Have you ever cracked a diamond? It sucks. Of course the diamond will lose its value. Many people though see a little gash in their diamond and they assume they have cracked diamonds. Do not be so quick to make a conclusion. Be sure you know what cracked diamonds look like before you decide that the diamond you have at hand is cracked. Better yet, bring it to a jeweler to check if you really have a cracked diamonds problem at hand. I once thought that I cracked the diamond on a ring given to me by my grandmother because I am really clumsy and it would not come as a surprise if I cracked up a diamond or whatever hard surface. So I brought it to the jeweler and he was nice enough to explain how my diamond was not really cracked at all.If you opt not to go to the jeweler yet, at least read this article on cracked diamonds: www.jewelry-secrets.com/Diamonds/Is-My-Diamond-Cracked/Is-My-Diamond-Cracked.html
