Sparkle... that's what diamonds do best! No matter if it is a 100-year-old diamond ring like this one, or a diamond cut with 21st century computer-aided technology, the sparkle of a diamond is what distinguishes it from all other gems.

The diamond's cut has the most effect on sparkle. Cut refers to the way a diamond is proportioned and finished to maximize light reflection and refraction.

When buying a diamond, look for a combination of brilliance (or liveliness) and fire (a rainbow of colors) which make up the diamond's sparkle. Most importantly buy the diamond that "speaks" to you.
