Moissanite vs diamond, they are two different gemstones that have some similarities but also some important differences:

  1. Chemical Composition: Moissanite is composed of silicon carbide (SiC), while diamond is composed of carbon (C). This means that they have different chemical and physical properties.
  2. Hardness: Diamond is the hardest natural substance on earth, with a rating of 10 on the Mohs scale of mineral hardness. Moissanite is also a very hard gemstone, with a rating of 9.25 on the Mohs scale. This means that both gems are durable and resistant to scratches and chips, but diamond is slightly harder.
  3. Brilliance: Moissanite has a higher refractive index than diamond, meaning it has more fire and brilliance. This can make it appear more sparkly and colourful than diamond, especially in certain lighting conditions.
  4. Colour: Diamonds are valued for their lack of colour, with the most valuable diamonds being completely colourless. Moissanite, on the other hand, has a slight yellow or green tint, although some moissanite stones are now available in near-colourless grades.
  5. Rarity: Diamonds are rare and valuable, with the most desirable diamonds being those that are large, colourless, and free of inclusions. Moissanite, on the other hand, is a lab-grown gemstone that is relatively abundant and less expensive than diamond.
  6. Origins: Diamonds are formed deep in the earth over millions of years, while moissanite is typically grown in a laboratory using a process called chemical vapour deposition.

One more thing to consider is that because moissanite has a higher refractive index than diamond, it can sometimes appear too “sparkly” or “disco ball-like” to some people. This is a matter of personal preference, but some people may prefer the more subtle sparkle of diamond.

Another difference between moissanite and diamond is that moissanite has a different pattern of light dispersion than diamond. While diamond exhibits a rainbow of colours, moissanite has a more complex pattern of light dispersion that some people find more interesting or unique.

When choosing between moissanite and diamond, it’s important to consider your personal preferences and what factors are most important to you, such as price, durability, rarity, brilliance, and colour. Ultimately, the choice comes down to what you feel is the best fit for you and your partner’s needs and preferences.

It’s also important to note that while moissanite is less expensive than diamond, the price can vary depending on the size, quality, and cut of the stone. Moissanite is typically less expensive than diamonds of similar size and quality, but it’s not necessarily a “cheap” alternative to diamond. It can still be a meaningful and valuable gemstone for an engagement ring, regardless of the price.

Another thing to consider is that while moissanite is a relatively new gemstone, it has been gaining popularity in recent years and is becoming more widely recognized as a viable alternative to diamond. This means that it may be easier to find moissanite engagement rings and other jewellery options than it was in the past.

Ultimately, the choice between moissanite and diamond comes down to personal preference, values, and budget. Both gemstones can be beautiful and meaningful options for an engagement ring, and it’s important to choose the one that feels right for you and your partner.

Overall, while moissanite and diamond share some similarities, they are two distinct gemstones with different properties, values, and origins. When choosing between a moissanite and diamond, it’s important to consider what factors are most important to you, such as price, durability, rarity, and appearance.
