2.51 Ct. Boulder Opal from Australia

Presenting a beautiful opaque 2.51 carat freeform shape multi color opal from The Natural Gemstone Company, a striking Boulder Opal that captures attention with its rich play of color and natural character. This gem measures 14.90 x 8.11 x 3.22 mm and has been fashioned with a tablet cut to maximize the surface area of color. The color intensity is intense, and the polish is excellent, producing a bright, reflective finish that enhances the opal fire. This stone is natural with no enhancement, and it originates from Australia, where Boulder Opals are formed within ironstone host rock. As soon as you see the surface, you will notice the depth and movement of color that set this piece apart, and you will understand why collectors and designers prize Australian Boulder Opal for unique jewelry creations.

Visually this Boulder Opal is a study in blues and greens with flashes of aqua and teal that shift as the light or viewing angle changes. The tablet cut presents a broad, flat surface, which allows larger fields of play of color to show at once, creating a dramatic mosaic of iridescent patches that seem to glow from within. The freeform shape gives the gem an organic, artistic silhouette that reads as both contemporary and timeless. Included in the pattern are darker matrix areas that anchor the bright color, adding contrast and a natural aesthetic that is characteristic of Boulder Opal. The combination of intense color, contrasting host rock hues, and a high polish creates a gem that looks alive, appearing differently under varying lights and angles, making each viewing an engaging experience.

This 2.51 carat Boulder Opal is particularly well suited for a statement pendant or a bespoke ring where its freeform shape and tablet cut can be showcased. The dimensions of 14.90 x 8.11 x 3.22 mm provide a substantial presence without overwhelming a design, giving jewelers ample room to create a secure bezel or an elegant prong setting that highlights the colorful surface. Boulder Opals benefit from their natural ironstone backing, which often makes them more robust than other types of opals, yet care in setting remains important. For a pendant the piece can be set with an open back to let light play through the thinner edges, or with a solid backing to emphasize the surface color and protect the stone. For a ring we recommend a protective bezel and a design that prevents hard knocks to the table, while still allowing the gem to show its full color.

When you choose a natural, unenhanced Boulder Opal from The Natural Gemstone Company you are choosing a one of a kind gem that requires mindful care to preserve its beauty. Avoid exposure to household chemicals and prolonged periods of direct heat, and clean the opal gently with a soft cloth and mild soap and water, avoiding ultrasonic cleaners and steam. Store the stone separately from harder gemstones to prevent scratches, and consider professional inspection of the setting periodically to ensure the gem remains secure. Because this opal is untreated and originates from Australia, its natural color and matrix are authentic features that contribute to its value. At The Natural Gemstone Company we provide detailed images and measurements so you can evaluate the piece with confidence, and we offer assistance with custom settings and professional recommendations from our experienced gem specialists.
