Hi,
I hope someone can answer this question. We're having a flagstone patio put in our backyard and the stone they are using is called "Milford Green" from Pennsylvania. (It also comes in Blue and Violet). Is this PA Bluestone? Any how, the guys did a great job on the patio but unfortunately they ran out of stone and there was still about 75 sqft to go. They bought a new palate of stone and shaped and cut it. When I got home from work I was mortified. The new stone was a very light tan/beige color. The rest of the patio is a nice dark green/greyish color. My first reaction was to have them pull it out. They told me that they can "buff" it down and it will be green underneath (with some circular sanding type machine). Huh? Won't the stone look all scratched up? Will it really be green underneath? What to do??? Sad

Hi Pam,
Wwell maybe the guys could be right. But the best way to tellthe true color in the stone is to look at the sawn edge. When the stone is quarried it can have a lot of coating on in of 450,000,000 years of mineral deposits on it. The freshly sawn edge willl reveal the sand color in teh stoneIf it looks green it will be green it should be a little darker with the powder from thr fresh cut worn of f. Instead of grinding try an acid wash, this should clean off everything but the bluestone or in your case green bluestone. grinding will do it but it will take a while for the scratches to wear down. but hey will after time. Grinding will remove the natural cleft.
