Ruby, along with sapphire, are varieties of corundum, a crystalline form of aluminum oxide. After absorbing short-wavelength light, there is a short interval of time when the crystal lattice of ruby is in an excited state before fluorescence occurs. A Web Experience brought to you by LEAFtv. [23] By 1910, Verneuil's laboratory had expanded into a 30 furnace production facility, with annual gemstone production having reached 1,000 kilograms (2,000 lb) in 1907. Ruby is also notable for producing a laser that is visible to the human eye, unlike many other solid-state lasers. Ruby Stone (Gemstone) is the stone of Sun which is a natural Aatmakaraka.

Different solutions and mixes have shown to be successful, however mostly lead-containing glass-powder is used at present. Sapphire, ruby, and pure corundum are α-alumina, the most stable form of Al2O3, in which 3 electrons leave each aluminium ion to join the regular octahedral group of six nearby O2− ions; in pure corundum this leaves all of the aluminium ions with a very stable configuration of no unpaired electrons or unfilled energy levels, and the crystal is perfectly colorless. All other hues of the gem species corundum are called sapphire. It is used both as centerpiece gemstone in pendants and rings, as well as a secondary stone to complement other gemstones such as Diamond s. Other varieties of gem-quality corundum are called sapphires. It stimulates circulation and amplifies energy and vitality to the whole system.

It is often called ruby in fuchsite or ruby fuchsite. Uses: As a gemstone, mineral specimens and as an abrasive. Orangy red through strongly purplish red. Most synthetic rubies originate from flame fusion, due to the low costs involved. For other uses, see, Artificial ruby under a normal light (top) and under a green laser light (bottom). Ruby is July's Birthstone. However, the finest red spinels can have values approaching that of an average ruby.[13]. The color of this mineral is red, and this color comes from the inclusion of chromium within the stone. [19] The process is done in four steps: If a color needs to be added, the glass powder can be "enhanced" with copper or other metal oxides as well as elements such as sodium, calcium, potassium etc. Rubies are also used in applications where high hardness is required such as at wear-exposed locations in modern mechanical clockworks, or as scanning probe tips in a coordinate measuring machine. If 694-nanometer photons pass through the crystal during that time, they can stimulate more fluorescent photons to be emitted in-phase with them, thus strengthening the intensity of that red light. These were once known as "Balas rubies". Ruby is also notable for producing a laser that is visible to the human eye, unlike many other solid-state lasers. Color ranges of the ruby gemstone are bright red, pinkish red, dark red, brownish red, purplish-red and pink. [21] When jewelry containing rubies is heated (for repairs) it should not be coated with boracic acid or any other substance, as this can etch the surface; it does not have to be "protected" like a diamond. Another treatment, which has become more frequent in recent years, is lead glass filling. [6][7] However, in the United States, a minimum color saturation must be met to be called a ruby; otherwise, the stone will be called a pink sapphire. The most common treatment is the application of heat. Emerald (green) and aquamarine (blue) are the mineral beryl.
