.... Secondary crystal phases with a decrease in Fe and Mg, yet increase in Na, suggest early crystallisation of aquamarine, with goshenite being late. With similar crystal chemistry to beryl of columnar habit from other localities worldwide, the tabular habit of Xuebaoding beryl seems to be unrelated...

... is an elegant presentation by twenty-two authors on colorful varieties of beryl (including the varieties aquamarine, red beryl, morganite, emerald, goshenite and heliodor, in addition to the cyclosilicate species foursome noted above. Packed into the first 104 pages are contributions (the titles of which...

... is heliodore; and the colorless variety is goshenite . Hematite Fe 2 O 3 ; (Fig. 13) : Named from the Greek word “haimetites”meaning “blood-like,” a reference to the colour of the powdered mineral. Specularite or specular hematite is a variety of hematite that exhibits a flaky or sparkling...

... with the polysynthetically twinned ‘ tough ’ diamonds from Australia, and for cutting these diamonds they demand higher wages! Section 2 is devoted to gemstones associated with pegmatites. Beryl group is dealt in Chapter 6. Different types of gem-beryls; emerald, aquamarine, heliodor, morganite and goshenite are found...

... B eryl (ideally Be 3 Al 2 Si 6 O 18 ) is a mineral with a remarkable set of gemmological varieties: goshenite (colourless to white), aquamarine (blue), emerald (green), heliodor (golden yellow), morganite (pink) and bixbyite (a rare red variety). Originally determined in 1926, the crystal...

... several meters in size, large phosphate nodules (up to 15 cm in diameter), löllingite with minor arsenopyrite, and nearly gem-quality beryl (aquamarine, morganite, and goshenite) crystals up to 30 cm in size are present. Quantitative chemical analyses were obtained from polished carbon-coated sections...

... crystals. It is also found as perfectly transparent and variously colored crystals of gemstone quality ( e.g ., goshenite , aquamarine , emerald , heliodor , morganite, and red beryl ). Bazzite, a scandium analogue of beryl, commonly deep to pale blue, was first described from the Baveno pegmatites...

... a rich source of great varieties of gemstones, including sapphire, peridot, apatite, amblygonite, aquamarine, goshenite, scapolite, feldspar (moon-stone, orthoclase, labradorite, microcline), pyroxene (diopside, enstatite, ferrosilite), hornblende (edenite, pargasite), andalusite, kyanite, fibrolite...

... ). The incorporation of elements such as Cr, V, Fe or Mn in the formula introduces colour, resulting in a variety of mineral names such as emerald (green), aquamarine (blue), heliodor (greenish yellow), morganite (pink) and bixbite (red). Goshenite is colourless, either due to the absence of chromophores...

..., goshenite, and morganite), but will be referred to as such minimally throughout this paper. Rather, classification based on crystal structure and chemical separation criteria will be favored. A further 33 beryl samples (see Supplementary Material 1 ) were used to test predictions made based...
