Stone is polished by hours of work by a skilled craftsman. There is no "coating" that is applied. The beautiful, nearly permanent shine on memorials is created by a series of diamond impregnated pads, water, and a skilled craftsman. If the polishing process is done incorrectly, the stone can overheat causing the stone surface to prematurely crumble.
If you were given only a few square feet on which to tell your whole life story, what would you say? What events, and memories would you include? What would you want your great, great grandchildren to know about you? Pre-need memorials give you the chance to make important decisions about the story of your life.
Who's your hero? Memorialization is about recording the stories of the every-day heroes that impact our lives more than any other people on earth.
