Moissanite vs. Diamond: Differences in Brilliance, Hardness, and Price
A ring shouldn't look like a compromise. Moissanite combines exceptional brilliance, excellent suitability for everyday wear, and a price that leaves room for your future together.
Short answer
A moissanite engagement ring is an excellent choice if you’re looking for intense brilliance, high durability for everyday wear, and significantly better value for the price. When comparing moissanite to diamond, moissanite comes out on top in terms of apparent size, vibrant fire, and value for the price.
More passion. More presence. Less stress over the budget.
Many couples start by looking for a diamond because they believe that only a diamond gives an engagement ring true meaning. But the modern question is no longer simply, “Is it a diamond?” The better question is, “Which stone will give me the most beautiful look, the greatest everyday durability, and the best sense of satisfaction with my decision?”
Moissanite became an attractive option precisely because of this kind of decision. It is extremely hard, exceptionally brilliant, and created in a lab under controlled conditions. This means you get a ring that looks clear, large, and high-quality without the price skyrocketing out of proportion.

Important: Moissanite is not a substitute for diamond. It is a distinct choice for couples who value brilliance, everyday wearability, and value for money more highly than a stone’s rarity.

Frequently Asked Questions About Moissanite Engagement Rings
Is a moissanite engagement ring a good choice?
Yes. A moissanite engagement ring is a great choice if you're looking for intense brilliance, high durability for everyday wear, and excellent value for the price. It looks luxurious, but is much more affordable than many comparable diamond options.
What is the difference between moissanite and diamond?
Diamond is pure carbon and has a hardness of 10 on the Mohs scale. Moissanite is silicon carbide, has a hardness of about 9.25, and has a higher refractive index. That is why moissanite often sparkles more vividly and with more colour.
Does moissanite look like a diamond?
At first glance, moissanite looks very similar to many people, but it has a stronger, more colourful fire. It is precisely this vibrant brilliance that leads many Velur customers to consciously choose moissanite.
Is moissanite durable enough for everyday wear?
Yes. Moissanite is very hard—about 9.25 on the Mohs scale—making it ideal for engagement rings that are worn every day. As with any high-quality ring, the setting should be checked regularly, and the ring should be removed during sports or when doing heavy work.
Why is moissanite less expensive than a diamond?
The price is less a function of rarity and more a result of controlled laboratory production. This allows a moissanite ring to appear larger and more luxurious without breaking the bank, as is often the case with many diamond options.
How much does a moissanite engagement ring cost at Velur?
Many Velur moissanite engagement rings start in the range of about 900 to 1,400 euros. The exact price depends on the stone, size, cut, gold option, and design.
