Luminous Versatility for Custom Fine Jewelry

Sourced primarily from South Australian sedimentary basins, these loose gemstones display exceptional purity without any backing material. Because they allow light to enter from multiple angles, they are highly favored by custom designers. Jewelers often utilize open backed prong or elevated claw settings to showcase their floating, three dimensional internal color play.

Alternatively, placing a crystal opal over a dark or black background in a closed bezel setting will dramatically enhance and intensify the color brilliance, mimicking the look of a high value black opal. Our loose crystal opals are hand cut to maximize their natural play of color, providing beautiful oval cabochons and unique freeform shapes for creative jewelry commissions.
