Ok, here’s the theory
So, you all have seen the original great Diamond Authority logo. It has a white diamond on top, a yellow diamond on the left, a blue diamond on the right, and a pink diamond on the bottom. Well, after pink was “shattered” the logo was changed. This time there was a white TRIANGLE (that’s important) on the top, a yellow triangle on the left, and a blue triangle on the right. But the most interesting part is the middle. In the middle, there was a small black triangle. This small black triangle is the most important part, but let’s break this down.
1.the diamond symbols were changed to triangles
2.they kept the same places on the logo as the original logo
3.there is an absence of pink (for obvious reasons)
4.there is a black triangle in the middle
5.the black triangle is smaller than the others
6.a diamond has 4 sides and a triangle has 3 (this sounds stupid but trust me, that is important)
Ok, now that that is covered, let’s move on. My theory is totally based on those two logos. If the diamonds added a small black triangle, they obviously had a reason. A reason for it being small, and being there in the first place. Now, pink diamonds symbol was not smaller than the other diamonds symbols and whites was not bigger than the others, so why would the black symbol be smaller than the others? Simple! Black diamond is INCUBATING! I know that seems like a stretch, but we know from reality that it takes a long time for diamonds to form, and Rebecca takes a lot from reality. Diamonds may actually take a very long time to be created in the show. Now you may ask, “where is the proof? How do we know that it isn’t just the symbols crossing over each other?” Well, notice the symbols shapes. They aren’t diamonds, but triangles. Remember how I said that diamonds have 4 sides and triangles have 3? Turns out it wasn’t stupid! 4+4+4=12 and 3+3+3+3=12 simple math. Well, they have the same answer. 4 is the diamond sizes and 3 is the triangle sizes. There would be 3 diamonds but there are 4 triangles. If you take a side from every diamond, you can make another triangle! That triangle is black diamond. Basically, white yellow and blue each gave up a bit of their power to create a new diamond, who’s power when born will already be at par with yellow and blue based on the symbol. We know that she isn’t out of incubation because the logo with her incubating is still the current logo.
