East Java Purple Chalcedony

East Java Purple Chalcedony a rare find.There are 2 types that came from the same region of East Java, one is an outstanding  clear iridescent lavender color.  The other a beautiful purple chalcedony with black basalt matrix still attached which helps make your designs stand out.  The purple is a deep iridescent color and with its mirror shine it just glows. This material surfaced several years ago and the area they were working is now a rock quarry for roads in Java.  A new mine, now closed, shows different inclusions, including small copper crystals.
