Two weeks after I first talked to my future wife (we met online), and two weeks before we met in person for the first time, I dropped $2,500 on a certified diamond ring. The night I picked her up at the airport on our first live "date", I popped the question. Three months later, I moved all my stuff to Tulsa, we got married the week after that, and in November we had our 10th anniversary.
I think I passed the jewelry test.
A few months ago we attended an estate auction, and I let her bid on a gold and diamond ring (she asked first how much she could spend. She won at $400; we took it to a major jewelry store to have it inspected, and it appraised for $1,600-$1,800. As Gunnut07 said, it's money in the bank.
Fortunately for my wallet, my darling wife actually prefers costume jewelry for everyday wear. She has a ton of it, for every occasion.
But her Christmas gift from me this year? A LaZboy rocker-recliner. It's what she specifically asked for.
