Diamonds, like everything else, are available on the Internet. But diamonds, no matter where you buy them from, must be purchased from someone you trust. Even a face-to-face purchase can result an in expensive mistake – despite a certificate being provided. This is because all diamond certificates are not created equal. Some certificates represent grading that is not as strict as it should be. For example, a ‘G’ colour may be passed off as an ‘F’ colour, or an ‘SI1’ clarity may be passed off as a ‘VS2’. Stittgen can provide certificates of the highest standards such as those issued by GIA.
Unless you have a jeweller you trust implicitly, it is best you acquaint yourself with the basics of diamond grading. Below you will find a brief video on each of the 4C’s.
