engagement ring help


so my boyfriend told me to start looking at kinds that I like so that when I least expect it, he can do the damn thanggg😊 lol anyways I told him I want something cheap off Amazon that I don't want a lot of money spent on it just like a wedding I don't want to spend a bunch on that either. so I found this, what do you ladies think?? I don't want anything over $100 but I like that shape & all of it... any help or input would be nice! nothing rude though!!
