Made of stone

Brief

**Open to photographers with a ranking outside the top 1000. There are two other 'Made of stone' contests currently open to other ranks. Take a look at the <a href="https://www.photocrowd.com/leaderboard/">leaderboard</a> for more information on Photocrowd rankings.** This most elemental of materials is one that driven and defined the evolution of our species. Until we learnt how to work bronze, which was as recently as 3000 BC, it was the use of stone tools that marked the Stone Age, lasting for over 3 million years. A stone is defined as a small piece of rock, and we still use them in many walks of life, including construction, ornamentation, and commemoration. This contest is interested only in stone as used by man, not in its un-excavated form in nature. And stone being used in its original state, not as an ingredient in products such as cement, concrete, or glass. Within those broad limitations any of its fascinating uses can be represented, both historical and current.
