Comprehensive Guidance About the Diamonds

About Diamonds

Today I would like to write about the king of gems, diamonds.

Glazed Diamonds Focuses more on accessories, especially Silver accessories, rather than Jewelry, so there are fewer opportunities to use diamonds Compared to brands that specialize in solid Jewelry. However, they still naturally use diamonds in Wedding Rings, for Example, and they sometimes use diamonds even in custom-made Gold or Silver items.

So, naturally, I thought I should write a little about diamonds.

What are the 4Cs?

First of all, the Term 4Cs is Essential when Talking about Diamonds.

The 4Cs are the acronym for the four words:

1. CARAT
2. COLOR
3. CLARITY
4. CUT

It's simple, but I'll explain each step.

CARAT

Carat is a unit of measurement for the weight of Precious Gemstones.

1 carat = 0.200 grams, and is expressed as "ct." (By the way, the "k" in gold is also a carat, but it is different from the one in Jewelry.)

It is usually measured to 1/1000 carat (0.001ct) and recorded on the certificate. Carat is a measure of weight, so it is also a rough guide to the size of a diamond. For diamonds of the same quality, the larger the carat, the more expensive it will be. (Of course, it's big.)

For reference, a rough estimate of the size is approximately 6.5mm for a 1ct diamond

(round brilliant cut).

COLOR

Color, as the name suggests, is the Color of the diamond.

The most Colorless diamonds are called "D Color," and as the Color (Normally Yellow) increases, they are graded from E to F to G to H to I to J... and finally to Z, making up a total of 23 grades.

As for the details of the grades, D to H are Colorless and are Called D (Exceptional White+), E (exceptional white), F (Rare White+), G (Rare White), and H (White), and the Color cannot be seen with the naked eye.

Below, I and J are called (slightly tinted white), K and L are called (tinted white), and M to Z are called (tinted Color).

Diamonds are pure lumps of carbon, but the more nitrogen impurities they contain, the more yellow they become. The evaluation of that yellowness is expressed in the grades D-Z above.

D is (almost) completely Colorless, and the further you go to Z, the stronger the yellowness and the lower the grade becomes. In other words, the price also becomes cheaper.

Some people may wonder why they don't use ABC. It is said that there is still a possibility that a rank of D or higher will be produced.

CLARTY

Clarity refers to the transparency of a diamond.

Diamonds may seem colorless and transparent at first glance, but in reality most diamonds contain inclusions. (An extremely small number of diamonds, called flawless, contain no inclusions.)

Clarity grades are determined by the size, position, color, and type of inclusions. So what are inclusions?

They are small crystals of garnet or other minerals that were present in the diamond when it crystallized. In other words, they are minerals other than diamond.

The inclusions (which are called mineral inclusions) = clarity grades are as follows:

・FL = Flawless

A stone that has no visible internal or external inclusions even when examined fewer than 10 x magnifications, it also has no scratches or cracks.

・IF = Internally Flawless:

This refers to stones that have no inclusions even under 10x magnification, but have scratches or cracks on the outside from polishing.

The above two grades are rarely available on the market and are considered to be quite rare.

・VVS1 (Very Very Slightly Included 1) Very Very Slightly Included 1:

A stone containing tiny inclusions that are difficult to see even under 10x magnification. This is usually considered the highest grade.

There is also VVS2 (Very Very Slightly Included 2) which is of the same rank. They are

almost the same, with VVS1 being just a little bit higher.

VS1 (Very Slightly Included 1):

A stone that contains inclusions that can only be found with 10x magnification by an experienced appraiser.

VS2 (Very Slightly Included 1):

A skilled appraiser may see inclusions that are not visible to the naked eye, but which may be visible to some extent (in some locations) only with 10x magnification.

・SI1 (Slightly Included 1) Slightly 1:

A stone that has some inclusions that are difficult for an experienced appraiser to see with the naked eye, but can only be seen with 10x magnification.

・SI2 (Slightly Included 1) Slightly 2:

A stone that has some inclusions that are just visible to the naked eye of an experienced appraiser, but are easily visible under 10x magnification.

I1, I2, I3:

Stones containing inclusions that are clearly visible to the naked eye.

The fewer the inclusions, the fewer the number and size, and stones ranked as I3 may have durability issues. Simply put, the fewer inclusions a gemstone has, the more expensive it is.

CUT

As the name suggests, it is the cut or shape of the stone. There are various cuts, such as round, brilliant, and others. It is an important factor in determining the shape of the diamond.

Here we will explain the typical round brilliant cut. A round brilliant cut is a cut that is round when viewed from above, with 33 facets (polished surfaces) on the crown (the upper half of the part (girdle) that protrudes the most when viewed from the side) and 25 on the pavilion (the lower half from the girdle), for a total of 58 facets. This cut is said to bring out the beauty of a diamond to the maximum.

So, I ended up writing quite a long post.

Diamonds are quite complex, and even just writing a simple explanation has become quite long.
