>>113609927A theory/idea I happen to quite like is that we already know what Blood Diamond, or Red Diamond, looks like and acts like.
It's Pink.
How does one get pink? You add white to red. Pink's quite the bright shade, far from bland; she's got very little white in her, just as White has very little pink in her.
The idea is that when White was splitting Pink off herself, she didn't do it quite right, and the result was two gems with imperfections, aspects of each other.
White clearly represents what can be best described as an authoritarian desire for well-being and safety of her Empire. No matter the cost, the rules must be followed, Gems must obey and do as told, even her fellow Diamonds.
Perhaps, she wasn't always this brightly and over-the-top excessive? Perhaps, when she split Pink off, the bit of Red Diamond's essense, the essense of a Diamond that stands for passion, for strength, power, determination, it all influenced the way she saw and did things.
Meanwhile, Pink is a mess. She's tiny - so tiny, in fact, that the discoloration made her entirely pink instead of red with a slight bit of red.
On one hand, she demands a colony. She demands to be seen as an equal, but she can't act fittingly. She's supremely powerful, but can't control herself. She lies, grasping control of her friends, even if for their own good. She genuinely engulfes herself with ideas - her own colony, freedom for Earth, becoming something entirely new, all that.
All because White's striving for perfection, for safety, for authority and for excellence mixed with Red Diamond's bright passion, passion that White didn't want in her - maybe it made her too emotional, and she felt the need to harden her heart.
Pink really is an odd one out. Unstable, awfully powerful, prone to outbursts, her very being seems to swing from one persona to another.
Maybe it's because there's not one, but two driving natures in Pink.
