Gem stone products exceeded our expectations.  I am retired, 70 years old and complete this project by myself. Following the instructions available from the wed site and looking at few UTube examples prepared me for a successful project.  Many positive complements from neighbors and three difference contractors. The products give a realistic appearance of real stone work.  easy to install, recommend you lay out you project before you start for best results. I am planning additional projects with this product.  best of all the Gem Stone staff were available to address my questions and offer suggestions.   below are before and after pictures of my first project with Gem Stone.
