This item is part of a historic collection of fossils and minerals which has recently been reviewed by leading geological expert Dr. Ronald Bonewitz. Literature Cf. Bonewitz, Dr. Ronald Louis Smithsonian Rock and Gem, (2008), p.290. Footnotes The specimen has at least 14 individual and parallel-twinned crystals; the largest crystal and several of the smaller crystals contain inclusions of the acicular mineral, identified as goethite. Aquamarine is one of the gemstone varities of the mineral beryl, a beryllium aluminium silicate. James Reynolds Gregory (1832-1899) was one of the principle London mineral and fossil dealers during the second half of the 19th century. The company he founded was one of the longest surviving geological suppliers in the world, second only to Kranz of Germany. In 1858 James Gregory established his business selling polished stones, minerals and fossils from premises in King William Street. A few years later he moved to premises in Golden Square, Soho. He won prize medals at exhibitions in Paris (1867), Sydney (1879) and London (1862 and 1883). He also formed a superb collection of meteorites, which was later sold by his sons to the Natural History Museum, London. On the death of his father in 1899 Albert Gregory took over the business, dealing from premises in Kensington, then 30 Old Church Street in Chelsea. He eventually sold the company in 1932 to Percy Bottley, and after his death in 1982 the premises were sold. The company was then acquired by Brian Lloyd who had started the Natural History sales at Sothebys before dealing from his own premises in Pall Mall. Gregory, Bottley & Lloyd, as it became known, traded from Ricket Street and later Seagrave Road in Fulham. In 2008 the business and all of the stock and Victorian cabinets were moved out of London to Walmer in Kent. On the eventual retirement of Brian and Mary Lloyd in 2014, with none of their family interested in taking over the business, the stock was sold and is now dispersed.
