Bio== As a young colt, Diamond Mines received a Rubik's Cube for his birthday. He was fascinated; he spent days figuring out how to solve it after he scrambled it. After a long time, he solved it without a guide. When he examined his flank afterward, he discovered a cutie mark in the form of a puzzle piece. He was surprised, for his special talent related in no way to his name. His parents (two earth ponies) named him Diamond Mines because they hoped he would take after their profession: mining. Throughout his childhood, he continued to solve all kinds of puzzles. Finally, when he grew up to be an independent stallion, he moved to Ponyville to own a puzzle shop; there he sells all kinds of Rubik's Cubes, jigsaw puzzles, and other mind benders.
@mlp_DiamondMine tends not to tweet as much as other ponies, but he does like to. Any time he's just lazing about in his shop, feel free to stop by; he's always looking for a good RP. His human lives on the east coast of the U.S., so he may not be online at the same time as you.
