Picking the Right Diamond: Be aware of Four C's

The gemstone is centered on the diamond. And because you need to wow her, that diamond will probably be an important investment. Being well-informed will be the only make diamond selection a painless process. To find the right diamond, it's important to have in mind the four C's: color, clarity, cut, and carat.

Color: Large in the diamond is definitely quantified. Along with is charted using letters to denote color purity. The top diamond color grade is D, as well as the scale continues right down to N or lower. Diamonds of your D grade are incredibly rare as they are colorless and brilliant. Diamonds below this grade are still beautiful, but will contain slight traces of color. These aren't easily noticed, but observe that diamonds graded K-N can have a small yellow tinge. In case you are thinking beyond the box, you will find diamonds in unusual colors. Blue and pink diamonds are rare and definitely create a statement.

Clarity: Clarity it's essentially how perfect the diamond is. Diamonds which can be flawless and without any internal imperfections (known as inclusions) and out marks of any sort can be extremely rare. Most diamonds incorporate some flaws, nevertheless they usually cannot be seen unless under 10x magnification. The number of diamond flaws are measured on the clarity grade scale. The very best clarity grade may be the rare Flawless grade. Diamonds that are graded below Flawless contain more inclusions. Diamonds with a grade of A little Included or Slightly Included provide a great value for your money. The imperfections can not be seen unless under magnification. You need to avoid diamonds with many inclusions since they can often be seen through the human eye alone and so they detract in the diamond's beauty.

Cut: Don't think about shapes when you hear diamond cut. The cut isn't of a square versus a round stone. Rather, the cut is about the way the proportion, dimensions, and elements of diamonds are cut.

You shouldn't have to memorize various areas of the diamond's cut, however you should be informed about a few things. A great cut diamond is the most suitable as the light will go into the stone and reflect back out, passing it on an increased shine. Diamonds that are cut either too shallowly or too deeply are not brilliant. Light will escape from the end with the diamond (shallow cut) or from the diamond's sides (deep cut). Experts rate cut using a naming convention such as Excellent, Very Good, and Good. Don't get a diamond that is below a Good grade. Most retailers won't sell t hem given that they will not reflect all the light.

Carat: Carat isn't a diamond's size, but alternatively, how light it is. A 200 milligram diamond is often a one carat stone. If you see a place system, don't be confused. Many retailers measure smaller diamonds with a point scale were 100 points equals one carat. Keep in mind that in nature, smaller diamonds will be more common than larger carats. So, if you are purchasing a large carat, anticipate spending quite a penny. Also, remember that the contour with the diamond matters. Diamond jewelry this is a princess cut might look bigger than a pear diamond - regardless of whether both are one carat.

With knowledge about the 4 C's, happen to be on the right path to becoming an authority when searching for that diamond!

Your Gem Stone Jewellery Certificate

From: solitaire engagement rings. One of the most unique features of your diamond jewelry is the individual certificate of identity called the gem stone grading certificate. Like people (and some pet animals), your stone's authenticity and individuality is officially confirmed with this certificate. 

This is actually a report given by an independent gemological laboratory. There are a number of gemological laboratories which hand out these certificates. 

However, only a few are respected by the whole diamond industry. The most well-known are the European Gemological Laboratories (EGL) and the Gemological Institute of America (GIA).

Individual stones

Each diamond is unique. This individual evaluation is strictly for the diamond's quality, not its value. 

The certificate maps out inclusions (imperfections), which are hand-drawn. This authenticates the diamond's unique identity, since no two stones are exactly alike.

Certificate details

The first information (alongside the issue date of the report) is the Stone ID. This is a unique number assigned to your diamond and registered in a global database.

Next listed is the diamond's cut and shape. If the shape is different from the standard round brilliant, it is called a fancy shape. 

The dimensions are listed down as "largest diameter - smallest diameter X depth" for the round shapes. The others are listed as "length X width X depth".

The weight is listed in carats, the standard unit of weights used for gemstones. (One carat is 200 milligrams.)

The grain lines reflect irregularities in the crystal structure. These are reported as colorless, white, colored or reflective.

The angles and measurements of the diamond that determine its optical properties are duly noted. Table size, crown angle and pavilion depth affect the stone's appearance.

The certificate indicates the thickness of the girdle (the outside edge of the stone) relative to the gem stone's size, and whether it is polished or faceted.  

The culet (the stone's bottom point) is listed either faceted or not. If faceted, it is noted relative to the size of the stone.

The grades of the diamond's finish and polish are noted and described including the symmetry. Color is graded, too, from D (colorless) all the way to Z (yellow).

Symmetry is the arrangement of the stone's facets (surfaces) and finished angles. Grading reports describe them accordingly, whether they are excellent, very good, good, fair or poor. 

The cut is listed as well as the quality of the stone's clarity. The clarity is the absence of inclusions (blemishes) and graded from "flawless" to "included" based on the size, nature, position and quantity of the inclusions.

The certificate also notes the pavilion depth (distance from the girdle to the culet) which affects brilliance. Deviations from the Tolkowsky ideal cut are also carefully documented.

Most diamonds "fluoresce" (showing whitish, yellowish, or bluish tint) when exposed to ultraviolet light. They are only stated in the report, not graded. 

Finally, there is a diagram on the certificate that approximates the shape and cut of the diamond. It has markings (in symbols) that include the type, nature, position, and approximate size of a clarity characteristic. 

Gem quality 

Coming from a leading gemological laboratory (the EGL mark appears under ultraviolet light), the certificate will ensure that your gem jewelry has the quality you paid for. Do your gems have certificates?

Please Answer This Maths Question?

In my test:

For diamonds of the same quality, the value, £V, and the weight, W milligrams, are connected by the formula:

V = kW²

For a particular quality of diamond V = 1000 and W = 50.

Calculate the value of k.

Please explain to me how you got your answer and make it easy to understand, because I have no idea. :S

Thanks. x

Plug in the given values for 'V' and 'W' into your equation.
Then solve for 'k'.

1000 = k(50)^2
k = 1000/2500
k = .4
