2. The Weight: The diamond is measured in carats.

The weight of a diamond is expressed in carats (1 carat equals 0.20 grams). Importantly, two diamonds of the same weight can have different sizes and prices. Keep in mind that the value per carat increases with the weight.

3. The Purity:

The less imperfections the purer the diamond The purity of a diamond is the characteristic that shows whether a jewel has imperfections or not, it may be fractures of the shape or traces of minerals. A diamond is considered pure from the time a specialized gemologist cannot find any defect with a 10x magnifier. To do this, in order to classify the diamond according to their level of purity, the following classification were introduced:

  • Flawless / Internally Flawless (Puro)
  • VVS1 o VVS2 (inclusions very, very small)
  • VS1 o VS2 (inclusions very, very small)
  • SI1 o SI2 o SI3 (small inclusions)
  • P1, P2 o P3 (Piqué)

Note that marks or imperfections in a diamond affect its value, but in many cases will not change its splendor and beauty.

4. The Color Diamonds: the more transparent, the more valuable.

The diamond is a stone that is characterized as shown in different colors (blue, green, pink, red, orange, etc..). Gemstone Specialists on the other hand claim , that pure diamonds are transparent and colorless. The more transparent it is better the quality. The color in the diamond  is due to the presence of impurities or defects. That’s why the color of a diamond is measured on a scale (GIA – Gemological Institute of America) going from the letter D (colorless) to Z (yellow or brown).
