### Expected behavior
Loot chest should have Pearl gems or whatever the highest metadata of the gems are.

### Actual behaviour
Seems like the loot table is assigning gems of a metadata of 48, which I'm just assuming was a typo as the highest metadata gems go up to 47.

### Steps to reproduce the problem

1. Use a loot generator or find desert temples/abandoned mineshafts (I'm using Cyclics creative loot generator)
2. Some of the chests will have normal gems from metadata 1-47, and one might have the invalid entry.

Looking at my code, it does seem to be doing 0-48 instead of 0-47. Easy fix.
