First, the word doing the work
Are lab grown diamonds real is a question about vocabulary as much as about stones, because real is being asked to mean two different things at once.
If it means is this material a diamond, the answer is yes, without qualification. Same carbon, same lattice, same hardness, same behaviour in light. Not similar. The same.
If it means did this come out of the ground, then no, and nobody has ever suggested otherwise. The confusion is entirely in the question, and the trade has not always been in a hurry to clear it up.
Myth one: they are fakes
A fake is something pretending to be something else. Cubic zirconia and moissanite are different materials that resemble diamond — those are simulants, and calling them fake is fair enough.
A lab-grown diamond is not resembling anything. It is the material. The distinction matters because the two get lumped together constantly, usually by someone with mined stock to move, and the two things are not remotely comparable.
Myth two: a jeweller can spot one
Not by eye, and not with a loupe, and it is worth being specific because this claim is made confidently by people who believe it about themselves.
Grading laboratories can identify a lab-grown stone using specialised instruments that read the structural signatures left by how it formed. That is a matter of equipment rather than expertise, it is not a judgement call, and it is not contested. The report states plainly what the stone is, and most lab-grown stones also carry an inscription on the girdle.
So nobody is passing anything off. The information is on the paperwork, permanently.
Myth three: they hold no value, and mined stones do
The true half first, since it is the strongest argument against buying one and you should hear it from us.
Lab-grown prices have fallen as manufacturing capacity has expanded, and a stone bought some years ago would not fetch today what was paid for it. That is real.
What almost never follows is the second half. The resale market for mined diamonds is also unkind, and always has been. The gap between what a retail buyer pays and what a dealer will offer to buy the same stone back is wide, and most people meet this fact exactly once, usually while trying to sell something inherited.
So the honest conclusion is not that one is an investment and the other is not. Neither is. If you want an asset, buy an asset — and the full comparison takes that argument further than a myths list can.
Myth four: they are all identical
This one comes from the word manufactured and it does not survive contact with two stones side by side.
Lab-grown diamonds vary in every direction a mined stone does. Cut quality is decided by a human being afterwards and is the single largest influence on how a stone actually looks. Colour and clarity vary. Two stones with identical grades on paper can look different in the hand, which is why choosing by spreadsheet is a mistake regardless of where the carbon originated.
Myth five: they are a lesser version of the same thing
This is the one worth pushing back on, because it is a judgement smuggled in as a fact.
The material is identical and the grading is identical. What differs is origin, price, and what the object means to the person wearing it. Somebody who wants a stone that formed underground before anything else did is not making an error — that is a real preference about origin, and no argument about lattices touches it.
But it is a preference, not a hierarchy. Once someone says lesser, they have stopped describing the stone and started describing what they think you should want.
Where this leaves us
Every stone we work with is a lab-grown diamond, graded independently on the same scales as any other. That is not a compromise we are explaining away. It is what makes the rest of it possible — you cannot grow a diamond from someone's carbon in the ground.
A biological commission is a lab-grown diamond whose carbon began as about five grams of hair or fur, collected and sealed under a documented chain of custody. It carries no DNA, and the sample takes part in the growth rather than constituting all of it. Both of those sentences appear on every page here for the same reason: they are the two things easiest to overstate.
And Custom is the separate thing — a conventionally sourced lab-grown stone, chosen and set by us, with no biological contribution at all. We will never let one be sold as the other, which is what what this is not exists to say in writing.
Real, then, in the only sense the word can carry: it is a diamond, it is graded as one, and everything about where it came from is written down.
