Earrings Silver gold plated 925 assay value with tanzanite and cubic zirconia

About the main stone of the decoration Cubic cubic zirconia is an artificial analogue of a diamond. Initially, the stone was created as a material with certain optical properties for laser equipment and got its name from the place of its invention - the Lebedev Physical Institute of the Academy of Sciences (FIAN). Cubic zirconia is in no way inferior to a diamond in its appearance, it is perfectly clean, transparent and sparkles in the sun like a precious stone, allowing you to create real jewelry masterpieces. Cubic zirconia are presented in a wide range of colors and shades, so they are often used to imitate natural gems., Tanzanite - a mineral can be considered one of the youngest stones in history - it was discovered in 1967 at the foot of Mount Kilimanjaro. At first, tanzanite was mistaken for sapphire and did not attach any significance to it. Later, studies showed that the blue gem is a type of zoisite stone - a fairly well-known mineral that is not used in jewelry. It is a transparent, fragile and soft mineral. The stone has pleochroism - the ability to change shades depending on the viewing angle. This means that if you look at tanzanite from different sides, the colors will appear different. In daylight they appear blue, and indoors they change color to purple. Parameters of earrings: Height 20 mm, width 10 mm, working length of the pin 8 mm (classic). №1950143098
