Kauri obtains its name from the Maoris and appears in various forms: kowrie, cowry, courie, coudie. It is gum of a light amber colour which has exuded from the Kauri pine (Dammara Australis) a species of Dammar growing in New Zealand. The gum is obtained by digging over spots where the trees once grew, and it is found sometimes in lumps the size of a football. Kauri gum is electric and much softer and less durable than amber. It has been suggested as a useful substitute for amber in throat troubles, asthma, hay fever and glandular swellings. It is under the celestial Taurus. KOLOPHONITE. (See GARNET.) KUNZITE. (See SPODUMENE.) KYANITE. Kyanite derives its name from the Greek KUANOS, blue. It is also written as Cyanite and, because of its unequal hardness, Disthene (twice strong). White specimens are termed RHOETIZITE. Chemically kyanite harmonizes with andalusite (q. v.) for both are silicates of aluminium, but as Dr. Smith writes, “points of difference show how large a share the molecular grouping has in determining the aspect of crystallized substances.” Usually kyanite is found in long, thin blade-like crystals and more rarely in short, full crystals. Its colours are light blue, blue and white, white, grey-green and, more rarely, black. Its hardness varies from 5 to a little over 7 in Mohs’ scale. When cut the blue variety resembles the light sapphire although it cannot display the same brilliancy. The stone is, however, very little employed in jewellery. The peculiarities of kyanite place it under the celestial Aquarius. LABRADORITE “_The beautiful opalised kind of felspar called Labrador stone._” PINKERTON. Also written Labrador, is an opalescent grey-blue felspar of extraordinary gleam, often reflecting green, yellow and red. It obtains its name from the place of its origin, as it was first found by Moravian missionaries in 1770 at St. Paul Island off the coast of Labrador. Specimens have also been found in stones of meteoric origin. The stone is effective and might with advantage be more extensively used in jewellery. Its hardness is the same as the opal. Labradorite is under the celestial Aquarius. LAPIS LAZULI “_The appearance of the Lord’s divine sphere in the spiritual Heavens._” SWEDENBORG.
