Blue Jade (Also Know As Dainite) (REF:BJ6)

Jade can refer to either of two different silicate minerals: nephrite (a silicate of calcium and magnesium in the amphilbole group of minerals), or jadeite (a silicate of sodium and aluminium in the pyroxene group of minerals).

Jade has been used in some cultures as jewellery and for ornaments and is mostly known for its green varieties, though it appears naturally in other colours as well.

Blue Jade also know Dianite (named for the late Diana, Princess of Wales) is a variety of Jadeite, a sodium aluminium silicate of the Jade family, which consists of either Nephrite jade family branch or Jadeite jade family branch.
