Reply to needle, stylus, and cartridge

ok so i have two needles, i have a $40 numark one and a pretty much $90 shure whitelabel dj tt cartridge. And your probably wondering why they both different well its because i couldn't afford a second shure whitelabel tt cartridge. and the one thing i like about the shure whitelabel (besides the sound quality) is that on the retail box is says "Record wear : Ultra Low". so i will get a 2nd one when i'm able to afford to drop $90. anyways the point of this thread is to show you a pic of the shure whitelabel cartridge that i own (1) and i want to identify if the "stylus" would be the piece painted color blue. and the cartridge would be the piece painted color white on top of the blue piece? and then the needle is the little tiny stick in between the blue piece?

if this is wrong, can u identify for me, what is what [stylus and cartridge] i already know the needle is the little stick in the middle of the blue piece
