Lab-Grown Diamonds vs Natural Diamonds: What's the Difference?
Are Lab-Grown Diamonds "Real" Diamonds?
Yes. A lab-grown diamond has the exact same chemical composition, crystal structure, hardness and optical brilliance as a natural diamond. The only difference between lab-grown diamonds and natural diamonds is where and how they formed — natural diamonds crystallise in the earth over a billion years or more, while lab-grown diamonds are grown in a matter of weeks using either the HPHT (High Pressure, High Temperature) or CVD (Chemical Vapour Deposition) method. Both are certified, graded on the same 4Cs scale, and equally durable for everyday wear.
Lab-Grown vs Natural Diamonds: Key Differences
- Origin: Natural diamonds are mined from the earth; lab-grown diamonds are grown in a controlled facility.
- Price: Lab-grown diamonds typically cost significantly less than natural diamonds of the same carat, cut, colour and clarity — which is why many buyers choose a larger or higher-grade lab-grown stone for the same budget.
- Appearance: Under normal viewing conditions, a well-cut lab-grown diamond and a natural diamond are visually indistinguishable to the naked eye.
- Identification: Both natural and lab-grown diamonds require specialised gemological equipment to tell apart — this is precisely why certification matters.
- Environmental impact: Lab-grown diamonds avoid the large-scale earth excavation associated with diamond mining.
Does a Lab-Grown Diamond Hold Its Value?
Lab-grown and natural diamonds are priced on different markets, and lab-grown diamond prices have followed their own trajectory as production has scaled. If long-term resale value matters to you, it's worth discussing this directly with your jeweller before you buy — value considerations differ from stone to stone and shouldn't be assumed either way.
Which Should You Choose?
There's no universally "better" choice — it comes down to what matters most to you. If you want the maximum size and clarity for your budget, a lab-grown diamond often makes sense. If provenance and rarity from the earth matter most, a natural diamond may be the right fit. Every diamond at Vimora — lab-grown or natural — is certified and graded to the same standard, so you can compare confidently.
