Here’s why lab grown diamonds are the perfect choice for your next jewelry purchase.

What are Lab Grown Diamonds?

Lab grown diamonds are marvels of modern technology, created to replicate the natural process of diamond formation. The result is a diamond that shares the same physical and chemical properties as its mined counterpart, including its crystal structure, hardness, and brilliance. Lab grown diamonds are gaining popularity as a sustainable and affordable alternative to traditional mined diamonds.

How Are Lab Grown Diamonds Made?

Lab grown diamonds are made using advanced technology that replicates the natural process of diamond formation.

Creating lab grown diamonds is a meticulous process that involves several stages. It begins with selecting a diamond “seed,” which is then placed in a chamber where it is exposed to high pressure and temperature. Over several weeks or even months, carbon atoms bond to the seed, forming a new diamond. This lab grown diamond is then expertly cut and polished to reveal its inherent brilliance and fire, making it indistinguishable from a mined diamond to the naked eye.

Ethical and Sustainable Sourcing

One of the most compelling reasons to choose lab grown diamond jewelry is its ethical and sustainable origins. While lab grown diamonds are created in a matter of weeks, the process to create natural diamonds takes millions of years under the earth's crust.

Environmentally Friendly Practices

Mining natural diamonds often involves significant environmental disruption, including deforestation, habitat destruction, and the release of carbon emissions. Lab grown diamonds, on the other hand, are created in controlled environments using advanced technology, minimizing the ecological footprint. By choosing lab grown diamonds, you can enjoy their beauty while supporting environmentally responsible practices.

Conflict-Free Guarantee

Lab grown diamonds are inherently conflict-free. Unlike some mined diamonds, they are not associated with unethical practices such as forced labor or funding armed conflicts. This peace of mind allows you to wear your jewelry with pride, knowing that your purchase supports ethical sourcing and fair labor practices.

Cost-Effective Without Compromising Quality

When it comes to diamonds, quality and affordability often feel like opposing forces. Lab grown diamonds, however, offer the best of both worlds, allowing consumers to purchase a larger or higher quality diamond without exceeding their budget.

More Affordable Than Mined Diamonds

Lab grown diamonds typically cost considerably less than mined diamonds of comparable size and quality. This significant price difference makes it possible to purchase a larger or higher-quality stone within your budget, whether it’s for an engagement ring or a statement piece.

Getting More for Your Money

With lab grown diamonds, you don’t have to compromise on your dream design. You can afford a diamond with better cut, color, or clarity, maximizing the brilliance and beauty of your jewelry.

Identical in Quality and Appearance to Natural Diamonds

Despite the lower cost, lab created diamonds, also known as lab grown diamonds, are in no way inferior to mined diamonds.

Chemical and Physical Properties

Lab grown diamonds are chemically, physically, and optically identical to natural diamonds. They are made of pure carbon and exhibit the same hardness, brilliance, and fire as mined diamonds. Even professional gemologists need specialized equipment to differentiate between the two.

Certified Quality and Grading

Lab grown diamonds are graded by the same reputable organizations, such as the Gemological Institute of America(GIA) or International Gemological Institute(IGI), that certify natural diamonds. This ensures you’re getting a high-quality gem that meets stringent industry standards.

A Wide Range of Options and Customization

Lab grown diamonds provide endless possibilities for creating unique and personalized jewelry pieces.

Variety in Cuts and Colors

Whether you’re drawn to classic round diamonds, modern princess cuts, or vintage-inspired emerald cuts, lab grown diamonds come in all shapes and sizes. Additionally, they are available in a spectrum of colors, from traditional white to fancy hues like yellow, pink, and blue.

Perfect for Custom Jewelry

Lab grown diamonds are an excellent choice for custom jewelry designs. They allow you to create a one-of-a-kind piece that reflects your personal style, whether it’s an engagement ring, a pendant, or a pair of earrings. Customization ensures your jewelry is as unique as the person wearing it.

Supporting Innovation and Modern Technology

Lab grown diamonds, also known as lab diamonds, represent the cutting edge of jewelry-making technology and innovation.

The Science Behind Lab Grown Diamonds

These diamonds are created using advanced techniques like Chemical Vapor Deposition (CVD) or High-Pressure High-Temperature (HPHT) methods. These processes replicate the natural conditions under which diamonds form, resulting in stunning gems that are virtually indistinguishable from those mined from the earth.

A Testament to Modern Craftsmanship

Lab grown diamonds showcase the incredible advancements in modern jewelry craftsmanship. By choosing them, you’re not only embracing innovation but also supporting a more sustainable and forward-thinking approach to luxury.

Custom and Ethical Options for Discerning Buyers

Lab grown diamond jewelry offers DFW shoppers the chance to own exquisite, custom-designed pieces without compromising on ethics or quality. Lab grown diamonds offer a conflict-free assurance, extensive customization options, and consistent quality, making them an elegant and conscientious choice. Whether you’re celebrating a milestone or gifting a loved one, lab grown diamonds are an elegant and conscientious choice.

Sustainability and Carbon Footprint

Lab grown diamonds are not just a marvel of technology; they are also a beacon of sustainability. The process of creating lab grown diamonds requires significantly less energy and resources compared to traditional diamond mining. This means a much lower carbon footprint, as there is no need for large-scale excavation, deforestation, or habitat destruction. Additionally, lab grown diamonds do not contribute to the issue of “blood diamonds,” which are mined in conflict zones and sold to finance armed conflicts. By choosing lab grown diamonds, you are supporting a more ethical and environmentally friendly approach to luxury.

Lab-Grown Diamond Pricing - International Gem Society

Just like natural diamonds, lab-grown diamonds are priced according to the Four Cs: color, cut, clarity, and carat. However, lab-grown diamonds can cost 40 to 50% less than natural diamonds of similar size and quality. The cost difference is even greater for larger carat weights and fancy colored diamonds. Let's examine the major factors behind lab-grown diamond pricing.

The Business of Lab-Grown Diamonds

When first produced, lab-created or synthetic diamonds were far too costly to compete with natural diamonds as jewelry stones. However, as the technology and methods for lab production improved over the years, prices for synthetics have fallen. As prices decreased, consumer demand for a less expensive alternative to mined diamonds increased. This trend will likely continue.

As more lab-grown diamond producers enter the market, the increasing availability of lab-grown diamonds may keep their prices down. Indeed, the biggest price drop for lab-grown diamonds occurred after De Beers, the world's largest diamond mining company, announced their own line of lab-grown diamonds called Lightbox. By November , just six months after the introduction of these synthetic diamonds with a fixed rate per carat, the average discount for a one-carat synthetic diamond compared to a one-carat natural diamond grew to 42%. In January , the average discount for a one-carat synthetic diamond had been 29%.  

Carat Weight and Lab-Grown Diamond Pricing

Carat weight ranks as the important factor in lab-grown diamond pricing. Although variations in color and clarity quality can arise during lab production, synthetic diamonds typically have far fewer imperfections than mined diamonds. Both high pressure/high temperature (HPHT) and chemical vapor deposition (CVD) production processes, of course, offer a degree of quality control that doesn't exist over natural diamonds.

Exact Weights are More Common in Lab-Grown Diamonds

As a result of the control producers have over lab conditions, synthetics diamonds with exact weights, such as 1.0 or 2.0 carats, form more frequently than they do in nature. Natural diamonds will have more weight variations. Lab-grown diamonds weighing in at off-sizes will often cost slightly less, even though they may appear nearly identical to the naked eye.

Larger Carat Weights are More Common in Lab-Grown Diamonds

Large diamonds, weighing in at 2, 3, and 4 carats, are much more common in lab production than in nature. Producing stones in these sizes has become easier as technology has advanced. 

Unlike prices for natural diamonds, synthetic prices don't increase exponentially as carat weight increases. The price per carat of natural diamonds increases dramatically as carat weight increases because large natural diamonds are rarer than small natural diamonds. As a result, the price difference between natural and lab-made diamonds increases drastically for larger carat stones.

See the side-by-side images below for an example of an over 50% price difference in a 3.00 carat, H Color, VS1 Clarity, Excellent Cut round diamond.

Prices for larger carat synthetic diamonds are also dropping at a significantly greater rate than those for smaller carat weights. So far in , prices for synthetic diamonds between 3 and 3.99 carats have dropped 10.6%, and prices for those over 4 carats have dropped 8.7%. In , prices for synthetic diamonds between 3 and 3.99 carats had actually increased 1.2%. Prices for those over 4 carats had dropped just 0.3%. 

Color and Lab-Grown Diamond Pricing

Color has less impact on lab-grown diamond pricing than that of natural diamonds. This applies both to white or colorless as well as fancy colored diamonds.

Colorless Lab-Grown Diamonds

Colorless lab-grown diamonds are widely available at affordable prices. In a colorless diamond, any yellow tint detracts from its color grade and price. This occurs when nitrogen makes its way into the stone's chemical composition during its natural formation. This is far less likely to happen in a lab setting. A colorless stone with the highest color grade, D, is much more affordable as a synthetic than a mined stone.

Fancy Colored Lab-Grown Diamonds

Lab-created diamonds can come in a wide range of fancy colors. These are created by the deliberate introduction of elements, like nitrogen and boron, into the production process.

Natural diamonds in colors such as blue and pink are extremely rare and command very high prices. Lab-created diamonds in these colors cost thousands of dollars per carat less. For example, an average 1-ct, natural blue diamond with a medium tone can cost $200,000. In contrast, a synthetic 1-ct blue diamond can cost on average up to $8,500 per carat.

The per carat prices for natural fancy colored diamonds far exceed those for natural colorless diamonds. However, some lab-grown diamond producers, such as De Beers with their Lightbox line, offer their synthetic fancy colored and colorless diamonds with the same price per carat.

Cut and Lab-Grown Diamond Pricing

Diamond cutters can cut synthetic diamonds into any shape to suit the buyer's wishes. As with natural diamonds, rounds are the most popular cut. However, rounds are often the least expensive cut for synthetics. (In contrast, rounds are the most expensive cut for natural diamonds).

In recent years, lab-created diamonds with some fancy cuts have actually increased in price. From to , prices for oval cuts increased 5.2%, emerald cuts increased 3%, and radiant cuts increased 0.8%. Currently, consumer demand for these cuts exceeds the supply, but this may change as trends and styles change.

Clarity and Lab-Grown Diamond Pricing

As with natural diamonds, any inclusions or imperfections in a lab-grown diamond that affect its clarity grade will negatively impact its price.

Lab-grown diamonds may contain inclusions from the various substances used to facilitate their growth. These may result in visible imperfections and dark spots.

Grading Reports and Lab-Grown Diamond Pricing

Currently, many lab-grown diamonds on the market will come with a grading report from the International Gemological Institute (IGI) or the Gemological Institute of America (GIA). Both institutions will grade lab-grown diamonds just like natural diamonds, although the GIA only started to give full reports in . Previously, the GIA only gave grade ranges, not specific grades, to lab-grown diamonds.

Please note, although the term "certificate" is used very frequently, especially by diamond vendors, professional gemologists should avoid using this term. "Certificate" implies "certification," an independent, external, objective review. Diamond grading, although it can adhere to professional standards, is nevertheless an opinion. The more appropriate term is "grading report."

Grading reports will include the diamond's carat weight and grades for color, cut, and clarity. This makes it easy to compare the stone to other graded diamonds.

Most synthetics receive grades from the IGI. This is because a GIA grading report is more costly, and the price of a GIA-graded diamond could reflect that.
