No shell rock around the heart front or back however are they able to outline the whole/full heart shape front and back with white (how they do the letters)? I'm not sure what a "blast line" is or what it looks like. I don't want any "rock pitch" on sides and top as I don't want the chiseled/rough look. I would like it to be smooth and polished (example like Justin's monument ). I hope that answers all the questions. Thank you for all your work on this issue it is greatly appreciated.
