Jay the Jeweler stores some of his old pieces here.
I think that might be the worlds largest emerald?
The Hope Diamond (previously "Le bleu de France") is a large, 45.52 carats deep-blue diamond, housed in the Smithsonian Natural History Museum in Washington, D.C. The Hope Diamond is blue to the naked eye because of trace amounts of boron within its crystal structure, but it exhibits red phosphorescence after exposure to ultraviolet light. It is classified as a Type IIb diamond, and is famous for supposedly being cursed. It is currently unset for the first time since it has been on display.
Warning...lots of butterfly shots. Deal with it.
