EXTRA LAPIS NO. 14: TOPAZ – PERFECT CLEAVAGE (Softback)

Published by Lapis in 2011, this Extra Lapis Series, No. 14: Topaz – Perfect Cleavage, provides one of the best presented accounts of this important gem mineral. Written by a select list of specialist academics, curators and collectors, this gloriously illustrated book not only describes in detail all of the classic Topaz-producing mineral deposits throughout history, but provides an unrivalled review on whether Topaz, as Topazius, was really know to ancient civilizations. Other important chapters describe David Brewster’s early 19th century experiments on inclusions within Topaz and what causes the colour of Topaz. Running to 100 pages, this exceptional publication is a remarkably detailed work which will be loved by collectors of gem species and those who are especially interested in the early history of mineral collecting in Brazil and Russia. Softback. New.
