9.36 Ct. Cabochon Turquoise from Persia(Iran)

This piece is a single, opaque, oval shaped turquoise weighing 9.36 carats, with precise dimensions of 17.94 by 13.15 by 5.35 millimeters. The gem has been fashioned as a cabochon, exhibiting a well controlled domed profile and a uniform outline, reflecting careful preforming and lapidary execution. The cabochon dome presents a moderate to high rise relative to its length, with a dome to length ratio of approximately 0.30, a proportion that maximizes color saturation while retaining comfortable wearability in a variety of mounting styles. Edge symmetry is excellent, with a consistent girdle flow that allows for secure bezel seating, and the base plane is flat enough to ensure stability in both bezel and closed back mountings. Polishing has been executed to a very high standard, producing a bright, glass like surface luster that highlights the stone body color and masks minimal surface texture, indicating meticulous final finishing and polishing sequences on progressively finer abrasives.

Color characteristics are of primary importance for turquoise, and this specimen displays an intense blue hue with strong saturation and an even tonal distribution across the table and dome sides. The color is vivid and leans toward a classic Persian blue, a hue historically prized for its clarity and depth, and consistent with material originating from Persia Iran. The turquoise is opaque, without translucent windows, which is typical for high quality Persian material and advantageous for settings that require a bold color statement. There is negligible visible matrix or veining in this example, allowing the color plane to read as a continuous field, which increases versatility for designers seeking a monochromatic presence. No enhancement has been applied to this stone, it is offered untreated, and this natural state preserves original porosity and surface characteristics, which is a key factor for collectors and connoisseurs. From a color grade perspective, the piece would be described as intense, with minimal zonation and no apparent patchy areas, a result of consistent mineral deposition and careful selection by our sourcing team.

Practical considerations for use, maintenance, and setting are informed by the gemological attributes of turquoise and the fine craftsmanship evident in this cabochon. With a thickness of 5.35 millimeters and excellent polish, the cabochon benefits from protective settings, with bezel mountings being the preferred option to safeguard the high domed surface and reduce exposure to impact and abrasive wear. Open back settings may be used for design reasons, however buyers should be aware that untreated turquoise can be relatively porous compared to many gemstones, and care should be taken to avoid strong solvents and extended immersion in water, which can affect surface oils and finish over time. When integrating into jewelry, metals with a slightly raised bezel profile will protect the dome edge without visually overwhelming the stone, and custom gold or silver mounts can be designed to accentuate the Persian blue while providing long term mechanical security. The Natural Gemstone Company sources and inspects each piece under controlled lighting and standardized measurements, and we can provide detailed imaging and condition reports upon request, including suggestions for setting dimensions and recommended protective treatments that do not alter the stone integrity. For collectors seeking authentic, untreated Persian turquoise in a well executed cabochon, this 9.36 carat oval represents a combination of excellent color intensity, precise lapidary technique, and responsible provenance.
