2.80 Ct.Tw.Total Carat Weight Multi Color Cabochon Boulder Opal (Ironstone Opal) Pair from Australia

This pair of natural boulder opal, Ironstone Opal, offered by The Natural Gemstone Company, consists of two opaque cabochon cut stones weighing 1.30 carats and 1.50 carats respectively, with a combined weight of 2.80 carats. Both stones are cushion shape, exhibiting multicolor play with an intense color intensity and an excellent polish that enhances surface luster and pattern clarity. The individual dimensions are 9.52 x 4.66 x 2.69 mm and 9.60 x 5.00 x 2.61 mm, measurements that reflect careful cutting to preserve broad color areas while maintaining consistent thickness for secure mounting. These are Australian origin boulder opals, each formed within its ironstone host, providing a natural and stable backing that retains the distinctive opal color against a dark matrix. No enhancements have been applied, and the material is presented as natural, intact boulder opal with typical ironstone contrast.

The characteristics of this pair make them especially suitable for matched settings where evenness of face color and complementary patterning are important, such as paired studs or a coordinated pendant and stud combination. The cabochon cut supports maximum color play when viewed from typical wearing angles, and the cushion outline offers a modern rectangular silhouette that adapts well to both minimalist and more structured mounting styles. As with all gemstones sourced and distributed by The Natural Gemstone Company, these stones are supplied with full disclosure of origin and treatment status, and they have been inspected to confirm polish quality and natural state. The ironstone matrix contributes to durability compared to freeform opal material, and the overall proportions deliver a balanced appearance with robust color presence suitable for jewelry design and collection.
