Cubic zirconia has emerged as a popular and accessible gemstone, particularly within the realm of contemporary jewelry. While not a naturally occurring birthstone in the traditional sense, its widespread use and diamond-like qualities have cemented its place as a significant material in the jewelry market. This article will explore the characteristics of cubic zirconia, its various cuts, care guidelines, and its role as a versatile and affordable alternative to more precious gemstones.
History and Lore
The history of cubic zirconia is relatively recent compared to that of naturally mined gemstones. It was first created in 1972 by a team of scientists at the Max Born Institute in Germany. While initially discovered as a rare mineral in nature, the synthesized form is what gained prominence. The development of cubic zirconia was not driven by historical lore or ancient beliefs, but rather by a desire to create a convincing diamond simulant. Its introduction provided an affordable option for those seeking the aesthetic appeal of a diamond without the associated cost. The provided sources do not detail any specific historical or cultural significance beyond its role as a modern gemstone alternative.
Geological Formation and Sources
Unlike naturally occurring gemstones formed over millennia through geological processes, cubic zirconia is entirely synthetic. It is produced in a laboratory through a controlled process involving the melting and crystallization of zirconium dioxide powder. The sources do not provide details on the specific manufacturing processes or the locations of production facilities. As a lab-created stone, it does not have traditional mining locations associated with it.
Gemological Properties
Cubic zirconia (ZrO₂) is a crystalline material known for its high refractive index and dispersion, giving it a brilliance and fire comparable to that of a diamond. However, it differs significantly in hardness and density. The sources focus primarily on the various cuts available for cubic zirconia, highlighting how these cuts affect the stone’s appearance.
Several cuts are commonly used for cubic zirconia, each with its own characteristics:
- Asscher Cut: Also known as a square octagon, this cut features large step-cut facets best displayed in stones 1.50 carats or larger. It is symmetrical, with equal length and width.
- Cushion Cut: The sources do not provide details on this cut.
- Emerald Octagon Cut: The sources do not provide details on this cut.
- Heart Cut: Shaped like a stylized heart, this cut is favored for its unique shape rather than its brilliance, which is lesser than many other cuts due to light refraction. It is commonly used for promise rings and gifts. However, the pointed tip is prone to chipping and breakage. The heart cut is not symmetrical, but designed to have equal length and width across a "T" from the middle.
- Marquise Cut: This elongated cut is less commonly requested and often used as an accent stone. It is visually striking when placed vertically above a wide-banded ring. It is also prone to chipping at its pointed tips and is more difficult for jewelers to work with due to its fragile corners and shape. The marquise cut is elongated, with non-equal length and width.
- Oval Cut: The sources do not provide details on this cut.
- Pear Cut: Also known as a teardrop cut, this brilliant-cut stone is often used as an accent stone. Like the heart and marquise cuts, its popularity stems from its shape rather than its brilliance. It also has a pointed tip susceptible to chipping. The pear cut is elongated, with non-equal length and width.
- Princess/Square Cut: The sources do not provide details on this cut.
- Radiant Octagon Cut: The sources do not provide details on this cut.
- Round Cut: The sources do not provide details on this cut.

A table summarizing the cuts and their key characteristics, based on the provided sources, is as follows:
| Cut | Shape Description | Brilliance | Durability Concerns | Common Use | Symmetry |
|---|---|---|---|---|---|
| Asscher | Square Octagon | High | None | Larger Stones | Symmetrical |
| Heart | Stylized Heart | Moderate | Pointed Tip | Promise Rings, Gifts | Asymmetrical |
| Marquise | Elongated | Moderate | Pointed Tips | Accent Stones | Asymmetrical |
| Pear | Teardrop | Moderate | Pointed Tip | Accent Stones | Asymmetrical |
Symbolism and Metaphysical Beliefs
The provided sources do not contain any information regarding the symbolism or metaphysical beliefs associated with cubic zirconia. Its value is primarily aesthetic and economic, functioning as a cost-effective alternative to diamonds and other gemstones.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of cubic zirconia jewelry. The sources recommend removing jewelry before physical activity, rigorous manual labor, sleeping, swimming, or showering. Avoiding harsh chemicals, lotions, and oils while wearing the jewelry is also advised. Bi-annual professional inspections and repairs are recommended, and any loose prongs or stones should be addressed promptly.
For routine cleaning, a gentle soap, warm water, and a soft toothbrush can be used. Soaking the jewelry for 10 minutes, gently scrubbing, and rinsing thoroughly is suggested. For oil buildup, cleaning with a silver polish, such as Wright's Silver Cream, is recommended. Professional cleaning once a year is also advised.
Market Considerations
The sources mention a $10 setup fee for purchases and the option of a layaway plan with no interest. They also highlight the availability of complimentary professional cleanings on all Zen Moissanite jewelry, which suggests a connection or overlap between the two brands. The sources indicate that the heart, marquise, and pear cuts are less popular choices for center stones, while the asscher cut is best displayed in larger sizes. The sources also state that cubic zirconia is the #3 most popular stone in sales.
Conclusion
Cubic zirconia has established itself as a significant player in the gemstone market, offering an affordable and visually appealing alternative to diamonds and other precious stones. Its versatility in cuts, ease of maintenance, and relatively low cost make it a popular choice for a wide range of jewelry designs. While lacking the historical lore of natural gemstones, cubic zirconia’s modern appeal and enduring brilliance continue to attract consumers seeking both beauty and value.
