It’s a morbid topic but a necessary business. People do die and their loved ones buy tombstones. And Colma, California, where a significant portion of the deceased population of the Bay Area is laid to rest, is home also to long-time family stone-carving businesses. Bocci & Sons, founded 113 years ago, closed up shop four years ago only to be purchased recently by Russian immigrants who have taken up the chisels. While not related to the family, they are carrying on a name that has been in business for almost 1,000 years, starting when the Bocci family mined marble in the Italian alps.
