Jewel made entirely by hand by the Italian craftsman Gianmarco Fontana. This 925 Silver ring depicting a human skull is part of the “Skulls” collection.
New ring dedicated to the human skull.
The human skull is undoubtedly the most complex bone structure in the human body, being made up of 22 even and unequal bones, often with a highly irregular shape and connected to each other with a certain variability. Most of these bones are flat, formed by two planks, a thicker outer one, and a less thick inner one, and a low-density spongy central layer, called cranial diploe. The thickness of the bones generally varies according to the muscle coverage, so those parts of the skull covered by a greater number of muscles or muscle mass will be thinner (and potentially more prone to fractures) than those that are relatively exposed. An example of the first type is the temporal bone, of the second the occipital bone.
The bones of the skull are interconnected by fibrous joints called sutures, which tend to close with aging, each within a more or less defined time range, although there are exceptions. They are essential, as they allow the bones of the skull to grow during development, growth that occurs from the inside out. The sutures of the skull are more and more complex as one proceeds from the inside to the outside and three types can be distinguished based on the forces acting on them. The first type consists of adjacent bones with regular margins, the second of blunt bones superimposed on each other, the third type of complex sutures formed by interdigitated bones. It is no coincidence that the former are widespread in the internal parts of the skull and the interdigitate are very common on its surface.
The ossification of the bones of the skull is often of the intermembranous type; even in adulthood these continue to be the site of hematopoiesis (even if they play a minority role compared to bone marrow and other bones). The bones of the skull base are formed by a process of endochondral ossification and their joints are synchondrosis, but there are also two synovial joints, the temporomandibular and the occipitoatlantoid.
