The same design, the same photograph, the same specification. The stone in one grew in the ground and the stone in the other grew in a reactor. What changes is the price and the laboratory that reported on it, and both are printed above.

Where we stand

A natural diamond and a laboratory-grown diamond are the same material. Same chemistry, same hardness, same behaviour in light. They differ in how they formed, and in what the market charges for them.

So we put both versions of a design on one page, photographed from the same frame, specified line for line, each with its own price and its own laboratory report. We do not tell you that one is the sensible purchase and the other is the romantic one. That is not a decision a shop should be making on your behalf.

Two identical solitaire rings either side of a single fine gold line

One ring, photographed twice, either side of the line. Which of the two is the mined stone is not something the picture can tell you, and that is the entire reason the specifications are printed instead.

Natural / Lab-grown

The mechanism

One table, no adjectives

Every paired design has this table on its page. It is generated from a fixed list of factual fields, so there is nowhere for a persuasive sentence to sit. Read down the two columns and the difference between the two rings is exactly as large as it actually is.

Side by sideClassic Six-Claw Solitaire 0.50 ct, 18ct goldA natural diamond and a laboratory-grown diamond are the same material: the same chemistry, the same hardness, the same optical behaviour. They differ in how they formed and in what the market charges for them. Both are shown here with the same specifications and the same photograph, and this shop takes no position on which you should choose.

Four things we put in front of you before you order

i

A report on every stone that warrants one

Any centre stone of 0.30 ct or more is sold with an independent laboratory report, and the issuing laboratory is named in full. Where there is no report — the cluster and the multi-stone bands — no colour, clarity or cut grade is quoted at all, because there would be nothing behind it. Total carat weight is always labelled as a total, never used to suggest the size of one stone.

Diamond declarations

ii

A hallmark on every ring that needs one

Under the Hallmarking Act 1973 an article of gold over 1 g or platinum over 0.5 g cannot lawfully be described as precious metal without being hallmarked. Wedding rings are well over both. Every precious metal ring here carries its marks, and the net weight and assay office are printed on the page.

Hallmarking and the Dealer's Notice
iii

Whether it can be resized, and why not

Every ring states its resizing window: plus or minus three sizes on a plain band, one size on a set band, and none at all on a full eternity ring, where stones run the whole way round and there is no plain metal to work. Where the answer is no, the page says so in a red panel that cannot be dismissed, with the structural reason next to it.

Resizing policy

iv

How the setting behaves over years, not in the photograph

Claws show the most of a stone and catch the most on knitwear. Bezels sit low and snag least. Pavé gives a continuous line of light and has the shortest inspection interval of anything here. None of these settings is permanent, and we do not say otherwise — have any set ring looked at every twelve to eighteen months.

What people say afterwards

Reviews are published as written. What we will not publish is a review claiming a ring holds its value, or one telling other people how much they ought to spend — those are held for a person to deal with.

Verified against an order

The two columns are the reason I bought here. I had spent a fortnight being told by one shop that lab-grown is not a proper diamond and by another that natural is a con, and neither would put the numbers next to each other. Seeing the same specification twice with two prices under it took about four minutes to decide.
Fiona M., BristolFour-Claw Solitaire 0.70 ct — Lab-grown
The red box saying this one can never be resized is unmissable and it made me stop and get measured properly instead of guessing. Four rather than five only because I would have liked more platinum options in a narrower width.
Priya S., LondonFull Eternity 0.75 ct Total — Lab-grown
Hallmark clearly struck, report in the box, and the net weight matched the page exactly when I had it weighed out of curiosity. Small thing, but it is the sort of thing that tells you the rest of the page is probably true as well.
Aisha R., EdinburghHalf Eternity 0.40 ct Total — Natural
Ordered the sizer first because the site more or less insists on it. Glad I did, I was a full size out from what I had assumed. The band arrived four days later and the fit is right. The sizer cost came off as promised, no chasing needed.
Daniel O., LeedsCourt Band 5 mm — 18ct
I work with my hands and every jeweller I spoke to still tried to sell me a claw setting. This was the first site that said outright which setting snags and which does not. The bezel has been through six months of joinery without a mark on the stone.
Tom H., ManchesterBezel Solitaire 0.40 ct — Natural

Before anything else

Get the size right and almost nothing else can go wrong

Fingers change through the day, with the seasons and with exercise. Measure in the afternoon, measure more than once, and if you are buying without the other person knowing, there are four ways to do it that do not involve asking. A reusable sizer is GBP £5 and the cost comes off your ring in full.
