Yes but they are extremely rare
fossils, shards, stones, plates, spheres
You can find all the evolution stones underground by digging. If you get lucky you may dig up some. I find the most common are the thunder stones. I have dug up moon stones, fire stones, water stones, and sun stones. There may be more. I've just remembered! I've also dug up leaf stones but no shiny stones.

The ovel stones are in the explore kit but when in the tunnel u dig the up or out of the wall

Actually,you can get endless leaf ,fire ,sun ,moon, and thunder stones when you dig them up underground.You go underground by going to Eterna city and going into the house next to the Pokemon center. When you are inside, talk to the elder and he will give you an explorer kit(a key item).Use the explorer kit and you will go underground. :)Hope you find lots of stones!(:

Help Carter in the Dig-Site and you might randomly dig up Moon Ore.
I'm not sure exactly if you can get it in diamond..... But if you can, you have to dig it up underground
You can find one with Cleffa or Clefairy (5% chance) or you can dig underground.
