  Diamonds were formed by nature
under immerse heat and
pressure deep inside the earth
over 100 million years ago.
Throughout the ages, due to its
beauty and durability, the
diamond has symbolized love,
hope, romance, and eternity. Also,
the innovative designs of beautiful
diamond jewelry have captured the
hearts of men and women alike.

Before buying your dream diamond, learn
all about it through the 5C's.
   
 
Carat   Color   Clarity   Cut   Confidence
   
 
  Diamond weight is measured in carats. One carat equals 0.2 grams. A carat is divided into 100 points, so that for example, a 0.50 carat diamond is described as a "fifty pointer". Size is the most obvious factor in determining a diamond's value. However, two diamonds of equal carat weight can have difference values depending also on their cut, clarity and color. Larger diamonds are rarer and thus more valuable. When selecting a diamond, choose a size that suits you best.
   
 
  Except Fancy color diamond, diamonds are found in a range of colors. Colors are graded from D "Colorless" to Z "Light Yellow". The most common color ranges are "Colorless" (D,E,F), "Near Colorless" (G,H,I,J) are "Faint" (K,L,M). Subtle differences in color can dramatically affect a diamond's value.
   
 
  As diamonds are natural stones, they often contain unique internal characteristics, such as minute traces of other minerals, and/or non-crystallized carbon. The quality, size, color and position of these internal features together determine a diamond's clarity. The fewer and smaller the inclusions, the less they interfere with the passage of light, allowing the diamond to sparkle more brilliantly, thus increasing the value of the diamond. Diamonds are graded by highly trained and experienced diamond professionals, using 10x magnification. Diamond clarity is based on a scale which ranges from "Internally Flawless" (IF) to "Included" (I).
   
 
  Diamonds are cut into different shapes, round, marquise, oval, pear, heart, square, and emerald. One's choice depends on personal preference. Whatever its shape, a well-cut diamond with the right proportions will display the greatest amount of brilliance and "fire", which in turn increase its value.
   
 
1. If a diamond is cut too shallow, light escapes through the pavilion before it can be reflected.
2. If it is cut too deep, some light escapes through the opposite side of the pavilion.
3. When a diamond is well cut, light is reflected from one facet to another and then dispersed through the top of the stone.
