TIFU by washing very important paperwork

Today I fucked up by deciding to wrap my girlfriend's diamond earrings. I took out the paperwork that showed the cut, clarity, color, etc. It looks sloppy in the box, so I put it in my sweatshirt pocket knowing I would just give it to her later. So then, we went out for dinner and I changed out of the sweatshirt. I had thrown the sweatshirt in the dirty laundry, and when I came back from our date, I grabbed the dirty laundry and threw it in the wash. Later on in the evening, I transitioned the clothing from the washer to the dryer. After the dryer was finished, I noticed a bunch of ripped and torn paperwork in the lint trap. My girlfriend was downstairs dying her hair, and So I asked her if she had maybe left some paperwork in her clothing that I had taken out of the dryer. She said no. So then I started to look at the paperwork, and as I started to open up the part that was legible, I realized it was the certificate for the diamond earrings. I yelled loud as hell "noooo, I'm so fucking stupid." My girlfriend stop when she was doing, and ask me what was wrong. I told her I couldn't tell her right now, and then I immediately tried to contact the company, but of course they are closed and won't be open until tomorrow. I'm hoping that they have my paperwork on file or at least a digital copy that I can provide her. I don't know if it even matters, but to me it does because I want her to know that her diamonds are her diamonds. She could tell I was overly upset, and she kept asking what's wrong, but I told her she'll know after Christmas. TL;DR I ruined paperwork for the proof of expensive diamond earrings I purchased.
