As a supplier of round shape moissanite, I'm often asked about the advantages of this beautiful gemstone. However, it's also important to have an open and honest discussion about its potential disadvantages. In this blog post, I'll delve into some of the drawbacks associated with round shape moissanite, so that you can make an informed decision when considering this gem for your jewelry.

1. Perceived Value in the Market

One of the main disadvantages of round shape moissanite is its perceived value in the market. Despite its many excellent qualities, moissanite is often compared to diamonds, which have a long - standing and deeply ingrained cultural and economic value. Diamonds have been marketed as symbols of luxury, commitment, and status for decades. As a result, many consumers still associate high value primarily with diamonds.

When it comes to resale, diamonds generally hold their value better than moissanite. The diamond market is well - established, with clear grading systems and a large network of buyers and sellers. In contrast, the moissanite resale market is relatively small. If you were to sell a piece of jewelry with a round shape moissanite in the future, you might find it more challenging to get a high return on your investment compared to a diamond of similar size and quality.

2. Heat Sensitivity

Another drawback of round shape moissanite is its heat sensitivity. Moissanite has a different thermal conductivity compared to diamonds. While diamonds are excellent conductors of heat, moissanite is not as efficient in this regard.

When exposed to high temperatures, moissanite can be damaged. For example, during jewelry repair or setting processes that involve soldering or welding, the heat can cause the moissanite to crack or change its optical properties. Jewelers need to be extremely careful when working with moissanite to avoid overheating it. This limitation can make the manufacturing and repair of moissanite jewelry more complex and potentially more expensive, as specialized techniques may be required to ensure the gemstone's integrity.

3. Hardness and Durability Considerations

Although moissanite is a relatively hard gemstone, with a hardness of around 9.25 on the Mohs scale (compared to 10 for diamonds), it is still not as hard as diamonds. This means that over time, moissanite may be more prone to scratching and chipping, especially in high - wear situations.

For instance, if you wear a round shape moissanite ring on your hand daily and it comes into contact with hard surfaces frequently, the edges of the moissanite may start to show signs of wear. In comparison, a diamond ring would be more resistant to such damage. This reduced durability can affect the long - term appearance of the jewelry, and you may need to take extra care when wearing moissanite pieces to avoid unnecessary damage.

4. Color and Clarity Perception

In terms of color and clarity, moissanite has its own characteristics that may not be as appealing to some consumers compared to diamonds. While moissanite can come in a range of colors, the most common ones are near - colorless to slightly yellowish. Some people prefer the pure, icy white color that high - quality diamonds can offer.

Regarding clarity, moissanite may have inclusions or internal flaws that are more visible to the naked eye compared to diamonds of similar price points. These inclusions can affect the overall sparkle and beauty of the round shape moissanite, making it less desirable for those who are looking for a gemstone with perfect clarity.

5. Market Misconceptions

There are also many market misconceptions surrounding moissanite. Some consumers may still believe that moissanite is an imitation or a fake diamond. This perception can be a barrier for those who are considering moissanite for its own merits.

Despite being a natural - occurring mineral (although most moissanite used in jewelry is lab - created), the association with "diamond substitutes" can make it difficult for moissanite to gain full acceptance in the luxury jewelry market. People may be hesitant to purchase a round shape moissanite piece because they worry about what others might think or because they want a gemstone with a more "prestigious" reputation.

6. Limited Customization Options

Compared to diamonds, round shape moissanite may offer more limited customization options. Since the diamond market is so large, there are a wide variety of cuts, settings, and styles available. Jewelers are also more experienced in working with diamonds, and they may have more creative designs specifically tailored for diamond jewelry.

With moissanite, the range of available settings and custom designs may be more restricted. This can be a disadvantage for consumers who are looking for a unique and personalized piece of jewelry. For example, if you have a very specific design in mind for a round shape moissanite ring, you may find it harder to find a jeweler who can execute it as precisely as you would like.

7. Light Dispersion and Fire

While moissanite is known for its high light dispersion, which gives it a lot of "fire" or colorful flashes of light, this can sometimes be a drawback. The intense fire of moissanite can be so pronounced that it may appear a bit too "flashy" or artificial to some people.

In contrast, diamonds have a more subtle and elegant play of light. The excessive fire of moissanite may not be to everyone's taste, especially those who prefer a more understated and classic look in their jewelry.

Despite these disadvantages, it's important to note that round shape moissanite also has many advantages. It is a beautiful, affordable, and ethical alternative to diamonds.
