1.66 Ct. Multi Color Cabochon Black Opal from Australia

One beautiful translucent 1.66 carat oval shape multi color opal with dimensions of 10.23 x 8.15 x 3.04 mm, cabochon cut, medium color intensity, and an excellent polish, no enhancement, origin Australia, Black Opal. As a Black Opal from Australia this gem already begins ahead of many market alternatives, because Australian black opals typically show stronger, more stable play of color and lower porosity than hydrophane Ethiopian opals, and this stone is untreated, which means its natural beauty will age consistently without the risk of fading or unexpected changes. Compared to common white opals and lab grown simulants, this translucent multi color Black Opal offers deeper color contrast and a naturally dark body tone that enhances red and blue flashes, making the fire more visible in everyday light. The cabochon oval shape and excellent polish reduce the likelihood of surface snags and micro abrasions, and the compact dimensions 10.23 x 8.15 x 3.04 mm with a comfortable 1.66 carat weight provide a substantial presence without excessive exposure that can increase risk of impact damage.

When considering daily wear durability, it is important to compare realistic performance. Opal is softer than corundum and diamond, but this Australian Black Opal is among the more resilient opals on the market due to its origin, density, and lack of enhancements. The medium color intensity means the stone does not rely on extreme thinness to display its color, so it can be set slightly deeper without losing visual impact, which is a practical advantage for rings and bracelets. For the most wear resistant applications choose protective settings such as bezel or halo styles, which are easily paired with the oval cabochon form to shield edges while showcasing the multi color play. In contrast to many Ethiopian opals that can be hydrophane and react to humidity, this natural Australian specimen has a stable structure that tolerates daily temperature and humidity fluctuations better. With routine gentle cleaning, avoidance of harsh knocks, and sensible protective setting choices, this Black Opal makes an excellent candidate for everyday jewelry that outperforms many alternatives in value, authenticity, and visual impact. The Natural Gemstone Company stands behind the provenance and untreated status of this gem, and we recommend it for customers seeking a unique, durable, and high value opal for daily wear.
