New this week; Sage from USA, saltlamps from Pakistan and dreamcatchers from Indonesia. Very slowly, countries will open again, Morocco will open, and we expect a 40 foot container with Selenite, minerals and fossils next week.

More information

A geode or druse is a hollow or partially hollow, globular tuber that is covered with crystals on the inside. Usually geodes are between 2.5 and 30 centimeters, but this can vary greatly. They are found in sedimentary rocks and are sometimes very expensive. A geode consists of a thin but tight outer layer of silicates, usually filled with a layer of quartz crystals such as amethyst or smoky quartz, but there may also be rutile or calcite in it. There are also specimens of which the cavity contains water. They would have originated as "bubbles" in the liquid magma that rose in a crater pipe during an eruption. As bubbles collect in bubbles of milk under the membrane forming on the milk, gas bubbles remain stuck in the magma. These gas-filled cavities continue to exist after solidification of the magma and fill with saturated mineral solutions. A geode is created as a layer of silica in a guest room, usually a fossil cavity in the rock. The minerals in the water, which runs along the hardened outer shell, form crystals in the silical layer. Crystals slowly grow in the cavities. Agate is formed in the same way. If we weigh geodes and compare their weight, the lightest weight can sometimes contain beautiful crystals. Geodes are sawn through or broken with a special pair of pliers to make the inside visible.
