Natural (or mined) vs lab-grown diamonds is one of the most talked-about topics in jewellery right now. While they appear identical at first glance, their origin, value, and creation process tell two very different stories.
As lab-grown diamonds become more widely available, so too does the conversation around them, sometimes clear, sometimes confusing. At Nina's Jewellery, we believe in keeping things simple, honest, and beautifully transparent so you can make a choice that feels right for you.
Let’s take a closer look.
Formation: Nature vs innovation
Natural diamonds are formed deep within the Earth over billions of years under intense heat and pressure. Brought to the surface through ancient volcanic activity, each stone is a rare fragment of geological history shaped entirely by nature and time.
Lab-grown diamonds, on the other hand, are created using advanced technology that replicates these natural conditions.
At Nina’s, our lab-grown diamonds are created using the Chemical Vapour Deposition method. A diamond seed is placed in a controlled chamber filled with carbon-rich gas. Over time, carbon atoms bond layer by layer, gradually forming a diamond with the same physical, chemical, and optical structure as those formed in nature.
Different origin. Same diamond.
Appearance: Can you tell the difference?
In short, no.
Lab-grown and natural diamonds are chemically and optically identical. Even trained gemmologists cannot distinguish between them without specialised equipment.
Both can feature unique inclusions, giving each diamond its own character and fingerprint. When it comes to brilliance, fire, and durability, there is no visible difference to the naked eye.
Our in-house GIA qualified Gemmologist, Deb Turner advises: "As a gemmologist with experience in both natural and lab-grown stones, I can confirm that visual identification without equipment is impossible. While I can readily distinguish diamond simulants like Cubic Zirconia from natural diamonds, lab-grown stones require specialised instruments. Therefore, I depend on certifications and industry expertise when sourcing diamonds.
Value: Cost, rarity, and perspective
One of the most notable differences is price. Lab-grown diamonds are typically cheaper (approx 80% cheaper) often allowing clients to choose a larger or higher-graded stone within the same budget.
Natural diamonds, formed over billions of years, are finite and rare. This rarity has historically contributed to stronger long-term resale demand.
Lab-grown diamonds, while offering incredible visual value, do not currently hold the same resale performance due to increasing supply and evolving market conditions.
Neither is right or wrong. It simply comes down to what matters most to you, whether that is size, rarity, budget, or long-term value.
“Ultimately, the value of luxury items is influenced by many factors, including rarity, provenance and market demand. While natural diamonds have historically maintained stronger resale value, lab-grown diamonds offer an exciting opportunity for customers seeking exceptional size and quality at a more accessible price point.” - Deb Turner, GIA certified gemmologist.
Sustainability: A more nuanced conversation
It is a common misconception that lab-grown diamonds are more environmentally friendly. This is not exactly the case. Both natural and lab-grown diamonds have environmental impacts, but they differ in type and scale.
Natural diamond mining can involve land and habitat disruption as well as water usage. However, modern practices continue to evolve with a stronger focus on responsible sourcing, land rehabilitation, and reduced environmental impact across the supply chain.
Lab-grown diamonds, however, require significant energy input during production. Their carbon footprint is generally larger, as it is influenced by the energy source each lab uses during the growth process, which is typically heavily reliant on fossil fuels.
At Nina’s, we work only with trusted suppliers who prioritise ethical work practices, transparency, and responsible sourcing across both natural and lab-grown diamonds.
Which diamond is right for you?
Both natural and lab-grown diamonds bring something meaningful to the table.
Natural diamonds carry the romance of time, rarity, and geological wonder.
Lab-grown diamonds reflect modern innovation, accessibility, and versatility.
Neither replaces the other. They simply offer different ways to express your own personal sentiment and preferences.
At Nina’s, we believe a diamond is never just a diamond. It represents love, memory, celebration, and connection. Whether natural or lab-grown, every diamond we source is selected with exceptional quality and authenticity at the heart of what we do.
If you are still exploring, we are here to help you find the diamond that feels like you. Visit us in Dunsborough or speak with our team for honest, considered guidance.
Why do Nina’s now offer lab-grown diamonds?
Quite simply, because you asked for them!
Some of our clients began seeking larger diamonds at a more accessible price point, without compromising on beauty or brilliance. We listened.
Today, we are proud to offer both natural and lab-grown diamonds because we believe jewellery should reflect individual priorities, style, and story.
Our view is simple. There is no better diamond, only the one that is better for you.
“Both options have their place, and the most important thing is understanding what matters most to the individual choosing the stone." Deb Turner, Gemmologist
FAQs
Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds are real diamonds. They share the same chemical, physical, and optical properties as natural diamonds. The key difference is origin. Lab-grown diamonds are created in a controlled environment over weeks, while natural diamonds form deep within the Earth over billions of years.
Can you tell the difference between lab-grown and natural diamonds?
Not with the naked eye. They look identical in terms of brilliance, fire, and structure. Even trained gemmologists require specialised equipment to identify the origin of a diamond. At Nina’s, all diamonds are assessed and certified to ensure full transparency.
Do lab-grown diamonds hold their value?
Lab-grown diamonds generally have a lower resale demand compared to natural diamonds. This is largely due to increasing supply and more accessible production methods. Natural diamonds have historically maintained stronger long-term value due to their rarity and finite supply. However, resale value can vary depending on size, quality, and market conditions.
Are lab-grown diamonds more sustainable than natural diamonds?
The environmental impact of both lab-grown and natural diamonds is complex and depends on how they are produced.
Lab-grown diamonds require significant energy, and their footprint depends heavily on the energy source used during production. Natural diamond mining can involve land disturbance and water usage, although modern mining practices have improved significantly with rehabilitation and ethical sourcing standards.
Rather than one being universally “more sustainable,” both come with different environmental considerations.
Why are natural diamonds more expensive?
Natural diamonds are formed over billions of years under extreme conditions, making them finite and rare. Their price reflects this scarcity, along with global demand, grading quality, and craftsmanship. Each natural diamond is unique, which also contributes to its value.
What is the environmental impact of natural diamonds?
Natural diamond mining can impact land and ecosystems during extraction. However, many modern operations are highly regulated and include environmental rehabilitation programs after mining ends. Some regions, such as the Argyle Mine in Australia, have also implemented long-term land restoration initiatives following closure.
Which is better, lab-grown or natural diamonds?
Neither is better overall. The right choice depends on personal priorities.
Lab-grown diamonds may appeal to those seeking a larger size or higher specification within a set budget. Natural diamonds may appeal to those who value rarity, geological origin, and long-term collectability. Both are genuine diamonds and both have a place in modern jewellery.
Can I buy a lab-grown diamond from Nina’s?
Yes. While Nina’s specialises in natural diamonds, we also source lab-grown diamonds. We offer both options so you can choose what aligns best with your style, budget, and values. Our focus is always on quality, craftsmanship, and helping you find the right stone.
Are lab-grown diamonds considered luxury items?
Lab-grown diamonds are considered fine jewellery and are widely used in modern design. Luxury is defined differently by different people. For some, it is rarity and provenance. For others, it is size, design, and personal meaning. Natural diamonds have traditionally been associated with heritage and rarity, while lab-grown diamonds reflect innovation and accessibility. Both can exist within the luxury jewellery space depending on context and intention.
