Kornerupine is a fascinating rare gem. It was originally described in 1887 and was named after Danish naturalist, A.N. Kornerup. The type discovery was of a massive opaque deposit, but soon after gem quality material was found. Since then Kornerupine has turned up inconsistently from many other world localities. No one locality has produced much of the material, and usually the deposits are quite small. This material from Tanzania is quite lovely. All Kornerupine is strongly pleochroic, and this material demonstrates both yellow and green when turned in the hand. This stone was cut parallel to the green color, but both the yellow and green reflect simultaneously. There are some very interesting blister like incisions through the stones. Kornerupine is rare, but unlike most rare stones it can be worn in jewelry. The hardness is 6.5 which is similar to Garnet. The stone glitters nicely in the hand and would make a lovely piece of jewelry or addition to a gem collection. This stone was faceted by Allyce and Brett Kosnar of Kosnar Gem Co., during April 2017. Enjoy!
