Maw
Sit Sit
(metamorphic
rock with a
complex composition)
Maw
Sit Sit was first identified by Swiss Gemologist Eduard
Gubelin in 1963 in a town by the same name in Burma. This
material is found where Imperial Jadeite is mined. Maw-sit-sit
is an aggregate of numerous minerals found in the famous
jade mining region of Tawmaw in the Himalayan foothills
of northwestern Burma. The six main components are:
Chromite, ureyite, chrome-jadeite, symplektite, chrome amphibole,
and a matrix of lighter minerals.
This material is opaque to translucent with flowing veins
of green and black. The matrix is dark green to black in
color. Veins that are emerald green to intense neon green
have occurred.
