MAW SIT SIT This is a natural untreated large stone from Burma- Green colour. Drilled-east west Weight 258.25 cts app Size 70 x 36 x 12 app Maw-Sit-Sit Maw-sit-sit is a rare, intense green variety of jadeite found in Tawmaw, the jade mining region of North-Western Myanmar{Burma}. First discovered in 1963, maw-sit-sit is composed of jadeite and chromite with chromium (Cr) as the principle coloring agent, and kosmochlor (Ko) forming the black spots. There are two completely different minerals associated with the name “jade,” “nephrite,” and “jadeite.” Jadeite is a pyroxene, part of a rock-forming silicate mineral group associated with metamorphic rock, while nephrite is an amphibole, a variety of actinolite that is part of the rock-forming inosilicate mineral containing ions of iron and/or magnesium. The mineral Jadeite is comprised of blocky, interlocking granular crystals, while nephrite is comprised of fibrous crystals. These differences are what accounts for the identifiable characteristics of each mineral. Jadite is described as having a granular, or “sugary” texture, whereas nephrite’s texture is described as “silky.”
