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.
Geodes (Greek Î³ÎµÏÎ´Î·Ï - ge-ÅdÄs, earthlike) are commonly independent spherical masses of resistant mineral matter that are usually hollow. The extreme filling of a geode so that it is solid is also common.Some people refer to completely in-filled geodes as nodules, but the two names are not always consistently used.eodes differ from nodules in that a nodule is a solid mass of mineral matter, but some nodules may have a tiny void space in their interiors and the distinction between a geode and a nodule may be barely discernible if the cavity is miniscule.
