What identical actually means here
Chemically, physically, and optically the same material. A 10 on the Mohs hardness scale, same as mined. The same refractive index, which is what produces the sparkle. A jeweller with a loupe cannot separate them, and neither can we.
Telling them apart takes specialised laboratory equipment reading growth patterns and trace elements, which is exactly why reputable lab-grown stones carry a laser inscription on the girdle. If someone offers you a lab-grown stone with no report and no inscription, that is the thing to ask about.
How they are grown
Two methods. High pressure, high temperature recreates the conditions a diamond forms under underground. Chemical vapour deposition builds the crystal layer by layer out of carbon gas in a chamber. Both take weeks rather than geological time, and both produce the same material.
The price gap
Lab-grown sells for a fraction of a comparable natural stone, and the gap has widened as production has scaled up. The practical effect is simple: the same budget buys noticeably more carat weight, a higher colour grade, or a cleaner clarity grade. Often all three.
The part that usually gets skipped: resale
Natural diamonds have a secondary market. Lab-grown prices have fallen as supply has grown, and a lab-grown stone bought today is unlikely to resell for what you paid for it. We would rather you heard that from us now than found it out later.
Whether it matters depends entirely on what the ring is for. If the stone is going to be handed to someone in forty years, it matters. If it is a ring you intend to wear until the metal gives out, it does not.
Which one would we put you in?
If you want the largest, cleanest stone your money will reach and resale is not in your thinking, lab-grown. If you want the stone to carry value beyond the ring itself, natural.
We stock both, and we will quote both on the same setting, side by side, so you are looking at a dollar figure rather than at an argument. Most people decide in the time it takes to read the two numbers.
