4.60 Ct. Cabochon Turquoise from Persia(Iran)

This is a finely proportioned, opaque 4.60 carat round turquoise, with dimensions of 10.17 by 10.14 by 6.56 mm, presented as a classical cabochon cut with an excellent polish. The color registers as bluish green with medium intensity, offering a pleasing balance between blue and green tones that is often sought after by collectors and designers seeking versatility. From a gemological perspective the cabochon shape emphasizes the stone s body color and surface texture, and the excellent polish enhances luster while minimizing light scattering from the surface. Clarity in turquoise is described differently than in transparent gems, and this piece shows the typical fine, opaque structure of natural turquoise rather than fractures or internal inclusions that affect clarity grades in transparent stones. The absence of enhancement is a significant attribute, meaning this specimen has not been stabilized, dyed, or reconstituted, all treatments that can alter appearance and market value. For an educated buyer the combination of natural state, uniform medium color intensity, and careful cutting provides a reliable basis for valuation, as untreated Persian turquoise commands a premium relative to treated material.

Origin is a defining factor in turquoise valuation, and this stone s reported source, Persia, Iran, carries historical and market significance. Persian turquoise has been prized for centuries for its stability of color and fine texture, and even when the hue shifts toward bluish green rather than the pure robin s egg blue, provenience contributes to desirability and potential investment value. The gem s weight and nearly equal diameter proportions make it well suited for center stones in bespoke rings or as a prominent element in classic cabochon settings, where its opacity and polish will read consistently under different lighting conditions. Buyers should note that turquoise is relatively soft compared with many gemstones, and appropriate protective settings and routine care will preserve surface polish and prevent wear. At The Natural Gemstone Company we stand behind the provenance and untreated status of this turquoise, and we can provide additional images, magnified views, and handling advice to assist in mounting and long term care. For collectors and jewelers seeking an authentic Persian turquoise with natural character, stable coloring, and no enhancements, this 4.60 carat cabochon represents a sound and attractive choice.
