Redstone Ore

"You'll most often find redstone deep below the surface, in the bottom 16 layers of the map. Normally it spawns in large veins of 4-8 blocks, each of which will drop 4-5 redstone and some experience when you mine it with an iron or better pickaxe. You'll get more with a fortune-enchanted pick, of course."

- Duncan Geere

Redstone ore is the ore block from which redstone is obtained.

Natural generation
Redstone ore can generate in the Overworld in the form of mineral veins. Redstone ore attempts to generate 8 times per chunk in veins of size 1-8, from altitudes 0 to 15, in all biomes.

Breaking
Redstone ore can be mined with an iron pickaxe or higher, or it drops nothing. If mined with Silk Touch, the block drops itself. Otherwise, the block drops 4 or 5 redstone dust (or more with Fortune).

Light
Redstone ore produces light (strength 9) and red particles when clicked, updated, or contacted by any mob (exceptions being a sneaking player and spiders). This effect continues until the redstone ore block receives a block tick (averaging 68.27 seconds). This effect does not actually produce redstone power, but the block changes can be detected with an observer or a block update detector.

Subsequent clickings on a redstone ore block causes it to emit an extra burst of particles per click.

Trivia

 * In, armor stands cause redstone ore to have a block update.
 * Attempting to place a bucket of water on redstone ore causes it to produce light.
