Each five-pound bag of potatoes costs the same at the
grocery store. But not every one-carat diamond fetches the same price at the
jewelry store. What gives?
What is a Carat?
In the jewelry trade, we use the carat to measure a
diamond’s weight. One carat equals 0.2 grams. Although a carat is a standard
weight, not every diamond weighing in at one carat costs the same.
Is Bigger Better?
One might argue that bigger is usually better. If you are in
search of the perfect diamond engagement ring, you might favor the larger
2-carat model versus the smaller 1-carat presentation. But is this really true?
The answer is no. While you undoubtedly expect to pay more for a two-carat
diamond ring, it may actually be comparable in cost to a one-carat jewel –
under the right circumstances. In the trade, we refer to those as cut, color,
and clarity, which further determine the cost of a diamond.
What are Cut, Color, and Clarity?
The diamond’s cut refers to its symmetry and proportions,
which directly affects its brilliance. Finding out about the color is sometimes
as easy as looking at the stone under natural light. A canary yellow piece is a
rarity and will fetch a higher price than a white diamond of equal weight. Even
a white diamond is not truly colorless. The color scale ranges from D (truly
colorless) to Z (too much color to be considered white). We previously
discussed clarity when talking about inclusions. In some stones, these are
considered of value-added appeal. In diamonds, they reduce the value. A
flawless stone will present with the FL rating while an I3 gem presents with
too many inclusions.
Diamond Examples
Case in point is this 1.0ct princess cut diamond ring with additional channel-set diamonds in a platinum setting. The focal stone weighs 1.0cts and
fetches an E grade, which means it is colorless. Its clarity rates as VS1,
which translates into a “very slightly included” mark, and notes that these are
too small to see for the naked eye.
In contrast, this 1.05cts princess-cut diamond engagement ring with channel-set diamonds in platinum presents with a G to H color rating. This
places it among the ranks of a near colorless stone. The clarity rating sits at
SI1, remarking on a slightly included display. You should be able to make them
out with a magnifying tool. Although slightly heavier than the first stone, the
second has lower ratings than the first, and therefore should be less
expensive.
