A Shanghai male friend i met back in the US University. He saved up his part
time work wage for a diamond engagement ring, that is about USD $10,000. He then
took his GF and future mom in law to a jewlery store to choose a diamond
ring, he later told us that he was very nervous if the ladies picked up a
ring over his saved budget. And it turns out fine, his girl friend only
selected a ring at half of his budget.
Now, they are happily married for years, with a house, and a boy and girl.
