As you explore the islands you will find many colored stones scattered across the land, sometimes hidden by trees or bushes.
To clear colored stones you will need to use Dragôn Shard Hammers. Clearing them will get you all kinds of useful resources including stones, tin ore, vine, copper ore, white clay, amethyst, larimar, malachite, and malachite ore.
Note that while some resources have a 100% chance of appearing when you clear colored stones, other, rare resources like amethyst and larimar have a 50% to 100% chance.
Our best advice is to clear as many colored stones as you can to maximize your chances of getting the best resources from them.
Remember that colored stones also regenerate after you clear them, but may take up to a day or even five days to reappear. See the article Do Resources Regenerate on Home Island? for more information.
