<p>[QUOTE=&quot;all_fakes, post: 150395, member: 55&quot;]I could be wrong, but I believe &quot;marbled jade&quot; would refer to a pattern in the jade, rather than being a different mineral.</p><p><i>&quot;Jade is a commercial term encompassing green, white, black or yellow-brown jadeite and nephrite. Jadeite is a rock that consists essentially of jadeite (sodium-rich, high-pressure pyroxene), whereas nephrite consists of prismatic to acicular amphiboles of the tremolite-actinolite series forming bundles that are randomly oriented and interlocked.&quot;</i></p><p>(From BC government site).</p><p>Nephrite jade is more common than jadeite; all the jade found in British Columbia is nephrite, and BC produces about 75% of the world&#039;s supply of nephrite.</p><p>The stone pictured looks to me like nephrite jade, quite similar to some pieces I&#039;ve seen from BC.[/QUOTE]</p><p><br /></p>
