4 in Gravestones for Minecraft 1.20.1. Nothing is left out — the list is complete, and the last column is why an item has a page of its own.
| Name | Identifier | Kind | Has a page because | |
|---|---|---|---|---|
| Chipped Gravestone | gravestones:gravestone_chipped | block | recipe | |
| Damaged Gravestone | gravestones:gravestone_damaged | block | recipe | |
| Gravestone | gravestones:gravestone | block | recipe | |
| Gravestone | gravestones:gravestone_technical | block | listed here |
3 have a page of their own, 1 are listed here only. Belonging to a tag, or dropping itself when broken, is not on its own enough for an item to need a page.
