1. Field of the Invention
The present invention relates, generally, to a gemstone bonding method, and more particularly, to a method of bonding different kinds of gemstones to provide gems having maximum beautiful appearance.
2. Description of the Related Art
In general, minerals or synthetic stones (hereinafter, referred to as ‘gemstones’), such as crystals, sapphires, emeralds, cubic zirconia, rubies, etc., are cut to manufacture jewelry, including necklaces, earrings, bracelets, accessories, etc. The cut gemstone has a plurality of facets by the degree of cutting, such that light leaving a gem is refracted or reflected to various angles, thereby exhibiting beautiful appearance. Further, such a gem may be applied to jewelry by holding it in place in an alloy bezel, or may be used alone.
However, since the jewelry using such mineral stones is expensive, it is composed mainly of one kind of gem, resulting in simplified function and beauty. Moreover, limitations are imposed on satisfying the demand of consumers requiring various kinds of gems.
Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, and an object of the present invention is to provide a method of bonding different kinds of gemstones to maximize the beautiful appearance of gems.
In order to accomplish the above object, the present invention provides a method of bonding different kinds of gemstones, comprising steps of: mixing a binder and a curing agent in liquid phases at a mixing ratio of 90˜110:40˜60 to obtain a mixture of binder and curing agent; applying the mixture of binder and curing agent onto bonding surfaces of different kinds of gemstones, and then drying/curing the applied mixture at 50˜180° C. for 2˜15 min to obtain a gemstone body composed of different kinds of gemstones bonded together; and cutting the gemstone body.
In the method of the present invention, the mixing ratio in the mixing step is preferably 100:50.
In addition, the drying/curing step is preferably conducted at 110° C.
Hereinafter, a detailed description will be given of the present invention with reference to the appended drawings.
As shown in
In the mixing step (S1), the liquid binder and curing agent are mixed together at the mixing ratio of 90˜110:40˜60, and preferably of 100:50.
The properties of the binder and curing agent used in the present invention are summarized in Table 1 below.
The components of binder and curing agent of the present invention are not limited to those shown in Table 1, and may vary with various environments.
In the drying/curing step (S2), the mixture of binder and curing agent mixed in the mixing step (S1) is applied onto the bonding surfaces of different kinds of gemstones, and then cured in a drying oven. The drying process is conducted at 50˜180° C. for 2˜15 min. As an experimental result of the present invention, although the drying process may be affected by the sizes of gemstones, it is preferably conducted at 110° C. The temperature and period of time required for the drying process may vary depending on the sizes of gemstones.
In the cutting step (S3), the gemstone body, in which the different kinds of gemstones are bonded by being cured in the drying/curing step (S2), is cut according to a variety of cutting processes, therefore obtaining a gem having maximum beautiful appearance.
The gemstone body composed of different kinds of gemstones bonded using the bonding method of the present invention is advantageous because of exhibiting excellent bonding strength and high heat resistance, endurable even at high cutting temperatures of 250° C. or more.
Turning now to
As previously described herein, the present invention provides a method of bonding different kinds of gemstones. According to the method of the present invention, the beautiful appearance of gems can be maximized, and as well the demand of consumers requiring various kinds of gems can be satisfied.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
