Buy a diamond It is not an easy thing. It is necessary to have certain knowledge to know if we are buying at a reasonable price or on the contrary the quality of the stone does not correspond to what we are going to pay. In these cases, more than ever, it is necessary to match the maximum Value and Price.
Once we have chosen the diamond that we like, we must look at 4 aspects that taken together will tell us a lot about our choice and the price to pay.
Diamonds: SIZE
It is the most important factor for the gloss of a stone This brightness will depend on the angles and how the light is reflected in the diamond, which will be different according to its proportions, which must be adequate to disperse the light.
Diamonds: WEIGHT
The measure used for the weight is the carat, which is the equivalent of one fifth of a gram (0,20 gr.). As these measures must be very accurate, for the value of each thousandth of a gram, 1 carat is equivalent to 100 points, so that if a diamond is 1,20 carats, it can be expressed as 1 carat and 20 points.
Diamonds: PURITY
A diamond will be more valuable when it is purer. That is, the more internal brands you have, the less pure it will be. These internal brands are called inclusions. It has been established that if an expert does not observe any defect in a diamond using a 10x lens, a diamond is rated as pure. The way to classify the purity of a stone is carried out by categories according to combinations of letters and numbers from greater purity to lesser: FL, IF, VVS1, VVS2, VS1, VS2, SI1, SI2, SI3, I1, I2, I3 . At first glance, only imperfections would be noticeable when compared to one of great purity, those listed as I1, I2, and I3. In other cases it is necessary to use a magnifying glass. It must be taken into account that the purity of a diamond can be modified although it is perceptible to an expert, so that this modification would be reflected in the certificate, devaluing its price by up to 80%.
Diamonds: COLOR
To classify diamonds according to their color, letters from D to Z are used, with D being a colorless diamond and as we ascend in the alphabet, it becomes more yellowish and of less value. There are also diamonds of various colors that because of their rarity also reach a high value in the market.
It is important to note that the market tends to value the quality of the size (its brightness) more and more, although the rest of the variables must also be valued.
When in doubt it is advisable to go to an expert, although we also recommend for greater security to request a geological certificate for diamonds of more than 50 points and buy diamonds with a color between D and I.
