Search "pink diamond price" or "blue diamond price" and you land in two worlds that never meet. On one side, natural stones with six figure tags, reserved for auction rooms. On the other, lab-grown diamond charts that only ever talk about white. In between, nothing. Nobody publishes what a ring set with a blue, green, pink or yellow lab-grown diamond actually costs. We sell them, so we can say it. Here is a grid built on finished rings.

What sets the price of a coloured diamond

Before the numbers, the mechanics. Six factors drive the price, and they do not carry the same weight.

Origin. Natural or lab-grown. By far the first factor, with gaps counted in multiples.

Hue. On the natural market, red and blue are the rarest, yellow the most common. In the lab, that hierarchy flattens out.

Intensity. The criterion that matters most on a coloured stone. The same blue can be graded Faint, Light, Fancy, Fancy Intense or Fancy Vivid. Saturation moves the price far more than clarity does.

Carat. The price is never linear. One 1 carat stone costs clearly more than two 0.5 carat stones.

Cut. Not the weight, the shape. An Asscher or a pear does not consume the same rough as a round brilliant. Some cuts lift the colour, others dilute it.

The metal of the setting. Underrated everywhere, and often the biggest single line in the gap between two identical rings.

We will not redo the 4Cs here: our diamond buying guide already covers them.

Natural or lab-grown: the real price gap

Let us set the order of magnitude. A natural coloured diamond is a collector's object. As an indication only, and taking the ranges published by diamants-infos.com, a 1 carat natural pink trades between 115 569€ and 401 070€. A blue, between 128 176€ and 623 886€. A green, between 40 305€ and 445 633€. A yellow, far more common, between 3 119€ and 10 695€.

Those figures are not ours. They are quoted as they stand from a competitor source consulted in August 2026, given purely as an indication, and they swing enormously with intensity. We cite them to show that the natural coloured diamond does not belong to the same market as the piece of jewellery you are looking for.

On the lab-grown side, the published charts only cover white. Laveran-paris.com quotes, again as an indication, 1 200€ to 2 400€ for a colourless carat of standard quality. Those are loose stone prices, not ring prices. For coloured lab-grown diamonds, the search results are empty. That is the hole we are filling.

The Lauredi grid: finished ring prices, colour by colour

One warning first. We do not publish a price per carat: a carat price on its own tells a buyer nothing. We publish the real prices of our finished rings, set and IGI certified. Each price runs from the 925 silver model to the same model in recycled 18 carat gold.

Faubourg 1925 Baby One Ring, one brilliant diamond. From 190€ to 850€. In blue, green, pink, yellow and white. The absolute entry point into a coloured lab-grown diamond ring.

Faubourg 1925 Baby Ring, one brilliant diamond. From 290€ to 1550€. Same colours.

Faubourg 1925 Ring, Asscher cut. From 990€ to 3600€. All five colours at the same price.

Andrea Ring, 0.5 carat brilliant solitaire. From 990€ to 2200€ in blue, green or pink. In white, from 990€ to 1990€.

Christine Ring, art deco. From 1190€ to 2900€ in blue, green or pink. In white, from 1190€ to 2100€.

Loop Solitaire Ring, pear diamond. From 990€ to 4990€ in blue, green or pink. In white, from 990€ to 3990€.

Faubourg 1925 Necklace, Asscher cut diamond. From 1490€ to 4150€, in all five colours.

Three counter intuitive lessons sit inside that grid.

In 925 silver, colour costs nothing extra. The Andrea Ring starts at 990€ whether the stone is white, blue, green or pink. The Christine starts at 1190€ in every case.

The colour premium shows up in recycled 18 carat gold: 210€ on the Andrea Ring, 800€ on the Christine, 1000€ on the pear Loop Solitaire. It depends on the size of the stone, not on the price of the model.

And on the Asscher cut Faubourg 1925 Ring, colour costs nothing at all, even in gold: 990€ to 3600€ across the five shades.

Same stone, two prices: what the metal does

This is the most misread gap in the whole of fine jewellery. Take the clearest example in our catalogue.

The Andrea blue diamond ring costs 990€ in 925 silver. The same ring costs 2200€ in recycled 18 carat gold. It is exactly the same stone: same 0.5 carat blue lab-grown diamond, same IGI certification, same design, same setting.

So where does the 1210€ gap come from? From the metal price: 18 carat gold holds 75 % fine gold and tracks the world market, while 925 silver trades on another scale entirely. From the mass: a band and a setting basket add up to several grams. And from the labour.

What that means for you. If the stone is your priority, take 925 silver and put the budget into a better diamond. If permanence is your priority, take recycled 18 carat gold and accept a smaller stone. What makes no sense is believing that a 2200€ ring holds a better stone than the same ring at 990€.

Blue, green, pink, yellow: what each colour costs here

On the natural market, the hierarchy of colours is brutal. Here, it is almost flat.

Blue. The most requested colour. In the lab it comes from introducing boron. From 190€ to 4990€ with us. If you are hesitating with another blue stone, our comparison blue diamond or sapphire settles the question.

Green. The hardest to grow evenly and the most variable under different light. Same grid as blue.

Pink. On the natural market, this is the colour of auction records. Grown in a lab, it becomes reachable: from 190€ to 4990€. A pink diamond is set on recycled 18 carat yellow gold, on white gold, on 925 silver or on vermeil.

Yellow. On the Faubourg 1925 line, from 190€ to 3600€, and from 1490€ to 4150€ on the necklace. The easiest shade to wear every day.

The takeaway: here, colour does not set the price. The model and the metal set it. That is the opposite of the natural market.

How the setting changes the way you read the colour

Nobody talks about this, and yet it decides a lot when you are paying for a colour. A coloured diamond is transparent: it gives back part of what surrounds it. The metal acts as a filter on the shade you perceive.

On 925 silver and recycled 18 carat white gold. The metal is cool and neutral. A blue looks crisper, a green looks truer. The best choice for reading a colour exactly as it is.

On recycled 18 carat yellow gold. The metal warms the stone. A yellow intensifies and melts into the setting. A pink softens. A green drifts towards olive.

On vermeil. The same visual effect as yellow gold, for a far smaller budget. The limit is well known: the gold layer wears down over the years, above all at the friction points.

The practical consequence. If you are paying for an intense colour, put it on a cool metal. If you want a soft, integrated colour, recycled 18 carat yellow gold does the job.

Value over time, said honestly

The question always comes up, and the market answers swing between lying and awkward silence. A lab-grown diamond is not an investment. It has no structured resale market, and its production cost has fallen. Buying a ring hoping to resell it at a profit is a mistake, whatever the colour.

Two things do hold value, though. The metal: recycled 18 carat gold has an intrinsic value tied to the world price, it can be melted and reworked. And the stone as an object: a lab-grown diamond does not scratch and does not fade. In thirty years it will be the same.

What you are buying is a piece worn for a long time and passed on. Not a line in a portfolio. We go deeper into this in our article on the price of a diamond.

How to spend your budget

Three concrete scenarios, with real prices.

Up to 300€. A ring with a real IGI certified coloured lab-grown diamond, in 925 silver. The Faubourg 1925 Baby One at 190€ or the Baby at 290€. Do not look for gold here, you will only find plating.

Around 1000€. A 0.5 carat coloured solitaire in 925 silver, with the Andrea Ring at 990€. Or a smaller ring in recycled 18 carat gold. The stone or the material: your call.

From 2000€ to 3000€. The threshold where a coloured solitaire in recycled 18 carat gold becomes reachable. The Andrea blue diamond ring at 2200€, the Christine at 2900€.

To compare shades, our dedicated collections help: blue diamonds and green diamonds.

What to remember

The natural coloured diamond belongs to a collector's market. That is not the subject here.

The coloured lab-grown diamond, on the other hand, is made to be worn. A ring with an IGI certified blue, green, pink or yellow diamond starts at 190€ in 925 silver and climbs to 4990€ in recycled 18 carat gold.

The most important point: with us, colour is not what makes the price, the metal is. The Andrea blue diamond ring at 990€ and the one at 2200€ carry exactly the same stone.

To go further. On yellow in particular, our yellow diamond collection shows why the same shade can read as a flaw or as a value. To check what you are buying, read how to identify a lab-grown diamond. And to see how the setting changes the result, browse our rings.

FAQ

How much does a pink diamond cost?

It all depends on the origin. A 1 carat natural pink goes beyond 100 000€ according to specialist sites. A ring with an IGI certified pink lab-grown diamond starts at 190€ at Lauredi, in 925 silver.

How much does a blue diamond cost?

A 1 carat natural blue goes well beyond 100 000€ according to specialist sources. Lab-grown, our 0.5 carat Andrea blue diamond ring runs from 990€ in 925 silver to 2200€ in recycled 18 carat gold.

Why is a natural green diamond so expensive?

Because its colour comes from rare, often surface deep irradiation. Few stones keep an even shade once cut. Grown in a lab, green sells here at the same price as blue and pink.

Is a coloured lab-grown diamond a real diamond?

Yes. Same composition, same hardness, same optical behaviour. The only difference is where it came from.

Why does the same ring cost twice as much in 18 carat gold?

Because the metal, not the stone, accounts for almost all of the gap. 18 carat gold holds 75 % fine gold and follows the world price. The Andrea blue diamond ring goes from 990€ to 2200€ with exactly the same diamond.

Which diamond colour offers the best value for money?

With us, no colour costs more than another on the same model in 925 silver. Value is decided by the model and the metal, not by the shade.

Does a lab-grown diamond lose value over time?

There is no structured resale market, so it should not be bought as an investment. Its value in use does not move: it does not scratch and does not fade. The metal of the setting does keep an intrinsic value.
