1.66 Ct. Multi Color Cabochon Black Opal (Dark Opal) from Australia

This exquisite Black Opal, Dark Opal, presented by The Natural Gemstone Company, is a translucent 1.66 carat oval cabochon with precise dimensions of 10.23 x 8.15 x 3.04 mm, exhibiting a classic dome and silhouette that maximizes play of color. As a cabochon cut, its polished domed surface has been shaped to reveal broad, dynamic flashes of green and blue against a darker body tone, a desirable combination for collectors and setmakers. From a grading perspective, note the key attributes, the body tone is dark which enhances the chromatic display, the transparency is translucent providing depth without sacrificing brightness, the color intensity is assessed as medium which yields persistent and attractive color without over saturation, the polish is excellent indicating meticulous lapidary work, and there is no enhancement which confirms the material is natural and untreated. Origin is Australia, the most respected source for quality black opals, and this provenance supports both the gemological characteristics and market value for an educated buyer seeking authenticity and provenance.

For the conscious consumer, this specimen aligns with ethical sourcing priorities, The Natural Gemstone Company maintains traceable procurement practices from mine to market, working with Australian suppliers who adhere to fair labor standards and environmental management practices, and the no enhancement status ensures the buyer receives a naturally occurring gemstone without stabilizing treatments or dyes. From an investment and curatorial standpoint, dark body tone black opals from Australia are comparatively rare and historically collectible, therefore a well cut, well polished translucent cabochon with intact natural play of color represents a strong choice for a collection focused on natural, responsibly sourced gemstones. Practical considerations include recommending a protective setting given opal hardness and internal structure, advising avoidance of harsh chemicals and extreme temperature changes, and suggesting routine cleaning with mild soap and water, followed by gentle drying. This piece is particularly suited for a pendant or low profile ring where the cabochon dome and play of color can be appreciated, and the documented origin, verified no treatments, and careful cutting and polish make it a credible, trusted acquisition for the knowledgeable buyer seeking both beauty and ethical assurance.
