Agate is a gem from the quartz family, and dendrite agate is considered a part of the agate family. Tree agate stone or dendrite agate takes its name from the Greek word meaning tree-like.
This gem is one of the most abundant types of agates, so it is not difficult to find one of the most beautiful gemstones in the market. In ancient times, due to the importance of the properties of Shajar stone, the origin of this stone played an important role in all stages of the life of the ancestors, from trade to agriculture. In ancient Greece, the jewel of the tree was a symbol of the bride of the forest and the spirit of the tree, and for this reason, they buried it in their agricultural lands so that their crops would be high and of high quality.
How to form
The method of formation is that manganese dioxide Mno2 and silicon dioxide Sio2 are crystallized in close pHs, but the crystal crystallization and solidification of manganese dioxide is a little earlier than the silicon crystal network. But the question that arises is, how are the original Nagin Shajar roles created?
In answer to this question, we must say that when there is a silica crystal in the form of a jelly, manganese dioxide grows and crystallizes in a dendritic form, and after that the silica gel state cools down, and this time delay between crystallization There are two structures that cause the creation and stability of these shapes inside the stones. In the next step, the gem cutter, recognizing the path and the layer of the pattern, starts to cut the stone, and this is where the experience and taste of the jeweler artist is how to pull out the beautiful patterns from the heart of the stone and make this feature of the men's tree ring visible. .
