Nephrite
Jade
Nephrite is a form of jade.
The term jade is used to describe two distinct
minerals-nephrite and jadeite. They may be similar in appearance,
but belong to different mineralogical groups. Nephrite jade belongs
to the amphibole group, and jadeite belongs to the pyroxene group.
Nephrite is a monoclinic amphibole that
ranges between the end members-tremolite (iron poor), and
ferroactinolite (iron rich). As more magnesium is substituted with
iron, darker shades occur. The color range we have found on the Salmon
River includes, white, lavender, light green, spinach green,
blue-green, olive green, green-grey, brown and black.
Custom orders and polished blanks are available.
Theoretically, pure jade, both nephrite and jadeite, should be
white. Chatoyant
tremolite is bright white shifting to translucent clear-gray. It is
suitable for jewelry and sculpture. Custom orders and polished
blanks are available.
Nephrite
is the toughest mineral, composed of interlocking, fibrous meshwork.
This characteristic has been used and appreciated by humans for
thousands of years. It was fashioned into ornaments, tools and
weapons by Neolithic people and has been used for religious tokens
by Aztec, Maya, and Maori cultures. Tribal groups in New Zealand
have used nephrite as a talisman of protection against attack or
illness. The Chinese have revered jade above all other gemstones and
it has a large place in Chinese history. Some of the oldest sites,
such as one in Siberia, extend people’s use of jade back beyond
5000 BC. In Northern Europe, Neolithic jade tools and weapons are
testimony to lasting utility and beauty.
