So what are the 4 C's of diamonds? The first is the diamond cut.

The cut is the most important characteristic of a diamond, in terms of quality and value, and can greatly influence the physical and optical properties of a gemstone.1

The cutter of a natural diamond physically cuts the stone into it.different diamond shapes, paying special attention to the symmetry of the diamond and the dispersion of light. Essentially, the diamond cut is how appraisers judge the skill of the cutter and the beauty of the diamond. For appraisal, diamond appraisers or gemologists use a 10x magnifying glass to verify the cut of the diamond.

This grading determines the diamond's quality, cut grade, and price.

except knowhow to clean diamondsTo achieve that sumptuous sparkle, a superbly cut diamond can achieve optimal diffusion of light, sending brilliant sparkles all around. A bad cut, on the other hand, can accentuate the diamond's inclusions or flaws, reducing the diamond's value. When it comes to understanding cut, there are a few key terms that will help you when shopping for diamonds:

Round Brilliant -As the most common type of cut, the round brilliant has 58 polished surfaces (called facets). Each facet is designed to maximize the amount of light reflected by the natural diamonds into your own sparkling eyes.

Belt -Like the tight garment of yesteryear, the girdle affects the circumference. In relation to diamond cuts, the belt is the circumference of a diamond at its widest point. It is the thin perimeter of a diamond that separates the crown from the canopy below. A slightly thicker and more proportionate waist gives a higher score by default:

Extremely thin:Prone to chipping or breaking, jewelry must be handled with care.

Too skinny:Good proportion of precious stones; Jewelry care should be observed.

Fine, Medium:Ideal Gem Ratio

A little thick, thick:Excellent to ideal yolk ratio

very thick:Good proportion of precious stones.

Extremely thick:More depth can make the diamond gemstone look smaller

in this -The chop is the lowest point of the diamond, located at the foot of the pavilion. It is judged by its size and angle. A diamond with a small, pointed culet is one of the highest values. When grading chops, graders refer to the following standard grades:

Very big:Highly visible, it affects the appearance of the diamond gemstone.

Furthermore, there are four aspects of an ideal cut that affect the optical and physical properties of the diamond.2:

shine -No, brilliance is not just a measure of intelligence. In fact, brilliance refers to the amount of white light that reflects off a diamond and returns to the eye. Brilliance is one of the most important factors in evaluating the quality of a diamond. A poorly cut diamond can appear dull and dull compared to diamonds that reflect light enough.

Lustre- While brilliance refers to internal and external reflection, brilliance refers to the quality and quantity of light reflected exclusively from the diamond's surface. It is directly affected by the hardness and polish of the stone.

dispersion- Have you ever admired the iridescent reflections of the rainbow reflecting off the glass curtains? Dispersion is something like that. The dispersion of a diamond is the display of a rainbow-like spectrum of colors within it. It is often called "fire" and is an excellent indicator of how proportionate a diamond is.

shine- Essentially, it's the brilliance of a diamond when it comes to movement: the brighter, the brighter.

Understanding the technical aspects of diamond grading is important when trying to find the ideal diamond and price. But most importantly, you will also fall in love with the diamond!

If shimmer isn't your thing, don't be afraid to look for a softer stone.


The color of the diamond directly affects the price. A diamond in the rough comes in a spectrum of shades and color shades. The most desirable is the pure white or colorless diamond. Diamonds with this color grade are also the most expensive.

When grading a diamond's color, laboratories assess the extent to which diamonds deviate from "pure white." Optical and Physical Characteristics Stones are graded on a moving alphabetical scale, with 'D' being the most valuable diamond grade:

  • Colorless:D, E, F
  • almost colourless:G, H, I, J
  • Faint:k, l, m
  • Very easy:N, O, P, Q, R
  • Luz:S, T, U, V, W, X, Y, Z

However, some diamonds come in a vibrant variety of colors, from ruby ​​red to plum purple. These colored diamonds are aptly called "fancy".

While a white diamond is prized for its lack of color, elegant ones adorned with brilliant hues are prized for their depth of color. The more intense the color, the higher the value.


The price of a diamond can vary greatly depending on its quality. For example, a grade D diamond is exponentially more expensive than a grade E diamond.

G and H grade diamonds are highly prized stones that are still a good budget option. Grade I, J, and K stones are typically considered commercial grade diamonds and can be found at many diamond jewelers, including ours.jewelry store in san diego.

Ranked K through Z, Cape Diamonds are slightly yellow and boldly approachable. Lemon diamonds, those with deep yellow undertones, are graded W through Z and tend to be the cheapest.


As a diamond develops, microscopic impurities called inclusions become embedded in the diamond's surface, which can affect its brilliance. This is known as acloudy diamond.

The number of birthmarks determines the clarity of the diamond: the fewer blemishes, the more valuable the stone. To this end, the clarity characteristics of diamonds are classified on the following scale:

  • Perfect:Florida
  • Very very light included:VVS1, VVS2
  • Very easily included:VS1, VS2
  • Easily included:SI1, SI2, SI3
  • Imperfect:I1, I2, I3

Diamonds that are flawless both externally and internally have been determined by the American Gem Society to be incredibly rare and particularly expensive. However, most of the time, the naked eye cannot see the inclusions in a diamond unless the stone is enlarged. In this case, SI quality diamonds are the most cost-effective and seemingly flawless option.

In fact, a freckled diamond could be just what you've been looking for, especially if you or a loved one value subtle, natural uniqueness.


Although a diamond's carat is not related to what vegetable you eat, it represents the world standard for diamond weight and size. The size largely depends on the shape or cut of the diamond.

In fact, the term "carat" refers to the carob seeds that were used in ancient times to measure the weight of a stone with a balanced scale. To put it in perspective, a carat is 200 milligrams and an ounce is 142 carats.

A carat is also illustrated using a point scale: one carat corresponds to 100 points.

The larger the stone, the higher the carat. The higher the carat, the higher the value.

Pretty easy, right?

While larger diamonds are generally considered more valuable, the carat rating of a larger diamond is not the only determinant of its price value. As you know, testers also consider cut, color, and clarity.

(Video) A guide to diamond grading. How do the 4c's actually affect a diamonds appearance?

A diamond cutter can really affect the carat weight of the diamond with its cut. Precision is key, as diamonds are typically weighed to within 0.01 carats.4


The price of a gem increases exponentially as the carat increases. In other words, there are large price differences between each carat weight category.

For example, a 0.75 carat diamond costs around $3,000, while a 1.00 carat diamond costs around $10,000. That is a noticeable difference.


Let's review again: What are the 4 C's? From most influential to least influential, it's all about cut, color, clarity, and carat. While these factors contribute to the unique characteristics of each diamond, it is important to remember to look at a diamond as a whole, especially when it is on the market.

Finally, your unique preference counts too!
