Opal – Natural mineral.
Opal is a precious, amorphous, hydrated silicate mineral (SiO₂·nH₂O), composed of silicon dioxide with varying amounts of water (up to 20%). Unlike quartz, it has no crystalline structure; instead, it consists of microscopic silica spheres that diffract light, creating the phenomenon of opalescence — the famous play of color that makes opal appear to “dance” with light.
Main varieties
Precious Opal: the valuable variety displaying iridescence across the full spectrum of colors.
Common Opal: the non-precious variety, lacking a strong play of color, often found in shades of white, pink, blue, or green.
Fire Opal: a transparent or translucent variety with a vivid orange-red hue, rich in energy and vitality.
