6.65 Ct. Boulder Opal from Australia

Allow me to introduce a singular treasure from The Natural Gemstone Company, a stone that speaks to collectors and connoisseurs who demand both rarity and heart. This is a Boulder Opal of exceptional presence, an opaque, freeform gem weighing 6.65 carats, with the precise dimensions of 24.54 by 7.92 by 3.36 mm. The cut is not applicable because this piece has been artfully fashioned to preserve the natural contours and striking color patches that make Boulder Opal so coveted. Originating in Australia, each facet of its existence affirms its authenticity and its story, from the rugged field where it formed, to the hands that shaped and polished it into a wearable canvas. Stones of this character are produced in truly limited numbers, and ownership confers membership in an intimate circle of enthusiasts who appreciate natural beauty without compromise.

Visually this Boulder Opal performs with intense color intensity and an excellent polish that allows the play of color to dance across the surface with lively movement. Hues of electric green, cobalt blue, fiery red, and warm amber appear in shifting patterns, sometimes streaking in linear bands and sometimes pooling into flashier patches, all set against the contrasting ironstone matrix that gives Boulder Opal its grounded, earthy appeal. The clarity has been evaluated at eye level as very slightly included, a grading that in this context enhances rather than detracts, because the minor inclusions serve as fingerprints of origin, confirming that this gem is natural and untreated. There has been no enhancement, no filling, no backing, nothing artificial applied to intensify its spectacle, which is a rare and highly desirable condition for opal collectors and bespoke jewelers alike.

Because this is a freeform gem, the possibilities for bespoke design are expansive and exciting, and we at The Natural Gemstone Company pride ourselves on pairing exceptional stones with thoughtful, enduring settings. The elongated shape and generous yet slender profile make it ideal for a custom pendant or a statement ring that celebrates the stone rather than constraining it to a uniform template. Its dimensions and weight offer a commanding presence on the finger or at the center of a necklace, while the natural ironstone backing of Boulder Opal provides a degree of structural stability that many collectors find reassuring for daily wear. For clients who prefer a more architectural approach, the freeform silhouette invites bezel work that both secures and highlights the opal, while those seeking a lighter, minimalist aesthetic will find that a custom bezel with a delicate prong reveal lets the colors breathe and interact with light.

This Boulder Opal is offered with the confidence and provenance that only The Natural Gemstone Company can provide, and it is presented as a limited opportunity for discerning buyers. Our inventory fluctuates with the seasons of mining and the fortunes of rare finds, and a gem of this nature and conservation status appears only sporadically. For the collector who seeks an unenhanced Australian Boulder Opal with intense color and an excellent polish, this piece represents a rare alignment of natural beauty, provenance, and craftsmanship potential. If you wish to reserve this stone, request detailed lighting view images, discuss custom mounting options, or arrange an in person viewing, our team is ready to guide you through every step with transparent documentation and tailored service. Owning this opal means owning a fragment of the Australian landscape as interpreted by the earth over millennia, and it is a privilege we at The Natural Gemstone Company would be honored to help you realize.
