When it comes to choosing an engagement ring, the decision between moissanite and diamond can be difficult. Both gemstones have their own unique qualities and characteristics that make them appealing to different individuals. This article aims to provide a comprehensive comparison of moissanite and diamonds, outlining the key differences and benefits of each option.

Moissanite is a lab-created mineral called silicon carbide, while diamonds are naturally occurring. While diamonds have long been the traditional choice for engagement rings, moissanite has gained popularity due to its affordability and stunning brilliance.

Let’s delve deeper into the comparison between moissanite and diamonds, considering factors such as price, brilliance, durability, resale value, and more.

Key Takeaways:

  • Moissanite is a lab-created mineral, while diamonds are naturally occurring.
  • Moissanite is considerably cheaper than diamonds, making it a more budget-friendly choice.
  • Diamonds are known for their durability and hardness, ranking a 10 on the Mohs scale, while moissanite ranks slightly below.
  • Moissanite has more sparkle and fire than diamonds, making it incredibly eye-catching.
  • Moissanite offers a more affordable price point and larger sizes compared to diamonds.

Moissanite Price vs Diamond Price

One of the biggest advantages of choosing moissanite over a diamond is the price. Moissanite stones are significantly cheaper than diamonds of the same size and quality. In fact, a moissanite gem is approximately one-tenth the cost of a mined diamond of equal size and quality. This price difference becomes more significant with larger carat weights. So, if you’re looking for a large-carat white gemstone but don’t have the budget for a diamond, moissanite is a more affordable option.

Lower quality, smaller diamonds tend to cost more than higher quality, larger moissanite stones. When it comes to price, moissanite is a clear winner.

Price Comparison: Moissanite vs Diamond

Gemstone Size (in carats) Price Range
Moissanite 1 carat $500 – $1,000
Diamond 1 carat $3,000 – $6,000
2 carats $10,000 – $20,000

As seen in the table above, moissanite offers a significant cost advantage compared to diamonds. You can get a 1-carat moissanite for as low as $500, whereas a diamond of the same size would cost between $3,000 and $6,000. Even with larger carat weights, moissanite remains a more affordable option. Keep in mind that these prices are approximate and can vary depending on factors such as quality and retailer.

Whether you’re working with a tight budget or simply looking for the best value for your money, moissanite offers a cost-effective alternative to diamonds. By opting for moissanite, you can save a significant amount while still enjoying the beauty and elegance of a sparkling gemstone.

Moissanite Durability vs Diamond Durability

When it comes to choosing an engagement ring stone, durability is a vital consideration. Diamonds have long been celebrated for their exceptional durability and hardness, scoring a perfect 10 on the Mohs scale. They can withstand various forms of wear and tear, remaining resistant to scratches over time. On the other hand, moissanite is the second hardest mineral after diamonds on the Mohs scale, with a ranking of 9.25-9.5. While not as hard as diamonds, moissanite is still a highly durable stone and is less likely to scratch compared to other gemstones.

Both diamonds and moissanite are suitable for everyday wear, making them ideal for engagement rings that symbolize lifelong commitment. However, it’s worth noting that diamonds have a slight edge in terms of durability due to their top-ranking on the Mohs scale.

“Diamonds are incredibly durable and can withstand almost any form of wear and tear. Moissanite, although not as hard as diamonds, still provides excellent durability, making it a reliable choice for engagement rings.”

Regardless of whether you choose a diamond or moissanite for your engagement ring, you can be confident that both stones will maintain their beauty and integrity over time. The decision ultimately boils down to personal preference and factors such as budget and aesthetics.

Comparison of Durability:

Diamonds Moissanite
Durability 10 on the Mohs scale 9.25-9.5 on the Mohs scale
Resistance to Scratches Highly scratch-resistant Less likely to scratch compared to other gemstones
Suitability for Everyday Wear Excellent Excellent

As shown in the table above, diamonds score higher in terms of durability on the Mohs scale and are highly resistant to scratches. However, moissanite still boasts considerable durability, making it a reliable choice for those seeking a durable and beautiful engagement ring.

Moissanite Brilliance vs Diamond Brilliance

When it comes to comparing moissanite and diamonds, brilliance plays a crucial role. Moissanite outshines diamonds in terms of brilliance, with its ability to reflect more light and create a dazzling sparkle. The double dispersion value of moissanite means it exhibits a greater fire, displaying vivid spectral colors. When you rotate a moissanite stone, you’ll witness a mesmerizing rainbow-like effect. On the other hand, diamonds reflect a whiter light, showcasing a more classic and traditional look.

The difference in brilliance is most noticeable in larger moissanite stones, where the play of light is more pronounced and captivating. The extraordinary sparkle of moissanite can truly make a statement and catch the eye. If you prefer a stone that exudes more sparkle and brilliance, moissanite is the perfect choice for you.

Moissanite Color vs Diamond Color

When it comes to the color of gemstones, both moissanite and diamonds offer a range of options to suit your preferences. Traditionally, moissanite stones had a slight yellowish or greenish tint. However, advancements in the creation process now allow for the production of high-quality colorless moissanite, offering a more diamond-like appearance.

On the other hand, the color of diamonds can vary greatly and is graded on a scale. The most highly valued diamonds are colorless, with the highest clarity grade. However, it’s worth noting that the color differences between diamond grades may not be noticeable to the untrained eye.

Ultimately, the choice of color between moissanite and diamonds is subjective and dependent on personal preference and the aesthetic you’re looking to achieve. Whether you prefer the colorless brilliance of a diamond or the versatility of moissanite, both options allow you to create beautiful and unique styles for your engagement ring.

Moissanite Color vs Diamond Color Comparison

Moissanite Diamond
Colorless Colorless (highest value)
Near Colorless Near Colorless
Slightly Tinted Slightly Tinted
Yellowish or Greenish Tint Various Color Grades

In the end, whether you choose moissanite or diamonds, the color grade can be tailored to your desired style, allowing you to create a stunning engagement ring that reflects your unique taste and personality.

Moissanite vs Diamond Size

Size is often a crucial consideration when selecting an engagement ring stone. In this aspect, moissanite offers a significant advantage over diamonds. With the same budget, moissanite allows you to purchase a larger gemstone compared to diamonds, providing an opportunity for a more visually striking centerpiece without straining your finances.

For example, let’s say you have a budget of under $1,000. With this amount, you can buy a one-carat moissanite stone. However, if you were to opt for a diamond of the same size, it would cost you at least $3,000. This significant cost disparity allows you to enjoy a larger and more impressive moissanite gemstone within the confines of your budget.

Choosing moissanite over a diamond grants you the advantage of size, enabling you to flaunt a show-stopping engagement ring without breaking the bank.

Moissanite Resale Value vs Diamond Resale Value

When it comes to the resale value of gemstones, diamonds have a clear advantage over moissanite. Diamonds are renowned for their enduring value and have a well-established resale market. Unlike moissanite, diamonds have a longstanding history as a valuable investment and are often passed down through generations.

While moissanite can still be sold, it’s important to understand that it doesn’t hold the same value over time as diamonds. Due to the differences in rarity and perception, moissanite is unlikely to retain its original value when resold.

When it comes to the resale market, diamonds have an edge. They have a consistent demand and are recognized worldwide as a symbol of luxury and wealth. This demand contributes to their ability to retain value over time.

On the other hand, although moissanite offers an affordable alternative to diamonds, it does not have the same level of recognition and status in the resale market. This means that the resale value of moissanite may not be as significant as that of diamonds.

It’s important to note that the value of moissanite depends on the quality of the stone and other factors such as the overall condition of the jewelry. While moissanite may not hold its value as well as diamonds, it can still be a beautiful and affordable choice for those looking for an alternative to traditional diamonds.

If resale value is a significant factor for you, diamonds are the better choice. However, it’s essential to consider your personal preferences and budget when selecting a gemstone for your jewelry.

Diamonds Moissanite
Resale Value Has a well-established resale market and retains value over time. Does not hold the same value over time as diamonds.
Recognition Recognized worldwide as a symbol of luxury and wealth. Not as widely recognized and lacks the same status in the resale market.
Demand Consistent demand contributes to its ability to retain value. May not have the same level of demand and recognition in the resale market.

Moissanite Sustainability vs Diamond Sustainability

Sustainability is an increasingly important factor for consumers when selecting jewelry. When comparing moissanite and diamonds, moissanite emerges as the more sustainable option. While diamonds are mined from the earth, moissanite is created through a controlled lab-grown process. This distinction has significant implications for ethical and environmental considerations.

Diamond mining has long been associated with ethical concerns, including exploitative labor practices and environmental damage. The extraction process can lead to habitat destruction, water pollution, and soil erosion. Additionally, the industry’s opaque supply chain can make it difficult to trace the origins of individual diamonds, hindering efforts to ensure ethical sourcing.

In contrast, moissanite production takes place in laboratories where the entire process is carefully controlled. This eliminates the social and environmental issues commonly associated with diamond mining. Lab-grown moissanite avoids damaging habitats and ecosystems, and it significantly reduces the carbon footprint compared to diamond mining and extraction.

If sustainability is a priority for you, choosing moissanite offers a more eco-friendly alternative to traditional diamond engagement rings. By opting for lab-grown moissanite, you can enjoy the beauty and durability of a gemstone without contributing to the harmful impacts of diamond mining.

Advantages of Moissanite Sustainability:

  1. Eliminates environmental damage caused by diamond mining.
  2. Avoids unethical labor practices associated with the diamond industry.
  3. Contributes to reducing carbon emissions and overall environmental impact.
  4. Offers full transparency in the supply chain, ensuring ethical sourcing.

Disadvantages of Diamond Sustainability:

  1. Potential for environmental degradation due to mining activities.
  2. Concerns regarding labor practices and human rights violations in certain mining regions.
  3. Limited transparency in the sourcing and supply chain of individual diamonds.
  4. Higher carbon footprint compared to lab-grown moissanite.


“As a consumer conscious of sustainability, I chose moissanite for my engagement ring. Not only is it a beautiful and affordable alternative to diamonds, but it also aligns with my values. I feel good knowing that my ring doesn’t contribute to the negative impacts of diamond mining.” – Sarah Thompson
