Tiffany & Co,
The Guide to Diamonds. Everything you need to know
about the 4Cs. The 4Cs: cut, color,
clarity and carat weight are the standards that measure
the rarity and quality of a diamond. Cut is the most important
of the 4Cs. It’s all about how a diamond’s facets
or surfaces interact with light. When it comes to cut there are three things
to keep in mind. One, precision of cut, the dimension
and angles of a diamond. Two, symmetry, the alignment
and intersection of facets. Three, polish, the outside finish
of the diamond. More than anything else, these factors affect how light
travels in the diamond. If a diamond is cut poorly,
it will appear dull. If a diamond is cut well,
it will reflect and refract light for maximum brightness and sparkle. Cut is the only one of the 4Cs
determined by human hands, so expert craftsmanship is essential. At Tiffany, the world’s
most talented artisans, cut diamonds
to the highest standards. This precision makes
Tiffany engagement rings the most beautiful of all. Let’s talk about color and diamonds. In nature, most white diamonds
have a natural slight tint of yellow. Diamonds with a low color grade
can appear a bit yellow instead of the desired
brilliant white. The closer to colorless a diamond is,
the rarer and more valuable it is. Diamonds are given a color grade
from D, colorless, to Z, light yellow. At Tiffany, we only accept engagement diamonds
from D to I in the colorless and near colorless range
on the diamond color scale. Clarity is an assessment of
the imperfections in a diamond. A diamond with a low clarity grade
has multiple inclusions or blemishes which interrupts the refraction
and return of light and directly affects sparkle. That’s why Tiffany rejects any diamond
with noticeable imperfections to the unaided eye and only accepts
the best engagement diamonds. Carat is the weight of a diamond,
not the size. One carat equals 0.20 grams. By itself, carat weight
does not determine a diamond’s value. Two diamonds of the same carat weight
can appear to vary in size if one is cut deeper than the other. They can also vary in quality
due to clarity, color and cut. That’s why Tiffany diamonds
from the smallest to the largest stone
are always cut to maximize beauty.
