11.56 Ct. Black Opal from Australia

This is a rare opportunity to own a singular piece of nature’s artistry, offered exclusively by The Natural Gemstone Company, one of the most trusted sources for exceptional gemstones. This is not a mass-produced item, and we present it to a select clientele who understand the appeal of owning a stone that is both extraordinary and inherently scarce. The gem is a Black Opal of remarkable character, displaying a deep, intense blue presence that reads almost like a nocturne captured in mineral form. Originating from Australia, the birthplace of the finest opals in the world, this stone carries both geographic pedigree and aesthetic distinction, making it a highly desirable asset for collectors, connoisseurs, and bespoke jewelers who prize individuality and provenance.

The technical attributes of this Black Opal underline its rarity and value. It weighs 11.56 carats and is fashioned into an elegant oval shape with dimensions of 21.29 by 14.93 by 5.38 millimeters, a substantial size that is increasingly uncommon in fine opals without compromise to color. The cutter chose a tablet cut to present an expansive, polished face that reveals the stone’s internal depth and color saturation, while maintaining a low profile ideal for refined settings. At eye level the clarity is graded as very slightly included, a testament to the gem’s natural origin and integrity, and these minor inclusions in no way detract from its overall optical appeal. Color intensity is described as intense, and the polish is excellent, delivering a high gloss that amplifies the stone’s luminous blue and violet flashes. Importantly, this opal is unenhanced, a completely natural, untreated specimen, and its Australian origin adds an additional layer of authenticity and cachet among discerning buyers.

Beyond the specifications, consider how this Black Opal performs when set into jewelry or presented as a showroom specimen. Its deep blue palette and subtle translucency allow for dramatic interplay with both warm and cool metals. In a finely crafted bespoke ring or pendant, the tablet oval face will read like a singular canvas, ideal for minimalist contemporary settings that emphasize the stone’s natural spectacle, or for intricate vintage-inspired designs where the opal becomes the central narrative piece. Because opals are cherished for their individuality rather than uniformity, owning this gem places you in an exclusive group who appreciate and acquire singular natural treasures. For collectors seeking pieces that stand apart, an untreated Australian Black Opal of this size and intensity is an uncommon acquisition and one that frequently gains attention at private viewings and auctions. We at The Natural Gemstone Company can assist in pairing this stone with a custom design that preserves its broad, reflective surface while ensuring secure and elegant mounting.

To ensure long term enjoyment and preservation of the gem’s striking appearance, basic care and handling guidance is recommended. Avoid exposure to strong heat sources and sudden temperature changes, and protect the surface from abrasive contact and harsh chemicals. Because this Black Opal is a natural, untreated specimen, store it separately from harder gemstones to maintain its excellent polish, and periodic professional cleaning will keep its surface lustrous. For further assurance, The Natural Gemstone Company can provide detailed documentation of the stone’s attributes and facilitate in-person or virtual viewings for qualified buyers. If you would like bespoke mounting options, private consultation, or secure shipping and insurance handling, our team is ready to create an elevated, confidential buying experience. Owning this Black Opal is more than a purchase, it is an invitation to join a private circle of collectors who value rarity, provenance, and the exceptional beauty that only a gem of this caliber can provide.
