NUUMMITE
Hardeness 5.5 - 6 Origin Greenland Treatment None
This is a rare mineral from Greenland that is relatively new to the gem world.
Amazing pattern of colors. The rarest colour is blue and there is a variety of silver and bronze colours.
We have sawn and rubbed the stones to exspose the colours .Nuummite gets darker as you polish it and finishes with a nice polish .
Known to be “The oldest mineral in existence”, Nuummite is a laminate, or sheet of compressed rock (presumably anthophyllite and gedrite) which is found in an area north of Nuuk, Southern Greenland. The area in which it is mined is accessible by boat only, in an iron-ore region which dates back over 4 billion years.
Nuummite is found in high, rugged, mountain terrain, making it very difficult to obtain. It is of volcanic origin and is believed to have formed about 3 billion years ago. Subsequent influences on the rock (metamorphism) have given rise to the striking mixture of crystals which gives Nuummite its unique appearance.

Pourquoi les utilisateurs se surenchérissent-ils ?
Lorsqu'une enchère est placée, il s'agit du montant maximum qu'une personne est prête à enchérir pour le produit. Notre système enchérira alors automatiquement au nom de l'enchérisseur, augmentant progressivement l'enchère jusqu'au maximum pour maintenir sa position de meilleur enchérisseur.
Lorsqu'une icône indiquant « Enchère automatique » apparaît, cela signifie que notre système place activement des enchères pour l'enchérisseur en fonction de son enchère maximale. Cela peut donner l'impression que les enchérisseurs se surenchérissent, mais c'est simplement le résultat de la mise à jour de l'enchère par le système pour refléter la limite maximale des enchérisseurs.
