Amethyst (Quartz) Beryl The products that are primarily mined in Maine are sand, gravel and crushed stone. Granite and slate are also mined in Maine just not as frequently. Precious gems, such as rubies, diamonds and emeralds are not found in Maine, but few semi-precious rocks may be mined in Maine, such as quartz, beryl and tourmaline. The State Mineral of Maine is Tourmaline, which is also the most valuable gem found in Maine. Rose Quartz Mining and Quarrying has been in Maine since the early 1800s. During the late 1800s, the granite industry was very competitive because that is what most of the buildings were made of in that time. Another aggressive industry from 1880 to 1904 was the slate industry for the same reason granite was popular. Slate's main purpose was to make roofing, but there were other purposes too. State Laws on Mining and
Quarrying In Maine there are several State Laws dealing with mining and quarrying. One example of a law dealing with mining and quarrying is that there are restrictions dealing with activities that would impact areas including wetlands, beaches, dunes and water bodies. This law also effects notable wildlife habitats or other vulnerable wildlife/environment locations. For more information on mining and quarrying laws please visit:
