11.55 Ct. Boulder Opal from Australia

One beautiful opaque 11.55 carat trillion shape multi color opal, presented with dimensions of 18.10 x 16.59 x 5.08 mm, offers an immediate impression of rare and restrained glamour. This is a Boulder Opal from Australia, offered without any enhancement, and fashioned with a tablet cut that lays the lively spectrum of color across a broad, luminous plane. The stone carries a clarity grade of very slightly included, evaluated at eye level, and the surface has been given an excellent polish, so the play of color reads with intense color intensity and a clarity of expression that few stones can match. The trillions contours are thoughtfully preserved in a shape that speaks of modern refinement and classical balance, making this opal eloquent both as an objet and as the central element of a bespoke piece.

Viewed closely, the stone reveals a landscape of shifting green, blue, and flashes of etheric violet, each hue riding on a backdrop of natural ironstone that anchors the gem with earthy contrast. The tablet cut has been chosen to maximize the gem s surface spectacle, allowing the color to float and recompose with each turn, an effect that rewards a wearer and a collector in equal measure. As a Boulder Opal the gem retains a portion of its native stone matrix, a quality that gives it character, durability, and an unmistakable sense of origin, a signature of authenticity and provenance. At 11.55 carats this opal occupies a rare weight class for a stone of such integrity, and the specific dimensions make it an ideal candidate for a striking ring, an artful pendant, or a singular brooch, pieces that will broadcast the owners refined taste and confidence.

The Australian origin and the absence of enhancements underscore the gem s natural pedigree and long term desirability, attributes that collectors and connoisseurs understand instinctively. For settings that best honor the stone s colors and protect its tablet surface, we recommend a custom bezel with a gently elevated profile, or a secure prong setting paired with a protective gallery, metals selected to complement the vivid palette might include warm 18 karat yellow gold to heighten green and blue fluorescence, or cool platinum to emphasize cooler blues and violet notes. Care is simple and straightforward, occasional gentle cleaning with warm water and mild detergent, avoidance of harsh chemicals and sustained heat, together with secure storage when not worn will preserve the opal s brilliance for generations.
