ESSONITE. This
stone, which comes principally from Ceylon, passes under three names
according to its colour. The lightest of the three is of a pale
cinnamon colour, and is hence known as Cinnamon Stone. The next is a little darker, with a peculiar admixture of red and orange, and is known to jewellers as Jacinth. The last has a darker shade of bright red, orange and brown, giving rise to the peculiar hyacinthine tint, and it is therefore called in trade a Hyacinth. It
is a common error to confound these hyacinthine Garnets with Zircons
of similar colour, to which the names Jacinth and Hyacinth are also
applied.
