24.85 Ct. Boulder Opal from Australia

I am pleased to present a remarkable natural Boulder Opal from Australia offered by The Natural Gemstone Company, a translucent freeform multi color opal weighing 24.85 carats, with dimensions of 28.30 x 17.20 x 4.92 mm. This piece displays vivid color intensity and an excellent polish, and it is completely untreated with no enhancement. The cut is not applicable as the gem is a freeform shape that celebrates the opal s natural contours, and the clarity grade is very slightly included evaluated at eye level. As a Boulder Opal, it retains a thin backing of its ironstone matrix, which gives the stone durability and a distinct, earthy contrast to the vibrant play of color. This specimen is a collector quality gem that will appeal to designers and connoisseurs looking for a bold and colorful focal stone.

Visually this opal delivers a spectacular blend of greens, blues, and flashes of warm red and orange that shift with movement and light, creating a lively and dynamic display. The translucency allows depth in the color play so that different angles reveal new layers and patterns, making each viewing unique. The surface has been finely polished to enhance brightness and to allow the colors to sing against the dark matrix edge. The freeform profile is ideal for one of a kind jewelry pieces where the cutter s artistic vision can be preserved, or for a custom mount that follows the stone s natural outline. Because of its vivid color and polished surface, this Boulder Opal works beautifully as a statement pendant, a sculptural ring centerpiece, or an artful brooch, and it can sit flush in a bezel or be highlighted with a minimal prong design that protects the thinner edge.

For practical considerations please note that the measurements 28.30 x 17.20 x 4.92 mm will guide your jeweler when planning settings and fittings, and the 24.85 carat weight means the gem has substantial presence without being overly bulky. The presence of very slight inclusions at eye level is typical of natural opals and does not detract from the overall beauty, rather it testifies to the stone s natural origin. When choosing metal pairings, warm metals such as yellow gold and rose gold will amplify the red and orange flashes, while white gold and platinum provide a modern contrast that emphasizes the blues and greens. As with all opals, avoid harsh chemicals, high heat, and ultrasonic cleaners, and clean with warm soapy water and a soft brush if needed. Store the opal separately from harder gems to prevent abrasion and consider a snug bezel setting for everyday wear to protect the thin profile of the freeform shape.
