No rank, then Bronze and Silver with three divisions each, Gold and Platinum with four, and Diamond with five before Crystal. That is the game, not a rounding: the tiers genuinely have different numbers of divisions, and this page prices every division separately rather than assuming they are uniform.
Crystal is the only position with a visible rating rather than divisions, and it is what almost everybody on this page is actually buying. The single step from Diamond 1 into it costs about three times any other division, which is an honest reflection of how much harder that climb is.
Square Enix does not publish the Crystalline Conflict tier crests anywhere we can legitimately source them, and drawing a lookalike would be passing off somebody else’s mark. So each rank renders with its own name and colour on a plain shield. The rank you are buying is exactly the rank named on it.
