A substantial Copal Resin specimen from Madagascar.
Sometimes referred to as "immature Amber", Copal resin is formed in the same way, but is geologically younger than true Amber, having been formed some tens of thousands of years ago.
This superb specimen is a long flow tube with a concave/convex cross-section, a result of the viscous, liquid resin having flowed over a small branch, twig or bark of its mother tree. Image 3 shows the layered flow structure of this gem.
Within the transparent host lie a range of insects and other organic detritus from its growth environment.
Visible by eye (and more so under magnification) are a small spider, a bettele and much more (see magnified images 4 and 5).
weight: 83.81 carats / 16.76 grams
shape: Natural elongated flow tube
dimensions: 82.14 x 24.05 x 15.15 mm
