Madagascan Eudialyte Freeform Palm Stone - 65mm, 84g
Locality - Madagascar Size – 65 x 37 x 23mm Weight – 84g
This freeform features pretty speckled plum purple eudialyte patterns in a highly-contrasting milky white microcline matrix. It has been nicely shaped to a smoothed, rounded, plump form and polished to a nice lustre, and despite a slight chip in one end (as seen in the 4th photo) it is still an attractive stone.
Eudialyte is an incredibly rare red to light brown gemstone typically found in massive form. It's rarity is due not only to its natural scarcity but also its alkaline form, which leaves it vulnerable to dissolving in strong acids; it is for this reason that it was named after the Greek 'eu dialytos', meaning 'well dissolved'. It is often found as grains embedded a variety of igneous rocks such as aegerine, albite, natrolite and nepheline. The south-western regions of Greenland produce much of this mineral, but minute amounts are also found in Canada, Norway, Arkansas and Madagascar.
