Take a look at this stone. What do you see inside it? Probably you are observing a seabed, or maybe it is just someone’s aquarium? Actually, this is nothing but an Opal – a commonly known gemstone, more accurately so-called Oregon Opal, obtained from Opal Butte, located in Oregon. But how the Opal could contain a “piece of the ocean” inside it? It looks like the nature itself has taken an effort to create this unusual gem at the beginning of time.
