You must have decided what type of diamond engagement ring you will buy, right? Now concentrate on what we say. Don’t buy a diamond just looking at the shape of it. Often buyers do this mistake while buying a diamond. They feel that the shapes of a diamond represent the cuts of a diamond. But this is absolutely a misapprehension. Cuts of a diamond definitely contribute to form the shape but the shape doesn’t represent the amount of brightness the diamond possess. We think, discussing in details will make this clear to you.
A cut of a diamond determines the brightness and brilliance of a diamond. It belongs to one of the four C’s of a diamond characteristics and gives the measure of proportions, symmetry and polish. Whereas, the shape determines the appearance of a diamond. Thus the beauty of diamond truly based on the diamond cut rather than diamond’s shape. While cutting a diamond, the cutter keeps in mind the diamond shape as well as its size. The cuts are formed with a symmetrical arrangement of facets, which as a result modify the shape and appearance of a diamond crystal. Round brilliant cut is the primitive cuts of a diamond.
in a diamond hold triangular shaped facets. Round brilliant cut diamond has a perfectly symmetrical arrangement of the cone shape which emits its intense brightness through the top. Mainly it contains 58 facets 33 on the crown and 25 on the pavilion. The perimeter of the diamond may be frosted, polished, smooth, or faceted. Mostly in recent brilliant cut diamonds, the girdle holds 32, 64, 80, or 96 facets which are excluded while counting the total facet. If the facet count is standard then the proportions crown height and crown angle, pavilion depth and pavilion angle, and the table size are not universally agreed upon.
Hearts and Arrows phenomenon of Round Brilliant cut
represents the visual effect with the perfect symmetrical shape and angles. Under a magnifying glass, if you look through the pavilion a complete and accurate pattern of 8 hearts are observed and 8 arrows are viewed when the dazzling stone is kept in table up position.
Slightly modifying the brilliant cuts in a diamond, and maintaining the basic proportions of its angles, passion cuts in a diamond are formed. Passion cuts are just an opposite of Hearts and Arrows phenomenon of Round Brilliant Cut. That is the arrows are eliminated when observed from the center of the diamond. In this type of cut, total number of facets is enhanced due to the splitting of 8 hearts of the pavilion. Thus the total facets increased from 57 to 81. This enhances the brilliance and mask inclusions.
Mixed cut is a mixture of brilliant cut and step cut features. The brilliance of the brilliant cut and the weight and dimensions of the step cut is combined to form this type of diamond. The First mixed cut diamond was Barion cut introduced in the year 1971. An original barion cut appears as an octagonal square or rectangular shape along with polished and faceted perimeter. It contains 62 total facets, that is 25 on the crown, 29 on the pavilion and 8 on the girdle. Radiant cut diamond also falls into this category. It is almost similar to the barion cut but the diamond has total 70 facets. The most popular shape of diamond formed by this type of cut is the Princess cut diamond. The shades of brightness emitting from the diamond is enclosed to the center and the colour diffuses to each of the corners. As the cutting techniques of this diamond are quite unique, the inclusions of the diamonds are rarely visible.
Rose cuts are acquired from the old techniques of diamond cuts. Rose cuts in the stone have a flat base which consists of only crown. The crown is constructed of triangular facets may be 12 or 24, which forms a point in an arrangement with sixfold rotational symmetry.
