What is the quality of a diamond determined by?
Diamond professionals use the grading system developed by GIA in the 1950s, which established the use of four important factors to describe and classify diamonds: Clarity, Color, Cut, and Carat Weight.
How do you determine diamond color and clarity?
The absence of color is what determines both its grade and value, as well as has a significant impact on its appearance. Diamond color grade is typically determined with the diamond face down and the culet facing up set against a pure white surface, following a grading scale of D (colorless) to Z (faint yellow).
How is diamond purity measured?
Diamonds and other gemstones are measured using a unit called metric carats. One carat is equal to 0.2 grams, which is the average weight of a raindrop. A carat is further split into 100 points and jewellers use the point system to weigh smaller diamonds.
Are all diamonds transparent?
Colored diamonds contain impurities or structural defects that cause the coloration, while pure or nearly pure diamonds are transparent and colorless. Most diamond impurities replace a carbon atom in the crystal lattice, known as a carbon flaw.
Should a diamond be transparent?
A diamond is transparent. However, this is just a measurement of how light passes through the stone. Whether a diamond is clean and without flaws is the diamond’s clarity grading, this is how a diamond looks, and if it has a cloudy or hazy look to it as well as blemishes such as spots, lines, and other potential flaws.
Which diamond is best for ring?
For engagement rings, we typically recommend round brilliant diamonds with a cut grade of very good, ideal, or super ideal (also known as hearts and arrows). Choosing a high cut grade maximizes the beauty of a diamond for a given carat weight.
How do you measure diamond clarity at home?
As a critical part of diamond grading, the accepted standard for determining diamond clarity is to examine the stone using a 10X microscope along with the trained naked eye. The level of visibility, the location, and the nature of inclusions (flaws) in a diamond determine the diamond clarity grade.
Which diamond clarity is best?
Flawless
What is the best diamond clarity? The best diamond clarity is Flawless (FL). To explain, a Flawless diamond features no internal or external blemishes. Similarly, the Internally Flawless (IF) grade means the diamond has no internal flaws, but might have external blemishes.
How do you check a diamond?
Water testing your diamond Get a glass full of water and simply drop your diamond into the glass. If the diamond is real, it will drop to the bottom of the glass due to the high density of the stone. If it’s a fake, it will float on the surface of the water.
What is the level of transparency of diamonds?
The transparency level of diamonds varies among stones and may be classified as transparent, opaque or translucent. Transparency can be measured and evaluated by individuals and professionals alike using professional grading scales and charts.
Why is a clear diamond transparent?
Because of heat conduction. Chemically, diamonds are made up only of carbon, but naturally occurring stones often contain traces of other substances, which were present when the diamond was formed. A typical clear diamond owes its transparency to its crystal structure, which allows light to pass through it.
How do you determine a diamond color grade?
GIA determines a diamond color grade by comparing the diamond to a set of masterstones. These are diamonds that have been carefully selected to meet specific criteria for carat weight, color, clarity and cut. Each masterstone in the set represents a letter grade.
How does color affect the value of a diamond?
Subtle differences in color can dramatically affect diamond value. Two diamonds of the same clarity, weight, and cut can differ in value based on color alone. Even the slightest hint of color can make a dramatic difference in value. This emerald cut diamond is colorless and is a D color grade.
