What are “fancy” diamonds?
There are two interpretations to the term “fancy diamond.” The most common use relates to cut or specific shape of the diamond. Fancy refers to any diamond cut other than round including: marquise, pear, oval, emerald, princess, radiant and heart shapes. The second fancy reference is to diamonds that have a prominent body color, such as canary yellow, brown or blue. Some diamond colors are much more rare and valuable than others. For example, diamonds are often found in shades of yellow and brown. But colors such as blue, pink and light green are uncommon. Deep pink is particularly rare.
