If diamonds are the hardest substance, how did mine break?
Even though a diamond is the hardest natural substance known; that does not mean it will not break! Diamonds have a grain that is visible under a microscope and are subject to break at this point. Diamond cutters are trained to find these breaks and chip or break off pieces along precise angles based on the crystal structures of a diamond. Diamonds are uniquely resistant to extreme heat and scratching, and can be cut and polished only by another diamond.
An extremely hard blow to the girdle, or any susceptible angle, will cause the diamond to chip. You can keep your diamond intact for a lifetime by having it set in a relatively protective setting, and visiting your local jeweler to have the prongs checked.
Diamonds are hard (resist scratching) but also brittle (prone to breaking). Breaking and hardness are not the same thing. Keep in mind that scratches are what dull the finish and luster of anything from a diamond to the paint job on your car; and a diamond’s ability to resist scratching is part of what gives them their eternal beauty.
