The natural aggregates in our Gemstone® units are brought forth by grinding the face of the unit to a smooth “burnished” finish; a light coat of sealer is then applied to help protect the block during delivery and installation and also to give it an added sheen and to assist in the resistance of natural elements that can affect the surface. Gemstone units are used in both internal and external building applications.

There are many standard sizes and shapes to select from and a variety of colors that show the natural beauty of the aggregate. Gemstone units conform to ASTM C90 standard specification for loadbearing concrete masonry units.
