A lapidary is an artist or artisan who forms stone, mineral, and gemstones into decorative items. Lapidary is one of the most fun and educational hobbies anyone can enjoy. You can introduce yourself and your children to a wonderful new hobby and maybe a home based business. Getting started with rock polishing helps to get on the road to a lifelong interest in nature and the world around us. Rock polishing is not only a learning experience — it also leads to a beautiful finished product that you will be proud to show off.
