Some Really Practical Tips on How to Choose the Right Diamond – Precious Tips Art 3

Information about diamond classification (the 4 C`s) is available on almost every jewelry associated web site, but it has a common shortcoming. The information is rather technical than practical. In this article, I will focus on different aspects of the 4C`s which are not usually mentioned and try to give you information that will help you choose right and buy wise.

The 4 C`s mentioned above stand for: Carat, Color, Clarity and Cut

Carat- This is the weight, and not the size of the diamond. The two are very much connected but often customers do not realize that they are paying for the weight but are wearing the size and appearance. A diamond`s weight is measured in what is known as ‘carat’, which is a small unit of measurement equal to 0.2 grams. Carat is not a measure of a diamond`s size, since cutting a diamond to different proportions can affect its weight. Stones cut with poor proportions can ad a lot of weight and damage the appearance of a diamond. The usual reason for disproportional cut is to retain as much weight as possible (remember-you are paying for weight). Diamond like this must be sold with considerable discount. My personal opinion is to avoid such stones.

How do we know the stone is cut for weight? Look at the report that must come with the diamond report. If the cut is rated ideal, excellent or very good then there is no problem. Anything under this needs proper examination. Look at the paragraph “girdle “. This is the place where most weight is usually added. Sometime up to 20%.Girdle must be described 結婚對戒 thin or medium. The most important thing to remember when it comes to a diamond`s carat weight is that it is not the only factor that determines a diamond`s value. In other words, bigger does not necessarily mean better.

Color- Diamonds are found in nature in a wide range of colors, from completely colorless (the most desirable) to slightly yellow, to brown. So-called ‘fancy color diamonds” come in more intense colors, like yellow, blue, green and pink, but these are not graded on the same scale.

The best color for diamond is the lack of it. Color is an important quality but it is a bit overrated for none investment stones. Color is graded with the letters of the alphabet from D (ABC is skipped) being the whitest or more precise the most colorless to Z being rather yellowish. On the Gemological Institute of America`s grading scale, D-F are considered colorless, G-I near colorless and any grade J or below shows an increasingly yellowish tinge. Beyond the preference for a whiter stone, however, the color of a diamond does not affect its brightness or sparkle. The color of a diamond is best observed when it is placed table down on a piece of pure white paper and viewed through the side of the pavilion. The difference between two neighboring colors is completely undetectable for none specialist. Stones up to I and even J are perceived as white if there is no whiter stone next to them to compare. Color is a natural property of the diamond and although it greatly affects the price it should not be considered a shortcoming. Beyond the preference for a whiter stone, the color of a diamond does not affect its brightness or sparkle. The whiteness of the diamond is more important in case of pave set melee (smalls) where they must blend with the white metal around them. My advice is: for none investment diamonds go for colors G or H. Beautiful stones, great value for money.

Clarity is defining the existence (or lack of it) of natural inclusions or fractures in the diamond visible to a specialist by 10X magnification. Again, important for investment stones and not so for every-day-ring diamond. Clarity refers to the number, position and size of the inclusions that occur naturally inside diamonds. The fewer and less obvious the inclusions, the more valuable the diamond. The usual diamond grading information boards used widely by retailers to explain the 4C’s to customers, does not show the actual size and visibility of the different grade inclusions. They are, to say it mild, a bit misleading. The only way for a none specialist to see and assess the clarity is in the real diamond. Inclusions up to VS2 are not visible for none specialist under 10 x magnifications. Inclusions up to SI2 are not visible by naked eye. Inclusions up to SI2 and in most cases SI3 do not affect the overall appearance of the stone. My advice is: for none investment stones go for VS1 to SI2 or even SI3. Often the inclusion is a small dot or fracture on the periphery completely concealable by the setting.
