Recently we found an interesting quartz formation very much like a japan law twin where a crystal termination sits at a right angle to another:-
Not having seen one for sometime it was quite a find!
Another favourite which could easily be justified as a take home purchase would be this gorgeous natural blue and purple sapphire chunk from Sri Lanka
Have you worked with one of these milky translucent quartz points, very interesting from the Himalayan regions.
Now let me go and make some room on my collection shelf!
