Underground. :) JK Just dig down until you hit bedrock. Jump up 5-12 blocks. Most diamonds are located 5-12 blocks above bedrock. Although it is possible to find them anywhere under 15. The gold should be located in this area as well. Hope I helped! :)
Apart from water and air, stone is the most common block, below the topmost dirt layer. Just dig, you'll hit some.
