Gems and Jewellery
From OSE SRD
Gems
The value of each gem in a treasure hoard is determined by the following table:
Gem Values
d20 | Gem Value |
1–4 | 10gp |
5–9 | 50gp |
10–15 | 100gp |
16–19 | 500gp |
20 | 1,000gp |
Jewellery
Each piece of jewellery indicated by a treasure type is worth 3d6 × 100gp (or more, if the referee wishes, for characters above 3rd level).
Damaged Jewellery
Rough treatment of jewellery (e.g. crushing, intense heat or fire, lightning) can damage it, reducing its value by 50%.
Combining Values
When a treasure type indicates the presence of multiple gems or pieces of jewellery, the referee may combine the values, as desired. For example, a roll of five 50gp value gems may be placed as a single 250gp gem, a 100gp gem and three 50gp gems, or any other combination.
