Brilliant cut : The modern brilliant cut was developed by Marcel Tolkowsky in 1919. It consists of 58 facets (or 57 if the culet is excluded). It is the most popular modern cut because it provides maximized light return through the top of the diamond.
Clarity : In order to establish the clarity of a diamond, the grader is using a 10x magnification. Diamond clarity scale ranges from FL (Flowless, no inclusion at all), IF (Internally Flawless, no internal inclusion), VVS1-VVS2 (Very Very Small inclusions), VS1-VS2 (Very Small inclusions), SI1-SI2-SI3 (Small Inclusions) and eventually I1-I2-I3 (Imperfect, for a diamond with inclusions visible even with the naked eye).
Tourmaline : Tourmaline is a group of ssemi-precious silicates. Crystals may be green at one end and pink at the other, or green on the outside and pink inside, therefore called "watermelon" Tourmaline. Tourmalines come from Sri Lanka.
