3.36 Ct. Multi Color Cabochon Boulder Opal (Ironstone Opal) from Australia

This 3.36 carat oval, multi color Boulder Opal, ironstone opal, is a finely presented example of Australian opalism, sourced from established boulder opal fields in Queensland, Australia. It measures 12.54 by 8.72 by 4.17 mm and is a traditional cabochon, cut and polished to an excellent finish to maximize play of color. As an opaque specimen, the opal displays intense color intensity across a multi color palette, with a stable ironstone backing that enhances durability and depth of color. There is no enhancement, which is a critical factor for educated buyers who value untreated natural material, and the absence of infilling or dyeing preserves both market value and long term stability. From a grading perspective, this stone scores highly on color intensity and polish, with a strong, even body tone and a clean surface free of significant fractures or fillings. Clarity in opal grading focuses on the presence of cracks and potch, in this case the cabochon fashion and careful cutting have minimized visible potch interruptions, allowing the play of color to read across the face of the stone with minimal interruption. The ironstone matrix characteristic of boulder opal gives a practical advantage over thin seam opals, providing a natural backing that resists sudden stress, and the 4.17 mm thickness offers sufficient depth for secure bezel or prong settings.

For the informed buyer, the appeal of this piece is both aesthetic and technical, the rich, bold color functions as a symbol of personal power and distinction, and the measured attributes support confident acquisition by collectors and designers alike. At 3.36 carats and with an oval 12.54 by 8.72 mm footprint, the gem is well suited for a statement ring or a refined pendant, providing a wearable scale that retains presence without overwhelming a design. The Natural Gemstone Company stands behind the provenance and the stated grading characteristics, offering transparency about origin, treatment status, and cutting details to enhance trust and resale confidence. Considerations for care are standard for opal, avoiding harsh chemicals and extreme heat, and with proper setting this natural boulder opal will retain its brilliance, serving both as a distinctive personal emblem and as a durable, collectible gem for the discerning buyer.
