One Word Prompt #90 - The Diamond Pits (Patreon)

Hey all! I'm working on maps for forthcoming Dungeon of the Week adventures. Next up will be The Diamond Pits. This big ol' map needs 10 or so awesome words. Leave a single word down in the comments below and I'll generate a room based on your prompt.

Usual rules apply:

1) One word per patron
2) Keep it clean
3) Nothing to anachronistic
4) The words "defenestration" and "mirrors" have been retired
5) No proper nouns

I'm looking forward to your suggestions!
