Beautiful quality cracked quartz geode clusters from Morocco. A geode is a hollow, more or less spherical stone/nodule that is lined with crystals on the inside, in this case, rock crystal. These are loose clusters, not a complete geode! (see photo!). Clusters are between 3 and 6cm each. These Moroccan geodes are often very thin-walled and sparkle beautifully in the light due to the lovely rock crystal. A very nice addition to your living room or other space in the house.
