Maw-Sit-Sit: Green Rock, Composition, Origin & Care

Table of Contents

Origin and Formation

Maw-sit-sit is known from the Kachin State region of northern Myanmar. Its geological setting includes ultramafic rocks and complex alteration processes. Because it is an aggregate, composition can vary between specimens and deposits.

Appearance and Properties

The material is usually bright green with black, dark green, or white patches. Reported components can include kosmochlor, chromite, and other minerals; exact composition varies. Its toughness and polish depend on the proportions and arrangement of its components.

Identification and Collecting

Maw-sit-sit can be confused with jadeite, dyed material, and other green ornamental rocks. Reputable gemological testing and locality documentation are useful. Avoid assuming that green color or a jade-like appearance proves it is jade.

Care and Handling

Clean with a soft damp cloth and mild soap, then dry. Avoid harsh chemicals and ultrasonic cleaning when composition or treatments are uncertain. Protect polished pieces from impacts and store separately.
