I did a blog post in January on synthetic diamonds moving into the jewelry pipeline. Both Gems and Gemology (the publication of the Gemological Institute of America) and Rapaport are full of articles lately on synthetic diamonds. It seems that synthetic diamonds are very appealing to Millenials for several seemingly good reasons. “Lab created diamonds… Read more »

SYNTHETIC DIAMONDS IN JEWELRY

Posted by & filed under Blog.

Synthetic diamonds are diamonds grown in a laboratory rather than being found (i.e. mined) in nature.  They are real diamonds.  They have the same chemical composition and crystal lattice structure as those found in nature.  But they are grown in a laboratory using one of two different methods.  The High Pressure High Temperature (HPHT) method… Read more »

What’s The Difference Between an Appraisal and a Lab Report

Posted by & filed under Blog.

I have customers who confuse laboratory certificates with appraisals and that is entirely understandable.  A laboratory report is independent, third party verification that the gemstone in your jewelry (ring, for example) is, in fact, really a (for example) diamond; that it has the measurements and carat weight specified in the report as well as the color, clarity… Read more »
