1.67 Ct. Black Opal from Australia

This listing from The Natural Gemstone Company presents a striking Black Opal, a multi color opal that captures the eye with deep, vibrant flashes and a luxurious, dark body tone. The stone is an opaque oval weighing 1.67 carat, with dimensions 10.20 x 8.12 x 3.18 mm, and it has been fashioned in a tablet cut that creates a broad, gently domed surface ideal for revealing play of color. The clarity grade is very slightly included, evaluated at eye level, and these minor natural inclusions do not detract from the gem s beauty. The color intensity is described as intense, and the polish is excellent, resulting in an even, glossy finish that enhances both the depth of the dark background and the brilliance of the color flashes. There has been no enhancement to this opal, and it is natural from Australia, a region renowned for producing premium Black Opal specimens.

Visually this Black Opal offers a dramatic and lively presentation, with concentrated patches of green and blue that shimmer across the tablet surface, and occasional hints of other spectral tones that become visible as the stone moves. The tablet cut gives the gem a flattened profile that is particularly suited to bespoke jewelry designs where a bold, low profile statement is desired. This shape and cut make the opal comfortable for everyday wear in styles such as bezel set rings, sleek pendant mounts, or elegant cufflinks, because the shallow dome sits close to the mounting while still providing enough surface to maximize the play of color. In soft indoor light the stone reveals a mysterious, brooding halo of dark tone that serves as a canvas for the lively flashes, and under brighter or more direct light the color patches become vivid and gemlike, attracting attention without overpowering a refined setting.

From a gemological and practical perspective this Australian Black Opal exemplifies the attributes collectors and designers seek in a high quality specimen. The intense color intensity is a hallmark of premium opals, and because the piece is unenhanced, you are acquiring a natural gem whose beauty is intrinsic rather than treated. The very slightly included clarity grade means that under normal viewing conditions the stone reads clean and vibrant, and those small internal features are part of the opal s natural character and origin story. The excellent polish not only contributes to visual appeal, it also ensures the stone will sit smoothly against metal and feel comfortable in wearable pieces. When planning a setting, consider metals and designs that provide contrast to the dark body tone, such as warm yellow gold to accentuate green and blue flashes, or cool white gold or platinum for a contemporary look that emphasizes the opal s luminous colors.

Care and handling are simple, and because this opal is solid and unenhanced, normal precautions for opal jewelry apply. Avoid sudden temperature changes, harsh chemicals, and high impact knocks, and clean gently with a soft cloth and mild soapy water when needed. For secure setting options, a bezel offers added protection along the perimeter, while a low profile prong or rubover mount can showcase the tablet top while keeping edges guarded. If you are considering personalization or bespoke work, our team at The Natural Gemstone Company can provide guidance on ideal dimensions and mounting styles to ensure the 10.20 x 8.12 x 3.18 mm oval sits perfectly in your chosen design. We pride ourselves on sourcing and presenting natural gemstones with transparency and care, and this Black Opal from Australia is a fine example of an unenhanced gem with exceptional visual impact.
