The semi-precious gemstones Agates are indeed a popular name in the world of jewelry. Agates are actually the colored variety of chalcedony. In turn, chalcedony is silicon dioxide (available in microscopic fibrous quartz crystals form). Moroccon Seam Agate is a pretty looking semi-precious Agate which often occurs in shades of orange, yellow, red and grey. The inclusion of seams on its surface and the fact that it is mostly mined from various locations around Morocco are the two chief reasons why this Agate is known as "Moroccon Seam Agate".
The question of how agates are formed has got an interesting answer. In fact, when the hollow pockets of host rock get filled in through layers and molecule-by-molecule, the agate is formed as concentric bands. Interestingly, the microcrystals in these rocks self organize! Agates are formed in the empty cavities. It is a fact that most of the gates of the world were formed in olden volcanic lava. The process of continents' formation forced the molten lava towards the surface of the earth. The lava contained various gases. The gases got relieved when rocks cooled down. This resulted in crack and cavities too. The varying lava-cooling rates also affected the types and formation of cracks. The Moroccon Seam Agate contains interesting seams and reflects parallel framed bands also. These bands actually fill the seams on Moroccon Seam Agate.
Every agate has a unique appearance. The agates are found in various hues and styles because these factors get affected due to a lot of things like the surrounding temperature, pressure and also the associated minerals of the host rock. You will be surprised to know that even if you cut any agate from the similar agate slab, the achieved agates will differ from one another.
