1.39 Ct. Multi Color Black Opal (Dark Opal) from Australia

This Black Opal, weighing 1.39 carats, is a striking example of natural Australian opal that balances rarity and wearable size. The gem is cut into a refined fancy shape and measures 10.43 by 6.43 by 3.14 mm, a profile that makes it ideal for a variety of jewelry applications from a signature ring to a pendant centerpiece. The tablet cutting style presents as a flattened table face that emphasizes the play of color across a broad plane, while the intense color intensity and excellent polish ensure that each flash of hue reads with clarity and vibrancy to the naked eye. This piece is opaque by nature, which is characteristic of high quality Black Opal, where a dark body tone serves to heighten the contrast and saturation of red, green, blue and orange spectral flashes. There has been no enhancement to this stone, so its optical properties and surface finish are entirely the product of skilled cutting and the inherent character of the opal material, and its Australian origin situates it among the most respected sources for premium Black Opal.

To an educated buyer, several technical attributes make this gemstone particularly desirable and defensible as an investment. Color grading for opal focuses on play of color type, color intensity, and body tone, and this specimen rates highly across all three measures. The multi color play is broad and well distributed rather than localized, which increases visual interest and resale appeal. The intense color intensity indicates saturated, strong flashes that read from multiple angles, and the dark body tone typical of Black Opal provides the contrast necessary for those colors to appear more vivid. Clarity in opal is a different language than in crystalline gemstones, and here clarity should be understood as freedom from fractures that impact structural stability and from potch patterns that obscure color. This tablet cut reduces the visibility of internal non color zones while maximizing surface area for color play, and the excellent polish minimizes light loss at the surface, improving both spectacle and apparent depth. All of these attributes, combined with the precise carat weight and compact dimensions, create a balanced, marketable gem that appeals to collectors who prioritize both aesthetic excellence and documented, natural provenance.

Ethical sourcing is central to how The Natural Gemstone Company presents this Black Opal, and we emphasize traceability, environmental stewardship, and social responsibility as core values. Australia has well established regulations for opal mining and many miners operate with community accountability, and we work directly with vetted suppliers to ensure that every purchase can be traced to responsible mining operations. The fact that this stone is untreated aligns with a conscious consumer mindset, because it avoids the additional chemical and thermal processes that can increase environmental impact. We prioritize partnerships with suppliers who follow best practices for land rehabilitation, fair labor conditions, and transparent transaction records, and we can provide documentation on request that supports provenance claims and ethical sourcing statements. For buyers who insist on conflict free and environmentally responsible gems, a naturally occurring Australian Black Opal with no enhancements fits cleanly into a collection built around sustainability and integrity.

For practical collection considerations and care, Black Opal requires respectful handling that preserves its beauty across decades. The gem should be set in protective settings that reduce the chance of impact to the tablet face, and we recommend pairing this stone with recycled precious metals whenever sustainability is a priority. Cleaning should be limited to mild soapy water and gentle cloth drying, with avoidance of ultrasonic cleaners and sudden temperature changes that can stress opal structure. Because opal can be sensitive to extreme dryness and rapid thermal shifts, storing it away from direct heat and in humidity stable conditions will maintain its stability. The Natural Gemstone Company stands ready to provide additional grading information, high resolution imagery, and supply chain documentation to support your purchase decision, and we can assist with custom setting recommendations that honor both the gem geometry and the ethical values that matter to conscious collectors.
