(bĕr`ĭl), mineral, a silicate of beryllium and aluminum, Be3Al2Si6O18, extremely hard, occurring in hexagonal crystals that may be of enormous size and are usually white, yellow, green, blue, or colorless. Beryl is commonly used as a gemstone. The refractive index is low, and the stones have little or no fire. The most valued variety of beryl is emeraldemerald,
the green variety of beryl, of which aquamarine is the blue variety. Chemically, it is a beryllium-aluminum silicate whose color is due to small quantities of chromium compounds.

. An aquamarineaquamarine
[Lat.,=seawater], transparent beryl with a blue or bluish-green color. Sources of the gems include Brazil, Siberia, the Union of Myanmar, Madagascar, and parts of the United States. Oriental aquamarine is a transparent crystalline corundum with a bluish tinge.

 is a blue to sea-green beryl; morganites are rose-red beryls. It is the principal raw material for the element beryllium and its compounds.

a mineral of the silicate class. Its chemical formula is Al2Be3(Si6O18), but because of the constant presence of alkalies (Na, Cs, Rb), Li, Mn, Fe2+, Fe3+, and Cr3+, and also water and gases (helium and argon), the composition of beryl is much more complicated. Various types of beryl—alkali-free, sodium, sodium-lithium, and lithium-cesium—are distinguished according to the alkali and lithium content. Beryl crystallizes in a hexagonal system, forming prismatic, acicular, or tabular crystals or complete granular masses. Beryl’s hardness on the mineralogical scale is 7.5, and its density is 2,650–2,800 kg/m3. The color of beryl is extremely varied. Depending upon the color, transparency, and impurities, the following types of beryl are distinguished: beryl proper—a green or yellowish-white cloudy crystal; aquamarine—transparent greenish-blue (the color of seawater) or dark blue crystals, colored with Fe2+ impurities; heliodor—yellow because of Fe2+ impurities; emerald—a transparent crystal of a deep grass-green color, colored by Cr3+; rosterite—colorless or pink owing to 5 percent or more Li1+ and Cs1+ impurities; and morganite—pink owing to Mn3+ impurities. Beryl forms in granitic pegmatites, greisens, skarns, and pneumatolytic-hydrothermal deposits of the metasomatic type. Beryl is one of the major minerals in beryl ore, from which beryllium is smelted. Transparent beautifully colored or clear crystals are cut to make high-quality precious stones.

Other members of the beryl family include aquamarine (blue to sea green), morganite (pale pink to deep rose and pinkish-orange), golden beryl or heliodor (golden yellow), and goshenite (colorless).
Science, with its rational, analytical approach, informs us that aquamarine is beryllium aluminum silicate, a member of the beryl family, and that its siblings are emerald, golden beryl, morganite, heliodor, and goshenite.

Richard Hannon saddles course-anddistance winner Heliodor, but fears him to be a "twilight horse, stuck between a stone and a hard place".
Miss Chamanda confirmed that form was no fluke when going one better on her next visit to Windsor, beating a handful of subsequent winners including Heliodor and Royal Ascot winner Flashmans Papers.
The rider went on to provide Hannon with his 75th juvenile winner of the year courtesy of Heliodor (6-1) in R.H.Hall/EBF Maiden Stakes.
Richard Hannon's Heliodor and Roly Boy could give him the most to do.
