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 may be drab on the surface, but these rocks are full of crystallized minerals on the inside. Geodes are irresistible. They fill display cases and museums everywhere. Iâve even got one on my desk at home: a smooth, brownish rock encasing milky lavender crystals. Itâs hard to deny the allure of a rock that is rugged and weathered on the outside, yet so sparkly and colorful on the inside.
