Bear with me for a moment. Many of us forget that fire is pure. We remember this when we need to use it for purification. Love is like fire. For it is also pure and burns with a most powerful intensity. Your combined carbon is symbolic of the love you share. When your fire (combined carbon) transforms into a crystal (your Heart In Diamond), this crystal is superior to any other kind. Its purity is unparalleled. It is closer to your heart than any other diamond can be. If diamonds are forever, let them be no less pure than love itself.
