Last week, we sent two GIA certified stones to the AGS lab. The reason being was that the GIA both gave them a “very good” cut grade, despite them being what we thought top stones deserving of a higher cut grade.

One of the things I’ve always wondered was how popular certain shapes of diamonds really are. So, I decided to gather statistics from our diamond search and see how many searches were performed on each shape.

A few weeks ago, we sent seven stones to the GIA in Carlsbad for certification. Six had our own “Jogia Grading System” certificates and one had a DCLA certificate.

In May, we wrote about the square hearts and arrows cut that we are now stocking. Since then, we’ve showed it to numerous people (funnily enough, mostly in the trade) who have all been amazed at the brilliance and sparkle of the Square Hearts and Arrows cut. (more…)

Correct me if I’m wrong, but no Australian diamond grading lab lists either the star length or lower half length on their certificates - something that both the GIA and AGS do on round brilliants.

On Monday, we received our first square hearts and arrows cut diamond. It’s just under a carat (0.87ct) and an F/VS1, with excellent polish and symmetry, as graded by the GIA.
