synthetic ruby mounted with a central collet set circular diamond in an openwork ovoid bezel between spear head shoulders on a reeded shank, 14 carat Viennese gold mark for 1866-1922, 9 carat gold London assay mark size T The first synthetic rubies were attempted in 1837 by Marc Gaudin and later developed in 1877 by the French chemists Edmond Frémy and Charles Feil. It was not until 1904 that Frémy and Auguste Verneuil invented a furnace which could produce a 'boule' that commercial production became feasible. An artificial/synthetic stone has all the qualities that are desirable in a natural stone, except they are made in a laboratory. They have the same appearance, chemical composition and therefore physical characteristics of a natural stone. These include: their crystal structure, how they refract light (Refractive Index), colour dispersion, Specific Gravity and most importantly for the wearer, hardness. This ring is stamped with Austro-Hungarian fourteen carat gold marks used between 1866-1922, indicating that this Verneuil ruby is a historically interesting early product of the flame fusion technique pioneered by Frémy and Verneuil. At the time, whilst producing a marvellous colour, this stone would have arguably been as costly and difficult to create as a natural, mined example.
