Diamond! Crystal! Emerald! Do you know the fancy cuts of these various gems?-Part-1

A gemstone has to go through many steps from being mined from the mine to being made into a piece of jewelry. Among these steps, the most important is undoubtedly cutting. Only after this step, the gem will be transformed from a rough  stone into a real gem. A good gem cutting craftsman will choose a cutting plan according to the characteristics of the gem and the condition of the original stone to make the gem bloom the most perfect brilliance.

The perfect diamond cut makes the diamond exude brilliance. With the advancement of technology, various experienced cutting masters divide the diamond into various fancy styles, including: eight hearts and eight arrows, nine hearts and one flower, and ten hearts and ten. Arrow etc

1. Hearts and Arrows

Hearts and Arrows is one of the best cuts at present. It uses the world's top Cupid cut. Looking down from the cut surface directly above the diamond, you can see eight arrows of the same size, brilliance and symmetry. Below, there are eight hearts that are perfectly symmetrical and full, giving the wedding ring a unique collection value.

However, there are good and bad hearts and arrows. Perfect hearts and arrows are indeed rare. The heart-shaped pattern is slightly asymmetrical, the arrow part is slightly skewed, the sizes of the eight hearts are inconsistent, and the arrows diverge at different angles. Hearts and arrows diamonds with bends or even obvious shadows that make the pattern missing are bad diamonds.

2， ten hearts and ten arrows

Ten hearts and ten arrows is a superb diamond cutting process, which is more excellent than the eight hearts and eight arrows cutting process. The diamond cut with this process can be observed under the professional turning mirror. Ten hearts and ten arrows can be observed from the top of the diamond. Ten neatly arranged arrows can be clearly seen from the top of the diamond, and ten neatly arranged hearts can be seen from the bottom. According to optical principles, the more cut faces of a diamond, the stronger the reflected light and the more shining light, which makes the diamond fire surpassing diamonds cut by other processes.

Its characteristics are:

1. There are many cutting surfaces. It has 71 facets, which is 14 more facets than the ordinary Hearts and Arrows cutting process. The size, angle and symmetry of each section have precise requirements, so that the light can be refracted and reflected multiple times in the diamond to achieve a stronger diamond fire, which is 1.2 stronger than the fire of the diamond cut by the Hearts and Arrows process. Times.

.

2. The cutting is difficult and the cutting time is long. On average, only one loose diamond with the optical phenomenon of ten hearts and ten arrows can be cut out of every 300 rough diamonds. It takes six times more time than the Hearts and Arrows craft.
