About Maw-Sit-Sit - History and Introduction

Maw-sit-sit is a green gemstone that was named "maw-sit-sit" after the village where it was found in Northern Burma. Maw-sit-sit was discovered in 1963 by a Swiss gemologist called Dr Edward Gubelin. Since it is made of kosmochlor, chromian jadeite, chromian eckermannite, chromian albite, and other materials, maw-sit-sit is considered to be a rock, rather than a mineral. It is sometimes referred to as a variety of jadeite, but strictly speaking, maw-sit-sit is not jadeite, though it contains jadeite and is mined in the same area as imperial jadeite. Jadeite is a mineral, whereas maw-sit-sit is a rock. The dominant mineral of maw-sit-sit is kosmochlor and this sets it apart from jadeite, which is sodium aluminum silicate. Therefore, maw-sit-sit is best considered to be related to jadeite. The kosmochlor component of maw-sit-sit is what gives it a beautiful emerald-green color with blackish-green patches.

Maw-sit-sit is also sometimes referred to as "chloromelanite" or "jade albite", which are names given to rock composed of varying amounts of jadeite, albite feldspar and other minerals.
