2.80 Ct.Tw.Total Carat Weight Cabochon Opal Pair from Australia

This pair of natural boulder opals presents an elegant combination of depth and color, suitable for refined mounted jewelry. The stones are opaque, cushion shaped cabochons that exhibit a vivid multicolor play, predominantly blue and green tones with subtle shifts under transmitted light. Each stone has been precisely cut and polished to maximize the opal surface, resulting in an intense color intensity and an excellent polish that highlights internal patterning and color patches. The material is unenhanced, retaining its natural structure and appearance, and originates from Australia, a well established source for high quality boulder opal.

Technical specifications are as follows, the first stone weighs 1.30 carats, and measures 9.52 x 4.66 x 2.69 mm, the second stone weighs 1.50 carats, and measures 9.60 x 5.00 x 2.61 mm. Both stones are cushion in outline, and both are cabochon cut to emphasize the play of color typical of Boulder Opal. The cut and proportions have been controlled to provide stable settings in paired jewelry such as earrings, or matched accents in more complex designs. No treatments or enhancements have been applied to these stones, therefore color, body tone, and clarity are natural characteristics of the material as mined and polished.

The Natural Gemstone Company presents these pieces as matched components for fine jewelry fabrication, suitable for designers and collectors seeking natural boulder opal with consistent color and finish. Given their dimensions and weight, these stones are well suited for low profile settings that protect the opal surface while allowing the color to be viewed from multiple angles. Care recommendations include avoiding prolonged exposure to excessive heat or strong chemicals, and resetting or cleaning should be performed by professional jewelers familiar with opal care. Documentation can be provided upon request to confirm origin, weight, and the absence of enhancements, supporting confident selection for commissions or inventories.
