Wasn’t there another topic about gifts for the yichud room in which many people said the whole idea was ridiculous? I think young couples shouldn’t spend so much on luxuries, especially when many (most?) of them are planning to be partially supported by their parents for a while. Unfortunately, people have been hoodwinked into the idea that certain gifts are required. The only halachic requirement is a wedding ring.
When my wife and I got engaged, I didn’t even get her a engagement ring. It wasn’t for lack of money, but because we thought it was unnecessary (and because at the time buying diamonds was tantamount to supporting apartheid). Years later, when she had a yen for a solitaire, she suggested CZ, which I was happy to get her.
