One beautiful opaque 1.30 carat oval shape greenish blue turquoise is presented by The Natural Gemstone Company, a gem that measures 10.15 by 8.14 by 3.87 millimeters, with a classic cabochon cut, vivid color intensity, and an excellent polish. This piece is unenhanced, and its origin is Persia, Iran, a region historically and presently esteemed for producing some of the finest turquoise in the world. The oval cabochon has been shaped to maximize face up presence, giving a substantial visual size relative to its carat weight, and the even domed profile highlights the saturation and tone of the greenish blue color. As a natural, opaque turquoise, this gem displays the creamy, evenly distributed color that collectors and designers value for both aesthetic and durable wearable qualities.
From a grading perspective, several key attributes define the desirability of this stone, starting with color, followed by clarity, cut, and condition. The color is the most important single attribute in turquoise, and this specimen shows a vivid greenish blue that balances blue vibrancy with a subtle green note. This balance is particularly prized in Persian turquoise, where a slightly greener hue can indicate specific copper to aluminum ratios in the material, and can appeal to buyers seeking a lively yet sophisticated color. Clarity in turquoise is evaluated differently than in transparent gems, with emphasis on opacity, presence or absence of matrix, and the visual cleanliness of the surface. This cabochon is described as opaque with a clean appearance, and any natural inclusions are subtle and consistent with untreated turquoise from primary Persian deposits. The cabochon cut is well executed, with a smooth, symmetrical dome and excellent polish that enhances luster and color saturation. The dimensions and depth are practical for bezel and prong settings, and the weight to size ratio is appropriate for the stated carat weight, indicating careful cutting to preserve color and stability.
Equally significant to educated buyers is the treatment history, and this turquoise is documented as having no enhancement, which materially affects value and long term behavior. Many commercial turquoise pieces are stabilized with resins, dyes, or resin impregnation to improve hardness and color uniformity, and these treatments can alter care recommendations and long term patina. An untreated stone, like this Persian turquoise, retains its natural porosity and tactile qualities, and it is valued both for authenticity and for the unique way it ages with wear. Buyers should be informed that untreated turquoise, while beautiful and desirable, benefits from mindful care, avoiding prolonged exposure to acids, perfumes, lotions, and household chemicals, and avoiding ultrasonic cleaners and harsh steam cleaning. Setting recommendations include protective bezel settings or designs that limit direct exposure to knocks, since natural turquoise is softer than many other gem materials, but the excellent polish and solid dome of this cabochon contribute to wearability for rings, pendants, and bespoke jewelry pieces.
For the educated buyer or collector, provenance, natural state, and aesthetic quality combine to create lasting value, and this Persian turquoise embodies all three attributes. Persia, Iran has a long recorded provenance for turquoise, with mines that have supplied top quality material for centuries, and the name Persian or Iranian turquoise carries market premium when the stone is natural and unenhanced. The Natural Gemstone Company stands behind the sourcing of this item, and we can provide detailed notes on origin and treatment status to support appraisal and resale. In design terms, the vivid greenish blue color makes this cabochon versatile for period inspired settings, modern minimalist mounts, or high contrast designs with metals such as yellow gold or warm rose gold. For investors, natural, untreated turquoise with documented origin is a piece that retains collector interest, as high quality Persian material becomes less common on the open market, and as demand for natural colored stones continues to grow among connoisseurs. If you would like additional measurements, mounting recommendations, or photographic angles for design planning, The Natural Gemstone Company is available to assist, and we offer optional independent certification and custom setting services to ensure your purchase meets exacting standards for both beauty and authenticity.
