Ed,
If it sounds like fun, you might go hunting in the desert for "Saudi diamonds" (quartz) which can be cut into very nice diamond looking stones for not much money. Could be good souvenirs.
A buddy who was in Saudi Arabia working would go out in the desert at first light to see the stones glint or sparkle in the slanting sun light. Found a bunch of the stones. Had them cut/faceted in Bangkok for a few bucks. He had fun for years giving them away or selling them for $5-15 a stone to recoup the cost of cutting them. He had match boxes full of "Saudi diamonds" that looked like real diamonds.

Not sure, but I think the link is showing faceted "Saudi diamonds" and not CZ.
