Jade rough sliced into a slab for you to cut into beautiful cabochons. Note there are quartz Psudomorphs in this slice.   This is new old stock from the 1980's. Size of slab is about 115mmx 85mm x 5.5mm thick. Slight variation in the slab thickness from 5.5 to 5.9mm.   1st Photo show the slab wet.  2nd photo show the slab on a scale with 1cm =10mm per square.I believe this is USA rough. 

Happy to combine shipping and answer questions.  My inventory contains many other gemstones (Agate, obsidian, jasper, petrified wood, geodes)  PM any requests.
