Facts about Diamond

28 Jan 02

Hello Everybody,

There were couple of queries in Fashion section as to how to buy diamonds, how do we know whether the diamonds we are buying are of good quality etc. In this newsletter, I would like to tell some important factors to consider while buying diamonds which will tell whether they are good quality diamonds or not.

Diamonds are one of oldest, famous and of course costliest stones available in market. So when you want to buy diamond you would want to make sure that what you getting is worth for what you are paying. Diamonds are recognized by their 4Cs, which are Carat, Color, Clarity and Cut. The 4Cs are used through out the world to measure the diamond.

Lets see what are those 4Cs how it affects the value of the diamond.


Carat refers to the weight of the diamond. Some people measure in Cents also.1 Carat has 100 cents or 100 points. If jewelry has more than one diamond stone, then they are measured by Total Weight (TW), which is the combined total weight of all the stones in the piece. Larger diamonds are very expensive as its difficult to find them. If we think that 1-carat diamond is twice as ½ carat diamond we are wrong, 1-carat diamonds are more than thrice the price of ½ carat.


Color refers to the degree to which diamonds are colorless. Most diamonds are colorless but will have some tint of yellow in them. The closer the stones come to colorless the more expensive they become. Diamonds are graded on a color scale ranging from D (colorless) to Z (heavily tinted.) Only a highly diamond professional will be able to detect any color in E or F stones, and the color in diamonds rated up to J will be virtually invisible when set in a ring or other jewelry.

Color is one of the 4Cs so if the color is not near to colorless, it can still be very expensive if they have good clarity and cut. How it is in jewelry also makes lot of different. If the stones are totally covered by gold then they will not shine because the yellow color of gold will reflect the diamond’s shine.


Clarity refers to the presence of imperfections in a diamond. Professionals call them as “inclusions”. They can be in the form of tiny spot, dark dots or feathery cracks that can be seen only using magnifying loupe. This tool allows jewelers to see a diamond at 10x its actual size so that inclusions are easier to see. The fewer the imperfection the more the stone will cost. If the imperfections are at the edges of the stone, mounting them on gold can cover them. Cracks from the surface to the interior are especially dangerous because the diamond could break if hit the wrong way. Here is a list of clarity grade that are commonly used in United States and most of the countries.

  • FL – Flawless (Free from all impurities which will be very expensive)

  • IF – Internally Flawless( No impurities visible at 10x insignificant surface blemish)

  • VVS1, VVS2, VS1, VS2 – Minor impurities

  • SI1, SI2 – Noticeable impurities

  • I1, I2, I3 – Obvious impurities.


Cut refers to the angles and proportions of a diamond. Based on scientific formulas, a well-cut diamond will internally reflect light from one mirror-like facet to another and disperse and reflect it through the top of the stone. Most popular cut are round brilliant cut.

The 58-facet round brilliant cut is the most popular because of its fire and brilliance. (These terms describe the intensity of the color and brightness of the light one sees in a diamond.) This is achieved by cutting the stone to very exacting mathematically-determined proportions so as much light as possible is reflected out the top of the diamond.

Diamond Care

Diamonds are hardest material on earth and only other diamonds can cut them. Though they are hardest material, they still require some care to keep them looking their best and to protect them from loss or damage. A regular professional cleaning is recommended. Diamond jewelry can easily acquire a buildup of dirt, oil, makeup and other materials that diminish its brightness, especially if it's worn every day. Diamonds also can scratch other gems or jewelry, especially soft items like pearls. And even though diamonds are hard, they can be brittle, especially along thin edges. Try not to wear your diamond when it might be struck sharply, and if you have an especially thin cut, keep it protected.

So now you now the 4Cs of diamond, next time when you are in jewelry store for diamond make sure that you ask the jeweler all 4Cs and get what is worth for your money.
