I'm sorry, but my investor brain has completely killed of my consumer brain these days.
An engagement ring is a symbol of the fact that you are
getting married. You haven't actually pulled the trigger yet!
All you've done is announce a future event. Big deal. And don't have a pathetic engagement PARTY - same reason; big deal.
Spend a bit more on a nice ring for the ACTUAL event if it eventuates.
Many engagements end up in tears and single-dom.
So, why spend a fortune on a ring, which will never be sold for cap gain, will never have a rent return or a depreciation schedule, and is only important to the WEARER and no-one else?
Even the fiance (hopefully future husband) doesn't care what it looks like after about 2 weeks, but remembers the pain in the hip pocket for several years.
Pay attention: ENGAGEMENT RINGS ARE A TOTAL WASTE OF MONEY.
If you spend more than $1k on one; you are a very dumb male, and are out to impress others - who couldn't care less in reality. Or worse; trying to buy your bride's love. pleeeese!
The other female friends will oohh and aaah, but will secretly be jealous and resentful if yours (your wife's) is better than theirs.
Save your money, and get rich with the difference between what you were going to spend, and what I've suggested.
Your future wife will thank you. If she doesn't - get rid of her.
