The sun stone was first introduced in the Pokemon Gold and Silver games. This stone evolves Petili, Gloom, and Sunkern.
Just by winning the bug catching contest in the national park
You can evolve gloom to bellossom usig the sun stone.
Only one's I know of is Graveler, Magmar (With a Magmarizer), Machoke, Rhydon (With the protection item), Haunter, Dusclops (With Reaper Cloth). If you know anymore just edit this.
use it on sunkern
Sunkern evolves into Sunflora with the use of a Sun Stone.
a moon stone can change a Pokemon to a darker form at night and a sun stone can change a Pokemon to light during the day this only works with certain Pokemon like eevee though
There are two Pokemon that evolve with a sun stone. Gloom into Bellosom Sunkern into sunflora
Go underground
Gloom can evolve into Bellusme if you give it a Sun stone.
Gloom and Sunkern.

You can get a sun stone by digging underground using your Explorers Kit.

There is no Pokemon found solely in Diamond version that can be evolved with a Sun Stone. Gloom- can be found in Routes 224, 229, and 230. Sunkern- You need the Poke Radar to find this Pokemon in the Northern area of Route 204.
You can get a sun stone underground,but its VERY hard to dig one so good luck Hope this works out.
