Few natural inclusions contribute as much character to a gemstone as dendritic formations. In fine Peruvian Blue Opal, exceptional dendritic patterns are actively sought by collectors because no two stones are ever alike, making each example genuinely individual.
At 7.50 carats and measuring 17.93 x 13.02 x 7.23 mm, this oval Peruvian Blue Opal displays a rare Paraiba Blue Green color with translucent clarity and striking dendritic inclusions. The pattern creates a natural landscape within the gemstone, adding visual interest that extends well beyond color alone. Combined with the attractive blue-green body color, the result is a stone that rewards close inspection and continued appreciation.
Completely untreated and naturally formed, the gemstone preserves its original structure and distinctive internal features exactly as nature created them.
It feels special without being loud and wears well without being boring.
The dendritic inclusions, black to brownish-black branching patterns visible in many Peruvian blue opals, are composed of manganese oxide (MnO₂ in dendritic pyrolusite form). Learn more about Peruvian Blue Opal.
