4.83 Ct. Boulder Opal from Australia

One beautiful opaque 4.83 carat pear shape multi color opal is presented with precise dimensions of 18.90 x 8.40 x 3.50 mm, cut in a tablet shape that highlights its vivid play of color, intense color intensity, and an excellent polish. This specimen is a Boulder Opal, mined in Australia, and it arrives to you with absolutely no enhancement, a natural, untreated gem that displays a lively mosaic of hues across a dark ironstone matrix. The elongated pear silhouette offers graceful lines for contemporary or classic designs, and the tablet cut produces a broad, even face that allows the multiphase colors to read clearly from multiple angles. As a selection offered by The Natural Gemstone Company, this opal has been evaluated to ensure authenticity, natural origin, and the absence of any treatments, making it a dependable and unique choice for collectors and designers alike.

Visually the stone presents a rich, kaleidoscopic display with flashes of red, orange, green, blue, and violet dancing across a warm brown background, creating striking contrast and depth that is characteristic of high quality Boulder Opal. The ironstone body gives the gem added structural stability and an earthy backdrop that amplifies the play of color, while the tablet cut emphasizes the colorful patchwork and yields a comfortable surface profile for a protective bezel or a low profile setting. At 3.50 mm thickness the stone is substantial enough to be set into rings if protected by a bezel or halo, and it is particularly well suited to pendants, drop earrings, and statement brooches where the pear shape can be shown off vertically. For jewelry manufacture we recommend a bezel set design for daily wear, or a custom mount that cradles the stone and protects its edges, and we are happy to advise on metal choices, with yellow gold lending warmth to the orange and red flashes, and white metals accentuating blues and greens.

This Australian Boulder Opal is a conversation piece that carries both natural beauty and practical appeal, an excellent addition to a curated collection or a featured stone in a bespoke commission. Because it is untreated and originates from Australia, it is uncommon to find such an expressive multi color tablet cut in a neat pear form at this size, which enhances its desirability and potential for appreciation over time. Care for the piece is straightforward, avoid harsh chemicals, extreme temperature changes, steam and ultrasonic cleaners, and clean with mild soap, water, and a soft cloth to preserve the polish and vivid play of color.

This opal is ready to be transformed into an heirloom quality piece or added to a discerning collection, and we welcome the opportunity to help you realize its full potential.
