[[Imej:Jadestein.jpg|thumb|250px|Batu jed]]
Sebagai batu perhiasan, '''jed''' sebenarnya terdiri dari dua jenis batu yang terdiri daripada [[galian]] silikat yang berlainan. Jed [[Nephrite]] terdiri daripada galian [[actinolite]], [[amphibole]] yang kaya dengan kalsium dan magnesium (agregat yang juga membentuk satu bentuk [[asbestos]]). Batu yang dikenali sebagai [[jadeitite]] pula terdiri hampir sepenuhnya dari [[jadeite]], [[pyroxene]] yang kaya dengan natrium dan aluminium.

Perkataan 'jed' diambil dari bahasa Inggeris 'jade' yang diambil dari istilah Sepanyol ''piedra de ijada'' (pertama kali direkod pada 1565) atau 'batu pinggang ('loin stone'), kerana reputasi keberkesanan bagi merawat penyakit pinggang dan buah pinggang. Jed 'Nephrite' terhasil dari ''lapis nephriticus'', versi Latin istilah Spanyol ''piedra de ijada''.<ref>Easby, Elizabeth Kennedy. ''Pre-Columbian Jade from Costa Rica''. (1968).

Disebabkan keduanya digunakan oleh budaya Zaman Batu dan Gangsa untuk tujuan yang serupa, dan keduanya hampir sama keras dengan kuartz, tahan, cantik dan boleh dibentuk halus, keduanya tidak dapat dibezakan sehinggalah abad ke-19 oleh seorang ahli meneralogi Perancis.
<!--During the Stone Age of many cultures, jade was used for [[axe]] heads, [[knives]], and other [[weapon]]s. As metal-working technologies became available, jade's beauty made it valuable for ornaments and decorative objects. Jade has a [[Mohs scale of mineral hardness|Mohs hardness]] of between 6.5 and 7.0 [http://www.orionsgemz.com/Mohs.html], so it can be worked with quartz or garnet sand, and polished with bamboo or even ground jade.
Nephrite can be found in a creamy white form (known in China as "mutton fat" jade) as well as in a variety of green colours, whereas jadeitite shows more colour variations, including dazzling blue, lavender-mauve, pink and emerald-green colours. Of the two, jadeitite is rarer, documented in less than 12 places worldwide. Translucent emerald-green jadeitite is the most prized variety, both now and historically. As "quetzal" jade, bright green jadeitite from Guatemala was treasured by Mesoamerican cultures, and as "kingfisher" jade, vivid green rocks from Burma became the preferred stone of post-1800 Chinese imperial scholars and rulers. Burma ([[Myanmar]]) and [[Guatemala]] are the principal sources of modern gem jadeitite, and Canada of modern lapidary nephrite. Nephrite jade was used mostly in pre-1800 [[China]] as well as in [[New Zealand]], the Pacific Coast and Atlantic Coasts of North America, Neolithic Europe, and southeast Asia. In addition to Mesoamerica, jadeitite was used by Neolithic Japanese and European cultures.
Jade is the [[List of Canadian provincial and territorial symbols|official gemstone]] of [[British Columbia]], where it is found in large deposits in the [[Lillooet, British Columbia|Lillooet]] and [[Cassiar, British Columbia|Cassiar]] regions.

Batu jed banyak menghiasi barang kemas seperti cincin, rantai, gelang, serta alat perhiasan rumah. Lebih penting lagi, ia adalah simbol kemuliaan, maruah, dan ketinggian taraf. Tukang-tukang yang membuat perhiasan jed adalah antara orang yang terkaya di China. Corak yang biasanya menjadi pilihan ialah corak pic, itik mandarin, rusa, kelawar, serta ikan. Setiap corak ada maksud tersendiri. Sebab itulah harga jed mahal.
