Size 11.5mm Inner diameter 17cm Sagenitic refers to the general term for stones containing elongated crystals, and they are called "Sagenitic Quartz" or "Sagenitic Agate." It is sometimes simply called "Sagenite." Quartz is known to contain inclusions of many types of minerals. The most common inclusions are elongated crystals such as needle-like or fibrous types. The most well-known is rutile, but there are also tourmaline, actinolite, tremolite, and goethite. When the type of inclusion in the quartz can be determined, it is called "Rutilelatedquartz" or "Tourmalinatedquartz," with the name of the inclusion. However, it is usually not possible to determine the type, and it is collectively called sagenitic quartz. In Japan, these have been called "needle quartz" for a long time. Depending on the color and appearance, they are sometimes called by images such as "susuki quartz (containing brown tourmaline)," "grass quartz (containing green crystals such as actinolite)," and "dew quartz (with tiny mineral particles attached to the tips of needle-like crystals)."
