diamond engagement ring takes place back into it?

my engagement ring is an heirloom and when I have had no defects. has been last for 3 people (me being the third) and I had to get back to size and clean the first time I got in January. (I've been engaged for 2 years but finally got a nice ring), also one of the fixing loose ends. but I have recently started to notice a fault. and I know that did not exist before. i have checked this thing with a magnifying glass. its got a dark gray spot on it. could be from where it is fixed or cleaned? I remember that after being there so I have the jewelry back. ring greatly appreciated because it is older and flawless. It is also a full caret. but the error that concerns me … diamonds do not get old as defects or not? could something have happened to her?

Oh, no! I hope it was not a diamond exchange as part of the answer people have suggested. When my wife and I had to take his ring for a set of pins, took the original certificate and the bond of 20x and examined the diamond in the front jewelry that will show that the inclusion saw through the loop matched the certificate. Anal was my way to let you know that I am sooo familiar with my wife's diamond. Pulled the loop gain and also compared. Therefore, it is both on the same page that brought the diamond matches the certificate store. 3 days later when we got the diamond, the jeweler and diamond compared with the certificate once again. Everything matched. If your case is not an exchange of diamonds, please understand that Diamonds are magnets for grease. Try taking a baby's toothbrush very smooth with a bit of liquid Dawn and clean the diamond under hot water. Then rinse with distilled water. Very important to use distilled water * * because tap water has minerals and tends to point up on the diamond. It is very rare for a diamond that are damaged by heat or stress mechanics and that diamonds are a very hard substance. However, the waist of a diamond, if thin, is very vulnerable to spring. You did not mention if the spot you see is near the waist or table. Good luck! * * *
