Extra information: Verneuil - Auguste Victor Louis Verneuil was a French chemist (1856-1913) He invented a type of blowpipe (chalumeau) with which he was the first to lab produce rubies. This process is also sometimes referred to as 'flame fusion'. His results were published in 1904. The apparatus is still used today (sometimes in banks of several hundred units) to make synthetic varieties of corundum and other synthetic gemstones. Other processes were developed but those are used less frequently, e.g. hydrothermal, flux fusion, and Czochralski. Padparadscha Sapphire - Natural Padparadscha is a delicate light to medium toned pink-orange to orange-pink hue corundum, originally found in Sri Lanka, but also found in deposits in Vietnam and parts of East Africa. Padparadscha sapphires are rare; the rarest of all is the totally natural variety, with no sign of artificial treatment. The name is derived from the Sanskrit "padma ranga" (padma = lotus; ranga = color), a color akin to the lotus flower (Nelumbo nucifera ‘Speciosa’). (from: Wikipedia)
