This is known as dendrite quartz. The plant like formation is an oxide of manganese that has formed in a hardly seen tenuous internal cleavage. These cleavages are due to internal tension inside the rock. It is not a clearly visible fissure. The manganese oxide has anciently penetrated in liquid state in the micro veins also known by the name of crystal foil. The bluish, opalized quartz color is due to the presence of tenuous fibers of actinolite and the yellow inclusion is known as cacoxenite. Cacoxenite is an oxide of iron. The rough crystal that originated this gemstone was found in the Brazilian State of Bahia and polished in São Paulo. A gemstone like this is able to attract more attention than an expensive diamond (brilliant) mainly when wearing an elegant woman in a sophisticated place.  It measures 24 x 20 x 9 millimeters and weights 36 carats (6.2 grams) </DIV></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/55D246C8-DB93-4356-A644-CE5BB22B7F29/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
