Dreamstones

Gemstones, in addition to their mundane physical properties and beauty, hold great value in the Feywild as physical manifestations of dreams. It is said that a powerful and pure dream can create a mote of power that slowly grows and soldifies as more and more mortals have similar dreams.

Types of Dreams

Each color of gemstone correlates to a different dream subject, and are useful in the creation of magic items and as a way to power spells. For example, red gemstones are associated with blood and beasts, and black gemstones are associated with dreams of death. A very dark red ruby might be a dream of violent bloody death, and make the perfect reagent for a violent combat spell.

Topaz

Topaz tends to be useful for magic that abjures, protects, and wards. It is most useful for protecting against something when its color matches the target - orange topaz are used in warding off heat, for example. While other gems may be more effective, topaz finds its niche is being used as general purpose warding for arcane experiments and magical creations. 

Diamond

Diamonds tend to be a dazzling transparent that reflects many different colors when held in light. It is said that it is the manifestation of pure dreams, and can be used for all sorts of magic. This sort of gem is incredibly useful when attempting the most difficult magic, like resurrection. Other gems used for the same purpose can have unintended side effects - a flawless star ruby for example might be able to be used for resurrection, but the lingering power of dreams of blood might cause the resurrected individual to become more beastlike than they were originally. A diamond's clarity allows it to reflect the mage's true intent.
