Let me settle the first question straight away, because it is the one everyone asks at the counter: yes, a lab-grown diamond is a real diamond. Same carbon, same crystal structure, same fire under the loupe. At the setting bench, where I have spent most of my working life, my tools cannot tell the difference — because there isn’t one to feel.
What differs is the journey the stone has taken to reach the bench, and the price it carries when it arrives. Both are worth understanding before you choose.
What the certificate tells you
Every diamond we set, grown or mined, comes with an independent certificate — IGI or GIA — grading the same four things: cut, colour, clarity and carat. Read the certificate before you fall for the stone. A well-cut lab diamond will outshine a poorly cut mined one every time, at any budget; cut is where the light lives.
The honest differences
A mined diamond is a one-and-a-half-billion-year-old object, and some clients rightly treasure that. A lab-grown stone is typically weeks old and costs a fraction as much — which in practice means a larger or finer stone for the same budget, or the same stone with money left for the honeymoon. Traceability is simpler with grown stones; romance, for some, sits with the mined ones. Neither answer is wrong.
“Cut is where the light lives. A well-cut lab diamond will outshine a poorly cut mined one at any budget.”
What I tell clients
I ask what the ring is for. An heirloom to pass down carries whatever meaning you give it — and in thirty years I have never seen a marriage improved by the geology of the stone. If the choice is between a modest mined diamond and a beautifully cut lab-grown stone a full carat larger, most of my clients choose the latter and never look back.
What I will not do is set a stone without paperwork, of either kind. Provenance is not a luxury; it is the difference between a diamond and a story about a diamond.
See them side by side
The best way to decide is not an article — it is a pair of tweezers. Come to the workshop and look at grown and mined stones side by side under the daylight lamp. Ten minutes with a loupe answers more than ten hours of reading.
