The value of diamond is determined by four main criteria. They are defined in the English literature as 4Cs: carat , clarity, color and cut. It's these parameters that influence the pricing, and the real value of the stone placed in the ring. The vast majority of customers that visit the jewelry shops do not have this kind of knowledge. Looking the rings with diamonds, the buyers of ten think that their price depends only on the size of stone. It is not that way! This situation is often used by the sellers. Most of jewelry shops in Poland offer rings with diamonds of medium (SI2) or low clarity (P1, P2,P3 - are low value diamonds with evident inclusions, external and internal errors visible from the side of stone crown).It does not happen by accident. The value of such diamonds is much lower, and their quality (gloss) also leaves much to be desired...
From the beginning of its activities, My Fable company has offered its customers a very high quality stones while maintaining competitive prices. We give you the opportunity to choose personally. It is the customer who decides at ours, whether he will purchase a ring in a version with a cheaper diamond, with lower quality (e.g. P1 or SI2 the color I or J) or betting on quality, will purchase the product with the highest class of diamond- (e.g. VVS with color F).
Colour is one of the most peculiar and at the same time the most important quality characteristics of diamonds. Estimation is made to only those colors which occur most commonly in diamonds, and which, from a commercial point of view, they are of utmost importance. These colors, often called typical, have shades from colorless (D - the purest white +) to yellow (Z - a sober 4) with varying degrees of color saturation; also there are bright color shades of brown or gray (light brown and light gray).

There are no perfectly clean diamonds. All naturally occurring diamonds contain contaminants that are characteristic of them. Purity of diamond is determined by the constituent elements of internal (inclusions) and external (blemishes), which also include structural defects.
LC/IF VVS1-VVS2 VS1-VS2 SI1-SI2 P1-P2-P3
There are 7 basic classes of clarity of diamonds:
LC - clean under the microscope;
VVS - very, very small inclusions, very difficult to notice at 10x magnification;
VS - very small inclusions, hardly noticeable at 10x magnification;
SI - small inclusions easily visible at 10x magnification;
P1 – inclusions hardly noticeable to the naked eye;
P2 – large / numerous inclusions visible to the naked eye;
P3 – large / very numerous inclusions visible to the naked eye.
The additionally used division of the clarity grade of VVS, VS and SI into subclasses [VVS1 and VVS2, VS1 and VS2 and SI1 and SI2 respectively] determines the size, position and number of inclusions.
In addition, there are also 2 classes of clarity of diamonds:
FL – clean flawless - no inclusions or blemishes;
IF – internally clean - no inclusions, showing only external signs (blemishes).
Cut – proportions and finish of grinding
Diamond owes its beauty - colors shimmering, sparkling rays - equally to the specific physical properties and proper treatment. In the case of brilliant grinding, the quality is determined on the basis of the following characteristics:
The quality of these characteristics determines the brilliance of diamond called fire and life of the diamond.
Widely used diamond shapes of diamond thin sections are: circular for whom is reserved the term 'brilliant' and 'fancy shapes', a term used to describe all other shapes besides round for example. princess, radiant, emerald, marquise, oval.
In international system mass (weight) of diamonds, as well as the mass of jewelry, is determined according to the metric system. The unit of measurement commonly used is called. metric carat (1 ct = 200 mg = 0.2 g). The weight of a diamond is determined with an accuracy of one hundredth of a carat (thousandths of a gram).
