Compounds & Effects - Beryllium Chronic ulcers may result from skin contact. Berylliosis, a severe pneumonia-like disease, is caused by exposure to small amounts and can be fatal. Inhalation may cause bronchogenic cancer.
Beryllium Treatment A form of heat treatment for sapphire that adds the element beryllium to the heating process.
Beryllium (Be): Emerald (blue-green) Chromium (Cr): Emerald, Jade, Tourmaline (green); Alexandrite, Ruby, Spinel, Topaz Copper (Cu): Paraíba (greenish-blue), Turquoise (greenish-blue), Malachite (green) ...

beryllium aluminum oxide, Group of minerals including Alexandrite and Chrysoberyl cat's eye. Chrysoberyl Cat's Eye Greek meaning waving light.
It is Beryllium aluminum oxide, The chemical formula is BeAl2O4 . Colours Different shades of green and yellow like bluish green, brownish green, greenish yellow, yellowish brown etc.
Beryls are beryllium aluminium silicates rich in minerals. Pure beryl is colourless. However, on account of its structure, it is in a position to intercalate foreign elements such as iron, manganese, chrome or vanadium.
Chrysoberyl, a beryllium aluminum oxide, is not related to the mineral beryl as many might think by the name. Alexandrite and cat's eye are the most valuable varieties of the stone.
Beryl Beryl (beryllium aluminum cyclosilicate) is the name of a family of stones that includes Emerald, Bixbite, Aquamarine, Morganite, Goshenite, Golden Beryl, Heliodor, and Honey Yellow Beryl.
Aluminium (Al) and Beryllium (Be) oxide, Crystal Habit One-directional, narrow formation, splits into thin flat pieces.
Beryl - An ore of beryllium. CLEAR BERYL (also known as Goshenite) increases intellectual abilities, wisdom and the capacity to see things from all sides.
A more recent, controversial variant, involving "bulk diffusion", relies upon the diffusion of beryllium and/or other light elements at very high temperatures into natural colorless or pink sapphires, yielding yellow, ...
The newest method of deepening the natural color of a sapphire is bulk diffusion, whereby beryllium or a similar element is diffused into the surface of the gem, producing richer color.
Radical color change takes place within pink sapphires when they are heated with Beryllium gas.
The colors are produced by minor traces of elements in the - beryllium silicate - crystal lattice and when these are absent, the mineral will be colorless. The two most important gemstones in this group are emerald and aquamarine.
A trace of the element Beryllium is added to the stone during this treatment. If Titanium is added instead of Beryllium, during the process, near colorless stones can be treated to a good blue color.
Today a new method of artificially coloring the surface of paler rubies through the diffusion of beryllium, or a similar element, has made the red of ruby more affordable.
The chemical name of emerald is Beryllium aluminum silicate and the presence of chromium with it gives it its famous greenish hue. (Be3Al2(SiO3)6) is the chemical formula of emerald.
Beryls are hard minerals consisting of beryllium aluminum silicate.The most famous variety of beryl is emerald.
Emerald belongs to the beryl family, which is a crystal structure composed of aluminum and beryllium. Other beryl siblings are aquamarine (blue, blue-green) morganite (pink, peach), goshenite (white) and helidor (yellow, gold).
Due to its transparent nature, a natural gemstone called Beryllium Aluminum Silicate (Beryl), was often used in the divination process. Scottish Highlanders termed these objects "stones of power.
Chemical composition -- Beryllium aluminate. Optics -- R.I 1.74-1.77, biaxial positive or negative. Durability -- Hardness 8.5. Chrysoberyl is also exceptionally tough (resistant to breakage), so it produces some extremely durable gems.
Glucinum: (Also called "Beryllium") A rare silver-white metallic element resembling magnesium.
These liquids contain water, carbon dioxide, special elements (such as fluorine and beryllium) and volatiles (substances that are readily vaporized) that have escaped from the magma through fractures and fissures.
(Also called "Beryllium") A rare silver-white metallic element resembling magnesium. It is only found in nature combined with other elements, usually silica or alumina, in the minerals phenacite, chrysoberyl, beryl, euclase, and danalite.
A purple, lavender, white stone sometimes with patches of mauve, yellowish-brown and black is found in beryllium ore (Bertrandite) . This stone is known as opalite, ice cream opal, opalized fluorite and opal fluorite.
This process involves the use of diffusion to introduce colouring elements, such as beryllium, into the corundum to fill any possible voids in the crystal lattice structure.
The mineral or gemstone chrysoberyl is an aluminate of beryllium. The name is derived from the Greek for a gold-white spar. Read more in our Gemstones & Minerals Glossary Above is an example of Chrysoberyl. CHRYSOCOLLA ...

the name comes from the Greek "berylos", and the meaning has been lost. some varieties fluorescent, insoluble in acids, a very important economic mineral and the major source of beryllium. Gem info: ...
Alexandrite: Rare, color-changing gemstone which appears grass green in daylight and raspberry red in artificial light, some with "cat's-eye" effect. Available as synthetic. Composition: beryllium aluminum oxide; hardness: 8.5.
In beryl these parallel sheets are so strongly bonded together by beryllium and aluminum cations that they demonstrate only poor cleavage.
20%, titanium .90%, phosphorus .35%, magnesium .12%, strontium .06%, Beryllium .04%, copper .03%, lead .03%, zirconium .02%, chromium .02%, and zinc .02%; the remaining 0.16 percent is sulfur, chlorine, and water.
