Hearts & Arrows Formation and Grading

In April 2004 Brian Gavin of Whiteflash.com presented his grading system for Hearts & Arrows optical symmetry at the First International Diamond Cut Conference in Moscow, Russia. It was hoped that laboratories and peers would unite to maintain higher standards for manufacture of diamond sold as "Hearts & Arrows." Though laboratories do not offer a grade for Hearts & Arrows, Whiteflash does, and safeguards buyers of the 'A Cut Above' brand with a guarantee of optical symmetry meeting the IDCC presentation criteria. - Here is Brian's presentation on the Formation of Hearts and Arrows

How the Hearts are Formed
Below are views of Hearts & Arows being forming during the cutting process as they would be seen through a regular Hearts & Arrows Viewer. The leftmost photos show the diamond blocked in 8. The center pair shows the pavilion fully cut, with crown still in 8. The pair on the right show the fully formed Hearts & Arrows when pavilion and crown have both been finished.

Very cute! I liked this blog. Thanks for sharing this sell diamonds inspired type of article. Thanks a lot!

As a man I like to wear simple and sober rings, I am the men who is fascinate about diamond so I prefer single diamond ring rather than ladies style designer rings.

I never thought that gemstone rings will look so shiny and sparkling like diamond or gold.

Thomas Stevens said...

Brian Gavin certainly has had the right attitude toward diamond quality as can be seen from this article way back then! His new company has even made it onto the list of the top 10 diamond websites see Where to buy diamonds online.
