3.13 Ct. Semi-Black Opal from Australia

This elegant Semi-Black Opal is a 3.13 carat oval, measuring 12.52 by 9.86 by 4.27 millimeters, expertly fashioned in a tablet cut to maximize its vivid play of color. Sourced from Australia and heat treated to enhance stability and visual appeal, this stone displays an intense color intensity with lively flashes of green, blue, and subtle violet that shift with every angle. The clarity is graded very slightly included at eye level, which is typical for natural opals and does not detract from the gem's overall brilliance. The polish is excellent, giving the surface a smooth, reflective finish that highlights the stone’s fire and depth, and the tablet cut provides a broad, luminous face that emphasizes the opal’s internal patterning.

As a representative of The Natural Gemstone Company I can confidently recommend this Semi-Black Opal for both bespoke and classic jewelry designs, from a striking solitaire ring to a refined pendant or a unique pair of earrings. Its weight and dimensions make it versatile enough to sit prominently in a ring setting or rest elegantly in a bezel for everyday wear, while the intense colors will draw attention without overwhelming complementary metals and settings. Opals are relatively soft compared to other gems, so I advise protective settings and occasional professional cleaning to maintain its luster, and avoiding prolonged exposure to harsh chemicals or extreme temperature changes. If you would like custom setting ideas, appraisal documentation, or close up images to assess patterning and color play further, I am happy to assist. The Natural Gemstone Company stands behind the authenticity and quality of every gem we offer, and we are available to answer any questions about origin, enhancement, and care, or to help arrange secure shipping and insurance for this beautiful Semi-Black Opal.
