3.29 Ct. Multi Color Black Opal (Dark Opal) from Australia

This Black Opal, also called Dark Opal, from The Natural Gemstone Company is a beautifully translucent, multi color specimen weighing 3.29 carat and measuring 13.27 by 9.58 by 3.72 millimeters. The stone is fashioned in an oval tablet cut that emphasizes broad, vibrant flashes of color across the surface. The tablet cutting style creates a shallow profile that is ideal for dark opal material because it allows the internal play of color to present with maximum intensity against the stone body, while preserving weight for collectors who value both visual impact and substance. This particular gem exhibits intense color intensity with a vivid spectrum of blues and greens and occasional warm flashes, an excellent polish that produces a clean, reflective surface, and a clarity grade of slightly included when evaluated at eye level. There has been no enhancement applied to this opal, which means the color, translucency, and internal structure are entirely natural, and the documented origin is Australia, the world renowned source for high quality black opal material.

For the educated buyer, understanding the grading and morphology of this opal clarifies its value and suitability for a refined collection. Carat weight is a standard metric for size and market value, and at 3.29 carat this tablet cut oval sits in a range that is significant without being excessively large, making it versatile for both high end custom jewelry and cabinet quality collections. Dimensions are important for setting design, and the 13.27 by 9.58 by 3.72 millimeter proportions offer a comfortable balance between surface area and depth, enhancing the stone’s visible play of color. The clarity grade of slightly included indicates the presence of minor internal features that are visible at the naked eye but do not interrupt the overall visual performance. In opal grading, slight inclusions are common and often acceptable, particularly when the piece demonstrates strong, uninterrupted color play and a stable structure, as this specimen does. The intense color intensity and excellent polish raise the aesthetic grade considerably, because rich, saturated flashes and a smooth reflective surface are primary drivers of desirability and market value in black opal. The tablet cut is a deliberate choice for this material, designed to present large, ribbon like color fields rather than the small mosaic patterns seen in other cuts, an attribute that many connoisseurs prefer for display pieces or elegant, modern jewelry designs.

Ethical sourcing is central to why this opal is attractive to the conscious consumer, and The Natural Gemstone Company emphasizes traceability and responsible procurement throughout our supply chain. This Black Opal originates from Australian opal fields where we maintain direct partnerships with miners and local operators who follow recognized industry best practices, including transparent chain of custody documentation and commitments to fair labor. We prioritize material that can be traced back to its locality and that is free of undisclosed treatments, which is why this stone’s untreated status is important for collectors who value natural, responsibly sourced gemstones. Environmental stewardship is part of our sourcing criteria, and we work with suppliers who take measures to rehabilitate mined land and to reduce environmental impact where possible. For buyers building a conscious collection, an untreated Australian black opal with documented provenance aligns with ethical priorities and long term stewardship values, offering both aesthetic and moral satisfaction.

This specimen is well suited for a collector seeking an opal that combines visual drama with responsible origin and sound gemological attributes. Its size and tablet profile make it ideal for bezel or low cabochon settings that protect the stone from impact and minimize exposure to rapid temperature changes, preserving both color and structural integrity. Because opal has a unique hydrated silica structure, we recommend settings and wearing practices that reduce exposure to harsh chemicals and extreme heat, and we offer guidance on secure mounting to reduce the risk of damage. When purchased from The Natural Gemstone Company, this Black Opal comes with a detailed description of its weight, measurements, cut style, clarity assessment, polish grade, enhancement status, and origin, providing the documentation that discerning buyers expect. For collectors who prioritize natural beauty, verifiable provenance, and ethical sourcing, this multi color black opal represents a compelling addition to a conscientious gemstone collection.
