Laboratory Grown Diamonds: Myths vs Facts – What You Need to Know

Laboratory grown diamonds have become a popular choice for engagement rings and fine jewellery, but misconceptions still surround them. Many shoppers wonder if they are 'real' diamonds, if they hold their value, or if they are truly eco-friendly. In this article, we’ll debunk common myths and present the facts, so you can make an informed decision when choosing a diamond that honours your story.

Whether you’re considering a lab diamond for its ethical appeal or its affordability, understanding the truth is essential. Let’s explore the most persistent myths and uncover the reality behind laboratory grown diamonds.

Myth 1: Lab Grown Diamonds Are Fake or Simulants

One of the most widespread myths is that laboratory grown diamonds are fake, like cubic zirconia or moissanite. The fact is, lab grown diamonds are chemically, physically, and optically identical to mined diamonds. They are made of pure carbon crystallised in the same cubic structure. The only difference is their origin: one is grown in a lab, the other formed deep within the Earth. Both are graded using the same 4Cs (cut, colour, clarity, carat) and require a trained gemologist with specialised equipment to tell them apart.

At Natalie Marie Jewellery, we offer stunning lab grown diamond pieces like the Átlas Marquise Signet | Laboratory Grown Diamond, which showcases the brilliance and beauty of a genuine diamond. When you choose a lab diamond, you are choosing a real diamond—just grown in a controlled environment.

Myth 2: Lab Diamonds Are Flawless and Perfect

Some believe that because diamonds are grown in a lab, they are all flawless. In reality, lab grown diamonds have inclusions and variations, just like natural diamonds. They are graded on the same clarity scale, from Flawless to Included. While labs can control conditions to reduce impurities, not every stone is perfect. This actually benefits buyers, as you can find a lab diamond with minor inclusions at a more accessible price point without sacrificing beauty.

For example, the Patera Ring | Champagne & White Diamonds features a unique combination of natural and lab grown diamonds, demonstrating that both types can coexist in a single design. The key is to choose a diamond that speaks to you, whether it’s eye-clean or has a distinct character.

Myth 3: Lab Grown Diamonds Have No Resale Value

It’s often said that lab diamonds are worthless on the resale market. While it’s true that lab diamonds generally have a lower resale value than natural diamonds (similar to how cars depreciate), they are not worthless. The resale market for lab diamonds is growing as consumer acceptance increases. Moreover, many buyers today prioritise the initial cost savings and ethical benefits over future resale. For most jewellery purchases, the sentimental value far outweighs any potential resale.

Think of your diamond as a symbol of your story, not an investment asset. The Thalia Crown Ring I | Natural Diamonds is a timeless piece that can be treasured for generations. Whether you choose a lab or natural diamond, the value lies in the memories it represents.

• Tip: If resale value is important to you, consider a natural diamond. But if you want the best value for your budget and ethical peace of mind, a lab diamond is an excellent choice.

Myth 4: Lab Diamonds Are Not Eco-Friendly

Some argue that the energy required to grow diamonds in a lab makes them less eco-friendly than mined diamonds. The truth is more nuanced. Lab grown diamonds have a significantly lower environmental impact in terms of land disruption, water usage, and carbon emissions when produced using renewable energy. Many labs are now powered by solar or wind energy. In contrast, traditional mining can cause deforestation, soil erosion, and water pollution. While no diamond is entirely impact-free, lab diamonds offer a more sustainable option for environmentally conscious consumers.

At Natalie Marie Jewellery, we carefully source both natural and lab grown diamonds to offer choices that align with your values. Our Sana Charm Necklace | Jasper features natural gemstones, but we also carry lab diamond pieces for those seeking a lighter footprint.

Myth 5: Lab Diamonds Are Cheaper Because They Are Inferior

The lower price of lab diamonds often leads to the assumption that they are of lower quality. In fact, lab diamonds cost 30-50% less than comparable natural diamonds because the supply chain is shorter and production is more efficient. The quality is identical—same hardness, same sparkle, same durability. The price difference reflects the cost of mining and the rarity of natural diamonds, not a difference in quality. You can get a larger or higher-clarity lab diamond for the same budget as a smaller natural stone.

This makes lab diamonds an attractive option for those who want a statement piece without compromising on size or quality. For instance, a lab grown diamond engagement ring can offer a larger centre stone at a fraction of the cost of a mined diamond.

Understanding the facts about laboratory grown diamonds empowers you to make a choice that aligns with your values, budget, and style. Whether you’re drawn to the ethical advantages, the affordability, or simply the beauty of a real diamond grown in a lab, there is a perfect piece waiting for you.
