Formed over 3.000.000.000 years ago. Nuumite is found in an area slightly north of Nuuk, Greenland – accessible only by boat. The area where Nuumite occurs is in the so-called ‘Isuakasia’ iron ore region, the origin of which dates back almost four billion years. Nuumite has been used rather widely for untold centuries as beads and ornamental stones. The locality is high in the mountains and requires lugging heavy mining equipment up to retrieve the best specimens. These areas produce some of the oldest stones found on earth, and Nuumite falls in this category. Geologically speaking, nuumite is of volcanic origin and was formed about 3 billion years ago. Subsequent influences on the rock (metamorphism) have given rise to the striking mixture of crystals which gives Nuumite its unique appearance. Rocks resembling nuumite are also found in a few minor occurrences in the USA, but it is only in the Greenland type that colouration is developed well enough for the stone to be suitable for gemstones.

At first glance, Nuumite appears similar to labradorite but upon closer examination the beauty of nuumite and its schiller effect is astonishing. Labradorite usually shows broad splotches of “flash” while the smaller mixture of elongated crystals in nuumite (often in sheaf-like groups) create a striking gemstone. In the transition between the individual crystals (and especially the thin ones), an optical effect is created causing a special “inner” golden brown glow. This effect is also called iridescence, and is especially distinct on polished surfaces. The result is that the crystals appear as bright lamellae, almost like flames in a fire. The colours vary somewhat between reddish, greenish, and bluish hues, sometimes even within the same lamella. Between the bright lamellae, the colour is dark brown to black.
