The 4 C's
Cut is a feature that reflects the beauty and brilliance of the diamond, and usually determines both the value and price. A key factor when making a diamond purchase is cut, as one may decide to compromise on clarity, size or color, but never on the cut. You must always ensure that you have the most ideal cut diamond.
Over the years, with advances in modern technology, based upon Tolkowsky's formula, the ideal range was developed.
Clarity refers to the extent of birthmarks or "inclusions" in the diamond. Most inclusions are not visible to the naked eye and can be viewed through a 10X magnification device.Inclusions interfere with the dispersion of light and affect a diamond's brilliance. With fewer and slighter inclusions, the stone is both rarer and more valuable.
Clarity is graded on a scale that ranges from internally flawless (IF), very very small inclusions (VVS1-VVS2),
very small inclusions (VS1-VS2), small inclusions (SI1-SI2) to imperfect (I1-I2-I3) with obvious visible.
The Color of the diamond could range from colorless to yellow:
To the untrained eye a diamond, which at first may apPear colorless, can in fact have traces of yellow and brown colors in it.
Colors, range from "D" grading (as the most colorless) to "Z" grade (as the closest to fancy yellow).
The closest to colorless a stone is, the more valuable the diamond is.
Out of the 5 C's Carat is the easiest to determine. Carat is actually a measurement of weight rather than size. However it should be relative to size as well.
One carat is equal to 0.20 grams (weight). In the diamond industry "1.00 carat" is divided into 100 "points", so for example a 70 "points" diamond weighs 0.70 carats.
The most popular diamond shape with maximum brilliance.
Rounded corners and larger facets to increase brilliance.
Often described as a square emerald.
Rectangular cut with its long, lean lines.
Unique unmistakable symbol of love.
Elliptical shape, based on the brilliant cut.
Football-shaped cut, create the illusion of greater size
A hybrid cut shaped most like a sparkling teardrop.
Square or rectangular cut with numerous sparkling facets.
Has angled corners,range from square to rectangle.
Conflict diamonds are diamonds illegally traded to fund conflict in war-torn areas, particularly in central and western Africa.
The United Nations (UN) defines conflict diamonds as "...diamonds that originate from areas controlled by forces or factions opposed to
legitimate and internationally recognized governments, and are used to fund military action in opposition to those governments, or in contravention of the decisions of the Security Council." These diamonds are sometimes referred to as "blood diamonds."
Hearts & Arrows
Hearts & Arrows Diamonds are precision cut variations of the traditional 57 faceted round brilliant cut.
They are cut to "ideal proportions" with superior optical symmetry, polish and a specific faceting pattern.
When all these factors are in harmony the result is a repeatable, near perfect pattern of eight symmetrical arrows in the face up
position called 'crown' and eight symmetrical hearts when viewed in the table down position, called 'pavilion'.
