Found in just one place on earth, tanzanite is a relatively recent discovery. It is said that the Masai tribesman Ali Juuyawatu found the first Tanzanite crystal in 1967 in the hills of Merelani in northern Tanzania. The name “tanzanite” is used for blue to bluish purple to bluish violet specimens of the mineral zoisite.
A magnificent discovery as this magical blue gemstone is known for its unique, beautiful and intense blue color. Tanzanite shows different colors depending on the viewing direction, from a bluish purple to a pure blue of violet blue.
Bonebakker used tanzanite in one of the rings from the Night & Day collection, due to its color changing nature. This collection, launched in 2015, is based on the ‘Keys of Amsterdam’, part of the rich heritage of the oldest jeweller of Amsterdam. These two keys, manufactured by Adrianus Bonebakker were given to Napoleon in 1811 as a symbolic access to the gates of the city of Amsterdam one for the day and another key for the night.
This historic heritage is revived in a contemporary jewelry collection with exclusive color-changing gemstones to symbolize the change from to day to night. Tanzanite is the perfect addition to this beautiful collection.
