It is a double stone. And large. My father died in 2008. His side is engraved. Mom died eight months ago. I tried twice to get her side engraved. But the owner of company mother was very sick then died. I'm a little nervous about it being dropped and chipped or broken. And I can't take anymore stress or responsibility for fixing things. Just finally finished with moms estate. Except one big problem. Been dealing with husband's stroke and meds, etc. since August this year. Can't take anymore.
