It's one of the first questions people ask when they hear about lab-grown diamonds: 'But are they real diamonds?'
The short answer is yes — but the longer answer is more interesting, and worth understanding before you make any diamond purchase in the Philippines.
Here's a clear breakdown of what lab-grown and mined diamonds share, where they differ, and what that actually means for you as a buyer.
What They Have in Common (And It's a Lot)
The same chemical composition. Both lab-grown and mined diamonds are made of carbon atoms arranged in a crystal structure called the diamond cubic lattice. That structure is what gives diamonds their extraordinary hardness, their unique way of bending light, and their characteristic fire. Whether the diamond was formed underground over millions of years or grown in a laboratory over a few weeks, the atoms are arranged exactly the same way.
The same physical properties. Diamond is the hardest natural material on Earth, scoring 10 on the Mohs scale. Lab-grown diamonds are just as hard. They have the same refractive index, the same thermal conductivity, and the same density as mined diamonds. There's no physical test you can do at home — or with a standard jeweler's loupe — that will tell them apart.
The same visual appearance. A trained gemologist cannot distinguish a lab-grown diamond from a mined one by looking at it. Even expert diamond graders cannot tell the difference with the naked eye. The sparkle, the fire, the way light moves through the stone — it's the same.
The same grading system. Lab-grown diamonds are graded by the same international laboratories — GIA (Gemological Institute of America) and IGI (International Gemological Institute) — using the same 4Cs framework: Cut, Color, Clarity, and Carat. A certified lab-grown diamond from Love & Diamonds carries a grading report that works exactly like a mined diamond certificate.
Where They Differ
Origin. Mined diamonds form deep in the Earth's mantle under extreme heat and pressure over millions of years, then reach the surface through volcanic eruptions. Lab-grown diamonds are created in controlled laboratory conditions that replicate those same temperature and pressure conditions — but in weeks rather than millions of years.
There are two main production methods: HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition). Both produce real diamonds. The method affects some characteristics of the stone, which trained graders can detect using specialized equipment — but not with the naked eye or a standard loupe.
Price. This is the most significant practical difference for buyers. Lab-grown diamonds cost 50–70% less than mined diamonds of comparable quality. The price gap comes from the supply chain: growing diamonds in a controlled environment is fundamentally less resource-intensive than mining them from the earth. The lower cost does not reflect lower quality.
Traceability. Mined diamonds have complex, often opaque supply chains. Lab-grown diamonds are produced in known facilities with a clearer record of origin. For buyers who care about where things come from — and more people do, especially younger buyers — this is a meaningful distinction.
Resale value. Mined diamonds have historically held some resale value on the secondary market, though often less than buyers expect. Lab-grown diamonds currently have a lower resale value. If you're buying a diamond primarily as a financial investment, this is worth factoring in. If you're buying it to wear and enjoy for years — which is most people — this difference is far less relevant.
What This Means When You're Buying
If you want a real diamond: Lab-grown diamonds are real diamonds. The question 'are they real?' has a clear answer — yes. What most people are really asking is whether they look, feel, and perform like diamonds. They do.
If you want the best quality for your budget: Lab-grown diamonds give you significantly more for your money. The same budget that gets you a 0.5-carat mined diamond might get you a 1-carat lab-grown diamond of equal or better quality. That's a difference you can see with your eyes.
If origin and traceability matter to you: Lab-grown diamonds are the more transparent option. You know they weren't mined — which removes several categories of concern around sourcing and supply chains.
If resale value is your priority: Mined diamonds are the stronger choice for buyers treating diamonds as an asset. The traditional resale market has historically favored mined stones.
For most buyers in the Philippines: Lab-grown diamonds offer something genuinely valuable — a real, certified diamond at a price that makes it actually accessible, from a brand that shows you exactly what you're getting before you commit.
One More Thing: The Certificate
Every lab-grown diamond at Love & Diamonds comes with a GIA or IGI grading report. When you receive your certificate, you'll see the 4Cs grades, the diamond's unique report number (verifiable online), confirmation that it is a lab-grown diamond, and a diagram showing the location and nature of any inclusions.
This certificate is your guarantee. It travels with the diamond for its entire life. And it's exactly the same certificate format used for mined diamonds — because the standards are exactly the same.
The Bottom Line
Lab-grown and mined diamonds are made of the same material. They're graded the same way. They look the same, feel the same, and perform the same. The differences — origin, price, traceability, and resale value — are real, but they're also clear enough that you can make an informed decision based on what matters most to you.
At Love & Diamonds, every diamond comes certified. You see the grades before you buy. No surprises — just a clear picture of what you're getting and what it costs.
