摘要： A jewelry chain having a pair of ends and a closure for releasably securing the ends together. The closure includes a male and a female component, each fixedly secured to a respective end of the chain. The male component includes a base member from which a circular disk of permanent magnetic material projects upward, a first tab and a first recess. The first tab projects outward from the base member perpendicular to the central axis adjacent a portion of the periphery of the disk, while the first recess projects outward from the base member perpendicular to the central axis adjacent a diametrically opposed portion of the disk. The female component includes a base member having a circular well of ferromagnetic material therein, a second tab, and a second recess. The second tab projects outward perpendicular to the central axis from the a portion of base member adjacent one portion of the periphery of the well while the second recess projects outward from the base member perpendicular to the central axis adjacent a diametrically opposed portion of the well. The disk of the male component is received within the well of the female component so that the components can be rotated with respect to each other to cause the first tab to enter the second recess while the second tab enters the first recess, thereby mechanically securing the components together.

摘要： Apparatus and methods for decorating a gemstone with colored indicia so that the indicia is readily visible from an exterior surface of the gemstone. The indicia is engraved on an predetermined exterior surface portion of the gemstone. The exterior surface on which the indicia is engraved may be the exterior surface from which it is visible, or another surface. The gemstone may be semi-precious, man-made, or precious, and can be faceted or cabochon. The indicia is engraved in the exterior surface by a laser beam. The laser beam is directed to the exterior surface, while the gemstone is held in a manner so that a significant portion of the laser beam is precluded from reflecting internally within the gemstone, thereby ensuring that the gemstone is not damaged by the laser beam. Once engraved a colored inlay, e.g., paint, is provided in the engraved recess to complete the decorative indicia. The decorative indicia is of a sufficient size for the message thereof is readily visible to the naked eye of a person when viewing it from the from predetermined exterior surface.

摘要： Apparatus and methods for engraving indicia on gemstones and the gemstones created thereby. The indicia may be either decorative indicia, readily visible to the naked eye, or identification indicia, invisible to the naked eye, and is engraved on or adjacent a predetermined exterior surface portion of the gemstone. The gemstone may be semi-precious, man-made, or precious and has another exterior surface portion for engagement by a portion of the apparatus. The apparatus basically comprises a support for supporting the gemstone and laser device for generating a laser beam and for directing it beam to the predetermined exterior surface of the gemstone to engrave the indicia therein. The support is constructed to engage the other exterior surface portion of the gemstone in such a manner that a significant portion of the laser beam is precluded by the support from reflecting internally within the gemstone, thereby ensuring that the gemstone is not damaged by the laser beam. The support can comprise either a fixture for engaging only the periphery of the gemstone or may comprise base having a recess therein for engaging the entire underside of the gemstone. In either case the support is formed of a laser-light transmissive material. A laser-light absorbing coating is preferably applied to the surface of the gemstone which is to be engraved by the laser beam.
摘要翻译： 用于在宝石和由此创建的宝石上雕刻标记的装置和方法。 标记可以是肉眼容易看到的装饰标记，或肉眼看不见的识别标记，并且刻在宝石的预定外表面部分上或附近。 宝石可以是半珍贵的，人造的或珍贵的，并且具有另一个外表面部分，用于通过设备的一部分进行接合。 该装置基本上包括支撑件，用于支撑用于产生激光束的宝石和激光装置，并将其引导到宝石的预定外表面以在其中雕刻标记。 该支撑件被构造为以这样的方式接合宝石的另一个外表面部分，使得激光束的大部分被支撑件排除在宝石内部的内部反射之中，从而确保宝石不被激光束损坏 。 支撑件可以包括用于仅接合宝石的周边的固定件，或者可以包括其中具有用于接合宝石的整个下侧的凹部的底座。 在任一情况下，支撑体由激光透射材料形成。 优选将激光吸收涂层施加到由激光束雕刻的宝石的表面上。
