I have been searching the inter-net site for a vivid green cabochon and came across this eBay store http://stores.ebay.com/waly-beads_W0QQcolZ4QQdirZ1QQfsubZQ2d999QQftidZ2QQtZkm that has some very interesting Transvaal Jade that is knock your socks off green. Has a nice pattern to it also. I don't think it is an actual jade but I am going to place a bid on several pieces just to have on hand for inspiration.
