Specification

DESC:FIELD
The present disclosure relates to a jewellery item, more specifically enamelled jewellery.
DEFINITION
External Shape- An external shape is a graphical representation of an object's form or its external boundary, outline, or external surface.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
Precious metals such as gold used for making jewellery for ages, considering the fact that some metals such as gold are valuable, do not corrode and are sustainable. Intricate designs are created on the outer surface of jewellery such as gold jewellery to make it more beautiful, thereby adding to its appeal. One such process that adds to the beauty of the jewellery is the process of enamelling.
The conventional method of enamelling is done after the tooling of the jewellery item is done to make the final product. Once, the enamelling is done, no other process is performed on the item, thereby resulting in a lacklustre enamel that is comparatively unappealing.
There is therefore felt a need for a method for making a jewellery item that alleviates the aforementioned drawbacks.

OBJECTS
Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows:
An object of the present disclosure is to provide a simple method for making a jewellery item.
Another object of the present disclosure is to provide a method for making an attractive enamelled jewellery item.
Other objects and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure.
SUMMARY
The present disclosure envisages a method for manufacturing a jewellery item. The method comprises the following steps:
a. forming a blank;
b. shaping the blank, by a V-shaped endmill tool, to form the jewellery item of a desired configuration;
c. configuring a plurality of niches, by a niche-making tool, at a plurality of predefined locations on at least one operative surface of said formed jewellery item;
d. injecting enamel, by an enamelling tool, in the plurality of niches;
e. creating a lustrous gem effect, by a lustering tool, on the enamel;
f. defining an external shape of the formed jewellery item, by a CNC machine; and
g. polishing, by a polishing tool, the enamelled surface of the jewellery item.
In an embodiment, step (a) includes a sub-step of forming the blank from a material selected from the group consisting of gold, silver, steel, platinum and copper.
In another embodiment, step (c) includes a sub-step of configuring niches having a depth varying between 0.5 mm to 0.8mm.
In an embodiment, the enamel is of ceramic.
In an embodiment, the enamel is of glass.
In an embodiment, step (d) includes a pre-step of selecting enamel of a single colour.
In an embodiment, step (d) includes a pre-step of selecting enamel of different colours.
In an embodiment, step (d) includes a post-step of drying the enamel with UV radiations for a predetermined time period to facilitate drying of the enamel.
In an embodiment, the post-step of drying the enamel is performed for a time period varying between 10-15 minutes.

The present disclosure envisages a method (100) for manufacturing a jewellery item. The object of the method (100) is to enhance the aesthetic view of the jewellery item by providing an enamelled surface having a pearlescent lustre on the jewellery item. The present disclosure will now be described in detail with reference to Figure 1 through Figure 3.
Referring to Figure 1, the method (100) for manufacturing a jewellery item includes the following steps:
Step 101: Forming a blank
The method (100) includes forming a blank for a jewellery item (200) (shown in Figure 2) by a conventional blanking method.
In an embodiment, the blank has a desired configuration.
In another embodiment, this step includes the sub-step of forming said blank from a material selected from the group consisting of gold, silver, steel, platinum and copper.

Step 102: Shaping the blank
The blank is mounted on a computer numerical control (CNC) machine wherein, the blank is shaped to form a jewellery (200) of a desired configuration by a V-shaped endmill tool provided in the CNC machine.
Step 103: Configuring a plurality of niches
The niches are configured on at least one operative surface of the formed jewellery item by a niche-making tool. In an embodiment, the plurality of niches is configured at a plurality of predefined locations on the at least one operative surface of the formed jewellery item.
Step 104: Injecting enamel
Enamel (210) of a desired composition is filled in an enamelling tool. The enamelling tool is used to inject the enamel (210) in the plurality of niches (205) configured on predefined locations of the at least one operative surface of the formed jewellery item (200), as shown in Figure 3.
In an embodiment, the enamel (210) is of ceramic.
In an embodiment, the enamel (210) is of glass materials.
In an embodiment, this step includes a pre-step of selecting enamel of different colours.
In another embodiment, this step includes a pre-step of selecting enamel of different colours.
In an embodiment, the step includes a post-step of drying the enamel (210) with UV radiations for a predetermined time period.
In another embodiment, the step includes the post-step of drying the enamel (210) for a time period varying between 10-15 minutes, thereby providing an enamelled effect to the jewellery item (200).
Step 105: Creating a lustrous gem effect
The lustrous gem effect (104) on the enamel (210) is created with the help of a lustering tool. The lustering tool is a dome-shaped tool configyred to be mounted in the CNC machine. The resultant effect of this step is a pearlescent lustre of the enamel.
Step 106: Defining an external shape of the jewellery item
The external shape of the formed jewellery item (200) is defined by subjecting the jewellery item to the CNC machine. In an embodiment, the external shape of the jewellery item (200) can be of any desired geometrical shape including arcuate or a linear shape. Employing the CNC machines to create the designs, allows customization of the designs while adding to its aesthetic appeal and uniqueness.
Step 107: Polishing
The step of polishing includes polishing the formed jewellery item (200) by a polishing tool. More specifically, the enamelled surface of the jewellery item is polished. In an embodiment, the step of polishing is performed in the CNC machine wherein the polishing tool is mounted. In an embodiment, the step of polishing includes a sub-step of filling any imperfections or gaps formed on the surface of the jewellery item. Both filing and polishing further adds to the lustrous finish that highlights the beauty of the jewellery item.
In another embodiment, the step of polishing includes a sub-step of thoroughly cleaning the bangle to remove any residues or impurities, thus ensuring a flawless final product.
In an exemplary embodiment, the method of the present disclosure is used for making a bangle (200) of 22kt gold and circular configuration as shown in Figure 1 and Figure 2.
Figure 2 illustrates an isometric view of the jewellery (200), i.e., the bangle having niches (205) configured thereon, according to the method of Figure 1. The figure clearly shows the niches (205) filled with enamel (210) (shown in Figure 3) having a gem effect which is mainly a pearlescent lustre. The gem effect especially the pearl effect is mainly obtained in step 104 that is creating the gem effect. Further, the external shape of the jewellery item depends mainly on step 105 i.e., shaping the exterior of the jewellery item.
Figure 3 illustrates a cross-sectional view of the jewellery having enamel filled in the niches of Figure 2. The figure clearly shows the niches (205) filled with enamel (210) having a desired external shape.
