Slate is an excellent material for creating a stunning and unique headstone. Smooth and thinner by design, it makes a stately and elegant memorial and is easily customized to honor the unique qualities of your loved one. Classic monolith memorials are often found in historical cemeteries and make for a striking monument in any cemetery setting. A monolith is a tall, single tablet of stone that is typically cemented into the ground so that the base is barely visible or completely hidden.
