Maw sit sit is a vivid green, jade-like rock composed of a mixture of minerals, including kosmochlor, jadeite, albite, chromian amphiboles and others. It is named after the village of Maw Sit Sit in northern Myanmar, near classic jadeite deposits. With hardness typically in the 6–7 range and good toughness when compact, it is used similarly to jade in cabochons, beads and carvings.
Price History
Value Drivers
Carat weight is important for larger cabochons and carvings that display broad areas of intense green color with attractive mottling or veining. Small pieces are common, but large, fine-quality pieces with consistent, saturated color are much rarer and command higher prices.
Color is the primary value driver. The best maw sit sit shows a bright, saturated chrome-green background with minimal muddy or dark patches, often accented by black or dark green streaks. Dull, grayish or overly blotchy material is less valuable, while stones that approach jadeite-like color intensity are more desirable.
As an aggregate rock, 'clarity' relates to density and absence of cracks, vugs and crumbly zones. Compact material with a smooth, even texture and coherent patterning is preferred. Excessive fracturing or unstable areas reduce durability and appeal.
Maw sit sit is cut into cabochons, beads and carvings. Good cutting highlights the most attractive color and pattern while avoiding weak or heavily included areas. A high polish is important to bring out saturation and depth. Shapes often echo those used for jade, including bangles and domed cabochons.
Market Dynamics
Known primarily from northern Myanmar, maw sit sit occurs in the same general region as jadeite jade but in more limited, localized deposits. Production has been sporadic and constrained by access, political conditions and mining intensity.
Demand is niche and driven by jade enthusiasts, collectors and designers seeking distinctive green, jade-like material with its own identity. It is especially popular in Asian markets and among collectors familiar with Burmese jade fields.
Recent Trends: niche but stable collector interest, with fine, well-documented stones achieving strong prices through specialist dealers and auctions.

Insights
Maw sit sit was formally described as a distinct rock type in the 1960s and 1970s after gemological study of material from Myanmar.
Because of its jade-like appearance and geographic association, maw sit sit is sometimes misrepresented or confused with jadeite; proper gemological testing is required for differentiation.
The vivid green color is tied to chromium-bearing minerals such as kosmochlor within the rock.
Maw sit sit is generally not subjected to the same bleaching and polymer impregnation treatments commonly seen in lower-grade jadeite, but enhancements cannot be ruled out without testing.
Fine maw sit sit with bright, homogeneous green is considerably rarer than mottled, darker, or brownish varieties.
Because it is cut and marketed in similar forms to jade, maw sit sit often occupies a parallel niche in jewelry designs emphasizing bold green cabochons and carvings.
