The first thing to set is the mining properties for your block. Add a comma after the last property, and add the following properties to your json file:
"blockmaterial": "Stone",
"resistance": 3.5
The blockmaterial property determines what tools are effective at digging this block. Setting this to Stone implies that it can be mined by pickaxes. For a complete list of block materials, view the EnumBlockMaterial section on GitHub.
