A magnificent long necklace, double row, made of pebbles of amethysts,
nephrite jade balls and 18 carats yellow gold balls.
The clasp also in yellow gold.
Jade is the gem name for mineral composed of either or both of two
different minerals, Jadeite and Nephrite.Nephrite is a fine-grained,
calcium-rich, magnesium, iron, aluminous amphibole.Though neither
mineral is very hard (6-7), jade is one of the toughest gem minerals
known because of the intergrown nature of the individual crystals.
One of a kind piece.
