How To Buy A Diamond – Full Guide

1. Gemological certificate for the diamond

First, it is important to understand the significance of the gemological certificate – its main function is to provide an objective opinion on the diamond data you wish to purchase.

I will now refer to four types of certificates:

A. GIA an American certificate that all the diamonds experts and gemologists  work with, provides services only to Diamonds Exchange members  – the most severe level of strictness and therefore the most expensive, but remember if you buy GIA you buy peace of mind. Recommended
B. EGL A European certificate with a severity level of one rank less(usually) from GIA,  can be issued in Israel and also provides services to private customers. Very recommended
C. Other gemological institutes – In Israel, there are a number of other gemological institutes that issue external gemological certificates , their level of strictness or reliability can not be estimated. Not recommended
D. Store certificate – like Section C There is no way to estimate the level of reliability and strictness of the stores so there we cant realy know if what we buy is what we get. Not recommended

2. Natural stone or treated

There are completely natural stones that come from nature and on the other hand there are man-made stones in different types of technologies.  Any stone that is not natural is worth much less than natural stones.

Now I will refer to two types of diamonds:

A. Natural stone – a stone created by nature without any human intervention at any stage. Recommended
B. Treated stone –  a stone that has been changed or created by men intervention. Its ok to buy a treated stone as long as the price paid for it is fair  (usually a third of a natural diamond) .  Not recommended
* A major drawback in the purchase of treated stones is the change in the treatment  over the years because of contact with Chemicals, exposure to  heat, etc. – which can cause stains visible within the diamond.

3. Clarity Grade

The level of clarity is a significant component in the price & quality and shine of the stone you will purchase so it is important to understand each grade and thus choose the level that suits you.

Now I will refer to the five groups of cleanliness levels:

A. IF / FI – Perfectly clean without any defect identified by a microscope, is usually too expensive and there is no reason to justify the price for such an expensive diamond. Not recommended
B. VVS – Very high cleanliness with tiny defects that can be seen under a microscope with great effort, too expensive and there is no reason to justify the price. Not recommended
C. VS – High cleanliness with small imperfections that can be seen with effort with a gemologist lupa and easily with a microscope. Recommended
D. SI – Medium cleanliness with moderate defects that can be easily seen with Lupa and are not visible to the nacked eye, the ideal midpoint in terms of value per dollar. Very recommended
E. I – A low level of cleanliness with visible defects to the nacked eye, there is a consideration of budget and preference such as size and quality to justify this level of clarity. Not recommended

4. Color Grade

Unlike the clarity grade of the diamond which you are not able  to distinguish the clarity grade with the eye. The color of the diamond can be seen in almost all of its Grade except the theree first color grades. (DEF Collection).

I will now refer to four color groups:

A. D – F – “transparent” stones, completely white without any color – there is a consideration in the type of gold that you wish to set the stone , if white then the color will show, if yellow then it will be projected on the diamond and the high color will lose meaning. Recommended in white gold
B. G-H – Light color that is almost invisible but only looking with white color gemologists paper agianst a white fluorescent lamp you can see the light color. Very recommended
C. I-J –  Medium color shade that is visible, here enters the consideration in which jewel will the diamond be set on, on white gold the yellow colort will stand out. Recommended in yellow gold
D. K-Z – Strong and dominant color tone, here comes a personal taste decision to those  love diamonds with a strong yellow color. Not recommended

5. Cut Grade

An important component that does not receive the attancion it deserves, since the quality of diamond polishing work is critical because high quality work means “shine” and good light return from the diamond compared to a dull and lifeless diamond.

I will now refer to four cut groups:

A. Excellent – an ideal cut stone – this means a perfect return of light, usually traded among Merchants. Recommended
B. Very Good – Almost perfect cut stone – very good life-return, usually this level or less is sold in jewelry stores. Very recommended
C. Good – Level of cut that needs to be examined, ie what is the component that caused such a low grade in the cut grade. Not recommended
D. Fair – Very low level of cut which directly means low life & light returns , dull  and lifeless. Not recommended
