Diamond Details

Here are some suggestions to consider when meeting with a professional jewelry consultant, at a jewelry store or with a wholesale jeweler.

What does clarity mean when it comes to diamonds?

Does the way the diamond is cut make a difference?

What colors are there for diamonds?

What are carats?

There are certainly finer points to consider, such as levels or degrees of clarity, sizing, finish and the actual size, style and weight of the diamond.

When purchasing a diamond, you are buying a seemingly indestructible piece of the world, which has been carefully mined from selected places in the earth. A diamond is a rare part of history. The history of the world and hopefully your shared history in a special relationship with your significant other, whether it be a husband, wife or life partner.

Some diamonds are clear and totally transparent, while other may be slightly cloudy or have a minor haze, with options for increasing opaquness. More opaque diamonds allow less light to shine through them and are usually priced at a lower cost than translucent diamonds. The more translucent a diamond is the more easily light can pass through it. Diamonds with blemishes of inclusions of imperfections are itemized according to a classification chart.



Among the more popular diamond shapes are:
  • asscher
  • bouquet cut
  • brilliant (cone)
  • cushion
  • emerald
  • halo
  • marquise
  • oval
  • princess
  • pear shape
  • cushion
  • trillium

Diamonds exist in a variety of colors. Diamonds may appear as being steel gray, white,blue, yellow, orange, red, green, pink to purple, brown, and even black.

Diamonds are sold by the carat, which is actually a unit of weight (ct. carat total, ctw: carat total weight).  The difference between carat total and carat total weight can be reviewed on Beyond 4 C’s.

A carat does not mean or determine the size or shape of the diamond. The word carat comes from Italian ‘carato’, which comes from Arabic qīrāṭ قيراط, in turn borrowed from Greek kerátion κεράτιον ‘carob seed’.  The carob seed was the original unit of measure for ancient diamond traders, because the mass was believed to vary only slightly, typically 5% or so. A carat is equal to exactly 0.2 grams (about the weight of a paper clip). A carat is divided into 100 points. A diamond weighing 50 points, is the equivalent to 0.50 carats.

The metric carat, was adopted in 1907 at the Fourth General Conference on Weights and Measures,[1]and soon afterwards in many countries around the world.[2] The carat is divisible into one hundred points of two milligrams each. Other subdivisions, and slightly different mass values, have been used in the past in different locations.

In terms of diamonds, a paragon is a flawless stone of at least 100 carats (20 g).[3]
