Happy Valentine’s Day, Paula!
I wanted to get you the universe’s largest known diamond, but since it’s 2,500 miles across the ring would probably be a bit awkward. Still, a 10,000,000,000,000,000,000,000,000,000,000,000 carat diamond would be quite the accessory.
side note: at first I assumed this was some sort of bizarre typo in the paper, but then I did some additional research. Just google for BPM 37093 to find many more links. Thanks to OxBlog for the original link.
