moissanite vs diamond engagement rings

For the perfect engagement ring, it is often a matter of one very simple decision: moissanite vs. diamond. As more couples prioritize sustainability and budget-friendly options, moissanite has become quite popular. But how does it compare to the timeless appeal of a diamond?

We’ll help you decide, if you’re considering your options. This guide highlights the main differences between moissanite and diamond engagement rings — from looks to price, durability, and ethical concerns — so you can make the best choice.

What is Moissanite?

Moissanite is a gemstone first discovered in 1893 by Nobel prize-winning chemist Henri Moissan. Initially mistaken for diamonds, moissanite is a naturally occurring silicon carbide. However, the moissanite used in jewelry today is lab-created, ensuring consistent quality and sparing the environment from mining.

A Unique Gem in Its Own Right

Although moissanite resembles a diamond, it stands out with its exceptional brilliance and fire. Its rainbow-like sparkle, caused by its high refractive index, makes it a dazzling centerpiece for any engagement ring.

How Do Moissanite and Diamonds Compare?

Here is where the decision becomes tricky. While they might look similar at first glance, moissanite and diamonds differ significantly in terms of composition, appearance, cost, and overall value.

1. Appearance

Take the time to compare moissanite to diamonds and the first thing you’ll notice is they catch the light differently.

  • Moissanite (2.65–2.69) has a higher refractive index than diamonds (2.42). This is what gives moissanite its trademark “rainbow sparkle” or fire. A few couples adore the worthy flashes, while others may find this style a little bold in the face of the traditional, mute brilliance of a diamond.
  • Diamonds refract light more subtly, creating a warm, sophisticated sparkle.

Tip: Want a classic and elegant look? Opt for a diamond. If you appreciate extra sparkle and aren’t worried about standing out, moissanite may be just your style.

2. Durability

Durability is a key factor in rings meant to last a lifetime.

  • Diamonds are the hardest known natural substance, scoring a 10 on the Mohs scale of hardness. They are highly resistant to scratches and wear, making them ideal for daily wear.
  • Moissanite is also incredibly durable, scoring a 9.25 on the Mohs scale. While slightly less hard than diamonds, it’s still tough enough for everyday use and more scratch-resistant than most other gemstones.

3. Cost

When it comes to pricing, moissanite is the clear winner.

  • Moissanite costs a fraction of what diamonds do. For example, a 1-carat moissanite engagement ring typically ranges from $300 to $600, depending on the cut and quality.
  • Diamonds, on the other hand, cost between $1,500 and $20,000+ for a 1-carat stone, depending on the cut, clarity, color, and weight.

Why the Difference?

Diamonds’ higher price is partly due to their rarity (even lab-grown ones require advanced technology to produce) and their historical association with luxury. Moissanite, as a lab-created gem, is more affordable to produce and buy.

4. Ethics and Sustainability

Ethical and environmental considerations play a significant role in today’s jewelry market.

  • Moissanite is inherently more sustainable and ethical. Because it’s lab-created, it avoids the environmental destruction, conflicts, and ethical dilemmas often associated with diamond mining.
  • Diamonds can be either mined or lab-grown. While lab-grown diamonds are a more ethical option than mined ones, they still tend to be pricier than moissanite.

5. Resale Value

Diamonds are superior if resale or investment value is important to you.

Because diamonds have a timeless status and are part of a tradition, they usually hold some value and can be sold (although often at less than the original purchase price).

As a relatively new gemstone, moissanite has no considerable resale value at all. On the other hand, this can be more than offset for cash-conscious buyers by its lower upfront cost.
