A Comprehensive Guide to Comparing Cubic Zirconia and Diamonds

For decades, cubic zirconia, a diamond simulant, has been revered by jewel and gem enthusiasts and collectors, appreciated for its diamond-like appearance and properties. Paying homage to the skill of crafting CZ engagement rings, bracelets, earrings, and necklaces showcases state-of-the-art designs, masterful craftsmanship, finesse, and elegance, while also offering an affordable and accessible alternative to diamonds.

With a striking resemblance, owning the same brilliance, clarity, sparkle, and strength as that of diamonds, they can never be separated from a naturally mined gemstone via the untrained eye. But what exactly is cubic zirconia? And how well does it measure or rank against its natural counterpart? 

The guide here elaborately explores the immensely fascinating world of cubic zirconia, uncovering its unique properties, origins, and featuring an in-depth analysis of factors and benefits that encompass CZ. By the end of the article, you will have a clear understanding of why the diamond alternative has surged in popularity, becoming a sophisticated choice for modern jewelry enthusiasts. 

The History of Cubic Zirconia 

Most jewelry enthusiasts consider the formation of diamonds to be a process that has been forged deep within the Earth's surface over billions of years. The story of cubic zirconia, however, is relatively recent, with its origins dating back only a few decades. Propelled through controlled laboratory procedures, their roots are not in a mine, but rather they originated in a laboratory. 

From their Laser Technology Origins to Luxury Jewelry 

The natural form of zirconium dioxide was identified primarily in the 1930s by German mineralologists. The existence was so minuscule that it got overlooked at that time. It wasn't until the 1970s that Soviet scientists at the Lebedev Physical Institute in Moscow perfected a method to grow larger singular crystals, particularly of cubic zirconia. 

The primary aim was not to create jewelry. The scientists required a highly durable and optically flawless material, particularly one known for its use in laser technology. It was not long before someone recognized the watch’s true potential. 

The luxurious and mesmerizing appearance of a diamond-lookalike made it an undeniable presence. By the late 1970s, cubic zirconia had made a bold entry into the market, captivating the discerning CZ jewelry collectors with its comparatively affordable and accessible nature. 

The Sparkle and the Science Behind It 

A diamond is known by the sparkle it keeps! Interesting, isn’t it? The sparkle, along with its brilliance and clarity, makes the precious gemstone a distinctive choice that nurtures ornamental beauty. 

Cubic zirconia, the artificial crystalline form of zirconium dioxide, which, when in its natural state, crystallizes differently. To artificially imitate a diamond-like appearance depicting a cubic crystal structure, scientists must heat zirconium oxide to extremely high temperatures, reaching a temperature so high that no container can withstand it. 

The breakthrough moment came with the introduction of the "skull melt," a process that could utilize microwaves. Since microwaves heat from the inside out, the outer layer of zirconium oxide powder remains cool, thus forming its own crucible. The inside melts and recrystallizes into flawless gemstones, which are seen today. 

Cubic Zirconia and Diamonds- A Comprehensive Comparison

Although similar in terms of brilliance, sparkle, and clarity, cubic zirconia and diamonds have distinct differences. Let us explore them!

1. Durability and Hardness 

The most significant difference between cubic zirconia and diamonds is based on their durability and hardness. The Mohs scale of hardness is a measure of a gemstone’s resistance to scratches and abrasions. 

• Diamonds: Securing a perfect 10 on the Mohs scale, diamonds are the hardest known material. Tremendously resistant to scratches, dents, and abrasions, the naturally mined gemstone is aptly chosen for everyday wearability. 

• Cubic Zirconia: Securing a hardness rating of 8-8.5 on the Mohs Scale, it depicts a durable gemstone. Although not as hard as diamonds, CZ also resists scratches, dents, and abrasions. The diamond-lookalike proves to be a stunning alternative to diamonds, offering greater accessibility and affordability. 

2. Clarity and Imperfections

• Diamonds: Diamonds are naturally mined, forged for billions of years deep within the Earth’s mantle. Derived from nature, imperfections do appear and cannot be graded as flawless. Tiny internal flaws, known as inclusions or external blemishes. Remember, if graded flawlessly, diamonds with no imperfections are extremely rare and, if found, are highly valued and priced accordingly. 

• Cubic Zirconia: CZ is created in a controlled laboratory condition. Having been fabricated synthetically, CZ can be made virtually flawless, thus forging a clarity and brilliance similar to that of diamonds.

3. Weight and Density

When comparing naturally mined diamonds and their synthetic counterparts by holding them in your hands, a noticeable difference is evident in their weights.

• Cubic Zirconia: Is about 75% denser than a diamond. This means a 1-carat-sized CZ stone will weigh approximately 1.75 carats, making it noticeably heavier.

4. Fire and Brilliance

Fire refers to the dispersion of light into visible colors. These are colorful flashes of light. 

• Cubic Zirconia: Features a higher dispersion rate than diamonds. This very splitting of light into several colors results in rainbow-colored flashes. Though featuring ornamental beauty, this intense fire can sometimes be a giveaway that it is not a diamond.

5. Value and Cost

The price difference between the two gemstones is substantial.

• Diamonds: Are valued for their rarity and durability, and they retain their value over time, making them a significant investment.

• Cubic Zirconia: Offers the look of a diamond for a fraction of the cost, making it an excellent choice for fashion jewelry or for those who want a larger stone on a budget. However, its resale value is minimal, tied primarily to the metal of the setting.

FAQs

Could you identify the difference between cubic zirconia and diamonds?

The two wonders in the bedazzling world of gemstone jewelry-making are virtually inseparable. Displaying the same brilliance, clarity, and sparkle, it is nearly impossible for the untrained eye to spot the difference between diamonds and high-quality cubic zirconia. There are, however, professional and specialized tools used by gemologists and jewelers that identify the key differences between fire, weight, and slight imperfections.

How do I care for my cubic zirconia jewelry?

Taking care of your CZ jewelry is straightforward. Cleaning your CZ jewel piece regularly with a soft brush, warm water, and mild soap is crucial to removing excessive product buildup. The presence of dust, dirt, and oil, if left unnoticed, could reduce its sparkle. Because it is softer than natural diamonds and more prone to scratches and abrasions, it is essential to store it in a separate location. 

Is cubic zirconia the same as zircon?

No, they are different materials. Cubic zirconia is a man-made substance (zirconium oxide), while zircon is a natural gemstone (zirconium silicate). Zircon is also softer than CZ, with a Mohs hardness of about 6.5 to 7.5.
