I'm the same with earrings KMJH!
FH bought me a pair of diamond earrings once and I lost one while we were on holiday

He also bought be pair of the most beautiful Tiffany earrings but I lost one of those too. I still have the lone earring and hope to pair it up again one day.
When I lost the diamond earring, I didn't tell him right away as I thought it was just in the bottom of my suitcase (we were overseas) then when we got home, I never found it.
One day, he was onto me, and he asked where they were and I freaked out, went to my jewelry box and pulled out a pair of CZ earrings.
Sadly, my fib failed miserably: If the CZ's were diamonds, they would be around 3 carats each! He has never stopped teasing me about it

Suffice to say, I probably won't ask for diamond earrings again!
