The artists at BROKEN ROCK DESIGN create original hand carved sculpture for Homestone house numbers using original rock art and designs from petroglyphs scattered across the world.  Petrogyphs, from the Greek words petro for "rock" and glyph for "carving",  have been used for thousands of years to identify places and events. Petroglyphs are created when pecking or abrading it away from the base stone removes a patina that formed over many years.  This leaves base rock exposed that is a different color and texture from the patina. The artists create the Homestone patina by layering the base stone with a colored sealer.  This gives them control over the color of the patina and allows more dramatic variations than occur in nature and it is created in hours rather than thousands of years.  After the patina is removed for the numbers and your design, color can be added to the pecked areas to enhanced the contrast.  This creates piece of art that will be unique to your business or home.
