I had a marquee diamond ring. I'd bought it from a divorced gal who needed the money to move back home. I was trimming cedar limbs and shredding them. That evening I noticed no diamond. I went out with a flashlight and looked all over where I'd been. No luck; I was sad about it but there was no sentimental loss in it; just the monetary part. The next day I got my things out to get to work again and as I pulled the small trailer out there it was; laying there as if saying "here I am". I was really surprised. I had it reset. I also lost the diamond in my engagement ring from my late husband; thankfully it fell out on the table. It's now in a zip lock bag to be repaired. Good luck with whatever you decide to do. It can be really upsetting.
