Natural quartz geodes or nodules found in the Sahara desert, Morocco. These geodes are all lined with sparkling white minute quartz crystals which if set against a dark backdrop, shine brightly. Geodes form as bubbles of gas within magma (the term for lava when the molten rock is still underground). Because of the temperatures difference bwteen the magma and the pocket of gas, the crystals form slower, crystals which form slower tend to form in larger sizes and so with a geode, you have an outside which is made up of very fined grained crystals, too small to see and the inside, which is full of larger crystals. These geodes are slowly becoming harder to obtain as the collectors struggle to get to the site which is littered with old exposive mines from a previous war and when the geodes were stock-piled puff adders set – up home amongst them. These specimens are available in various sizes as geode fragments and come supplied in a card tray with information label.
