5.75 Ct. Blue Cabochon Turquoise from USA

This pear shaped cabochon turquoise presents as a beautiful, opaque 5.75 carat stone, measuring 16.34 x 10.87 x 4.81 mm, with an intense blue color and an excellent polish. From a grading perspective, color intensity and uniformity are primary determinants of value for turquoise, and this piece displays a vivid, even sky blue tone that is highly sought after by collectors and designers. Clarity in turquoise is described differently than in transparent gems, focusing on matrix patterns, veining, and porosity rather than internal transparency. Under magnification this cabochon shows minimal dark veining and low apparent porosity, which combined with the high polish produces a smooth, reflective surface ideal for both statement pendants and fine ring settings. Importantly, this turquoise has no enhancement, no stabilization, and no dye, a condition that significantly elevates its market value because most commercial turquoise is treated to improve color and durability. The origin is the USA, which for educated buyers often implies access to well documented mines and a historical preference for uniform, natural blue material.

For practical and investment considerations, untreated US turquoise with intense natural color is relatively scarce, and this specimen offers a compelling balance between aesthetic appeal and gemological integrity. On the Mohs scale turquoise typically registers around 5 to 6, so care and protective mounting are advisable, especially for ring use. Bezel settings, protective halo designs, and pendants are recommended to reduce impact risk and prevent exposure to household chemicals, cosmetics, and prolonged direct sunlight, which can alter surface appearance over time. Cleaning should be limited to a soft cloth and mild soapy water, avoiding ultrasonic and steam cleaners. At The Natural Gemstone Company we document origin and treatment status, and we welcome requests for detailed imagery and magnified views for appraisal purposes. For designers and collectors seeking an authentic, untreated American turquoise with consistent color, fine polish, and a classic pear cabochon silhouette, this stone represents an enduring choice that blends aesthetic distinction with provenance and gemological credibility.
