1.17 Ct. Semi-Black Opal from Australia

I am pleased to present a beautiful natural Semi Black Opal from Australia, offered by The Natural Gemstone Company. This exceptional specimen is an opaque multi color opal, weighing 1.17 carat, and cut into a classic oval shape. The dimensions are 9.46 by 7.22 by 2.57 millimeters, and it has been fashioned in a tablet cut that highlights the stone surface and play of color. The stone displays medium intense color intensity, with a vivid mix of blues and greens that shift as the light moves, and it has an excellent polish that gives a satiny smooth finish to the top of the gem. There has been no enhancement to this opal, so what you see is the natural material as it was mined in Australia. The Semi Black Opal classification indicates a darker base tone than common white opal, which provides stronger contrast and a more dramatic display of color, while still retaining brightness and a lively palette. At The Natural Gemstone Company we pride ourselves on presenting honest, clear descriptions, and this opal exemplifies the kind of natural beauty and character our clients seek.

Visually this stone is striking for its directional play of color, with broad flashes of electric green and deep ocean blue that appear in ribbon like and cloud like patterns across the tablet surface. The tablet cut was chosen to preserve as much color and natural surface as possible, creating a low profile that is ideal for close set designs while allowing the color to breathe. The clarity grade is very slightly included, evaluated at eye level, which means the stone shows only minimal internal characteristics when viewed without magnification, and these features do not detract from its overall beauty. Because opals are formed of hydrated silica spheres, patterns and minor matrix features are part of what make each specimen unique, and the slight inclusions here add a sense of character rather than a fault. The medium intense color intensity places this opal in a wonderful middle ground, with enough chroma to command attention, while remaining versatile and wearable day to day. The excellent polish enhances the play of color by delivering a high quality surface that reflects light evenly, and the lack of enhancement assures collectors and designers that this gem is completely natural and untreated.

For design and wearing suggestions, this opal is perfect for a bespoke piece where the stone can be the star. Its oval tablet shape and shallow profile make it ideal for pendants and earrings where the stone sits comfortably and securely, or for a low bezel ring where the edge of the setting protects the gem from direct knocks. Because opal is softer than many other gems, a protective setting such as a bezel, halo or a low set prong design is recommended for rings intended for regular wear. Pairing this multi color Semi Black Opal with cool metals such as white gold or platinum will emphasize the blue tones, while warm metals like yellow gold or rose gold will bring out the green and subtle body tones in the stone, creating very different moods. A halo of small diamonds or bright white gemstones adds sparkle and contrast, lifting the opal visually and creating a luxurious balance between fire and play of color. For minimalist designs, a simple solitaire pendant will showcase the stone s natural motion and color shifts, while more elaborate settings can incorporate accent stones, engraved details, or mixed metals to reflect your individual style.
