Rainbow Moroccan Geode Keychain

Rainbow geodes have been treated to offer a variety of dyed hues which include blue, teal, pink and purple. The inside of these natural agate geode specimens from Morocco are covered with beautiful tiny, naturally terminated crystals and have a polished front.

These small geodes are composed of various forms of quartz. The inner core is commonly the crystalline variety, while the outer skin is made up of microcrystalline quartz or agate. They are formed from volcanic gas balls which cooled and formed hard outer coatings. The inside is mostly hollow with many crystals that formed when the minerals and gases cooled.
