Do diamonds measure smaller after they are set?

Thats a huge difference! Yes, it is very difficult to measure a diamond while set. It’s not necesarily smaller or larger, just more inaccurate because prongs get in the way and its hard to measure height. 

But I’d be pretty upset if its measuring THAT much smaller. Maybe get a second opinion (appraisal) just to be sure.

No – they should measure between the prongs; measuring a stone that is set can be less accurate, but this is a big jump. You May want to have the stone co pared to the certificate (look for inclusions, etc) to confirm you actually is the certed stone.

I think she measured your ring wrong. It’s a big stone. I would trust the certificate and if you’re really worried, set up an appraisal appointment with a different jeweler.

catqueen92 :  the measurements and finger coverage look a lot different. Is it certified? If it’s insured I would suggest calling the insurance ASAP. If it were switched, the hazard of taking it to another jeweler is then the original jeweler can blame the 2nd jeweler.

catqueen92 :  The measurements should not change with resetting. Do you have it insured? If so, you should call your insurance company and explain the situation. If the stone was switched, that is fraud. Since it is IGI certified, it should be laser inscribed. Did the jeweler you took it to show you the inscription when you dropped it off and picked it up? He/She should have. 

It it was switched, there’s sometimes a clause that will cover it (similar to if it were stolen), so the insurance would have a vested interest in recovering it.

Also you can measure it yourself with a caliper like this one. Since it is round, it should be fairly straight forward.

I think she measured wrong. It definitely looks larger than 6.7mm. I have an almost 7mm (6.98) and yours looks way bigger

catqueen92 :  I have a 1.65 that measures 7.51 x 7.53 and wear a size 6.  It’s obviously hard to tell from pictures, but I think your diamond looks very similar to mine.  Can you ask them to check for an inscription or compare the plot on your cert?

 It sounds like she may just have measured it wrong. It your stone the right picture? It looks much bigger than a carat.

Hold up.. red flag.  

1. it should have been measured before it was set [unless they were lazy and forgot to do it prior]

2. there should never be that much of a difference in size

3. you need a picture of the measurement while loose and of the weight to get to the bottom of the problem-even if they need to pop it out.  Because if that stone is not what you paid for-that’s a completely different rampage.  Hell hath no fury like a woman that has been lied to about her diamonds.. keep us posted!
