The slabs available from The Gem Shop are all natural and not treated or polished.  Examples of polished slabs can be viewed on our Specimens Page.  The slabs have been cut in our lapidary and range in thickness from 4mm – 6mm.  Slabs are normally used for cabbing or to create other pieces of art.  If you do not see the type of slab you are looking for please email us at

Note: The pictures of the slabs are representative of our stock.
