The art of jewelry making dates back thousands of years, to a time when ancient civilizations crafted jewelry for personal adornment. Created to display gemstones, express faith, and signify social status, artisans made jewelry that ranged from shells on hemp strings to tiaras and crowns worn by royalty.
Throughout the ages, the continual discovery of new gems, precious metals and ornamental materials, combined with advancement of tools and metallurgy, have made it possible for almost everyone to own fine jewelry. The following is the process of making gold jewelry!
STEP 1
A specific team of people are at the heart of creating the beautiful gold jewellery we all wear; they are the jewellery designers. The entire process starts with these guys.
The jewellery designer first digitally render the design of jewellery; be it an earring or a necklace on specialised software such as 3D CAD. These files are versatile and show how the product will look in reality, upon completion.
STEP 2
The final quality-checked 3D CAD file is then sent to the 3D printer. This is the first step in converting what was only a digital design idea to something that can actually be touched and felt; a 3D wax model of the jewellery piece.
This wax mould of the jewellery is the beginning of the process for creating a mould.
STEP 3
The wax mould of the jewellery is placed inside a box and resin; a rubber-like material is poured into the box, covering the wax mould completely.
Once the box is filled with resin, it is pressurised and hardened. This process leads to the wax mould being tightly airlocked within the resin.
The next is heating the box and its contents; this leads to the wax melting away, leaving a jewellery shaped cavity in the resin.
STEP 4
The cavity is then injected with hot molten wax. The wax is allowed to cool and settle down in the mould. The hardened wax is then removed from the cavity in the shape of the jewellery piece.
STEP 5
The next step is a process called investment casting. Here the hardened wax piece of jewellery is placed inside a hot furnace and covered in a material like POP.
Every available gap inside the furnace area is covered in POP except for the bit where the wax jewellery piece exists.
Here the furnace is heated, allowing for the wax jewellery to melt, leaving in its place a cavity in the POP that is then used to create the gold jewellery.
STEP 6
Into the cavity in the POP and quickly cooled, resulting in the gold taking the shape in the cavity. The furnace is opened and the hardened POP is taken apart leaving the gold cast jewellery.
The gold jewellery product is now almost complete.
STEP 7
Any rough edges or excess bits of gold is removed in polishing. Any addition, placement of gemstones, etc., happen after this stage.
There will be grooves in this piece of gold jewellery if it is supposed to have gemstones carefully placed in them.
This is a time-consuming activity involving fine skill and focus, depending on the design and setting of the gemstones.
They also need to be fixed in a durable and reliable manner as no one wants loose gemstones!
STEP 8
The final jewellery product after being polished and cleaned goes through a series of quality checks before it is ready to be delivered to the customer.
