The straight version
Lab-grown vs mined diamonds
This is normally answered by whoever has an interest in the answer. Here is the version that includes the parts that cost us money to tell you.
They are the same material
A lab-grown diamond is carbon in a diamond lattice, the same as a mined one. Same hardness (10 on the Mohs scale), same refractive index, same brilliance, same everything that determines how it looks on a hand and how long it lasts.
The difference is where it formed and how long it took: a few weeks in a machine, or a billion years underground. That is a real difference in provenance and in what it cost to produce. It is not a difference in the material you wear.
You cannot see the difference
A jeweller's loupe will not do it. Neither will a microscope. Detecting a lab-grown diamond requires a laboratory instrument that analyses how the crystal grew — which is why both kinds come with an independent certificate rather than taking anyone's word.
What actually differs
The two lines people find hardest are the resale ones, so let us say it plainly: diamonds are not a good investment, and this is true of mined ones too. The difference is that a lab-grown stone costs you less to begin with, so starting lower is less to lose.
| Lab-grown | Mined | |
|---|---|---|
| Cost, 1 carat ring, all in | About $1,380 with us | About $7,600 average |
| Resale value | Low | Also weaker than people expect |
| Supply | Effectively unlimited | Finite |
| Mining impact | None | Substantial |
| Looks on a hand | Identical | Identical |
| Durability | Identical | Identical |
The resale question, answered properly
If you buy a mined diamond for $7,600 and try to sell it, you will not get $7,600 back — retail and resale are different markets, and the gap is wide. So the honest comparison is not “invests vs does not”. It is “loses a lot on a bigger number” versus “loses proportionally more on a much smaller number.”
If resale genuinely matters to you, the sensible move is to spend less and put the difference somewhere that is actually an asset. We would rather tell you that than sell you the bigger stone.
Where the money goes
Ours goes to a workshop we have worked with for years and to the hand that sets and finishes your ring in St. George. No mining, no showroom, no national advertising budget, no middleman.
That last part is not a marketing line, it is arithmetic: the reason a lab-grown ring can be this much cheaper is that growing a stone costs a fraction of digging one up.
So which should you buy?
- Lab-grown if you want the biggest, cleanest stone your budget allows, you do not plan to resell, and the mining question matters to you.
- Mined if the provenance itself means something to you, or to her, in a way that a certificate cannot substitute for. That is a legitimate reason and we will help you either way.
- If you are unsure: come and look at both and decide with your eyes rather than from a webpage. Nobody has ever regretted buying the one they loved more.
Questions people actually ask
Are lab-grown diamonds fake?
No. Fake diamond usually means cubic zirconia or moissanite, which are different materials entirely. A lab-grown diamond is a diamond — the same carbon crystal — made in a machine instead of underground.
Do lab-grown diamonds hold their value?
Not well, and mined diamonds do not hold it as well as people believe either. Neither is an investment. Buy the one you like, and treat the difference as money saved rather than an asset purchased.
Will a jeweller know it is lab-grown?
Only with a laboratory instrument. It is not visible through a loupe, which is why the certificate matters more than anyone's eye.
Are mined diamonds better quality?
No. Both are graded on the same scale by the same laboratories. A well-graded lab-grown stone is a better stone than a badly-graded mined one, and it is considerably cheaper.
