pink lab diamond facts

Hard Facts

Sustainable pink lab grown diamonds are real diamonds, just like mined pink diamonds. Physically and chemically the same as their earth-mined counterparts, they’re also equally vividly coloured, beautiful and sparkling. The only difference is their origin.

Scientists grow pink lab diamonds in a laboratory using a method that imitates the way Mother Nature formed pink diamonds under the earth.

Pink lab grown diamonds offer superb natural colour, beautiful sparkle and exceptional value. What’s more, they’re a sustainable choice.

How are pink lab diamonds grown?

Growing real pink diamonds in a laboratory is fascinating. Every single lab diamond starts as a tiny fragment of a mined diamond, which is exposed to carbon. Carbon is the element that all diamonds are created from, whether earth-mined or lab-grown.

Mined pink diamonds owe their colour to a particular way in which they refract light, which makes us perceive them as pink. When it comes to lab grown pink diamonds, this same natural refraction can be achieved through three different methods.

These include extreme heat, altered pressure and irradiation, which replicate the way in which intense volcanic forces created pink diamonds under the Earth’s surface.

Over a few weeks, the carbon atoms crystalise and grow into rough pink diamonds. Once they’re large enough, they can be carved into beautiful gems and worn in jewellery.

Pink lab grown diamonds are environmentally ethical and sustainable. Their carbon footprint is much smaller than that of mined diamonds, because they are not extracted from the earth.

While our mined diamonds are also ethical because they are conflict-free, our lab grown diamonds give you a further choice: jewellery that nurtures the Earth for future generations.

How to assess a pink lab grown diamond’s quality and value?

Pink lab grown diamonds are real diamonds, created in a way that replicates nature. Therefore, gemmological experts grade them exactly in the same way as mined pink diamonds. This is done by evaluating the “Four Cs” – cut, colour, clarity and carat weight, with special importance placed on pure and even colour.


When it comes to white diamonds, they usually decrease in value if any colouration is seen in their transparent crystals.

For coloured diamonds, the opposite is true. The better their colour, the higher their value.

However, grading coloured diamonds is a complicated and specialized process. What’s more, just like earth-mined pink diamonds, lab grown pink diamonds can vary in shade from light to intense. This is completely natural, same as it would be in earth-mined pink diamonds. Don’t forget, no two diamonds are exactly alike!

Therefore, you should look for evenness and purity of colour, rather than an individual tone or shade which can vary from diamond to diamond.

All diamonds have some imperfections. Gemmologists call these tiny markings “inclusions”. Generally speaking, the less inclusions your diamond has, the better its clarity. Remember, that pink lab diamonds are grown in a way that imitates Mother Nature. Therefore, they are not free from natural imperfections.

When it comes to earth-mined pink diamonds, even multiple inclusions are tolerated by gem connoisseurs. This is because mined pink diamonds are incredibly rare. Even a poor-clarity mined pink diamond can fetch prices starting from around £8,000 per carat.

Luckily, pink lab grown diamonds are created in a laboratory. This means that it is reasonably cost-effective to select the clearest pink diamonds from each batch that is grown.

What does this mean for the consumer? It means that you can expect to find a far better clarity of pink lab diamond for your budget, than if you were shopping for an equivalent-sized pink mined diamond.

FL (flawless) diamonds have the best clarity. Diamonds graded I (visible inclusions) are the poorest. Most people seek diamonds in between the two extremes: VVS (very, very slight inclusions), VS (very slight inclusions) or the most popular grade, SI (some inclusions).

When we speak about a diamond’s “cut”, many people think about its decorative shape. For example, you might imagine a classic round cut diamond or a square princess cut diamond.

However, in reality, when we talk about “cut quality”, it refers to how well the diamond plays with light.

A good diamond cut should make your diamond sparkle beautifully. This depends on the skill and expertise of the diamond cutter who carved and polished the diamond out of a rough gem.

We offer a minimum of Good/Very Good cut in all our over-0.50 carat lab and mined diamonds that have H/Si quality or higher.

“Carat” refers to a diamond’s weight. In other words, it tells us how big the diamond is. You’ll often see carat weight abbreviated to “CT”. For example, 1.00CT means one carat and 0.50CT means half a carat.

A pink lab diamond’s price is not necessarily determined by its carat size. Remember, all Four C’s, and in particular purity and evenness of colour, must be taken into account.

However, the good news is that coloured lab diamonds award you up to 75% more carats for your budget, compared to mined ones.

Therefore, you will definitely be able to purchase a much, much larger pink lab grown diamond for your budget, than if you were buying a mined pink diamond of the equivalent quality.

We also offer sustainable white lab grown diamonds and yellow and blue lab diamonds in our online store. You’ll find a Gem Guide for each one, under White Lab Diamonds, Yellow Lab Diamonds and Blue Lab Diamonds.

real pink lab diamond

Are pink lab diamonds real diamonds?

Yes, pink lab diamonds are real diamonds. Gemmological experts classify coloured lab grown diamonds simply as, coloured diamonds. This is because they posses the same physical and chemical composition as the diamonds we mine from the earth.

It’s vital to understand that pink lab diamonds are NOT synthetic diamond “substitutes”. They are not like cubic zirconia, moissanite or other simulants, which are manufactured from materials that have nothing to do with diamonds.

Because pink lab grown diamonds look the same as pink mined diamonds, for consumer transparency they all carry a microscopic laser mark. This way, jewellers can tell them apart with specialist magnifying equipment.

diamond certification

Are pink lab diamonds certified?

Yes. Same as mined diamonds, pink lab diamonds can be certified to prove their Four Cs and origin.

However, note that not all pink lab or mined diamonds are certified. Why? Diamond certification is an expensive process. Adding this cost to, for example, a small diamond under 0.25 carat would make it unnecessarily and disproportinately expensive.

Who certifies lab grown diamonds? They are certified by exactly the same independent gemmological laboratories that certify mined diamonds. For example, GIA or IGI laboratories.

Birthstone and Anniversary

Diamonds are the birthstone for April. This applies to all diamonds, be they earth-mined, lab grown, pink, yellow or blue.

Because of their durable nature, they represent lasting love and affection. That’s why they’re so often used in symbolic jewellery, especially in engagement rings.

Diamonds are traditionally gifted on 10th anniversaries and 60th Diamond Jubilee Wedding Anniversaries, but their beauty and value mean they’re well suited to any important occasion.

cleaning and care

Cleaning and Care

All diamonds should be cleaned with care and stored in a safe place. Whilst they are the most durable and strong material on Earth, they’re precious and rare gems.

The safest way to clean your pink diamond jewellery is in a bowl of water using a drop of soap and an old toothbrush. Give the jewellery a gentle scrub, then rinse and pat dry.

Never wash your diamond jewellery over a sink. Use a bowl instead. Should a diamond come loose, this way it cannot disappear down the drain.

pink lab diamond value

Value and Pricing

Pink lab grown diamonds are a luxury. As such, they are rare and by no means inexpensive. The perception of their value is simply different because lab diamonds grow withing a few weeks, as opposed to mined diamonds which take billions of years to form.

Just the same as pink mined diamonds, the price of pink lab diamonds varies according to the Four Cs – colour, clarity, cut and carat weight.

The good news for consumers is that if you compare a pink mined and a pink lab diamond of the same quality and size, you’ll get up to 75% more carats for your budget if you buy the lab grown varity.

Finally, adding unmeasurable value to pink lab diamonds is their sustainability. If you are concerned about the carbon footprint of diamond mining, then pink lab diamonds, which nurture our Earth for future generations, are the perfect choice for you.
