These are moldavites, which were probably broken in sediment. The parts of the moldavites were recovered. A moldavite of this type is usually broken down into two or three pieces, where to buy moldavite near me.
The process of “maturation” or “settling”, which is when the sediment settles, is where the most desintegration takes place. Moldavite bursts due to pressure from the upper layers. Over time, the refractive surfaces of moldavites become corroded and sculptations are made. The distance between pieces of moldavite is usually only a few milimeters. It is possible to join pieces that were separated by several meters.
Another way that moldavite puzzles can be made is by separating it from sediment and releasing tension. The moldavite could be broken down into smaller pieces. The refractive surfaces then become glossy.
Moldavites underwent a drastic change in their physical appearance on the Earth’s crust. It was caused both by chemical and mechanical influences. Breaking and cracking in moldavites were very important and led to the emergence of fragmental forms. It was caused by the impact of internal stress (in sediments) and occurred during the dropping and geological transport.
