1. BUYING VALUABLE DIAMONDS
Diamond evaluation consist of the four C’s - Color, Cut, Clarity and Carat which were
formed by the Gemologist Institute of America (GIA). This structure was designed as a
standardized diamond rating and evaluation system that has become the norm within
the jewelry industry.
Below are the details on the significant factors to help navigate you through purchasing
diamond wedding bands and how to use the four C’s that is help in your diamond
assessment.
Cut- Most people confuse the cut of a diamond with its shape, these are two separate
entities. Though some shapes, primarily round, have more ideal proportions that give it
more brilliance, the cut is basically how cleanly and accurately a diamond is made to
bring out its sparkle and shine. How well a diamond is cut is the main reason for the
diamond’s brilliance.
Clarity- Diamond clarity is simply the amount of inclusions in a diamond. Diamonds can
contain many different types of inclusions, depending on the type of inclusion it can
affect the light return of a diamond, therefore diminishing the stone's value. Evidently
the cleaner the diamond the more valuable it will be. Inclusions are one of the most
important factors when it comes to gem valuation. Diamond clarity ranges on a scale
from IF-internally flawless (no visible inclusions under 10x magnification) to I-included
(eye visible inclusions).
2. Color- The color of a diamond or absence thereof is another factor that you need to
consider before buying a diamond. The more crystal clear and colorless the diamond
is the higher quality it has along with a high price. Though, the color does not affect
the brilliance of a diamond, the more preferred diamonds are the colorless ones that
truly show off a diamonds scintillation or “fire” which is the full spectrum rainbow
effect you see as light returns out back through the top of your diamond. Color is
graded in groupings designated by letters; D,E,F- Colorless G,H,I,J- Near Colorless.
Anything below J you start to see light brownish or yellow tints until those colors
become more saturated and you enter the spectrum of fancy colored diamonds.
Carat- Carat weight is the unit of measurement by which a diamond is calculated.
Usually the first question asked by anyone about the diamond they want to purchase
is: What shape and size diamond are you thinking about?. To put into scale the carat
weight of a diamond, a one carat is approximately .2 grams.
