They cannot be sold to vendors, but can be auctioned or traded. They stack in 100.
Un'goro power crystal varieties
Power crystals can be used for various things:
You turn in 7 of each crystal to be studied by J.D. Collie.
Prior to patch 3.1.0, the Thorium armor set required various power crystals in its construction, and provided extra resistance to all magic types.
Since patch 3.1.0, this set have lost its resistance and require no crystals.
It may be significant that there are no silithid hives near the pylons except in the south, where a southern pylon is mysteriously absent.
Depending on which power crystals are combined, the pylons will provide quests that reward different crystal which can be consumed for an effect. Each quest reward 6 crystals when completed.
The Power Crystals of Un'Goro
Excerpt from "The Power Crystals of Un'Goro" by J.D. Collie
Amid the rocks and rich soil of the crater floor can be found all manner of colorful crystals, each as fragile as glass. Held to a light, they seem to flicker and glow like flames... They seem to have no useful purpose, or so I believed at first, until I found the first Crystal Pylon. Located in the east, guarded by the pterrodax, this humming pillar holds the same sort of runes found on the Stone Guardians as well as the hovering pylons that guard the entrance to the crater. All my attempts to decipher this ancient tongue have met with failure. And yet — the pictographs clearly show power crystals being used for something. A ritual, a spell, I do not yet know...
Although the crystals come in all shapes and sizes, I have classified them in four main colors: red, blue, green and yellow. I've never found anything truly in between these shades, so there are no orange or brown ones, for example. Anyone who isn't color-blind can tell them apart by a glance. What's more, I’m fairly certain the crystals can be employed by the Crystal Pylons. If I could figure out the right pattern — but how? How?
Much later in the text.
I've done it! I found one of the patterns! Or at least I’m pretty sure I have. I need to make another trip to the western Crystal Pylon to see. If this works, the crystals I've collected should coalesce into a single mega-crystal infused with the combined powers of all the shards! I can't wait to report on the results when I get back!

- A major plot element in Land of the Lost are the pylons, devices of unknown origin which open portals through space, time, and dimensions. They are powered and controlled though consoles comprised of patterns of red, green, blue, and yellow crystals.

In the Sholazar Basin, there are some strange devices on top of several pillars, on these pillars grow crystals which resemble the ones in the Un'Goro Crater. Their purpose is yet unknown, but the power of the pillars is readily apparent.
List of pillars:
- Glimmering Pillar (white crystals)
- Lifeblood Pillar (red crystals, destroyed)
- Skyreach Pillar (blue crystals)
- Mosslight Pillar (green crystals)
- Suntouched Pillar (yellow crystals)
The Cult of the Damned has been shown responsible for the destruction of the Lifeblood Pillar, and is also active on top of the Glimmering Pillar.
Conservatory of Life
There are three pylons located at the Conservatory of Life inside Ulduar, their purpose is yet unknown. It should be noted that they are unlike the pylons in the Un'Goro Crater which all share the same coloured crystal.
Mastery of the Crystals
During the quest quest:Mastery of the Crystals, Lightningcaller Soo-met gets the player to use crystals to defend the gorloc faction, the Oracles. They may be in connection with the Sholazar Basin power crystals. The crystals are gotten out of a chest.
