What is cubic zirconia?
Cubic zirconia, often abbreviated as "CZ," is a synthetic stone created in a laboratory. Discovered in the 1930s by Soviet scientists, it wasn't widely produced until the 1970s. It was developed as an alternative to diamonds, seeking to offer similar brilliance while being more affordable.
Unlike its natural counterpart, zirconite, which is a rare mineral, cubic zirconia is lab-made from zirconium oxide, making it purer, free of inclusions, and exceptionally clear. While cubic zirconia is not a natural stone, its careful craftsmanship gives it a brilliance comparable to that of diamonds.
The History of Cubic Zirconia: From Discovery to Jewelry Revolution
Cubic zirconia was discovered through research by Soviet scientists in the 1930s . However, its large-scale production was developed thanks to technological advances only in 1976. by a team of scientists led by Soviet chemist Aleksandr V. Finkelstein. The researchers were looking for a synthetic, economical, and visually similar alternative to diamond. It was only after many years of experimentation that an effective manufacturing method was established. Cubic zirconia quickly gained popularity in the 1980s, particularly for costume jewelry and fashion accessories.
Which are the producing countries?
Nowadays, cubic zirconia is produced on a large scale, mainly in China which largely dominates the market with specialized factories that master crystallization techniques to obtain stones of exceptional purity and brilliance. Other countries like the United States, Russia and India are also major players in the production of this synthetic stone.
Main characteristics of cubic zirconia
| Property | Detail |

| Density | 5.6 - 6 |
| Refractive index | 2.15 - 2.18 |
| Available colors | Transparent, blue, red, green, yellow, pink |
| Scratch resistance | Good, but inferior to diamond |
| Price | Very affordable |
Compared to diamonds, cubic zirconia is less hard and can scratch more easily. However, it remains extremely brilliant and is often used as an alternative to more expensive gemstones.
Manufacturing Cubic Zirconia: A Precise and Complex Process
How is cubic zirconia made?
The manufacture of cubic zirconia relies on a complex and meticulous process called fusion-stabilized growth . This process which requires advanced technologies guarantees a perfect stone, without inclusions or imperfections.
Here are the key stages of manufacturing:
-
Mixing oxides : Zirconium oxide is combined with other stabilizing elements, such as yttrium oxide or calcium oxide , to ensure its crystalline structure.
-
Intense heating : This mixture is heated to extreme temperatures, up to 2,750°C, to melt the zirconium oxide.
-
Controlled crystallization : By gradually cooling, the material solidifies, forming perfectly cubic crystals, which will then be cut and polished.
-
Cutting and Polishing : The resulting cubic crystals are cut using methods similar to those used for diamonds. Cutting is crucial to maximize brilliance and light reflection.

The Different Colors of Cubic Zirconia: A Dazzling Palette
One of the greatest advantages of cubic zirconia is its ability to be manufactured in a variety of colors. Depending on the elements added during the manufacturing process, zirconia can take on hues ranging from bright white to deep red, including colors such as blue, green, and yellow. These colors are achieved through a process of heat and chemical treatment of zirconia crystals.
-
White zirconia vs. diamond: White cubic zirconia is often compared to diamond because of its brilliance and ability to reflect light. However, unlike diamond, it is less hard and can scratch more easily.
-
Green Zirconia vs. Emerald: Green cubic zirconia is prized for its crystal clarity, which sometimes surpasses that of natural emerald, which is usually characterized by visible inclusions.
-
Red Zirconia vs. Ruby: Well-cut red cubic zirconias can rival mid-quality rubies in brilliance, while being much more affordable.
-
Blue Zirconia vs. Sapphire: Blue zirconia is highly prized for its clarity, occasionally surpassing natural sapphire which may exhibit slight cloudiness.
Pink zirconia offers a luminous sparkle and an elegant hue. A refined alternative to sapphire.
Comparison with other Gemstones: Cubic Zirconia in All Similarities
-
Unparalleled brilliance: The main advantage of cubic zirconia over natural gemstones is its exceptional brilliance. With a refractive index of 2.18, it can surpass diamonds in some cases, although it is less hard and therefore more susceptible to scratching.
-
Unbeatable Value for Money: Unlike gemstones, cubic zirconia is much more affordable while still offering brilliance and beauty that can deceive the eye.
Cubic Zirconia Maintenance: Keep Its Sparkle for Years
