenish undertones. The 7.54 carat weight makes it substantial enough to be a central stone for a cocktail ring or a striking pendant, while still being small enough to be comfortably wearable as an everyday piece.

To preserve the beauty and value of this untreated Persian turquoise, I recommend some simple care guidelines, as the natural, porous nature of turquoise means it can be sensitive to chemicals, cosmetics, and prolonged exposure to heat or direct sunlight. Store the piece separately from harder gemstones to avoid scratches, clean gently with a soft, dry cloth or a lightly damp cloth without soaps or ultrasonic cleaners, and avoid contact with perfumes, hairsprays, or household chemicals. If you plan to have the stone set into jewelry, discuss protective bezel designs with your jeweler, and consider a setting that minimizes exposure to knocks while still allowing the cabochon s color and polish to be admired. At The Natural Gemstone Company we stand behind the provenance and quality of this turquoise, and we are happy to provide additional photographs, angle shots, and measured reports upon request. This single, rich greenish blue Persian turquoise, with its excellent polish, intense color, and untreated status, is a rare find that will translate beautifully into a signature piece of jewelry or a discerning collector s cabinet, and we invite you to contact us to discuss purchase, custom setting options, or to ask any further questions.
