When a Diamond is cracked the signs are usually easy to see.
It will usually either look like it's broken into two sections, one side being a clean beautiful Diamond, the other side looking like a piece of salt...
Cloudy
Or you'll see a huge white cloudy piece darting it's way into your stone like a fault line in an earthquake. But sometimes you'll just chip the edge and actually take a chunk out of the side, those type of breaks you can actually feel with your fingertip if you run it along the Girdle, the Diamond's edge.
So now that we've decided what you have is not a crack, What now?
Clean your Diamond
Buy an Ultrasonic Cleaner!
Simple as that! If you clean the dirt and debris off the bottom of the Diamond, get rid of that grudge and grime and fingerprints, it will shine like the day you bought it.
If it makes you feel better, take it back to the Jeweler and scope it. Chances are, a good cleaning will make everything all right.
So what about the people that believe the Jeweler really did sell them a cracked Diamond? Now that you see this "cracked" inclusion and know it's there, you'll always see it. I would truly believe that when you bought the Diamond, you probably weren't too concerned about scoping the Diamond and looking for inclusions inside it.
You get what you Paid for
It's probably either an SI2 or in the I Clarity range. The Jeweler wasn't pulling the wool over your eyes, they were not ripping you off, they were selling you a Diamond that at the time, you didn't pay much attention to!
You get what you pay for! It's true! Read on...
