The icon "My Lord, Lord, have mercy on me"

Jewelry, like any expensive items, requires careful handling and certain care. Special attention should be paid to the appearance of jewelry in hot and humid climates. It is also necessary to protect jewelry from getting perfumes and cosmetics on them.

Platinum is one of the rarest and most precious metals on Earth. Its name comes from the Spanish platina, which means "little silver". Unlike gold or silver, platinum does not tarnish in the air, does not corrode in a humid environment and is not afraid of high temperatures. This gray-white metal has a unique chemical resistance, which makes it a symbol of purity and immutability.

In Orthodox iconography, the image of the Lord Jesus Christ occupies a central place. The icons of Christ are diverse: from ancient, dating back to the first centuries of Christianity, to later allegorical ones. But they all testify to one thing: about God, who became man for our salvation.

The diamond is often called the "king of gems", because its history dates back thousands of years. The first faceted diamonds appeared in the 15th century: in 1463, the first diamond was made, and a century later, during the Renaissance, classical diamond cutting was invented in Flanders, the prototype of which was natural crystals-octahedra. However, a diamond could only truly reveal its beauty and shine with all its facets in the 17th century, when diamond cutters learned how to split stones. The modern round diamond with 57 perfectly aligned facets owes its appearance to the mathematical calculations of Marcel Tolkowsky, who proposed in 1919 the parameters at which the optical properties of a diamond are revealed in the best way.
