Ok but why?

I wanted to add a giant 64x64 diamond that would cost 1 million credits so that CEOs could flex the huge amount of credit they got.
Trilby told me she got it, but then made #1952, which is an anomalous crystal that's so valuable Lonestar can't find a buyer, which is the opposite of what I asked.
So I found those sprites on the internet and decided to do it myself.

TL;DR : It's a way for Lonestar to flex how much money they have by buying useless shit who's whole purpose is to allow flexing.
