The debate around natural versus lab grown diamonds has generated more heat than it probably deserves. Depending on which jeweller you talk to, lab grown diamonds are either the obvious choice for a savvy modern buyer, or a category that represents a fundamental misunderstanding of what makes a diamond meaningful.
Neither position is entirely right. And at Micheli, we don't have a stake in which direction you choose. We offer both, and we'll tell you honestly what the differences actually are.
Here's the unvarnished version.
What's Actually the Same
A lab grown diamond is chemically, physically, and optically identical to a natural diamond. It has the same crystal structure, the same hardness (10 on the Mohs scale), the same refractive index, the same fire and brilliance. It is a diamond, grown in a controlled environment rather than formed over billions of years underground, but a diamond nonetheless.
It's graded on the same 4Cs scale by the same independent labs. It requires the same skilled cutting and setting. It will look identical to a natural diamond of equivalent grade in every lighting condition, in every photograph, to every person who sees it.
If someone tells you lab grown diamonds are 'fake' or 'not real,' that's simply incorrect.
What's Actually Different
Origin. A natural diamond was formed between one and three billion years ago, under conditions of extreme heat and pressure deep in the earth's mantle. That geological journey is genuinely unrepeatable. For some people, this matters enormously — the ring becomes a piece of earth's history, a finite thing that cannot be manufactured. For others, this is interesting context that doesn't significantly change how they feel about the stone.
Price. Lab grown diamonds are significantly less expensive than natural diamonds of equivalent grade, often 50 to 80 percent less, depending on the market at the time of purchase. This is a meaningful difference. It means a larger stone, a higher quality grade, or significant budget freed up for the setting, for other life priorities, or simply kept.
Resale value and long-term value. This is where honest advisors have to tell you something the industry doesn't always lead with: the resale value of lab grown diamonds has fallen substantially as supply has increased, and there is no established secondary market that holds prices in the way natural diamonds historically have. A natural diamond, while not a guaranteed investment, has maintained more of its value over time. If long-term value matters to you, this is a relevant consideration.
Environmental footprint. Both natural mining and lab growing have environmental impacts — mining through land disruption, lab growing through significant energy consumption. The honest answer is that neither is straightforwardly 'greener' than the other; the right comparison depends on the specific mining operation and the energy source of the specific growth facility. We won't tell you one is ethically superior without caveats.
The Questions Worth Asking Yourself
Does the origin of the stone matter to you, emotionally or symbolically? If the idea of a stone formed over a billion years carries meaning, if that's part of what makes the ring feel significant, then a natural diamond is the right choice, and the premium is paying for something real.
Is budget a genuine constraint? If a larger, higher-quality stone would bring more joy than a smaller natural one, and the long-term value difference doesn't concern you, then lab grown is a completely rational choice. The stone will be beautiful. The ring will be beautiful. No one who looks at it will know the difference.
What are your values around sustainability and ethics? This one requires a nuanced answer, which we're happy to give in full during a consultation. The short version: both categories have trade-offs, and the right choice depends on which trade-offs you're more comfortable making.
Our Position
We offer both, and we think both are legitimate choices for different buyers with different priorities. What we won't do is push you toward one or the other based on margin, trend, or ideology.
What we will do is have a genuine conversation about what matters to you. Your budget, your values, what you want this ring to mean, and help you make a decision you'll feel completely at ease with, now and in thirty years.
Come in and let's talk through it properly.
