Diabase has been selected as Rock of the Year for 2017. What sets this rock apart is its versatility. It is just as much in demand for sculpting and ashlar production as for producing high-grade ballast and chippings as well as aggregate for producing building materials. Ground diabase contributes as primary rock flour to soil improvement.
