Thomas W. Cresse INVENTOR NESS: I




Application filed March 31,

To all whom it may concern.-

Be it known that I, THOMAS WV. Gnnssn, a citizen of the United States, residing at Newark, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in Jewelry, of which the following is a specification.

My invention relates to an improvement in jewelry, and has especial reference to stone settings for various articles of jewelry,

. such as rings, pins, brooches and the like.

The object of the invention is to provide a setting the upper part of which comprises a cluster of stones and the lower part of which consists of a single stone, the two being so combined as to have the appearance of a single large stone or jewel.

It has been heretofore proposed to provide such a combination setting by attaching to the cluster .plate a number of platinum wires which are connected below the plate, these wires simulating the appearances of the facets of a diamond below the girdle thereof. A construction of this kind is relatively expensive because of the cost of the platinum and the tedious labor of attaching the wires and properly securing the "ends thereof below the cluster plate.

By means of my invention I am enabled to employ a cluster made up of chips or very small precious stones, and mount this cluster on the fiat table of a synthetic or semi-precious or imitation stone, or a precious stone of inferior quality if desired, and thus produce a setting having the appearance of a solid precious stone, but which may be made and sold at a considerably lower price than a precious stone.

The preferred form of my invention, illustratively embodied in a ring, is shown in the accompanying drawing, wherein Figure 1 is a side elevational view of a synthetic, semi-precious or imitation stone forming the support for the cluster;

Fig. 2 is a similar View of the cluster which constitutes the top of the setting;

Fig. 3 is a view of the setting mounted in a ring;

Fig. 1 is a vertical sectional view 011 the line 38 of Fig. 3 through the setting therein; and

Fig. 5 is a plan view of the cluster plate.

In constructing my improved setting I employ a stone 10 having a flat table 11 and faceted like a diamond. This stone may be Specification of Letters Patent.

made by cutting down a stone of usual form, with an elevated table, until the table is fiat as shown in Fig. 1.

To the fiat table 11 of the stone I attach the cluster shown in Figs. 2 and 5 which comprises the cluster plate 12 provided with the sockets 18 to receive the individual chips or small stones 14. The cluster plate and stone may be attached together by any suitable means known in the jewelers art, such as by pasting or by burnishing the edge of the cluster plate over the edge of the table of the stone 10. It is desirable that these two members shall be firmly united, and in Fig. 4 the edge 12 of the cluster plate is shown as burnished over the edge of the table 11 to provide a secure connection between the cluster and the stone 10. As thus combined the cluster andstone form a unitary setting ready for mounting.

In Fig. 3 the setting is shown as being mounted in a ring 15. The shank of the ring 15 is provided with the usual prongs 16 which lie against the stone 10 and have their upper ends turned in over the cluster so as to firmly retain the composite setting in position.

It is obvious that a setting such as above described may be made to so closely resemble a single brilliant or diamond as to be indistinguishable therefrom except by an expert or very close observer. The improved setting may be relatively cheaply manufactured and sold, and may be produced in a great variety of forms and with the use of a large assortment of stones.

hat I claim is A jewelry setting comprising a cluster formed of a cluster plate provided with sockets to receive individual stones at one side thereof, and provided with a surface fiat throughout its area at the other side thereof, and a faceted stone having a table flat throughout its area and huggingly flush and contacting with the flat surface of the cluster plate and of substantially the same size therewith, and means for securely connecting the cluster and faceted stone.

In testimony whereof I have affixed my signature in presence of two witnesses.
