Gems

Gemstones can be mined in veins rarely underground and are very valuable. Their only crafting use is to forge a Phaseblade; however, they are worth a large amount when sold to NPCs.

Amethysts are the most widely available and cheapest gemstones mineable (coming in at a measly 5 Silver Coins each). They can be used to construct Purple Phaseblades.

Topazes are less common than Amethysts, and worth more (10 Silver Coins each). They can be used to construct Yellow Phaseblades.

Rarer than Topazes and worth more (15 Silver Coins each), Sapphires are only found towards the bottom of the Cavern Layer. They can be used to construct Blue Phaseblades.

Found only in the Cavern Layer, Emeralds are very valuable (30 Silver Coins each). They can be used to construct Green Phaseblades.

Rubies are the second rarest gemstone available (40 Silver Coins each). They can be used to construct Red Phaseblades.

The most valuable gem available (80 Silver Coins each) and the rarest, Diamonds appear only in smaller veins near the bottom of the Cavern Layer. They can be used to construct White Phaseblades.
