Gems

In cemetery have to go back through the other doors to pick up different gems, got the topaz but it isn't triggering the other gems to appear in the other door areas. Any help would be appreciated.

You can collect them at any time. Are you sure they aren't already in your inventory?

Just to be sure you're going to the right places, the gems are:
- in the secret cavern (where you used the planks to repair the bridge)
- in the cupboard in grandma's kitchen
- hanging from a tree in Hallow Hills (where the scarecrow is)
- in the butcher shop window in Scarecrow Alley
