20.46 Ct.Tw.Total Carat Weight Cabochon Turquoise Pair from Persia(Iran)

This matched pair of Persian turquoise cabochons offered by The Natural Gemstone Company presents a rare combination of size, color, and natural integrity that will appeal to collectors and discerning jewelers. Each stone weighs 10.23 carats, with the first measuring 17.80 x 13.06 x 6.10 mm and the second measuring 17.65 x 12.77 x 6.36 mm. Both are oval shaped and cut en cabochon to maximize the perceptible depth of color and surface sheen. The stones are opaque, displaying a vivid color intensity described by connoisseurs as a pure sky to robin egg blue, and they exhibit an excellent polish that gives a clean, glossy surface without visible frosting or dull areas. Importantly, these turquoises have no enhancement, which means they have not been stabilized, dyed, or impregnated, and their visual character is entirely natural and intrinsic to the material as mined in Persia, Iran.

When evaluating turquoise quality it is customary to focus on color, clarity including matrix or host rock, cut and polish, and treatment status. Color is the single most influential factor for value in blue turquoise. The vivid, evenly saturated blue in these stones is particularly desirable because it is uniform across the face of each cabochon, without mottling or dominant brown matrix, which many buyers seek to avoid for a pure blue aesthetic. Clarity in turquoise is normally expressed as degree of openness to matrix and porosity rather than gemstone transparency. These specimens are opaque yet dense and homogenous at the surface, indicating a high degree of structural integrity and low porosity, which contributes to durability. The cabochon cut is the traditional and most flattering cut for turquoise because it presents the color uninterrupted by facets, while the excellent polish achieved here enhances luster and perceived depth, factors that experienced buyers and setters use to assess desirability. The fact that these gems are natural and untreated places them in a premium category, because many commercial turquoises are stabilized with resins or enhanced to improve color consistency and durability.

From the standpoint of practical use and long term value the pairing, weight, and dimensions make these stones ideal for matched earrings, a pendant duo, or as focal elements in a bespoke jewelry commission. A matched pair of 10.23 carat cabochons offers symmetry and presence, while the dimensions allow for comfortable and elegant mounting without excessive bezel work. Persian turquoise has a classical provenance that carries cultural and market cachet. Historically esteemed for its striking blue hues and longstanding artistic associations, Persian material remains sought after by collectors who value provenance as part of gemstone narrative. For the educated buyer, the combination of origin, untreated status, consistent and vivid color, and quality of cut and polish are the primary drivers of both immediate aesthetic appeal and long term investment potential. Practical care advice for natural turquoise includes avoiding prolonged exposure to solvents, oils, and strong acids, minimizing contact with cosmetics and household cleaners, and choosing secure settings that protect the stone from sharp knocks.
