Are diamonds more likely to be found around volcanoes?

I feel that diamonds are not likely to be found around volcanoes because diamonds are a form of compressed carbon and the area around volcanoes consist of basalt rock.

According to the website listed below Diamonds must be in areas of recent or past volcanic activity. This is because they are formed hundreds of miles below the earth in molten rock. Apparently one of the largest discoveries of diamonds is in teh middle of a stretch of river in teh country of Namibia. They are here because when they surfaced long ago as the result of a volcano they were carried by this river downstream, where the heavy diamonds dropped to the bottom along the way.
