Picture this: you’re searching for the perfect piece to add sparkle to your everyday jewelry collection or trying to find the perfect wedding ring set for your upcoming nuptials. But with so many options, particularly when it comes to gemstones, the decision can be overwhelming. There are real diamonds, of course, plus an endless array of natural gemstones, like moissanite, and simulated diamonds. In recent years, more and more people have turned away from genuine diamonds in favor of simulated diamonds and moissanite.

But what is a simulated diamond, and how does it compare to moissanite? Both have surged in popularity as alternatives to traditional diamonds in everything from everyday earrings to stunning wedding ring sets, but they are two distinctly different stones. Let’s explore the characteristics of each to help you navigate the world of sparkling gemstones.

Simulated Diamonds

Simulated diamonds are not actual diamonds but rather synthetic materials crafted to mimic their appearance. The most common simulated diamond is cubic zirconia (CZ). This popular choice boasts a brilliance that rivals that of diamonds, making it a budget-friendly option for adding sparkle to everyday jewelry. CZ is created in laboratories under controlled conditions, resulting in a flawless and consistent product. While visually stunning, CZ falls short of diamonds in terms of hardness (around 8.5 on the Mohs scale), meaning it can be more susceptible to scratches with everyday wear.


Unlike simulated diamonds, moissanite is a naturally occurring gemstone, albeit a rare one. Discovered in the late 19th century by famed scientist Henri Moissan, it wasn’t until recently that advancements in technology allowed for it to be made in laboratories. Moissanite is a popular diamond alternative due to its exceptional brilliance. Additionally, moissanite boasts a hardness rating of 9.25 on the Mohs scale, making it nearly as hard as a diamond and ideal for everyday wear in rings and bracelets.

Head-to-Head: Simulated Diamond vs. Moissanite

Deciding between simulated diamonds and moissanite depends on your priorities. When it comes to brilliance, CZ offers a classic sparkle, similar to a diamond. Moissanite, however, boasts a fiery brilliance that displays flashes of rainbow colors. This play of light might be more captivating for those seeking a truly eye-catching gemstone.

Durability is another key factor. While both are significantly more durable than many other gemstones, moissanite takes the edge here. Ranking 9.25 on the Mohs scale, it’s nearly as hard as a diamond, making it ideal for everyday wear. CZ is still a good choice but might be more susceptible to scratches with frequent wear.

Cost is a significant advantage for both CZ and moissanite. They are considerably less expensive than mined diamonds, making them attractive alternatives. CZ is the most budget-friendly option, while moissanite’s price point lands between CZ and diamonds.

Finally, both simulated diamonds and moissanite offer peace of mind when it comes to ethical considerations. They are conflict-free alternatives to traditional diamonds, ensuring your dazzling piece wasn’t sourced through unethical mining practices.

So, what’s the bottom line? If classic sparkle and affordability are your main concerns, CZ might be the ideal choice. However, if you prioritize exceptional brilliance and durability for everyday wear, moissanite is a better fit.

Additional Factors to Consider

While brilliance and durability are crucial aspects, other factors come into play when selecting the perfect gemstone. Here are a few other things to consider:

  • Setting Options: The way a gemstone is set significantly impacts its overall look and brilliance. Prong settings, for example, allow more light to interact with the stone, maximizing sparkle.
  • Maintenance: Both CZ and moissanite require regular cleaning, like any gemstone. A soak in a solution of warm water and dish soap followed by gentle scrubbing with a soft cloth will keep your gem sparkling.
  • Personal Style: Consider the overall aesthetics you desire. Do you prefer the classic, timeless sparkle of CZ, or are you drawn to the fiery brilliance of moissanite? Ultimately, the best choice is the one that speaks to your personal style.
