Green Opal (Madagascar)

Green Opal from Madagascar is admired for its soft to vivid green tones, often showing subtle cloud-like patterns or gentle color variations. Its smooth texture and fresh, natural appearance make it visually calming and elegant.

Because of its attractive color and workable hardness, Green Opal is commonly used for polished stones, cabochons, beads, and decorative objects. Each piece displays natural variations formed during slow mineral deposition.

✨ Fact & Fun Fact:
Green Opal is a hydrated form of silicon dioxide (SiO₂·nH₂O). Unlike precious opal, it usually does not show play-of-color. Madagascar is one of the world’s important sources of common opal, producing material in green, pink, blue, and white varieties. Opal contains water in its structure, which is why it is more sensitive to extreme heat and dryness than quartz.
