Description: The size is US 7 (diameter 17 millimeters). Weight: 3.90 grams.A durable and reliable silver ring with a high-quality Laboratory Ruby. In good condition. Remnants of gilding. Ruby has no damage, it glows in ultraviolet light like a natural one. Laboratory Ruby has all the properties of a natural stone: it is characterized by high hardness, strength and chemical resistance, it is resistant to scratching and wear. Production of the Soviet Socialist Union in the 1970s. The owner of this ring can confidently consider himself the owner of the "Purest Ruby" because only a gemologist using a microscope and studying the crystal lattice can distinguish a "natural ruby" from a "synthetic" one. Due to the fact that there were no natural deposits of precious Rubies (red stones and their shades) on the territory of the Soviet Union, Scientists of the USSR mastered the process of creating artificial corundums (Rubies) in laboratory conditions, completely identical to natural ones. According to the Verneuil method, an "artificial Ruby" was created from aluminum oxide under the influence of ultrahigh temperatures (2500 degrees Celsius = 4500 Fahrenheit), completely identical to natural in all parameters and properties, and much superior in purity. Artificially grown Ruby stones (red) and their shades are used in all jewelry of the Soviet Union of the USSR made of silver and gold.
