Yesterday we received a diamond from our International Selection that had an inscription that I had never seen in real life before.
\n<\/p>\n

Anyway, the inscription, as shown below means that this particular diamond is a Hearts on Fire<\/a> (HOF) branded diamond. I can only guess that we came across this stone because of the recent squeeze<\/a> in the US of HOF retailers. With many retailers having “dead stock” it is likely that at least a few of them sought to sell them through the wholesale market.<\/p>\n

\"Hearts<\/p>\n

Anyway, this particular stone was re-certified by the GIA<\/a>, as HOF are certified by the AGS<\/a>. What caught my eye was that GIA had given a polish grade of only Very Good<\/em> not the top grade of Excellent<\/em>.<\/p>\n

I knew<\/a> that AGS is a bit soft on polish. I even sent a few more stones that had a GIA Very Good<\/em> polish grade to AGS last year and obtained their Ideal<\/em> grade. Perhaps because they have a clarity grade of “0” which covers both Flawless and Internally Flawless on the GIA scale, they examine the diamond’s surface differently from GIA?<\/p>\n

Anyway, one of HOF’s main selling points is that they cut and polish their diamonds with a 100x lens. Now I’ve never used a 100x lens before (our microscope only goes up to 90x), but I would imagine that if the diamond was really cut with a 100x lens, then they would be able to see polish marks that the GIA picked up with a 10x lens. In any case, the diamond was very well cut, and the Ideal-Scope and hearts pictures are below.<\/p>\n

\"Hearts\u00a0\u00a0 \"Hearts<\/p>\n

One last thing that I found strange was that GIA mis-spelt Hearts on Fire<\/em> and left out the E in the Hearts<\/em>. This unfortunately is nothing new, as we have had instances of GIA’s administration printing the wrong certificate type and not laser inscribing the diamond.<\/p>\n
