Natural vs Lab Diamonds — What Nobody Is Telling You

The diamond industry has changed dramatically in the last five years. If you are considering a diamond purchase — whether for an engagement ring, a special gift, or a piece you will pass down one day — there is information you deserve to have before you decide.

We are not going to tell you what to buy. We source both natural and lab-grown diamonds for our clients and we will do the same for you. But after 20 years of manufacturing fine diamond jewellery in Bangkok, we believe every buyer should make their decision with the full picture in front of them.

The Lab Diamond Promise — And What Happened Next

When lab-grown diamonds entered the mainstream market, the proposition was compelling. A visually identical diamond — same hardness, same brilliance, same chemical composition — at a fraction of the price of natural. Smart marketing positioned lab diamonds as the intelligent, modern choice.

In 2020, a high quality 5 carat lab-grown diamond was priced at approximately $20,000. A comparable natural diamond at wholesale was around $160,000 — with retail prices reaching $200,000 to $300,000. The price difference was extraordinary and for many buyers, lab seemed like an obvious decision.

Today, that same 5 carat lab-grown diamond costs approximately $1,000.

That is not a typo. A stone that cost $20,000 four years ago now costs $1,000 — a drop of 95% in value.

We have a client who has watched this happen in real time. They purchased a lab diamond when it was $20,000. Then sourced another when the price dropped to $5,000. Then again at $1,000. Each time, the stone looked identical. Each time, the price was lower. This is not a criticism of that client — it is simply what happens when a product becomes a commodity. And that is exactly what lab diamonds have become.

Why Lab Diamond Prices Collapsed

Natural diamonds take billions of years to form under extreme heat and pressure deep within the earth. Supply is finite and extraction is complex.

Lab diamonds are grown in controlled environments in a matter of weeks. As the technology improved and more producers entered the market, supply increased rapidly. Basic economics took over. Prices fell — and they continue to fall.

There is no floor in sight for lab diamond prices. As production becomes more efficient and more widespread, the cost of growing a lab diamond will keep decreasing. This is good for manufacturers. It is not good for anyone who paid a premium for one expecting it to hold its value.

The Natural Diamond Opportunity Nobody Is Talking About

Here is what makes the current moment genuinely interesting for buyers.

Natural diamond prices have also softened in recent years. The wholesale price of a fine natural diamond today is meaningfully lower than it was at its peak. For buyers who always wanted a natural diamond but found the price out of reach, right now represents a real opportunity to own something exceptional at a price that would have been unthinkable a few years ago.

A natural diamond formed over billions of years. No two are identical. It carries a geological history that no machine can replicate. And unlike a lab stone, its supply cannot simply be scaled up to meet demand.

For a buyer who wants the look of a diamond at the lowest possible price point, lab makes complete sense. We will source it for you without hesitation.

But for a buyer who wants to wear something with genuine rarity — something that carries weight beyond its appearance — natural diamond at today's prices is worth serious consideration.

The Emotional Difference

This is the part that is hardest to quantify but easiest to feel.

There is a difference between wearing a diamond that was grown in a laboratory over a few weeks and wearing one that formed naturally over billions of years, was found deep within the earth, and travelled through skilled hands before reaching yours.

Both look identical to the naked eye. Both will pass a standard diamond tester. But one has a story that no technology can manufacture.

Fine jewellery has always carried emotional meaning — an engagement ring, an anniversary piece, something passed from one generation to the next. That meaning is tied to what the piece actually is, not just what it looks like. A natural diamond brings something to that moment that a lab stone, however beautiful, simply cannot.

We are not telling you which to choose. We are telling you what we have seen over 20 years in this trade — and what we believe every buyer deserves to know before they decide.
