how many diamonds did we get approximately from the last 1.5 patch?

i want to save up for the next patch for obvious reasons but the current 4 stars are just so cute!! the plan is to wait and see how the 5* will look like before i pull anything of course, but i still want to calculate how much i would have by then, yknow, in case it’s enough for both the clock witch 4* and one of the 5* of the double banner. lol

how many diamonds did we get at 1.5? 2k? 3k?
