Diamond Cut

The luster, glare and brilliance of a diamond all depends on a correct cut. Well cut diamonds are a direct result of calculated angles, proportions, symmetry, alignment and a fine surface finish or polish. Luster and brilliance are the most common words used to describe the effects of a diamonds cut. Luster refers to the rays which fall upon a diamond and reflect off the surface where as brilliance refers to the rays that go inside the diamond and reflect out.

Diamond Clarity

There are many different levels one looks at when finding out the clarity or imperfections of a diamond. Most all diamonds have natural imperfections, the less flaws the stone has the more rare  it is, thus making it more expensive. These imperfections are placed into two classifications, blemishes and inclusions. Blemishes refer to the surface flaws which include scratches, pits, and chips.  Inclusions refer to the internal flaws which include bubbles, cracks and non-diamond minerals. Superior Exchange has special staff that use a universal grading system, experience and proper tools when evaluating and pricing diamonds. You will always get top dollar!

Diamond Color

The color of a diamond is based off of a grade scale and refers to the lack or absence of color. This scale grades a diamond on how closely the diamond approaches colorlessness. This basically means that there are various shades of yellow and brown within most diamonds, the more yellow and brown tint you see the less valuable it is in most cases. This is an important aspect of evaluating a diamond and usually requires a trained eye with the proper tools and techniques.

Diamond Carat

Carat weight basically refers to the size of the diamond. The unit for weight measurement is the metric carat. One metric carat equals 0.200 grams. So basically if you have a 2 carat diamond it would be 2.00 grams. This would also be referred to as a 200 point diamond. A half carat diamond would be 0.500 grams and 50 points.


As you can see there are many intricacies to evaluating diamonds. By having a bit of knowledge you can see why to diamonds of exact size may vary greatly in value. This is very important in the buying and selling of diamonds. If you have additional questions about diamonds feel free to stop in or simply give us a call.

History & Background on Diamonds


~ How a diamond is formed:

  • Diamonds are formed 75-100 miles below the earth’s surface.
  • Diamonds are delivered to the earth’s surface by a specific kind of volcanic eruption.
  • After reaching the surface some diamonds settle back into the volcanic chimneys or pipes, which is generally where they are mined out of the earth.

~ Chemical composition of a diamond:

  • Diamonds are the only gems comprised of one single element.
  • That element is Carbon.  Most diamonds are 99.5% pure carbon.
  • Diamonds are the hardest gem known to man.

~ Where are diamonds found?

  • Diamonds have been discovered on all continents except Antarctica.
  • Large deposits of diamonds have only been found in a few places.
  • The “rarity” of diamond deposits contributes to their value.

~ World-wide Diamond Production

  • In 1991 about 104 million carats were mined from the earth.
  • Only about 46% were of “gem” quality.
  • There are many detailed and expensive steps a diamond goes through before it is a finished piece.
  • The biggest mines process 13,000 tons of rock and gravel everyday — to obtain just one carat of rough diamond.
  • All the extensive and expensive steps in processing are another reason why diamonds in a retail store are so expensive (valuable).
