I would submerge pieces of concrete in water for several hours. Then put them in freezer. After freezing, thaw them again. Repeat and repeat the process until concrete fully degraded. Does it worth the effort?

This is by far the most odd question I have seen on Yahoo Answers so far.

I would recommend talking to a jewler and find out what can eat away at/disrupt the concrete that will not affect the gold or gems.

Just curious...where did you find this treasure laden slab?

I would suggest vinegar and a stiff brush to dissolve the concrete. Anything that dissolves in that isn't a real gem. 

Good luck 

If you feel like sending me a gem feel free - or else 10 points would suffice - good luck...

its kind of hard to answer that without seeing it but i think you should chisel lightly or try soaking the concrete in water to soften it up and then scrape around the items...

Hydrochloric acid, full strenth. Available at your local chemical supply store. Keep plenty of baking soda on hand, and use it carefully and sparingly, this is NASTY stuff.
