1.17 Ct. Cabochon Semi-Black Opal from Australia

If you are searching for a singular gemstone that answers the need for rarity, depth of color, and a feel of the extraordinary, this semi black opal from The Natural Gemstone Company is the perfect solution. This one point one seven carat oval multi color opal measures nine point four six by seven point two two by two point five seven millimeters, with an elegant cabochon cut that showcases its play of color across the dome. The opal is graded very slightly included when evaluated at eye level, and it carries a medium intense color intensity with an excellent polish. There has been no enhancement to this stone, and its origin is Australia, a region world renowned for producing opals with exceptional character. For someone considering an engagement piece, a custom heirloom, or a collector seeking an unusual specimen, this semi black opal provides a statement of individuality while meeting the technical expectations of discerning gem buyers.

What truly sets this semi black opal apart is the way it delivers brilliance through play of color rather than through the refractive sparkle more commonly associated with faceted gems. Where a diamond dazzles with white light dispersion, giving a brilliant and scintillating sparkle, and where sapphires and emeralds offer deep saturated body color, this opal offers shifting flashes of green and blue that move like a living light within the stone. Those flashes appear against a darker potch base that subtly enhances the contrast, making each color pop with greater clarity and life. The result is brilliance of a different kind. Instead of relying on facets to break light apart, this opal scatters light from within, producing bands and patches of color that change with every shift of angle and every alteration of lighting. Compared to more common gemstones, it stands out because its beauty is variable and personal, rewarding the owner with a private and evolving visual experience that cannot be fully captured in a single photograph.

From a practical perspective, this semi black opal is an ideal choice when you want a gemstone that communicates refinement and uniqueness without requiring constant compromise. The cabochon cut maximizes the visible color play while preserving good durability for everyday wear when set thoughtfully, and the size and shape of nine point four six by seven point two two by two point five seven millimeters make it perfectly suitable for rings, pendants, and bespoke pieces that highlight the stone as the focal point. The clarity grade of very slightly included at eye level means that the gem presents a clean face to the viewer while still retaining the characteristic inclusions that often authenticate natural opals and add to their charm. There is no enhancement, so what you are seeing is the natural interplay of minerals and silica that formed this opal over ages in Australian conditions. For lovers of gems who prioritize authenticity and the story behind their stones, this piece fulfills both aesthetic and ethical expectations.

When comparing brilliance and desirability side by side with more familiar options, consider the different emotional responses each gem can elicit. Diamonds offer timeless brilliance and universal recognition, sapphires offer regal color depth, and emeralds offer classic verdant beauty. This semi black opal offers something more intimate and unexpected, a living colorscape that can evoke oceans, auroras, and painterly skies all at once. Collectors and romantics alike will appreciate how the medium intense color intensity provides a balance between vividness and subtlety, allowing the stone to play gracefully under natural daylight and warm interior light. If your quest is for an engagement ring that will be remembered for its singularity, or for a collector piece that enriches a cabinet with genuine Australian provenance, then your search ends here with The Natural Gemstone Company offering a one point one seven carat, oval, multi color, semi black opal that is cabochon cut, very slightly included at eye level, medium intense in color, excellently polished, untreated, and sourced from Australia.
