The reality of colored diamonds at Leibish

Leibish Polnauer, President & Founder of Leibish said, As you might imagine, we often receive calls from jewelry appraisers seeking to know the replacement value of fancy color diamonds purchased years back.

As an example, here’s a recent mail we received. I’m a fine jewelry appraiser in Walnut Creek, CA, working on an insurance appraisal. My client has a GIA certified natural round brilliant diamond .70 ct, Fancy Intense Purplish Pink, even color, with medium blue fluorescence, which was purchased 20 years ago.

I’m trying to research the current replacement cost for a comparable diamond, wholesale. That’s a complex question, and in this case more needs to be disclosed to accurately estimate its current value. What is the clarity? Is the stone an Argyle Pink, and if so, does it have an Argyle report with an accompanying original laser inscription?

Soaring Values & Provenance, Color diamond and gemstone values have risen dramatically in the last 20 years.  A 0.70 carat intense pink diamond with VS clarity around 20 years ago costing $50K per carat may cost $350K per carat now; providing if it has an original Argyle inscription and certificate.
