So fancy!

By Alethea Inns, CG Did you know that diamonds aren’t just round?  They are cut in all shapes and styles to suit any personality or occasion. With diamonds, a “fancy shape” is anything other than a round.  Usually, the rough diamond crystal is shaped as an octahedron – a three-dimensional shape with eight faces, much like two pyramids stuck together at their base.  When the diamond crystal isn’t the typical octahedron because of how it was formed in the earth or transported to the surface, diamonds are cut into fancy shapes to get maximum yield from the crystal. Fancy shapes

You’re likely familiar with the 4 C’s of Diamonds: Cut, Clarity, Color and Carat – however, there is another very important aspect of diamonds to keep top of mind: Sparkle! Sparkle, or Scintillation as it is also known, is the play of white and colored flashes of light seen when the diamond is viewed in motion.  Viewable with the naked eye, sparkle is the life of the diamond.

Virtual Facets: The building blocks of sparkle

By Marc Nanasi, NEI Diamonds We know that a standard round Brilliant Cut has 57 (sometimes 58) facets, so how come when you look into a diamond, it appears that there are hundreds of flashing geometric shapes? Those flashes are known as virtual facets, and collectively they dictate a diamond’s sparkle.

Because these facets work together to direct light, slightly tilting any facet

Considerations Cutters Take When Shaping Diamonds

Today’s blog post is written by American Gem Society member, By Marc Nanasi, from NEI Diamond professionals swear that Cut is the ‘C’ which has the most influence on a diamond’s beauty,and interestingly enough, it is also the only C that is controlled by humans (a diamond’s color, carat weight, and clarity are dictated from the rough stone found in nature). What most people don’t realize about cut is the extensive amount of consideration that goes into the cutting process.  Cut can influence a diamond’s value by up to 50%!
