About Us

Semya Corp, formerly known as Allstone, has always been a small, family run business and has always operated by the motto Quality over Quantity. We at Semya Corp don’t strive to be the largest producers of natural stone, however our goal is to produce stone products of the highest quality to consumers. We believe this guiding principle is reflected in our product line which includes landscaping stone, building stone, and thin stone veneer made from the highest quality Green Mountain Granite and is ideal for many different project types.
