hand knotted, yes4. is it silk on silk or ?? -->
Maybe some silk in it, this quality is called 260l commmericial, 80% cotton, 20% silk. 5. is this prayer rug style -->
Due to the dome in the upper part it is a prayer, but the design with the garden also indicates "Garden of paradise".
6. what does "5 J G" indicate -->
Nothing important, maybe a bale or packing number.7. what is it worth -->
these rugs sell at a retail of ca. 55 - 60 $ per squarefoot. The fringes are a bit more golden toned than the rest of the warp. They also seem to be added after the rug was finished. This indicates that they added real silk fringes for the burn test, but the rest is no real silk.
You did not mention the size - is is about 5 x 3?
