What Are Dirty Diamonds?A dirty diamond is one of two things: a rough diamond, or a diamond that hasn’t been cleaned in a while. Rough diamonds are uncut and unpolished – hence, they are dirty. But that type of dirty diamond will soon be cut and polished and sitting in a beautiful jewel box in a display case. Then someone will purchase it, and before long, it will become a dirty diamond once again.
Jewelry stores often run ‘fluorescence’ scams to varying degrees. Referring to a diamond as a blue-white diamond is such a scam. A blue-white diamond sounds very unique and special, but in fact, this type of diamond is of lesser quality even though the jeweler will try to make you think you are getting something special. Jewelry stores also like to show their diamonds in bright lights. Lights make diamonds shine. Ask to see the diamond in a different, darker type of lighting as well.Some truly unscrupulous jewelers target those who want appraisals on diamonds that were given to them as gifts or that were purchased elsewhere. They will try to tell you that the diamond is worthless, or worth less than it actually is worth and offer to take it off your hands or trade it for a much better diamond, along with the cash to make up the difference. This is called low balling. Get a second, third, and even a forth opinion before taking any action.
