A Bakerâs cyst is also known as a popliteal cyst or synovial cyst. It is a soft, fluid-filled lump that forms on the back of the knee. The lump is sometimes mistaken for a blood clot.
Geodes are typically agates. Agates are very common stones, and usually do not fetch a high price, but they are gorgeous to look at. Geodes in particular can be quite incredible, because they are like little miniature caves. On the outside, they look like plain, rough stones.
Like a cave, the mineral rich solution that leaves crystals behind inside a geode is a naturally occurring process between groundwater and the surrounding rock. Crystal size, color and chemical composition will vary and each individual geode is unique.Clear quartz, smoky quartz, amethyst, calcite, celestite, and chalcedony are examples of some minerals you may find inside a geode. Geodes from the same location often have the same type of mineral crystals.Some geodes are filled in with beautiful layers of mineral crystals.lear quartz, smoky quartz, amethyst, calcite, celestite, and chalcedony are examples of some minerals you may find inside a geode.
