Manufacture Process

The world’s finest jewelry is handmade, one piece at a time. To be considered “Handmade Jewelry” it item must be fabricated from raw metal by a jewelry artisan, using only tools that are controlled by hand. The lost art of jewelry making fine handmade jewelry requires highly skilled labor to manually control tools and to transform precious metals and gemstones into works of art. It is for this reason that jewelry connoisseurs everywhere know handmade jewelry is the benchmark for craftsmanship in fine jewelry. However if you have high quantity of jewelry then you must go for machine made process.

STEP 1 – DESIGNING

In order to produce a unique piece, the very initial step is to create a design. This is the point from where the magic begins. It is a stage wherein the designer develops an idea for the design, evaluates the idea and translates it into reality.

STEP 2 – Buying stones and silver

First of all we buy the right set of silver. We have only stering silver. Sterling silver is also called .925 silver or .925 sterling silver. The .925 comes from the fact that sterling silver is an alloy mixed with other metals. .925, or 92.5%, is the minimum proportion of pure silver that must be included in the blend. The alloy is created to harden natural silver to make it durable and less prone to tarnish. Sterling silver for our art projects, jewelry making and crafts comes in wire, tubing, and sheets. Before silver is deposit in the bank first silver must be mined.

When we are buying our stone from around the world, we always ensure we gain the best and widest range of materials available. Everything they offer us is the best in the industry… Isn’t this what you want to hear? Literally everything is possible. Quality transcends throughout these companies whether it be their work samples, production facilities, showrooms or stone stock. These are stone companies investing in professional equipment and high quality materials. These are “stone” companies which we enjoy a long standing and committed working relationship with. We have decided to work with the best in the industry, and it gives satisfaction not only to us, but to our clients as well.

STEP 3 – CAD

CAD software is used to increase the productivity of the designer, improve the quality and dimensional accuracy of design, and to create a database for manufacturing. Once a design is conceptualized in the mind of the jewellery designer, it is drawn on paper and then into the system. This process of constructing a design into the system is facilitated through Computer Aided Designing technology.

STEP 4 – RAPID PROTOTYPE

Once the CAD design file is ready, it is transferred on 3D Rapid Prototype system. This system works on the principle of Direct Light Projection Technology. The resin model is created using 3D Rapid Prototyping system (RPT) which is fully functional.

Step 5 – MODEL MAKING

Resin output from CAM is then converted into silver model by using casting process. The silver model is a master design that is copied to make many similar pieces of jewellery.The silver model is used to create the rubber Mold from which all subsequent pieces are made.

 Step 6 – RUBBER MOULD

Mould making is an integral part of the production process. It helps in creating multiple pieces of jewellery of the same design. These designs remain protected and embedded in the mould forever and it is possible to create replicas of the same in future. There are different types of materials used for mould making like natural rubber, silicone and metal. The method used for mould making is called “Vulcanizing”.

 

 

Step 7 – WAXING / WAX TREE

This step involves the production of wax pieces from the rubber moulds made from the silver master. The rubber mould is placed on the commercial wax injector machine. Molten wax is pressure injected into the mould cavity to create wax models for casting.

The process of soldering the wax pieces on a wax stem is called “treeing”. A sprue is attached to each piece which in turn is attached with the stem. The sprue makes an angle of approximately 45 degree with the stem. The tree is such that the heavier items are at the bottom of the tree and the lighter ones are at the top.

Step 8 – CASTING

Casting is a very complex process and requires utmost skilled and experienced casters for the desired final product. The wax tree is placed in steel flask which is then occupied with a slurry of chemical powder which solidify in an hour. The flask is than heated in an electric furnace which melts the wax leaving behind a cavity of tree. Molten metal is then poured into the flasks, allowed to cool, then demolished to reveal the Jewellery in casting form..

Step 9 – GRINDING

Once the raw casting is clipped off from the casting tree, it has a tiny nub leftover at a place where the gold piece was attached to the sprue. The polisher grinds off this nub using the motorized grinding machine, which acts as an abrasive to smooth the surface of the silver piece/jewellery. A final polishing is then done by holding the piece against a spinning&grinding wheel to achieve a smooth surface.

Step 10 – FILING / ASSEMBLY

Filing is a technique that helps in removing excess metal or solder from a piece that is being worked on. It is a process wherein the casting layer is removed by using different tools like files and burrs. It gives a smooth finish to the piece. Assembly is the process where two or more component of the same design is joint with the help of solder or laser technique

Step 11 – POLISHING

Polishing offers a neat finish and enhances the value of a piece. Polishing involves three steps, tumbling, pre polishing, and ultra-cleaning. Jewellery pieces with diamonds require pre polishing before the diamond is set. This is because once the diamonds are set the area below the diamond portion cannot be polished and may affect the shine of the diamond.

Step 12 – STONE SETTING

Stone setting is the art of securely setting or attaching gemstone in the jewelry. Different types of setting are used to create varied designs; sometimes even combination of two setting is also used to make a piece look more appealing. The different types of setting are prong, plate prong, pave, pressure, bezel, bead, flush, fishtail, invisible, miracle plate and channel.

Step 13 – POLISHING

This is the final polish of the piece of jewellery. In polishing, the idea is to add shine to the entire piece of jewellery. Polishing is done after setting of stones and it can be done either by hand or by machine. If the jewellery is hand polished, then the craftsman uses different tools like solid buff, soft buff, hair buff, coin buff, single line ball buff, green rouse for shine, platinum polishing rouse, black lustre for removing casting/filling layers, red rouse to impart shine and white lustre to remove roughness.

Step 14 – RHODIUM PLATING

Rhodium is a sparkling white coloured precious metal. When a piece of jewellery is plated with Rhodium, it gives a white reflective appearance and provides the piece of jewellery better resistance to scratches and tarnish. It is used on yellow gold for creating visually appealing patterns and designs. The use of Rhodium plating on white gold is meant for adding whiteness to the gold, since white gold is not so white in its original and pure form.

Step 15 – QUALITY CONTROL

Quality control (QC) is a procedure or set of procedures intended to ensure that a manufactured product or performed service adheres to a defined set of quality criteria or meets the requirements of the client or customer. There are three different methods of quality control inspection which includes include measurement, visual inspection and mechanical inspection.
