I have seen jewel on jewel used before but its rare (does not fit in with common movement designs). The jewels are beveled to a round shape to reduce contact and lubricated with a very small amount of specially made oil. The jewels (mostly rubies or quartz) greatly increase the life of the internal parts of the watch.
