A diamond is hard, but would it chip if it's dropped on a hard floor from a chair? How rough can you treat a diamond when you wear it? |

Glass is harder than steel - it scratches steel. Hardness and toughness are different things. Diamond has very good cleavage in 4 planes or directions. Very thin girdles are prone to chipping. But most 100 year old diamonds are in identical condition to the day they were cut. Garry |
