Gem Cutting

Take a gem to the Gem Cutter in the hub and cut it. A good cut multiplies what the gem is worth. A bad one shatters it.

On average a cut is worth 1.45x the gem's value, before the fee.

How it works

• Pick one uncut gem from your backpack. The confirm screen shows the fee and every chance before you cut.
• The fee is 25% of the gem's current sell price, at least 1 coin.
• Shatter destroys the gem. The fee is still paid.
• Each gem can be cut only once, and you cut one gem at a time.
• Luck never changes the cut chances.
• A cut gem keeps its cut when you sell it or place it in your museum, so the sell price and museum income both include it.

Cuts, sizes and mutations

The cut multiplier stacks with size and mutations: all three multiply together. A cut gem shows its cut name next to its size and mutation, and your Index card records the best cut you have made of each gem.
