Have you ever thought about why people talk so much about moissanite vs diamond? Both gems are shiny, beautiful, and popular for rings and jewellery. People want to know which one is better for them. Moissanite is getting more popular as a diamond alternative. But are Moissanite wedding rings considered tacky to wear in the UK? It’s not just about the sparkle. It’s about what fits your lifestyle and style while saving you money compared to a diamond.
That’s why it’s helpful to understand what makes moissanite and diamonds different. Whether you're shopping for an engagement ring or just love sparkly things, knowing the basics can help you make the right choice for your style and budget.
What Is Moissanite?

Moissanite is rare and is made from silicon carbide, so most of the moissanite used in jewellery today is lab-created. These lab-made gems are just as beautiful and much better for the environment.
Moissanite is loved for its colourful sparkle, like a tiny rainbow on your finger, and it's strong enough to wear every day without worry. That’s why it’s become popular for all kinds of moissanite jewellery, from rings to earrings.
What Is a Diamond?

Diamonds are the classic and iconic gemstones that have been admired for generations. They are well-known for their unmatched brilliance and timeless appeal. They form deep inside the Earth over millions of years, made of pure carbon tightly packed together. Diamonds are the hardest natural material on Earth, so they last forever and resist scratches so well. For centuries, their bright, white sparkle has made them the go-to symbol of love and commitment.
Whether in engagement rings or royal crowns, diamonds carry a timeless elegance and tradition that few gems can match.

Which Gemstone Fits Your Perfection? Moissanite vs. Diamonds
Moissanite is famous for its intense fire and rainbow sparkle, reflecting light in a colourful, almost disco-ball-like way. This makes moissanite sparkle with a lively, eye-catching glow that many find irresistible.
On the other hand, diamonds offer a classic brilliance with more white light reflection for a subtle, elegant shine. Franc Laurent offers stunning moissanite jewellery that captures this unique brilliance, from rings to pendants. The size and cut of both stones play a big role in how much they sparkle, making both diamonds and moissanite stunning choices depending on your style.
Colour and Clarity Colour
Moissanite is usually near-colourless, giving it a clean and bright look. However, it can sometimes show a soft yellow or greenish tint under certain lights. Diamonds offer a broader range of colours, from completely colourless to light brown or yellow shades, and even rare fancy colours like blue and pink. Diamonds can offer incredible options if you want a pure, icy white stone. Regarding clarity, moissanite often appears ahead because it is usually eye-clean, meaning you won’t spot any blemishes without a magnifying glass.
Diamonds, however, can have tiny inclusions, like small natural birthmarks within the stone. The difference between diamond and moissanite in clarity is not always easy to notice with the naked eye, so trust what looks beautiful, not just what’s written on a certificate.
Hardness and Durability
Hardness determines how well your stone will survive life’s little accidents. Diamonds are the hardest natural material known to man, scoring a perfect 10 on the Mohs scale. They are tough enough to handle dishwashing, rock climbing, or even wrestling with your toddler without a scratch. While slightly softer, moissanite still ranks very high with a 9.25 on the Mohs scale. Unless you plan on arm-wrestling a bear, moissanite is durable for everyday life. Both stones are ideal for rings, earrings, or necklaces worn daily.
Diamonds are a touch more scratch-resistant, but in real-world use, the difference is very minor. Neither stone will cry if you bump it against a door or forget to take off your ring while playing fetch with your dog. Hardness might sound technical, but it keeps your jewellery looking fabulous for years.
Price and Value
Let’s be honest — sparkle is wonderful, but price matters too. Moissanite offers a huge advantage here because it costs significantly less than diamonds of similar size and appearance. You can get a larger, dazzling moissanite stone and still have enough left over for a nice dinner (or three). Diamonds, especially high-quality ones, can be extremely expensive, often costing two or three times more than a moissanite of the same size. Moissanite is an excellent choice if you want maximum sparkle for your budget.
However, resale value is where diamonds pull ahead. Over time, diamonds tend to retain some of their value, while moissanite does not have the same strong resale market. It's a bit like buying a brand-new video game versus a vintage collector’s item — both are fun, but one holds its value longer. Consider what matters most: dazzling today, or investment potential tomorrow.
Ethical and Environmental Considerations
You're in luck if you want to simultaneously sparkle and save the planet. It is lab-grown, meaning it’s created in a controlled environment without mining. It has a much lower environmental impact and is fully traceable, so you know exactly where it came from. Diamonds, meanwhile, can either be mined or lab-grown, but traditional mining can cause significant environmental and ethical concerns. Issues such as unsafe working conditions, land disruption, and ethical sourcing challenges have long been linked to diamond mining.
If sustainability and ethics are important, moissanite often stands out as the greener and more guilt-free choice. When you consider the moissanite and diamond comparison from an environmental point of view, it’s clear that moissanite shines even brighter. After all, nothing looks better than sparkle you can feel proud to wear.
Grading and Certification
When shopping for a gemstone, knowing what you’re getting is important. Diamonds are graded using the famous "4Cs" — cut, colour, clarity, and carat weight — giving buyers a detailed report card for each stone. Moissanite is graded mainly on cut, colour, and clarity, and you’ll often see terms like Premium or Super Premium to describe the quality levels.
Carat weight is less emphasised with moissanite because it’s slightly lighter than diamond for the same size. No matter which stone you pick, certification helps you shop smarter and protects you from getting fooled by something that just looks good under store lights. A properly graded stone sparkles better and holds up better over time. After all, choosing your forever sparkle should be more than just crossing your fingers and hoping for the best — it's about knowing you picked a true gem.
Tips on Selecting the Right Stone
Here are some of the most essential tips to choose the right stone that perfectly suits your personality, which are defined below step by step:

Know Your Budget First
Before picking a stone, consider how much money you want to spend. Stones can be pricey or cheap. Setting a budget helps you avoid surprises. Remember, a beautiful stone doesn’t always mean a big price tag. You can find shiny gems that look great and fit your wallet. So, plan your budget well and stick to it.
Match Your Style and Values
Your stone should match your style. Are you classic, bold, or simple? Also, think about your values. Some stones are mined in ways that hurt the earth. Others are made in labs and are eco-friendly. Choosing a stone that fits your personality and beliefs makes it special.
Think About Sparkle and Colour
Do you want a stone that shines super bright or one with a soft glow? Some stones sparkle like a disco ball, while others have gentle colours. Colour matters too- some rocks come in many shades. Decide if you want clear, white, or colourful stones. Your choice will make your jewellery stand out or blend in. Pick the sparkle and colour that makes you smile whenever you see it.
Check Durability for Everyday Wear
If you wear your jewellery daily, the stone must be tough. Some stones scratch or chip easily. Others can handle bumps and drops. Think about how active you are. Pick a strong stone if you play sports or work with your hands. This way, your jewellery stays pretty for a long time. Tough stones are like superheroes-they protect your style.
