T 0 all whomz't may concern.
Be it known that I, EMMANUEL on Heart, a citizen of the French Republic, residing at Paris, Department of the Seine, in France, have invented certain new and useful Improvements in' the Method of Piercing, Threading, and Enameling Transparent Precious Stones, of which the following is a specification.
This invention has for its subject matter an improvement in the method employed for piercing, threading and enameling certain precious stones. For years in order toassemble certain precious stones in the form of collars, necklaces, pendant ear-rings, pendants, etc., it has been necessary to have recourse solely to the means employed for threading pearls which consists either in piercing the stone right through along its diameter or along a symmetrical axis and passing in the passage thus obtained a con: tinuous thread or wire, or in piercing the stone with a single hole of irregular form and of introducing thereinto a metallic wire, thread or the like. This method is quite unsatisfactory from the point of view of beauty when it is a question of transparency the effects of which are due to the reflection and to the refractions of luminous rays which are produced in the mass of the stone. The hole and the thread or wire which passes through the stone along its larger diameter are visible through the material and destroy to a great extent the harmony of these luminous eflects, thus rendering it almost impossible to obtain a tiara, necklace or collar of diamonds or other precious stones whilst retaining in the several stones their entire brilliancy and their sparkling effects.
The present invention overcomes these in conveniences by reason of the new method of piercing and threading and of enameling. The new method consists in forming one or more than one hole of as small a diameter as possible and as near the edge of the stone as possible. These passages are pierced perpendicular to the adjacent aligned stones. If. for example, it be a question of making a collar of spherical stones the piercing is effected for each stone as near as possible to the periphery of the stone and at two diametrically opposite points. Two adjacent stones are connected by passing a thread, wire or the equivalent through the nearest holes in the adjacent stones and this thread is knotted or tied or closed in any suitable manner.
The accompanying drawing shows diagrammatically and by way of. example constructional forms in accordance with the present invention.
Figure 1, drawn to an enlarged scale, shows partly in section the method of pierc ing a spherical stone which is to be used for the formation of a necklace.
Figure 2 shows the method of assembling several stones so as to form a necklace or collar.
Figure 3 shows another form of assembly in which the stones are suitably pierced.
Figure 4 shows the method of piercing a nonspherical stone on the assumption that {he stone is to be used for a collar or neckace.
As will be seen from 1, each stone 1 is provided with two holes 2 at opposite ends of the same diameter. The two holes 2 are parallel to each other and perpendicular to the diameter at the end of which they are formed. Into each of these holes is threaded a wire 3, the free ends of which serve to connect the stone to any other stone which is pierced in a similar manner.
The methods of assembly which may be employed are represented in Figure 2. In the left part of this figure, the two lengths of the thread or wire connecting adjacent stones are disposed in. an approximately parallel position. In the right hand part of the figure the two lengths of the thread or wire connecting adjacent stones are crossed as indicated at 3.
In Figure 3 an assembly of stones is shown comprising stones having different orientations. In this case the piercing is efi'ected according to the form of the article of jewelry to which the stones are to be applied. The two stones indicated at the upper part are provided with two holes which are neither parallel nor diametrically opposed. The stone which connects them is provided with three holes, etc. Obviously many other variations in the manner of connecting the stones are possible.
It will be seen from the drawings that the small holes 2 formed adjacent the periphery of the stones cannot have any effect on the brilliancy or sparkling efl'ect of the stone .d irection of assembly of the stones.
p daqaa by th sp c a cutt n t e Further, the mass of the stone is net traversed by a diametrical hole nor by a thread or wire capable of altering the brilliant effee-ts in question." q
The method is applicable to transparent ems f al k nds and QOl lJIS- It i an plicable with complete success as stated in the preamble to the present description to stones which are practically of spherical form. More generally it is applicable for the assembly of stones having approximately the form of regulargeometrical solids the axis of symmetry of which is disposed in the The holes are then pierced adjacent the ends of the axis of symmetry and perpendicular to this axis so that they may be assembled and threaded so as to form a collar, necklace or the like.
Figure 4 shows an example of a cut stone of somewhat Oli e form intended to be aligned on assembly ,along its major axis. In order to suitably position the stone it is pierced with two holes 2 at the ends ,of its major axis and perpendicular thereto. The method may ,then be used with less inter esting advantage for the assembly thereof.
It should be understood that the invention is not limited to the use of any material for the thread nor to any of the methods shown of assembly, the necklace shown having only been chosen and illustrated by way of example.
Claims:
1. An article of "jewelry including a plurality of smoothly cut stones, the bodies of each of which are provided with substantially opposite passageways arranged adjacent the enter edge of the body and parallel to each other and perpendicular of the diameter at which they are provided, and a plurality of links engaged with the adja cent passageways of the adjacent stones for connecting all of the stones together.
2. An article of jewelry as claimed in claim 1, wherein the linksare formed of crossed.
In testimony whereof, I hereunto afiix my signature.
