I have sold off many of my components to Fletcher Electronics VA3NRF in North Bay. I still have the large collection of CRYSTALS here and my prices on average $4 per rock with $2.20 postage shipping across Canada. The main list of crystals is at my www.nettyelectronics.com web site HOWEVER.. I have many crystals being sorted on sorting boards and written in my 3 ring binder SO… contact me and I can look up the rocks you need. I BUY crystals as well. 73 earl ve3ab
