Verification is what we do in our gem lab on a daily basis. Often the paperwork or certificate from a gem lab does not match the stone that accompanies it.
We ‘call them as we see them.’ This past week we examined a diamond ring with a certificate grade for the stone of SI-1. While we agreed with the color grading, we determined the clarity to be SI2 – 3. This meant that the owner had received a lesser quality stone than he thought he was buying.
With the information we provided, he was able to return the stone to the jewelry retailer in exchange for a better quality stone with a GIA certificate – the more trusted grading laboratory.
This type of discrepancy happens more and more frequently so Buyer Beware – Trust but Verify. Here is a helpful link to a news network broadcast:
