Lab Grown Diamonds

Diamonds, whether natural or lab created, are not certified by default. But jewelers can choose to have their lab created diamonds graded or certified before listing the gems for sale. Independent diamond institutions offer grading for individual diamonds, helping people better understand the durability and appearance of a diamond before making a purchase.

Because lab created diamonds are chemically and optically identical to natural diamonds, they will bring longevity and durability. Lab grown diamonds provide lifetimes of brilliance.

Just as with natural diamonds, there are variations in gemstone quality among lab grown diamonds for sale. Though lab diamonds are made in controlled settings, each gemstone will have its own features in terms of quality. Our lab created diamonds receive IGI or GIA gradings to show their unique features.

Unlike diamond simulants, lab diamonds will not get cloudy as time goes on. Manufactured diamonds will not get cloudy, they will not turn yellow and they will not change color over time. That is because lab created diamonds are identical to natural diamonds in terms of chemical composition and optical properties.

Diamond simulants, such as cubic zirconia or moissanite, have different chemical compositions than natural or lab diamonds. These materials have a different chemical structure, making them behave differently when it comes to durability and appearance. Lab diamonds, on the other hand, are not diamond simulants. They are created in a laboratory setting and they have the same chemical composition as natural diamonds, making them equally brilliant and sturdy. 

Natural diamonds carry value due to their rarity. But lab grown diamonds also have value in terms of their beauty and durability. Lab diamonds bring long-lasting brilliance to all types of jewelry. Because lab diamonds have no intrinsic rarity, they are priced lower than natural diamonds.

Lab grown manufactured diamonds are perfect for many types of jewelry. As today’s manufacturing processes have evolved, larger and larger lab diamonds are available. Whether you’re searching for a 2 carat lab grown diamond engagement ring or matching half carat lab diamonds for a pair of earrings, there are many stones available. You can find the perfect lab diamond for earrings, necklaces, bracelets and more among our large selection of lab created loose diamonds.

As with any jewelry purchase, the choice to buy lab grown diamonds is a personal one. Lab diamonds offer affordability for many styles. Though all our diamonds at Blue Nile are ethically sourced, many people who prefer non-mined diamonds opt for lab grown diamonds. Both our natural and lab grown diamonds for sale feature ethical diamonds perfect for engagement rings and other jewelry.

Lab diamonds are most commonly made through one of two processes. They are either made through Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT) methods. These methods both produce stunning diamonds of many shapes and sizes.

Depending on your jewelry priorities, lab grown diamonds can be a great choice. They offer the same optical and chemical properties as natural diamonds, but for a lower price point.

Natural and lab manufactured diamonds are virtually indistinguishable, especially to the untrained and unaided eye. An expert jeweler may be able to tell the difference by looking at the gem’s inclusions and any special markings. But both natural and lab diamonds offer everlasting brilliance.

Yes, lab diamonds sparkle just like natural diamonds. This is because lab diamonds have the same optical and chemical qualities as natural diamonds. This makes them a popular choice for engagement rings and wedding bands.

Because diamonds made in laboratory settings can be produced at scale, they do not carry the same rarity as natural gems. This makes the price of lab diamonds much lower than natural ones. Lab created diamonds also offer additional benefits including ethical and environmental considerations.

Yes, jewelry insurance is available for lab diamonds and jewelry featuring these lab created gems. The jewelry insurance coverage will depend on the manmade diamond size, its setting and its 4Cs. For example, a high-quality 2 carat lab grown diamond set in platinum jewelry will likely receive more insurance coverage than a pair of 0.5 carat slightly included lab diamond stud earrings in white gold.

Lab created diamonds can be cleaned just as you’d clean natural diamonds. They are sturdy enough for ultrasonic cleaners and can also be cleaned with a gentler jewelry cleaning solution.

Yes, lab grown diamonds are just as durable as natural ones. They are a 10 on the Mohs scale, making them perfect for daily wear.

Lab grown diamonds, also known as lab made diamonds, are diamonds that have been created in a controlled laboratory setting. They bring the same durability and beauty that their natural counterparts are known for. The only difference is that lab created diamonds are expertly manufactured over the course of weeks or months in a controlled environment rather than formed naturally over the course of millennia deep in the earth.

We offer a wide selection of loose lab created diamonds for sale, with IGI and GIA reporting to help you choose the best fit. Our lab diamonds are available in shapes such as round, princess, emerald, Asscher, cushion, marquise, radiant, oval, pear and heart.

Just as with their natural counterparts, cultured diamonds are available in a variety of quality ratings. You can choose from flawless diamonds that are lab made or other clarity, cut and color ratings. To find the right fit, check the individual lab diamond’s grading report.

Lab grown diamonds are also known as manmade diamonds, cultured diamonds, lab created diamonds and engineered diamonds. Though they are sometimes called synthetic diamonds, this is not entirely true because though they are synthesized in a lab, lab diamonds have the same optical, chemical, and physical properties as a natural diamond. These gems are also not artificial diamonds because they have the same chemical structure as natural diamonds.

When buying lab diamonds, it’s important to choose jewelers you can trust. At Blue Nile, we are proud to uphold the highest standards for all our lab diamonds and jewelry with these gems, offering a wide selection of lab diamonds with the best diamond certification processes. We make buying a lab diamond easy and stress-free, with transparent reporting for every loose lab diamond and legendary customer service.
