Emerald and aquamarine have been known and cherished since Antiquity, but it is only in the last few centuries that science has realized that these two coveted gems are actually different varieties of the same mineral -- Beryl. Number 7 in the popular extraLapis English mineralogy monograph series, "Beryl: And Its Color Varieties" surveys the mineralogy and localities of this popular gemstone.
