Siberian River Jade, SJW16 We polished a window in this Siberian River Jade specimen because it has a unique shade of blue/green that needed to be released. A jade flashlight reveals the high translucence in this stone. River jades from Siberian come in a wide spectrum of colors, most of which are highly translucent. The brown oxidation polishes to beautiful shades of browns to reds (for examples look at our Siberian jade river carvings). These jades have become very rare over the last eight years. The weight is approximately: 5 pounds The dimensions* are approximately: 7″x4″x2-1/2″ * Note that the dimensions are the longest dimensions for each measured dimension of the stone.
