Every single lab diamond starts as a tiny fragment of a mined diamond, which is exposed to&#xA0;<strong>carbon</strong>. Carbon is the natural element that all diamonds are formed from, whether they come from the earth or from a high-tech laboratory.</p><p>Next, extreme pressure and heat are applied. This process&#xA0;<strong>imitates nature&#x2019;s intense volcanic forces</strong> that once created diamonds under the earth.</p><p>Gradually, the carbon atoms crystalise around the diamond fragement. Over a few weeks, it&#xA0;<strong>grows into a rough diamond</strong>, large enough to be carved into a beautiful gem.</p></div></div><div data-js-accordion="all"><h2 data-js-accordion-button id="sustainability">SUSTAINABILITY</h2><div data-js-accordion-content><p>Lab grown diamonds are environmentally<strong>&#xA0;ethical and sustainable</strong>. Their carbon footprint is much smaller than that of mined diamonds, because they are not extracted from the earth.</p><p>While our mined diamonds are also ethical because they are conflict-free, our lab grown diamonds give you a further choice: jewellery that&#xA0;<strong>nurtures the Earth</strong> for future generations.</p></div></div><div data-js-accordion="all"><h2 data-js-accordion-button id="buying-guide">BUYING GUIDE</h2><div data-js-accordion-content><h3 id="how-should-you-assess-a-lab-grown-diamonds-quality-and-value">How should you assess a lab grown diamond&#x2019;s quality and value?</h3><p>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 diamonds. This is done by evaluating the &#x201C;Four Cs&#x201D; &#x2013; cut, colour, clarity and carat weight.</p><h4 id="colour">COLOUR</h4><p>For mined and lab diamonds alike, the less yellow colour your diamonds exhibits, the better its colour-quality. In other words, you want your diamond to be as &#x201C;sparkling white&#x201D; and transparent as possible.</p><p>To determine this, gem experts give diamonds colour grades using letters from D to Z. Take a look at the diagram below to see how this scale works.</p><p>D is the best colour grade, while Z is the poorest. If you are shopping for diamond jewellery, then any colour grade from E to H is a great option.</p><p><br></p><h4 id="clarity">CLARITY</h4><p>All diamonds have some imperfections. Gemmologists call these tiny markings &#x201C;inclusions&#x201D;. The less inclusions your diamond has, the better its clarity.</p><p>Remember, lab diamonds are grown in a way that imitates Mother Nature. Therefore, they are not free from natural imperfections.</p><p>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).</p><p>Luckily, lab diamonds are created in a laboratory. Therefore, it is reasonably cost-effective to select the clearest diamonds from each batch that is grown. What does this mean for the consumer? It means that you can expect to buy a much higher-clarity lab grown diamond for your budget, than if you were shopping for an equivalent-sized mined diamond.</p><p><br></p><h4 id="cut">CUT</h4><p>When we speak about a diamond&#x2019;s &#x201C;cut&#x201D;, many people think about its decorative shape. For example, you might imagine a classic round cut diamond or a square princess cut diamond.</p><p>However, in reality, when we talk about &#x201C;cut quality&#x201D;, it refers to how well the diamond plays with light.</p><p>A good diamond cut should make your diamond sparkle beautifully. 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.</p><p><br></p><h4 id="carat">CARAT</h4><p>&#x201C;Carat&#x201D; refers to a diamond&#x2019;s weight. In other words, it tells us how big the diamond is. You&#x2019;ll often see carat weight abbreviated to &#x201C;CT&#x201D;. For example, 1.00CT means one carat and 0.50CT means half a carat.</p><p>A diamond&#x2019;s price is not necessarily determined by its carat size. Remember, all Four C&#x2019;s must be taken into account. However, the good news is that lab diamonds are around 50-60% more affordable per carat than mined diamonds.</p><p>Therefore, you&#x2019;ll usually be able to purchase a much larger lab diamond for your budget than if you were buying a mined diamond of the equivalent quality.</p><p><br></p><h4 id="what-about-coloured-diamonds">WHAT ABOUT COLOURED DIAMONDS</h4>Apart from colourless (or white) lab grown diamonds there are also so called &#x201C;fancy coloured&#x201D; lab diamonds.

Give your diamond jewellery a gentle scrub, then rinse and pat dry.</p><p>Never wash your jewellery over a sink. Use a bowl instead. Should a diamond come loose, this way it cannot disappear down the drain.</p></div></div><div data-js-accordion="all"><h2 data-js-accordion-button id="famous-diamonds">FAMOUS DIAMONDS</h2><div data-js-accordion-content><p>The very definition of diamonds is changing thanks to state of the art technology and the value we put on sustainability.

If you are concerned about the carbon footprint of diamond mining, then lab diamonds that nurture our Earth for future generations are the perfect choice for you.</p></div></div>

Every single lab diamond starts as a tiny fragment of a mined diamond, which is exposed to&#xA0;<strong>carbon</strong>. Carbon is the element that all diamonds are created from, whether earth-mined or lab-grown.<br><br>Earth-mined yellow diamonds owe their colour to nitrogen trace elements. When it comes to lab grown yellow diamonds, the same&#xA0;<strong>natural colouration</strong> is achieved through a process that imitates nature.</p><p>In the laboratory, scientists introduce&#xA0;<strong>nitrogen trace elements</strong> while the diamond grows. This results in beautiful, naturally yellow colour within the diamond crystal.</p><p>Over a few weeks, the carbon atoms crystalise and grow into rough yellow diamonds. Once they&#x2019;re large enough, they can be carved into beautiful gems and worn in jewellery.</p></div></div><div data-js-accordion="all"><h2 data-js-accordion-button id="sustainability">SUSTAINABILITY</h2><div data-js-accordion-content><p>Yellow lab grown diamonds are environmentally&#xA0;<strong>ethical and sustainable</strong>. Their carbon footprint is much smaller than that of mined diamonds, because they are not extracted from the earth.</p><p>While our mined diamonds are also ethical because they are conflict-free, our lab grown diamonds give you a further choice: jewellery that&#xA0;<strong>nurtures the Earth</strong> for future generations.</p></div></div><div data-js-accordion="all"><h2 data-js-accordion-button id="buying-guide">BUYING GUIDE</h2><div data-js-accordion-content><h3 id="how-should-you-assess-a-yellow-lab-grown-diamonds-quality-and-value">How should you assess a yellow lab grown diamond&#x2019;s quality and value?</h3><p>Yellow 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 yellow diamonds. This is done by evaluating the &#x201C;Four Cs&#x201D; &#x2013; cut, colour, clarity and carat weight, with special importance placed on pure and even colour.</p><h4 id="colour">COLOUR</h4><p>When it comes to white diamonds, they usually decrease in value if any colouration is seen in their transparent crystals.</p><p>For coloured diamonds, the opposite is true. The better their colour, the higher their value.</p><p>However, grading coloured diamonds is a complicated and specialized process. What&#x2019;s more, just like earth-mined yellow diamonds, lab grown yellow diamonds can vary in shade from light to intense. This is completely natural, same as it would be in earth-mined yellow diamonds. Don&#x2019;t forget, no two diamonds are exactly alike!</p><p>Therefore, you should look for evenness and purity of colour, rather than an individual tone or shade which can vary from diamond to diamond.</p><p><br></p><h4 id="clarity">CLARITY</h4><p>All diamonds have some imperfections. Gemmologists call these tiny markings &#x201C;inclusions&#x201D;. Generally speaking, the less inclusions your diamond has, the better its clarity. Remember, that yellow lab diamonds are grown in a way that imitates Mother Nature. Therefore, they are not free from natural imperfections.</p><p>When it comes to earth-mined yellow diamonds, inclusions are tolerated by gem connoisseurs. This is because mined yellow diamonds are incredibly rare. Even a poor-clarity mined yellow diamond can fetch prices starting from around &#xA3;3,000 per carat.</p><p>Luckily, yellow lab grown diamonds are created in a laboratory. This means that it is reasonably cost-effective to select the clearest yellow diamonds from each batch that is grown.</p><p>What does this mean for the consumer? It means that you can expect to find a far better clarity of yellow lab diamond for your budget, than if you were shopping for an equivalent-sized yellow mined diamond.</p><p>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).</p><p><br></p><h4 id="cut">CUT</h4><p>When we speak about a diamond&#x2019;s &#x201C;cut&#x201D;, many people think about its decorative shape. For example, you might imagine a classic round cut diamond or a square princess cut diamond.</p><p>However, in reality, when we talk about &#x201C;cut quality&#x201D;, it refers to how well the diamond plays with light.</p><p>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.</p><p>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.</p><p><br></p><h4 id="carat">CARAT</h4><p>&#x201C;Carat&#x201D; refers to a diamond&#x2019;s weight. In other words, it tells us how big the diamond is. You&#x2019;ll often see carat weight abbreviated to &#x201C;CT&#x201D;. For example, 1.00CT means one carat and 0.50CT means half a carat.</p><p>A yellow lab diamond&#x2019;s price is not necessarily determined by its carat size. Remember, all Four C&#x2019;s, and in particular purity and evenness of colour, must be taken into account.</p><p>However, the good news is that coloured lab diamonds award you up to 75% more carats for your budget, compared to mined ones.</p><p>Therefore, you will definitely be able to purchase a much, much larger yellow lab grown diamond for your budget, than if you were buying a mined yellow diamond of the equivalent quality.</p><p><br></p><h4 id="what-about-other-lab-diamond-colours">WHAT ABOUT OTHER LAB DIAMOND COLOURS?</h4>We also offer sustainable white lab grown diamonds and yellow and blue lab diamonds in our online store. You&#x2019;ll find a Gem Guide for each one, under&#xA0;<a href="https://www.thediamondstore.co.uk/pages/gemguides-sustainable-lab-grown-diamond" style=" text-decoration: none;">White Lab Diamonds</a>,&#xA0;<a href="https://www.thediamondstore.co.uk/pages/gemguides-sustainable-pink-lab-grown-diamond-meaning-tips-and-guide" style=" text-decoration: none;">Pink Lab Diamonds</a> and&#xA0;<a href="https://www.thediamondstore.co.uk/pages/gemguides-sustainable-blue-lab-grown-diamond-meaning-tips-and-guide" style=" text-decoration: none;">Blue Lab Diamonds</a>.</div></div><div data-js-accordion="all"><h2 data-js-accordion-button id="are-yellow-lab-diamonds-real-diamonds">ARE YELLOW LAB DIAMONDS REAL DIAMONDS?</h2><div data-js-accordion-content><p>Yes, yellow lab diamonds are real diamonds. Gemmological experts classify coloured lab grown diamonds simply as, coloured diamonds. This is because they posses&#xA0;<strong>the same physical and chemical composition</strong> as the diamonds we mine from the earth.</p><p>It&#x2019;s vital to understand that yellow lab diamonds are&#xA0;<strong>NOT synthetic</strong> diamond &#x201C;substitutes&#x201D;. They are not like cubic zirconia, moissanite or other simulants, which are manufactured from materials that have nothing to do with diamonds.</p><p>Because yellow lab grown diamonds&#xA0;<strong>look the same as yellow mined diamonds</strong>, for consumer transparency they all carry a microscopic laser mark. This way, jewellers can tell them apart with specialist magnifying equipment.</p></div></div><div data-js-accordion="all"><h2 data-js-accordion-button id="are-yellow-lab-diamonds-certified">ARE YELLOW LAB DIAMONDS CERTIFIED?</h2><div data-js-accordion-content><p>Yes. Same as mined diamonds, yellow lab diamonds can be certified to prove their&#xA0;<a href="https://www.thediamondstore.co.uk/pages/4cs" style=" text-decoration: none;">Four Cs</a> and origin.</p><p>However, note that not all yellow 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.</p><p>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.</p><p><a href="https://www.thediamondstore.co.uk/pages/diamond-certificates" style=" text-decoration: none;">READ MORE ABOUT DIAMOND CERTIFICATION HERE</a></p></div></div><div data-js-accordion="all"><h2 data-js-accordion-button id="birthstone-and-anniversary">BIRTHSTONE AND ANNIVERSARY</h2><div data-js-accordion-content><p>Diamonds are the&#xA0;<strong>birthstone for April</strong>. This applies to all diamonds, be they earth-mined, lab grown, pink, yellow or blue.</p><p>Because of their durable nature, they represent lasting love and affection. That&#x2019;s why they&#x2019;re so often used in symbolic jewellery, especially in engagement rings.</p><p>Diamonds are traditionally gifted on&#xA0;<strong>10th anniversaries</strong> and&#xA0;<strong>60th Diamond Jubilee Wedding Anniversaries</strong>, but their beauty and value mean they&#x2019;re well suited to any important occasion.</p></div></div><div data-js-accordion="all"><h2 data-js-accordion-button id="cleaning-and-care">CLEANING AND CARE</h2><div data-js-accordion-content><p>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&#x2019;re&#xA0;<strong>precious and rare gems</strong>.</p><p>The&#xA0;<strong>safest way</strong> to clean your yellow 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.</p><p><strong>Never wash your diamond jewellery over a sink</strong>. Use a bowl instead. Should a diamond come loose, this way it cannot disappear down the drain.</p></div></div><div data-js-accordion="all"><h2 data-js-accordion-button id="famous-pink-lab-grown-diamonds">FAMOUS PINK LAB GROWN DIAMONDS</h2><div data-js-accordion-content><p>The very definition of diamonds is changing thanks to state of the art technology and the value we put on sustainability. This is especially true for&#xA0;<strong>modern celebrities and fashion lovers</strong>.</p><p>Lady Gaga, Penelope Cruz, Meghan Markle, Emma Watson and Zoe Kravitz are just a few of the big stars who habitually flaunt sustainable lab grown diamonds on red carpets.</p></div></div><div data-js-accordion="all"><h2 data-js-accordion-button id="value-and-pricing">VALUE AND PRICING</h2><div data-js-accordion-content><p>Yellow lab grown diamonds are a&#xA0;<strong>luxury</strong>. 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.</p><p>Just the same as yellow mined diamonds, the price of yellow lab diamonds varies according to the&#xA0;<strong>Four Cs</strong> &#x2013; colour, clarity, cut and carat weight.</p><p>The good news for consumers is that if you compare a yellow mined and a yellow lab diamond of the same quality and size, you&#x2019;ll get&#xA0;<strong>up to 75% more carats</strong> for your budget if you buy the lab grown variety.</p><p>Finally, adding un-measurable value to yellow lab diamonds is their&#xA0;<strong>sustainability</strong>. If you are concerned about the carbon footprint of diamond mining, then yellow lab diamonds, which nurture our Earth for future generations, are the perfect choice for you.</p></div></div><p><br></p><p><br></p><p><br></p><p><br></p><p><br></p><p><br></p>
