When searching for an engagement ring or fine jewelry, the options can seem endless. Diamonds are the traditional and highly coveted choice, but their steep price tags often put them out of reach for many shoppers. Fortunately, there are stunning diamond alternatives that offer exquisite brilliance and fire at a fraction of the cost – moissanite and cubic zirconia.
Both moissanite and cubic zirconia are lab-created gemstones that closely resemble diamonds in their appearance. However, these two gems have distinct properties that set them apart, from their optical characteristics to their durability and value. As a gem and jewelry expert at Shelby Gem Factory, I’ll delve into the nuances of moissanite and cubic zirconia, empowering you to make an informed decision that aligns with your style, budget, and personal preferences.
Gemstone Characteristics
Optical Properties
At the heart of any gemstone’s allure lies its optical properties. Both moissanite and cubic zirconia exhibit brilliant, diamond-like sparkle, but the similarities largely end there.
Moissanite boasts a higher refractive index of 2.65-2.69, compared to diamond’s 2.42 and cubic zirconia’s 2.15-2.18. This means that moissanite has a superior ability to bend and refract light, resulting in an unparalleled display of fire and brilliance. The dispersion of moissanite, which is the separation of light into its spectral colors, is also higher at 0.104, lending it a captivating “disco ball” effect.
In contrast, cubic zirconia, while still quite brilliant, falls short of moissanite’s optical performance. Its lower refractive index and dispersion values create a more subdued, less fiery sparkle. Some may find the intense brilliance of moissanite to be overpowering, preferring the more subtle sparkle of cubic zirconia.
Chemical Composition
The core difference between moissanite and cubic zirconia lies in their chemical makeup. Moissanite is a synthetic form of silicon carbide, a naturally occurring mineral first discovered in a meteorite crater by French chemist Henri Moissan in 1893. Cubic zirconia, on the other hand, is a lab-created crystalline form of zirconium dioxide.
The unique chemical structure of moissanite contributes to its exceptional optical properties and durability. Cubic zirconia, while also a synthetic gemstone, lacks the inherent strength and fire of moissanite.
Durability
Durability is a crucial factor when selecting a gemstone, especially for everyday wear like engagement rings or jewelry. Here, moissanite shines, with a Mohs hardness of 9.25 – second only to diamond’s 10. This makes moissanite highly resistant to scratches, chips, and other forms of wear and tear.
Cubic zirconia, with a Mohs hardness of 8-8.5, is still relatively durable, but it is more susceptible to scuffs and abrasions over time. While both gems are hard enough for daily use, moissanite’s superior hardness ensures it will maintain its brilliant sparkle for years to come.
Moissanite Overview
Origin and Discovery
The fascinating history of moissanite begins with its accidental discovery in a meteorite crater in Arizona by Nobel Prize-winning chemist Dr. Henri Moissan in 1893. Moissan initially believed the tiny, shimmering crystals he found were diamonds, but further analysis revealed they were a new mineral composed of silicon carbide.
This extraterrestrial origin has captivated the imagination of many, lending moissanite an air of cosmic allure. Today, all moissanite used in jewelry is lab-created, as the natural form is extremely rare and found only in minute quantities.
Physical Attributes
Moissanite’s physical properties make it a truly remarkable gemstone. In addition to its unparalleled brilliance and fire, moissanite also boasts exceptional hardness, thermal conductivity, and clarity. These factors contribute to its durability and longevity, making it an exceptional choice for engagement rings and other fine jewelry.
While moissanite is typically colorless, it may exhibit faint yellow or grayish hues, depending on the quality and production process. High-end moissanite, however, can appear entirely colorless, closely mimicking the appearance of a diamond.
Moissanite Certification
To ensure the authenticity and quality of moissanite, it is essential to purchase stones that have been certified by reputable gemological laboratories, such as the Moissanite International (MI) or the American Gem Society (AGS). These certifications provide assurance of the gemstone’s origin, cut, clarity, and other key characteristics, allowing consumers to make informed purchasing decisions.
Cubic Zirconia Overview
History and Synthesis
Cubic zirconia has a much more recent history compared to moissanite. It was first synthesized in 1937 by German mineralogists, who created the crystalline form of zirconium dioxide in a laboratory setting. Unlike moissanite, cubic zirconia does not have a naturally occurring counterpart.
The development of commercial-scale production methods in the 1970s made cubic zirconia a widely available and affordable diamond alternative. Today, it is one of the most commonly used simulated diamonds in the jewelry industry.
Visual Appearance
Cubic zirconia is known for its remarkable visual similarity to diamond. It can be found in a range of colorless or tinted varieties, with the colorless versions closely mimicking the appearance of high-quality diamonds. However, cubic zirconia lacks the exceptional fire and brilliance of moissanite, appearing slightly less dazzling in comparison.
Cubic Zirconia Certification
While cubic zirconia is not typically certified in the same way as moissanite or diamonds, reputable jewelers may provide their own assurances about the quality and origin of the stones they sell. Consumers should always request documentation or certificates to ensure they are purchasing authentic cubic zirconia from a reliable source.
Brilliance Comparison
Fire and Sparkle
The captivating display of light and color is a key aspect of any gemstone’s allure. In this regard, moissanite excels, with its exceptional fire and sparkle that can often outshine even the finest diamonds.
Moissanite’s high refractive index and dispersion values create a stunning “disco ball” effect, with flashes of rainbow-like colors that captivate the eye. Cubic zirconia, while still quite brilliant, appears more subdued in comparison, with a less fiery, more whitish sparkle.
Light Refraction
The way a gemstone refracts and bends light is a crucial determinant of its brilliance and visual appeal. Moissanite’s superior refractive index of 2.65-2.69 allows it to bend light more efficiently than cubic zirconia’s 2.15-2.18, resulting in a greater display of sparkle and scintillation.
This difference in light refraction is immediately noticeable, with moissanite appearing more luminous and diamond-like than the slightly more muted sparkle of cubic zirconia.
Dispersion
Dispersion, the separation of white light into its constituent spectral colors, is another key factor that contributes to a gemstone’s brilliance. Moissanite’s dispersion value of 0.104 is significantly higher than cubic zirconia’s 0.058-0.066, leading to a more vibrant, rainbow-like display of fire.
This enhanced dispersion is a primary driver of moissanite’s captivating “disco ball” effect, which can be both mesmerizing and, for some, overwhelming. Cubic zirconia, with its lower dispersion, exhibits a more subdued, whiter sparkle.
