Estrela De Fura
Estrela de Fura is a 55.22-carat ruby, and in its rough shape, is considered amongst the largest gem quality rubies ever mined (101-carat). The stone is characterized by an extremely rare vivid red hue, fluorescence, and clarity. The gem was originally discovered in the Montepuez ruby mine in Mozambique, and its name is a Portuguese translation derived from Mozambique's official language. Estrela da Fura means "Star of Fura." History The ruby was discovered by Dubai-based FURA Gems in its mine in Mozambique on July 21, 2022. Before its unveiling and cutting, Daniel Nyfeler, managing director of Gübelin Gem Lab, stated: "the Estrela de Fura ruby is likely to yield an intense, saturated red colour once fully and properly faceted with adequate proportions, is relatively free of eye-visible inclusions. Considering its very large size, the vivid red colour, and clarity characteristics of this ruby give it an extraordinary potential to become one of the largest high-quality facete ...

Ruby
Ruby is a pinkish-red-to-blood-red-colored gemstone, a variety of the mineral corundum ( aluminium oxide). Ruby is one of the most popular traditional jewelry gems and is very durable. Other varieties of gem-quality corundum are called sapphires; given that the rest of the corundum species are called as such, rubies are sometimes referred to as "red sapphires". Ruby is one of the traditional cardinal gems, alongside amethyst, sapphire, emerald, and diamond. The word ''ruby'' comes from ''ruber'', Latin for red. The color of a ruby is due to the presence of chromium. Some gemstones that are popularly or historically called rubies, such as the Black Prince's Ruby in the British Imperial State Crown, are actually spinels. These were once known as "Balas rubies". The quality of a ruby is determined by its color, cut, and clarity, which, along with carat weight, affect its value. The brightest and most valuable shade of red, called blood-red or pigeon blood, commands a lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluorescence
Fluorescence is one of two kinds of photoluminescence, the emission of light by a substance that has absorbed light or other electromagnetic radiation. When exposed to ultraviolet radiation, many substances will glow (fluoresce) with colored visible light. The color of the light emitted depends on the chemical composition of the substance. Fluorescent materials generally cease to glow nearly immediately when the radiation source stops. This distinguishes them from the other type of light emission, phosphorescence. Phosphorescent materials continue to emit light for some time after the radiation stops. This difference in duration is a result of quantum spin effects. Fluorescence occurs when a photon from incoming radiation is absorbed by a molecule, exciting it to a higher energy level, followed by the emission of light as the molecule returns to a lower energy state. The emitted light may have a longer wavelength and, therefore, a lower photon energy than the absorbed radi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
