I just noticed that there is a visible black dot in my diamond. I thought it was on the surface--therefore, I could clean it off...but noticed that it is in my diamond. Do you know what it could be? I am going to be taking it back to the jewelrer who sold the ring to my fiance.
Thanks.

If it is inside the diamond it is a carbon inclusion most likely and not uncommon at all.. Do you know what the clarity rating for your diamond is?? It may be exactly as sold to your fiance..

How long have you had the ring??

Before you take it back to the jeweler, see if the diamond has a GIA or AGS certificate, and if so, refer to the plot of inclusions to determine if the carbon (black spot) is shown.

I will pull my certificate tonight and look at the clarity ratings and the inclusion part. I will let you know what I find out. Thanks.

We only received an appraisal certificate from the jewelrer. He said that the two oval diamonds are approximately G-H VS quality...he did not mention anything else about the plot of inclusions. Should we have had another certificate??

rrebekah,

If the jeweler provided you with an appraisal then you may not necessarily have any other documentation (like a lab certificate).

From what you've posted it sounds like he has graded the diamonds as "VS", or "Very Slightly Included" clarity. Diamonds that are VS clarity generally require magnification before you can see the inclusions. It is possible, however, that if you look VERY CLOSELY (especially from the bottom or side) that an inclusion could be seen.

It is also very possible that his grading of "VS" was, let's say liberal. This means that a more strict grading institution (such as the Gemological Institute of America) may have graded the diamond lower.

Is this a new purchase or something you've had for awhile?

VS diamonds should not have eye visible inclusions. Go back to the jeweler and ask them to explain. It may be a piece of dirt on the back of the stone or it may be what is known as the 'bowtie' that you are seeing. In any case, the jeweler should be able to explain what you're seeing and to defend the VS grade. If they don't give you a satisfactory answer, seek out an independent appraisal and ask the same questions.

Thank you all for your replies. This is a new purchase---a little over a month. I never saw this before and I just noticed it a couple of days ago. I hope that it is a piece of dirt or something...because it is quite visible--even from a foot away. We are going to go to the jewelrer this weekend.

Hi rrebekah,

Don't get too excited yet.

It is possible that your diamond simply has a film on the back of the diamond which can make a VS type inclusion visible to the eye.

In which cases, a good cleaning can make it "disappear"

This film developing on the back of diamonds is very common as the oils from lotions, shampoos, etc. have an affinity for diamonds and is not easily removed from the back of the diamond.

This film may not even be noticible to you.

Bottom line, withhold judgement until you go to the jeweler and let them clean the ring for you.
