Moissanite is a popular alternative to diamond engagement rings due to its affordability, durability, and stunning appearance. However, like any gemstone, moissanite has its downsides. In this article, we’ll explore the downsides of moissanite, helping you make an informed decision when choosing the perfect engagement ring.

Not a Natural Gemstone

Moissanite is a lab-created gemstone, meaning it’s not a naturally occurring gemstone. While some people don’t mind wearing a lab-created stone, others prefer the authenticity and uniqueness of natural gemstones. If you’re looking for a naturally occurring gemstone, moissanite may not be the right choice for you.

Lower Resale Value

Unlike diamonds, moissanite has a lower resale value. This is because it’s a lab-created gemstone and doesn’t have the same rarity and prestige as diamonds. If you’re looking for a gemstone with high resale value, moissanite may not be the best choice.

Limited Availability

Moissanite is not as widely available as diamonds. While some jewelry stores carry moissanite, you may have to do some research to find a store that offers a wide selection. Additionally, if you want a custom moissanite ring, you may have to order it from a specialized jeweler, which can be time-consuming and more expensive.

Not as Hard as Diamonds

Moissanite is a durable gemstone, with a Mohs hardness rating of 9.25. However, it’s not as hard as diamonds, which have a Mohs hardness rating of 10. This means that moissanite is more prone to scratching than diamonds. While moissanite is still a durable gemstone, it may require more care and maintenance to keep it looking its best.

Can Look Artificial

Some people believe that moissanite has a “too perfect” look, making it look artificial. While this is subjective, some people prefer the natural imperfections and character of diamonds. Additionally, moissanite has a higher refractive index than diamonds, meaning it can create a “rainbow effect” that some people may not find appealing.


One potential downside of moissanite that some people may not consider is the environmental impact of lab-created gemstones. While moissanite is a more ethical choice than diamonds, which often come from conflict zones and may be associated with human rights abuses, the production of lab-created gemstones still has an environmental impact. The process of creating moissanite requires a significant amount of energy and resources, which can contribute to greenhouse gas emissions and other environmental issues. If sustainability is a priority for you, you may want to consider this when deciding whether or not to choose moissanite for your engagement ring.

From not being a natural gemstone to having a lower resale value and limited availability, it’s essential to consider these factors when choosing your engagement ring.
