C1- Clarity

The study of diamonds and gemmology is quite extensive.4 C’s is a summary of all diamond characteristics that directly determines their monetary value. It is what consumers need to know in a nutshell.

Key Points

        • Clarity refers to diamond cleanliness in terms of the number, size, location, and type of impurities. It has the least impact on diamond beauty and attractiveness.
        • The majority of natural diamonds contain these impurities. They are mostly microscopic and require magnifying tools to be detected. The larger impurities can be seen with the naked eye. However, it is not easily detectable to an untrained eye.
        • The impurities are usually referred to as inclusions or blemishes.
        • Diamonds with smaller and sporadic inclusions receive the higher clarity grade.

The following are the terms used in the grading system from high to low and their meanings:

FL

Flawless, Internally Flawless (Fl - IF)Very rare and highly valued Complete absence of impurities in a diamond.

VS1-VS2

Very Small Inclusions (VS1-VS2):  Very high-quality grade small inclusions can be seen with a 10x magnifier with some effort. They are located mostly around the diamond table.

SI1 | Finest Gold Gallery

SI1

Small Inclusions (SI1)High-quality grade: Inclusions are easily detectable with a 10x magnifier. The number and location of the inclusions determine the SI level.

SI2 1 | Finest Gold Gallery

I2

Small Inclusions (SI2)High-quality grade: Inclusions can easily be detectable with a 10x magnifier. The number and location of the inclusions determine the I level.

SI3 | Finest Gold Gallery

I3

Included (I3): 
Good to lower quality grade Inclusion(s) can be seen with the naked eye. The number and size of the inclusions determine the I level

  • Key Points

 C2-Cut 

 

The cut is the most important characteristic that can affect diamond beauty and luster.

                • The cut grade rates the quality of the cut based on perfect proportions that could allow maximum light travel to the top of the diamond (table) resulting in the greatest sparkle.
          • Clarity refers to diamond cleanliness in terms of the number, size, location, and type of impurities. It has the least impact on diamond beauty and attractiveness.
        • The majority of natural diamonds contain these impurities. They are mostly microscopic and require magnifying tools to be detected. The larger impurities can be seen with the naked eye. However, it is not easily detectable to an untrained eye.
        • The impurities are usually referred to as inclusions or blemishes.
        • Diamonds with smaller and sporadic inclusions receive the higher clarity grade.
        • The following are the terms used in the grading system from high to low and their meanings:

Cut Grades

Ideal cut: Reflects all light entered the diamond. Highest luster.

Excellent Cut: Reflects nearly all light entered the diamond. High luster.

Very Good cut: Reflects nearly all light entered the diamond. High luster.

Note: it’s very difficult to distinguish between the ideal, excellent, and very good cut since they all produce high luster in the diamond. However, the price is different for each cut grade. To meet a certain budget, a very good cut can be a safe alternative.

Good Cut: Reflects the majority of light entered the diamond. Good luster. Cost-effective choice

Fair cut: Reflect enough light to the top of the diamond to produce sparkles and bring the diamond to life.

Poor cut: As a result of the too deep or too shallow cut, dark spots are noticeable in diamonds. Diamond with poor cut looks dull.

 
      •  

Natural diamonds come in a variety of colours such as Red, blue, Pink that are rare and therefore evaluated excessively high if the colour is not enhanced. However, the colour grade does not relate to various colours of diamond and is, in fact, a measure of the diamond degree of whiteness.

Key Points

        • The majority of natural diamonds are colourless and they range from whitest white to varying degrees of a yellowish tint.
        • The color scale is organized in alphabetical order starting from D that is assigned to the highest degree of whiteness and therefore highest value, while the S-Z range is indicative of brownish-yellow tone.
        • The middle range of G-I is descriptive of diamonds that are nearly colourless. While the beauty of white is still apparent, the price is reasonably reduced.

Colour is the second most important characteristic of diamond after the cut.

D- E- F:  COLOURLESS

G- H- I:   NEARLY COLORLESS

J- L :        FAINT YELLOW

M- O :      LIGHT YELLOW

P- R :       YELLOW

S- Z :       BROWN

C4: Carat

Carat is the unit measurement of diamond weight. The weight of a diamond has a direct impact on its value. Nonetheless, the valuation system is not a linear one.

The larger the diamond, the higher the value per carat weight

Key Points

        • For Example, A 0.99ct diamond (SI1/G Very Good Cut) may cost $5500/per carat while the same quality diamond that is 1.0ct  (0.01ct additional weight) could be worth $7100/ per carat.
        • Customers should also be cognizant of the fact that not all diamonds with the same carat weight have the same size and measurements.
        • The quality of the cut plays an important role in the size of the diamond.
        • Larger table size is preferable. It is the distance across the top portion of the diamond in mm.
