Jadeïte contre néphrite : Quelle est la différence ?

Nephrite: Ca2(Mg,Fe)5Si8O22(OH)2, amphibole group, hardness 6-6.5, from China (Hetian), Russia, Canada, New Zealand, with muted colors (creamy white, green). Jadeite is generally more valuable, especially imperial green. Both are beautiful and valuable; choice depends on personal preference, budget, and cultural significance.
