Eudialyte Decpomposes in Acid
The mineral eudialyte correctly pronounced you~die~a~lite was first described in 1819 in Greenland by German professor of chemistry Friedrich Stromeyer. The stone was named after two Greek words, 'eu' meaning 'well' and 'dialytos' meaning 'decomposable in reference to the fact that eudialyte decomposed particularly well in acids and in some cases dissolved completely.
The location where eudialyte is found helps with correct identification because this is a rare and complicated mineral that's known to have as many as forty six different chemical elements. Found in alkaline igneous rocks it's mined primarily in Mount Saint Hilaire in Canada and the Kola Peninsula in Russia but can also be found in Greenland, Norway and Arkansas in the USA.
Interestingly just the reddish coloured mineral that can be seen in the stone is eudialyte.
In crystal healing the mineral eudialyte is said to help with self love and aids giving love to others whilst helping one to learn about forgiveness. It facilitates extra sensory perception (ESP) and has been used to help optic nerve disorders. It replenishes energy levels in cases of over exertion, increases vitality, helps to cleanse the body and helps with the regeneration of damaged organs particularly the thyroid.
Eudialyte grades 5 to 5½ on Mohs scale of mineral hardness and when available tends to be used as a lapidary material. Fine specimens are sought after by mineral dealers and collectors.
