limestone tiles

Answer 1

Jerusalem Stone, a durable limestone developed over millions of years of ocean water, sand, and shells coming together to create a durable stone. Each variety reflects its own unique hue: bone, gold, grey and rose. Much of the stone contains million year old fossils which add to its depth of beauty. The family purchased quarries in Israel.

Answer 2

Limestone is made up of the mineral calcite (CaCO3) almost exclusively.  It is, by nature, soft (#3 on the standard hardness scale of 1-10 used by geologists.  It is also slightly soluble in water.  

So it just isn't something that I would consider durable.  Of course that depends on the application.
