How do you sparkle?

By Amanda L. Colborn How do you sparkle? 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.

Can Crazy be the 5th “C”?

By Katie DaCosta, Craig’s Fine Jewelry   I remember learning about the 4 “C’s” long before I had any business thinking about diamond rings. Years later, my college roommates and I would spend hours on Tiffany’s website, driving ourselves crazy, creating the perfect ring. At that point, it was so much more about the ring than the guy. Did any of us know what type of Ramen we were eating that night? Nope. But we knew what we wanted our rings to look like and that was enough for us.

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