Igniter with safety unit, the safety unit comprises a push-button that is arranged at the backside of the gun body and partially protrudes out of the gun body, it can be pushed forward and return relative to the gun body; a elastic limit bar that is arranged at the side of the part of the ignition trigger that is towards the backside of the gun body, in natural condition, its end keeps against a barrier block which is integrated with the inner wall of the gun body; a button that is arranged in the push-button and protrudes out of the push-button, it can be pressed into the gun body and return. A protruding part arranged on the button's inner side protrudes towards a mid-portion of the gun body. In natural condition, the protruding part is towards the blank part, but when the push-button is in pushed up condition, the protruding part is near the end of the elastic limit bar and opposite to it.

A matrix is formed into a desired shape by pouring transparent liquid material into a mold. The material progresses from the liquid to the gelatinous state. Laser sculpting steps are performed when the material is still in a gelatinous condition to form small spots in the matrix. Because the material is non-solid gel when the laser beam applies its focused energy, there is no cracking or destruction. Intensity and duration of the laser pulse determine the size of the spots as does the timing in relation to the matrix material finally changing from gel to solid. Particular visual effects are produced at different degrees of solidity when sculpting. The liquid in the mold may be pressurized for removal of air bubbles after initial pouring of the matrix material and application of pressure after the laser sculpting controls the size of the spots in the finished product.

The invention relates to methods for marking valuable articles, mainly precious stones, in particular cut diamonds and can be used for article identification. The inventive method for marking valuable articles consists in forming a mark image visible in reflected light on a polished surface by modifying the ions of a surface area to be marked by means of the ion beam having the given ion energy and, while modifying, in converting the structure of the surface layer of a base in such a way as to change the optical characteristics of the modified areas in comparison to the optical characteristics of the untreated areas of the surface to be marked. The area to be marked is modified by a pulsed ion beam through a stencil mask by ion implantation of a modifier into a crystal lattice in the marked area of the base surface layer without destructing covalent bonds between the lattice atoms, i. e. without breaking the original shape of said layer. The optical characteristics of the modified area are changed by using, in the form of a modifier, the material, the ions of which change the integral refraction index of the base material when they are implanted into the crystal lattice in the form of impurity additives.
