These quartz geodes appear as dusty mini boulders but inside is a cave of quartz crystals. They are formed from volcanic gas balls which cooled and formed hard outer coating. The inside is hollow with many crystals that formed when the minerals and gases cooled.
These geodes from Morocco have been cracked open and colour treated with a brilliant colour. The tiny, naturally terminated crystals within will add sparkle to home decor or a mineral collection. No two geodes are alike!Sizes vary.
