How Well Do You Know Your Diamond?

by Admin 13. February 2015 10:02

Have you ever left your diamond ring at a jewelry store for repair?

If so, did you have a little twinge wondering if it would be alright? You may have heard a story about a jeweler switching stones.

Most jewelers are very honest and these things rarely happen, but how do you protect yourself?

The best way is to know what your diamond looks like under magnification.

Diamonds may have inclusions (internal characteristics) and/or blemishes (external characteristics). Basically it is anything you can see within or on the surface of the diamond.

For example, you may see something that looks like a feather, or a cloud, or a light or dark crystal. 

These characteristics are like a fingerprint. They never change.

If you have a laboratory certificate, you will see a plotting which is a drawing of the inclusions and blemishes.

If you don’t have a laboratory certificate, a qualified appraiser can do a plotting for you on your appraisal.  Usually a plotting is done on diamonds one carat or larger, and is generally not done for a diamond that is highly included.

Some diamonds with laboratory reports have a laser inscription of a serial number on the girdle. The girdle area is the outer perimeter of the diamond.  This is an additional layer of protection however, if someone was motivated, the serial number could be polished out. The only thing that never changes are the inclusions and blemishes.

So, hopefully, you are working with a jeweler you know and trust.  But if you’re are working with someone new, or have any concerns, ask them if you may see your diamond under the microscope before you leave it, and when you pick it up.  You can compare it to your plotting, or if you don’t have one, just remember one of the prominent characteristics so that you will feel more secure.
