Attention! There are two very small chips (chipped) on the edges of the stone. Please look carefully at the photos and make sure that this option is suitable for you. Thank you.
The size is US 9 (diameter 18.8 millimeters). The weight is 4.15 grams. A durable and reliable silver ring with a high-quality laboratory ruby. In good condition. Remnants of gilding. Ruby has two small chips (chipped), glows in ultraviolet light like a natural one. 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.
