Nuummite, sometimes called the “Magicians Stone” or “Sorcerers Stone” is a gemstone formed from a mixture of two minerals, anthophyllite and gedrite. The name nuummite is derived from the Municipality of Nuuk, where the stone was discovered in 1982. Nuumite is believed to be the oldest mineral in existence having formed over 3 billion years ago. Metamoprhic influences on the rock give rise to the striking mixture of crystals which gives nuummite its unique appearance. The base color of Nuummite is charcoal grey to black, and its iridescent colors include red, orange, gold, silver, yellow, green, blue and violet.
Nuummite is generally easy to polish, even though, in certain qualities of stones with many parallel crystals, it can be difficult to avoid holes and cracks. Nuummite looks great when mounted in either gold and silver.
