Moissanite was originally born from a star. However, naturally occurring crystals are too small for use in jewelry. Using an uncommon combination of art and science, moissanite is now available on earth! ----- Original Message ----- From: "Tracy Latimer" <tracyl_at_lib.state.hi.us> To: <meteorite-list_at_meteoritecentral.com> Sent: Monday, June 24, 2002 1:44 PM Subject: [meteorite-list] Green meteorites > I've recently started branching out from meteorites (to the alarm of my > husband!) to semi-precious gemstones.
