One is given to players for free upon passing the gymnastics test in Artazon, but this cannot be repeated. These are the locations where players can find a Sun Stone in Pokemon Scarlet and Violet.
Where to find Sun Stones in Pokémon Scarlet and Violet
There are two places in Pokemon Scarlet and Violet where Sun Stones will appear, and one area has a guaranteed Sun Stone as a Pokéball item. In the Western Province by area oneSun Stones can spawn by the river with a forever stand next to a cliff and a tree. This can be accessed by looking towards the river and turning around to go through a small tunnel where the Sun Stone will be waiting. This is the only guaranteed location other than just passing the gymnastics test in shell for the Insect Gym. Neither of these two drops will respawn, but the river may have some shiny objects on the ground that have a chance of being Sun Stones.

The other area that players can find Sun Stones is the roast desert. The area is littered with random items like soft sand, Pokemon materials, balls, and potions, but any of the glowing blobs on the ground could be Sun Stones. They have a low spawn rate, but the desert spawns a lot of items at the same time, so it shouldn’t take long to find one.
