How Accurate Are Jewelry Appraisals?

October 28, 2014 - Diamond Articles

When consumers buy diamonds and gemstones, they often gain a sense of confidence and security from the grading certificates provided by jewelers. But a new study by WP Diamonds, one of the world’s preeminent buyers of second-hand diamonds, quantifies the extent to which such jeweler’s appraisals tend to over estimate the color and clarity of the stones. We take a close look at the question: how accurate are jewelry appraisals?


What is a jewelry appraisal?

Many retail jewelers and local jewelers will offer an appraisal service. Appraisals are often done for insurance purposes or for peace of mind when buying a piece of jewelry.

They provide a detailed description as well as an estimated cost to replace. Appraisers charge either a flat rate for this service or a price depending on how long it will take them. A jewelry appraisal can cost $50-$150.

Study: How accurate are jewelry appraisals?

The WP Diamonds study, which was conducted during the second quarter of 2013, involved 220 evaluations by the Company’s graders.

  • Clarity: We found that the jeweler’s appraisals graded an average of 1.3 grades higher than the grade determined by our evaluation team, which relies on internationally recognized standards set by the Gemological Institute of America (GIA).
  • Color: Our experts also found that the color grades in these jewelry appraisals were approximately 1.9 grades higher than the GIA equivalent.”



For consumers, the takeaway message is clear:

Optimistic grading certificates from jewelers should be taken with a pinch of salt. When it comes to the returns consumers stand to receive in the second-hand diamond market when they sell diamonds, this is not the best way to accurately ascertain the stone’s value or characteristics.

What truly matters is the actual color and clarity of the stone as determined by a recognized diamond grading laboratory, such as the GIA, or respected experts, such as those here at WP Diamonds. Consumers should be circumspect, to say the least, about non laboratory grading certificates as they can give a very false expectation of resale value.”

We see the dialog with clients as one of the most important services we provide, because our goal is to help our customers make informed decisions.
