Now, let me show you how we make our own jewelry to customers. A jewelry production involves three main words as below:


Jewelry making begins with a mold, and all molds cannot exist without a sketch at the first place. After the sketch is drawn by our designer, our factory will create a new mold aid by CAD computer design.

A mold is the exact and perfect replica of the piece to be made, copied either from a design or an object. A mold is shaped around the figure with the help of casting process. The method of casting that we use is investment casting. The casting process involves a number of steps.

Investment Casting

Investment Casting is also called 'lost wax casting' since the wax is removed by heating in a kiln or in an autoclave. It is the earliest metal technique evolved by mankind and has a history of 4,000 years.

Believed to have been developed by the Mesopotamians, it remains the most popular process of making gold or metal jewelry and forms the basis of modern investment casting process. This process involves dipping a mold into a ceramic mix. Sometimes new materials like plastic or polystyrene foam is used instead of wax. This process has a number of steps involved.

  1. A primary model is made in hard alloy like nickel silver or just silver.
  2. A rubber model is made by surrounding this primary model, using sheet rubber in a mold frame. It is then vulcanized by placing it in a heated press. On cooling, it is cut with a scalpel into halves or more and removing the primary model.
  3. This rubber mold is used to make many copies of the primary model on wax.
  4. Molten wax is then introduced into the mold cavity by using a wax injector. On cooling the wax is removed to get an exact copy of the primary model in wax.
  5. After the desired number of models has been made the waxes are arranged in a tree all around a central feeder in the casting machine. The central feeder is also called sprue. The tree placed in a metal cylinder called flask.
  6. A special mixture called investment plaster is mixed with water to form a thick liquid and poured over the tree covering the wax models. Low vacuum removes air bubbles and then this is allowed to cool and harden to form stiff and sturdy molds.
  7. Then the flask is inverted and placed in a kiln/furnace. The wax is melted by steam or air to remove all the wax. The furnace is set in stages and the maximum temperature reached is 750 degrees centigrade. The melting process takes about 12 to 16 hours. This melting down of the wax is called the 'lost wax process'.
  8. The wax is slowly melted and drained out completely and all that is left behind is the investment plaster mold and this will now be used to pour the required molten metal (to be cased) into.
  9. The casting process begins by putting the flask in a casting machine. The gold metal or its alloy is melted and then cast into the investment mold. Then it is allowed to cool and solidify.
  10. After it has cooled down completely it is immersed into cold water which breaks off the investment mold, leaving the casts in the tree. The casting are cut off and then made into jewelry pieces called gold casing which are ready for the next step.


Micro Setting

Our gold casing cannot leave without diamonds. Usually we use micro setting for setting diamonds.

Micro setting is a kind of hand fabrication. The micro setting technique uses a large amount of very small diamond stones and puts them in a setting in which they are very close together. Usually in a white metal, gold and silver jewelry, this gives a very glittering and eye catching effect to the jewelry. This type of jewelry is so glamorous and beautiful that it can be worn with just about any outfit on any occasion.

Micro setting has become very popular with costumer shopping for band rings, wedding rings, engagement and anniversary rings, bangles, pendants, and earrings. The delicate and brilliant appearance that it creates is something never seen before in the jewelry industry.

Our worker with set diamonds one by one in the gold casing, it may take few hours or few days to finish the progress for a single piece. After that, a finished good will then is polished into completion.
