3.57 Ct. Cabochon Turquoise from Persia(Iran)

This description details one natural, untreated Persian turquoise offered by The Natural Gemstone Company, presented for evaluation by jewelers, designers, and collectors. The gem is an opaque cabochon, oval in outline, weighing 3.57 carats, with dimensions of 11.08 x 9.12 x 4.32 mm. The cut is a traditional domed cabochon, executed to emphasize the stone color and surface luster, and the polish is described as excellent, producing a smooth reflective surface across the dome. Color intensity is strong and consistent, a clear blue that typifies high quality turquoise from Persia Iran, and the piece exhibits no visible matrix or veining in the provided images. Enhancement status is none, the stone has not been stabilized, dyed, or otherwise treated, and the provenance is recorded as Persia Iran, a region historically recognized for producing desirable turquoise with distinctive hue characteristics.

From a gemological perspective, the opacity and cabochon form are well suited to turquoise, a hydrated phosphate mineral that is typically presented as a solid, non transparent gem. The cabochon shape concentrates the perceived depth of color, allowing the blue to appear even and saturated under a variety of light sources. The absence of enhancements means the color and surface condition reflect natural material properties, including any minor surface variation or small inclusions inherent to turquoise. The reported dimensions and carat weight indicate a well proportioned gem for small to medium sized rings, pendants, or custom inlay work, and the moderate dome height contributes to wearability while maintaining a pleasing profile for bezel settings. The turquoise is sufficiently substantial to be securely set without extensive backing or reinforcement in most traditional jewelry mountings.

The cutting and finishing of this cabochon reflect attention to symmetry and surface integrity, important factors when evaluating a gem for professional settings. The oval outline measures just over eleven millimeters on the long axis and just over nine millimeters on the short axis, providing an elongated appearance that is often favored for solitaire rings and vertical pendant motifs. The rise of 4.32 millimeters gives the cabochon a noticeable dome that enhances light reflection and color saturation, while the uniform polish minimizes microabrasions that can detract from visual clarity. Edge finishing and girdle curvature have been managed to facilitate secure bezel seating, and the overall proportions suggest the cabochon was shaped to balance visual presence with practical mounting considerations. For designers, the piece offers predictable behavior during fabrication, and for collectors, the combination of weight, dimensions, and natural origin make it a representative example of classic Persian turquoise.

The Natural Gemstone Company provides this gem with documentation of origin and treatment status to support informed purchasing decisions. Given the natural and untreated condition, standard care recommendations apply, including avoiding prolonged exposure to oils, cosmetics, or household chemicals, cleaning with a soft, dry cloth, and storing separately to prevent abrasion from harder gemstones or metals. The stone is suitable for everyday wearable pieces, provided settings offer reasonable protection from hard knocks and abrasive surfaces, and when used in designs that minimize direct impact it will maintain its polish and color over time.
