Milky Quartz

A Houseki no Kuni fan OC! He was supposed to be moonstone before, but I thought that wouldn't work well as a name. ^_^''' Milky quartz looks very similar, it's milky as the name implies, and ranges between white, grey, and a very light color tint (I like pink) depending on the light or background. 

Personality
He's not a fighter despite his considerable hardness. Due to his dreaminess, most gems experience him as a very aloof and reclusive person.  However, he is naturally empathetic and the gems can come to him for his, unexpectedly so, quiet yet warm support. He'll always be able to listen to you while doing his work as he's an excellent multi-tasker. Milky Quartz is able to fight, but prefers to dream and quietly gather information and solve problems by himself or as the quiet company of others.

Language
Milky refers to himself as "boku"( 僕 ) which is a relatively polite yet masculine way to refer to oneself.
He will refer to his brothers as "niisan" or "oniisan" or just their name most of the time.
He uses slightly informal language most of the time.
