What kind of relationship do आप think was between pink, yellow, and blue diamond?

I thought there was a प्यार त्रिकोण, त्रिभुज between them. गुलाबी and blue diamond were together and yellow was jealous and shattered गुलाबी so she can be with blue is why she was trying to get her to forget about pink. but after seeing " Jungle Moon" after the way गुलाबी might have acted portrayed द्वारा Stevonnie, I think a maybe they could've had a mother-daughter relationship. what do आप think?
