Blue Magma and a diamond dimension

i think Minecraft makes it to easy to get diamonds so this idea is that they have to make a portal surface out of iron and make a copper and steel to light it and go into a diamond dimension and you need a iron pickaxe to mine some diamond ores which are really rare and to smelt them while if they mine the floor its like bedrock but diamonds and there's acid for the lava in the dimension I would love to see some concepts and this update come to life even if its an addon for free i would love to see it and make some stuff out of emerald and more stuff for diamond :) and also i would love to see mobs and hostile mobs and even a boss for it
