Cubic Zirconia is a popular alternative to diamonds for its affordability and brilliance. It has become a widely used gemstone in the jewelry industry, with its crystal-clear appearance and remarkable brilliance. It mimics diamonds in terms of similarities in appearance.
But have you ever wondered how is cubic zirconia made? Well, it may surprise you to learn that this stunning gemstone is not formed naturally but rather created in a laboratory using advanced techniques.
In this article, we will explore the fascinating process of creating this synthetic gemstone, from the initial raw materials to the finished product, and shed light on the secrets behind its beauty. Understanding how cubic zirconia is made can give us a better appreciation for its qualities and the effort involved in its production.
Manufacturing Process Overview
To understand how cubic zirconia is made, let’s take a closer look at the manufacturing process. It involves several key steps that transform raw materials into beautiful gemstones.
Mixing the Ingredients
To make cubic zirconia, the first step is to mix the required ingredients. These usually consist of zirconium oxide and other substances that help stabilize the mixture.1 The ingredients are carefully measured and combined to create a smooth and even blend.
Forming the Stones
Once the ingredients are mixed, they are shaped into small seed crystals or larger blocks through a process called crystallization. This can be done using various methods, such as the Skull Melt technique or the Czochralski process. The seed crystals serve as a foundation for growing larger cubic zirconia stones.
Heat-Treating the Stones
After forming, the stones undergo heat treatment to enhance their optical properties and remove any impurities. This involves subjecting them to high temperatures in controlled environments. Heat treatment helps improve clarity, color, and overall quality of the cubic zirconia stones.
Grinding and Polishing
Next, the stones go through grinding and polishing stages to achieve their desired shape and brilliance. Highly skilled craftsmen use specialized equipment to carefully shape and facet each stone. This meticulous process ensures that every cubic zirconia stone exhibits exceptional sparkle and beauty.
Quality Assurance Testing and Final Product Packaging
Before being packaged for sale, each cubic zirconia stone undergoes rigorous quality assurance testing. This includes assessing its color, clarity, cut, and overall appearance to ensure it meets strict standards of excellence. Once approved, the stones are meticulously packaged with care to protect their shine during transportation.
Raw Materials Used
To create cubic zirconia, several raw materials are used in the manufacturing process. Let’s take a closer look at each one:
Zirconium Oxide Powder
The primary ingredient in cubic zirconia is zirconium oxide powder. This fine white powder serves as the base material for creating the gemstone. It is derived from natural minerals like baddeleyite or synthetic sources such as zirconium chloride. The zirconium oxide powder undergoes a series of chemical reactions and heating processes to transform it into the crystal structure of cubic zirconia.
Colorants are added to the zirconium oxide powder to give cubic zirconia its vibrant hues. These colorants can be metallic oxides or other compounds that introduce specific colors into the gemstone. For example, adding chromium oxide creates a green color while cobalt oxide produces a blue shade. By carefully controlling the amount and type of colorant, manufacturers can create a wide range of colors for cubic zirconia.
Binders and Sealants
Binders and sealants play an essential role in holding together the various components during the manufacturing process. They help to bind the zirconium oxide powder and colorants together, allowing them to form a solid mass that can be shaped and cut into gemstones. Sealants are applied to protect the surface of cubic zirconia from scratches or damage.
