Precious stones

In The Witcher computer game

In The Witcher, there are several kinds of "gems", or precious stones. Most can be used as gifts or in exchange for goods or services:

• Amber
• Diamond  •  Diamond dust  •  Gramps' diamond
• Ruby
• Sapphire

Notes

• The teleportation crystal which Kalkstein gives Geralt in Chapter II is also labelled as a gem, but it can neither be bought nor sold as it is a quest item.
• The swordsmith off the Trade Quarter marketplace will require a gem before he reforges a sword. There seems to be no benefit from doing this, though.

In The Witcher 3: Wild Hunt

• Amber  •  Amber dust  •  Amber fragment  •  Flawless amber
• Amethyst  •  Amethyst dust  •  Flawless amethyst
• Diamond  •  Diamond dust  •  Flawless diamond
• Emerald  •  Emerald dust  •  Flawless emerald
• Ruby  •  Ruby dust  •  Flawless ruby
• Sapphire  •  Sapphire dust  •  Flawless sapphire

Notes

• Infused crystal  •  Infused dust  •  Infused shard
• Polished crystal
• Power cell

and pearls (both white and black).
