The platinum cufflinks require regular cleaning

Often double crystal form; 3 formed by the mechanical action, under the influence of mechanical action, part of the crystal along a certain direction. The sliding of the surface network can form mechanical twins, such as calcite crystals along the (0112) surface mesh sliding under the mechanical action and the formation. Please do not force the cufflinks open to prevent deformation and fracture. The formation conditions of twins is very complex, the internal structure of the crystal twinning internal, but not every kind of mineral crystals. Can double-crystal, so from this perspective, the double-crystal may be an identification mark of the gemstone cufflinks mineral. Such as K-feldspar Stone card's twins, albite polysynthetic twin, chrysoberyl cufflinks contact with three crystal, spinel twins and so on. Crystal growth
The external conditions also play an important role in the formation of twins, ideal growing conditions are not conducive to the formation of double-crystal. So compared to them artificial gemstone cufflinks twins is much less than the natural gem cufflinks. You may want to ask the best professionals or attendants to clean the cufflinksfor you. Actual crystal morphology and crystal plane stripes. Prior to this, our discussion of the crystal morphology are ideal. The ideal crystal under ideal conditions, the crystal circumference. Around a growth center, strictly in accordance with its space lattice, in three-dimensional. Space evenly grown crystals (see Figure 1-1-20). The so-called ideal crystal in appearance, it should show as a regular geometric polyhedron with. Surface flat edge straight features; at the same time, in a crystal belonging to the same
The simplex crystal surface should be the same degree of development, with the same. But the actual crystal growth conditions are often very complex, a crystal growth process will always be different by the interference of external factors. It may be difficult to clean the cufflinks of a complex style.  From the microscopic point of view, the crystal is not strictly in accordance with the laws of space lattice, the formation of a uniform whole, so that the crystal can not be the ideal state of development. A real Single crystal, in fact, from the ideal uniform block these block is not strictly parallel to each other, thus forming a so-called "mosaic structure", "space" and "dislocation" structure defects. In addition, the constructed part of the particle
Replacement and the presence of inclusions can lead to crystal structural deformation (see Figure 1-1-21), coupled with the crystal after the formation, but also continue to be the stress and the late hydrothermal and other external factors, will increase the crystal non-ideal degree of. In this case, you should better drop the cufflinks to a special store to do a professional cleaning and maintenance every half year.  It can be said that all practical crystal internal structure are non-ideal, from the appearance deviated from their ideal crystal form, the only difference to the extent they deviate from the ideal situation is different. Common now in following the actual macroscopic crystal shape. Like, respectively, to illustrate to understand and grasp the ideal and the actual shape of the crystal, as well as the differences between them, the identification of crucial raw gemstone cufflinks.
In the actual crystal distorted crystal is extremely common. So-called distorted crystal deviate from their own ideal crystal, crystal growth in the non-ideal environment. Distorted crystal usually the same simplex crystal face development ranging from (ie not the same form large) part of the crystal surface can even be. The platinum cufflinks require regular cleaning. Can be missing, but the crystal surface angle and the corresponding crystal planes of the ideal crystal angle remained the same, this is the so-called "face angle law of conservation. For example, α-quartz crystal, which under ideal growth should form shown in Figure 1-1-22 (a) shows the crystal. But in fact it is often presented in Figure 1-1-22 (b) shown in several distorted crystal. It can be seen that the distorted crystal shape and size of the crystal planes of the same simplex, though not the same, but the same crystal face of the angle between the ideal crystal.
