MAW SIT SIT

This is a natural untreated slab of jade from Burma. I bought the rough from the gem market in Mogok -Burma. We have taken the photos with the stones wet and included both sides. We have cut some of this material and there are some fracture lines which you can leave natural or treat-we have natural untreated stone from this parcel in our sister store sedagems.

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  as the principle coloring agent, and kosmochlor forming the black spots.I bought this as a large rock in the market in Mogok on my last trip there and slabed it up.

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."
