Today I wire-wrapped the oldest rock I have ever made jewelry from (I think). Nuumite is found a remote local near Nuuk, Greenland. It was discovered in 1982 and is of a metamorphic origin. Web sources claim that the site is accessible only by boat.
I bought this cabochon at the Tucson Shows years ago because of the sellers claim that it was “one of the oldest stones on Earth”. This is a claim you hear commonly in various locations. I hear it all the time in the Keweenaw Peninsula. So how old are the “oldest rocks on earth”? Sources claim Nuumite is in excess of 3 BILLION years old. The Swedish guy that sold me the Nuumite claimed it was 3.6 BILLION years old.
When oriented correctly the Nuumite shows an"Inner Gold".
No glow is evident when the stone is turned.
Nuumite resembles Labradorite because it sports an oriented Labradorescence that some call Schiller Effect. I believe the stone to be a Hornblende and when oriented correctly it flashes a golden color on one axis. This is described as “inner gold”. When turned the stone is simply black and shows no “flash” until it is oriented correctly similar to Labradorite. I would say that the effect is more of iridescence, and not exactly like Labradorite. Nuumite is not as flashy as Labradorite.
Nuumite will probably not compete as a great gemstone, but it certainly has an interesting story and it does have a neat golden-brown glimmer. Also, many metaphysical properties are contributed to this rock. This piece of jewelry should appeal to the Geology Expert as well.
It is unfortunate you cannot see the “inner Gold” to its’ true effect.
In this pendant I used both gold and silver which complements both the black and golden tones in the rock. This is an unusual stone, an unusual cut, and an unusual wire-wrap. Everything about Nuumite is special.
