A Japanese man wanted to give his fiance a piece of himself when he proposed, so he saved his fingernail clippings for a year then ground them into a fine powder, and processed them into a diamond.
The man didn't stop at just making the stone from nail clippings, he also molded the ring setting from nail clipping powder and then covered it in silver.
He documented the whole process and posted the video on YouTube, which has since gone viral.
