Jewelry Shine Secrets

What is important when choosing jewelry accessories? Price, quality, design – each buyer has his own selection criteria. But the first thing that a person who has crossed the threshold of a jewelry store pays attention to is how attractively the accessories placed on the window sparkle. Before a jewelry made of precious metal gets into the salon, it goes through many stages of production. The key task of the master is not only to bring to life an interesting idea, but also to make the accessory shine. We will tell you what polishing, tumbling and polishing of gold products are, and we will teach tricks that will prevent the radiance of your jewelry from fading over the years.

How jewelers achieve brilliance of jewelry
Jewelry making is a lengthy process. First, an idea is born – a sketch. Then the accessory is cast from gold or silver (give the material a specific shape). But the working process does not end there: in the foundry, only the first stage of production is completed. It is further important that the bends become soft and the surface sparkling.

How to achieve shine of accessories? Finishing work helps to make the decoration flawless – grinding, tumbling, polishing. Only after passing through these stages, the jewelry accessory becomes perfect and gets to the showcase, where it finds its owner. Let’s try to understand in more detail how jewelers manage to achieve mirror smoothness and incredible brilliance of jewelry.

Grinding

The first step to flickering precious metal is grinding. This stage of production immediately follows the casting. Molded jewelry is still far from perfect, and polishing allows you to approach the ideal. Thanks to the procedure:

the product receives exact forms;
excess metal is removed;
the surface of the accessory is cleaned and becomes flat.
Grinding of gold and silver is carried out using a special machine. The equipment has a grinding wheel. After the circle begins to work, the master brings the cast product to it to remove excess metal from the model. It is necessary to act extremely carefully: it is important not to harm the designed form of the accessory.

Grinding silver and gold is the finest work. Using the machine, you can work out only the general surface, and to adjust the smallest elements you will need a hand tool. The jeweler uses a drill, which is equipped with a huge variety of nozzles, often a file is used. Making a mistake using a grinding wheel is easy, but the risks of making a mistake during manual grinding increase at times. It is important that the master is as focused on his work as possible, because it is truly filigree.

Grinding does not make the decoration perfect, but brings this moment closer. After grinding work, the product proceeds to the next production stage.

Tumbling

To make the accessories almost the way buyers see them in the store, a tumbling is carried out. This procedure is needed to clean the model, level the surface and give shine to the accessory. Tumbling jewelry combines grinding and polishing.

Tumbling technology involves the availability of special equipment. The final result depends on its level and on strict adherence to instructions. Tumbling is usually carried out in two stages: raw processing (grinding) and dry (polishing). Sometimes only the “dry” stage is enough, but only the master can accurately determine the number of treatments.

The first stage of tumbling is carried out as follows:

Cast jewelry is placed in a special drum.
A special solution containing reagents is also poured here. Their role can be played by solutions of soda ash, sodium hydroxide, slaked lime and special polishing preparations and detergents. Reagents accelerate the metal cleaning process.
Special balls are placed in the drum for jewelry and buffer solution. They are made of steel and are small in size.
Set the time of tumbling, speed – and start the equipment. The drum starts to spin.
After the drum stops, its contents are poured into a special container resembling a large sieve. The solution and balls go away, the cleaned accessories remain in the “network”.

After wet processing, dry is carried out. The principle is the same, however, dry abrasives are used instead of solutions. It can be porcelain, corundum, plastic, ceramics in the form of small geometric figures – a cone, a cylinder, a ball. Sometimes tacklers use chopped nutshells: it copes with polishing no worse than synthetic abrasives. Experts set the parameters on the equipment: it depends on how carefully the products will be polished and whether the accessories elements will be damaged.

In jewelry practice, most often only dry tumbling is carried out. Cast products are cleaned of excess on the machine and using hand tools. But sometimes manual grinding is replaced with crude tumbling. This allows you to reduce the cost of the product, because for manual labor you always have to pay dearly.
