4C’s of Diamonds
The cut of a diamond not only refers to the diamond’s shape, it also refers to how effectively the diamond returns light back to the viewer’s eye. A well-cut diamond will appear very brilliant and fiery, while a poorly cut diamond can appear dark and lifeless, regardless of its color and clarity.The cut of a diamond determines its brilliance. Put simply, the better a diamond is cut, the more sparkle it will have.
When shopping for a diamond, it is generally preferred to choose a stone with the least amount of color possible. Diamond color is graded on a scale from D-Z and is divided into five broad categories (colorless, near colorless, faint, very light and light). Diamonds within the colorless range(D-F) are the most rare and valuable of all those on the color scale.
It is important to select a diamond that does not have any inclusions that will affect the overall beauty and durability of the diamond. If you want to be 100% sure that your diamond will be completely clean of “eye-visible” inclusions, stick with diamonds graded “VS2” or higher. Shopping for SI quality diamonds can be very rewarding. It is also a good idea to balance the clarity grade of your diamond with the color. If you are looking at diamonds in the D-F color range, focus on clarity grades of VS2 or higher. Diamonds in the G-I color range combined with SI clarity are excellent values.
Carat is a term that refers to the weight of a diamond. For Polished Diamonds, it is a choice that depends on personal preference and budget. When looking at a diamond engagement ring, what is most visible is the size of the surface area on the top of the diamond. It is difficult to measure a diamond’s carat weight simply by looking at it. Although carat weight influences cost quite a bit, it is advisable to focus on diamond cut and diameter.

A completed certificate includes an analysis of the diamond’s dimensions, clarity, color, polish, symmetry, and other characteristics.Worls top certification authorities: GIA, IGI, HRD, GCAL, AGSL. Normally GIA diamonds are more expensive then IGI, and IGI a little more then HRD certified ones.
A diamond is comprised of the eight main components. They are Diameter, Table, Crown, Table Spread, Girdle, Pavilion, Depth, and Culet. Below is a brief description of each part of a diamond and its location.
- Diameter: The width of a polished stone, measured from edge to edge.
- Table: The largest polished facet located on the top of the diamond.
- Crown: The top part of a diamond extending from the table to the girdle. The crown is made up of bezel facets (crown mains), star facets, upper girdle facets (upper halves), and a table facet.
- Girdle: The very edge (widest edge) of the diamond where the crown and pavilion meet.
- Pavilion: The bottom part of a diamond extending from the girdle down to the culet.
- Depth: The total height of a diamond measured from the table to the culet.
- Culet: The small or pointed facet at the very bottom of the diamond.
