Brus determines the quality of the grinding and polishing of the diamond in the desired shape. These are mathematical rules of plots, angles, props, and symmetry, which ensure maximum quality of reflection of light and rainbow spectrum.
The most popular form of the brush of the round diamonds is the brilliant brus, and Marcel Tolkowsky developed it mathematically in 1919. The main feature of this brius is the maximum reflection of light, which the stone returns, which gives the appearance of fullness and brilliance.
Brus determines quality, not shape. Diamonds are abrasion into different shapes, from classic round, square shape (princess), pear, pear, rectangular ( emerald)… to various new modern forms. Different shapes emphasize the quality of the stone differently such as color, sheen, dispersion of colors.
The modern history of diamond search begins around 1860 in the Kimberley Region of South Africa, where the first major diamond mine appears. In 1953 the Gemological Institute of America developed a standard system of diamond evaluation, which is still used today.
Most of the diamonds are now being sanded in India, and the center of the trade-in these stones is the Belgian city of Antwerp. Modern times have also brought technology for artificial diamond production, but they are almost exclusively used for industrial purposes. Take a look here – 鑽石4c.
For easy cleaning of jewelry, you need a toothbrush and soap. The process is simple and fast and brings good results especially for jewelry with larger stones such as engagement and wedding rings and earrings.
Apply a little bit of mil (the one you currently have in the bathroom) to the brush and gently rub the product. Above all, clean it all around the stones, from all sides. Also from the back or from inside the rings, where when worn there is dirt, sweat, creams… Then rinse the ring with water and wipe with a gentle cloth or with toilet paper.
If the stones do not light up completely, repeat the procedure. The dirt can be persistent and stick slightly to the stones when worn longer. All you do is repeat the process.
This simple method usually works surprisingly well, as has already been said, especially in the case of jewelry with larger stones. Of course, it does not have the general effect of the wear of jewellery such as abrasions on gold parts. To this end, a visit to the jeweler is required, who will polish the jewelry and return his dazzling appearance.
