What is LAB GROWN DIAMONDS?


An inspired choice- Lab Grown Diamonds (LGD) uses a socially and ecologically mindful production of diamonds without destroying millions of tons of land. It uses CVD (Carbon Vapor Deposit) and/or HPHT (High-Pressure High Temperature) processes to produce rough diamonds in manufacturing setup, like all other manufacturing plants.


All Lab Grown Diamonds are Type II2 diamonds. Type II2 diamonds are the most valued and purest type of diamonds in the world. In the earth mined diamonds, only 2 to 3% of all production is Type II2 diamonds. The Cullinan and Koh-I-Noor diamond in the Crown Jewel of Queen of England are both Type II2 diamonds. Its crystal structure contains little to no nitrogen atoms. White stones are exceptionally colorless while fancy colored diamonds are often found with a purple, blue or pink tone.


Lab Grown Diamond is a genuine diamond that is man-made in a lab. Many times, they are called synthetic diamond which is theoretically correct but is confusing and misleading. It is far different than CZ (Cubic Zirconia), Moissanite or Sarkowsky Diamonds. In fact, FTC has acknowledged that the term, Synthetic Diamond, is misleading and agreed that the term, "Laboratory Grown" or "Cultured" or "Laboratory Created Diamonds" could be used to alleviate such confusion.. LGDs are in fact the real deal sharing the same diamond crystal and earth mined diamonds. Advanced technology replicates the similar conditions which creates diamonds beneath the earth. Canadian diamonds are mined in Canada, Australian Diamonds in Australia, African diamond in Africa, Russian diamond in Russia and so on. Similarly, LGD is made in Lab Factory.


LGD can be manufacture in two different ways. One method is High-pressure High temperature (known as HPHT). This is when engineers make something of a diamond/carbon soup and then using high pressure and high temperature they can create single diamond crystals. The second way is via chemical vapor deposition (known as CVD). This process takes a tiny seed of diamond crystal and then grows the diamond layer by layer in a chamber.


LGD is a real diamond in every sense: Chemically, Physically, Optically and Atomically; the only difference being their origin-underground or in a lab. For example, consider a rose grown outdoor in nature versus one grown in a greenhouse. Is the one grown in a greenhouse any less of a rose than one grown outdoor? Is it any less beautiful or fragrant? Similarly, Lab grown diamonds are the same as the earth mined diamonds.

Comparison of Mined Diamonds with LGD Diamonds

Let's break it down. Here is a comparison chart of the properties of mined and LGD diamonds:

Physical Properties LGD Mined Diamonds Cubic Zirconia-CZ
Hardness 10 10 8.25
Refractive Index 2.42 2.42 2.13
Specific Gravity 3.52 3.52 5.7
Dispersion 0.44 0.44 0.066
Thermal Conductivity 2000 W/m/K (High conductivity) 2000 W/m/K (High conductivity) Very low conductivity
Chemical Composition C C ZrO2
Optical Transparency Deep UV-Far IR Deep UV-Far IR Near UV-mid-IR
Crystalline Structure Cubic Cubic Cubic

LGDs are cut, polished and graded exactly in the same way and with the same standards of 4C's as earth-mined diamonds. The larger diamonds come with certification by leading independent gemological labs like International Gemological Institute (IGI).

4C's of Diamond

Until the middle of the twentieth century, there was no agreed-upon standard by which diamonds could be judged. GIA created the first, and now globally accepted standard for describing diamonds: Color, Clarity, Cut and Carat Weight. Today, the 4Cs of Diamond Quality is the universal method for assessing the quality of any diamond, anywhere in the world. The creation of the Diamond 4Cs meant two very important things: diamond quality could be communicated in a universal language, and diamond customers could now know exactly what they were about to purchase.

Cut

The cut of a diamond refers not to its shape, but to the balance of proportion, symmetry and polish achieved by the diamond cutter. The extent of how well the diamond is cut is directly related to the diamond’s overall beauty. When a diamond has been correctly cut, the diamond’s ability to reflect and refract light is greatly enhanced. By understanding the way that light moves through diamond crystals, modern diamond cutters have established a specific set of proportions and angles that are known to harness the diamond’s internal brilliance and to show it in its best light.

Ideal Cut

An Ideal Cut Diamond is a round, brilliant, or princess cut diamond that is cut to ideal proportions and angles, and has excellent polish and symmetry ratings. An Ideal Cut Diamond is perfectly proportioned to refract light, producing that fire and brilliance up through to the table and crown. James Allen offers a nice selection of Ideal Cut Diamonds know at True HeartsTM

GIA, considered to be one of the most respected laboratories for grading natural diamonds, uses the following language on their certificates to grade cut for round diamonds: Excellent, Very Good, Good, Fair, Poor. A GIA Excellent cut will be listed as either Ideal or Super Ideal on the Brilliant Earth site. Brilliant Earth uses specific diamond characteristics, such as cut grade, polish, and symmetry to distinguish between Ideal and Super Ideal. If a cut grade is not available from a grading laboratory, such as for fancy shaped diamonds, Brilliant Earth combines the characteristics above along with depth, table, secondary measurements, and subjective factors to assess the cut grade of the diamond.

Color

Color refers to the natural body color of a diamond and not to the reflection of spectral colors that flash when a diamond moves. Most diamonds naturally exhibit slight hints of yellow, brown, or gray. This color is caused by natural trace elements of nitrogen that were present when the diamond formed under the Earth’s crust. The less color a diamond exhibits, the higher the rarity, and therefore the higher the value.

Diamond Color

Color of a diamond is a result of diamond’s composition and does not change with time. Colorless diamonds allow light to travel through them as compared to the colored diamonds. These diamonds also emit more fire and sparkle. The process, through which a diamond is formed, is the deciding factor for its color. The whiter the diamond is the higher value it will have. For grading the color of diamonds, jewelers refer to GIA’s color scale that starts the rating with D for the colorless diamonds and grows up to Z as the traces of light yellow or brown color are found in the diamond. Diamonds graded from D to F are amongst the most desirable and valuable stones. These diamonds are a delight for the diamond lovers. Nevertheless, if you have a low budget, you can also find good diamonds with lower grades. These diamonds are not exactly colorless but show no color to untrained eye.

Clarity

Clarity refers to how clean or clear the diamond is with respect to natural microscopic characteristics that were trapped within or on the diamond while it was forming. Internal characteristics are known as inclusions, and characteristics on the surface of the gem are known as blemishes. Inclusions may be crystals of a foreign material or structural imperfections such as tiny cracks, known as feathers, which can appear whitish or cloudy.

Diamond Clarity

Diamond clarity means finding out characteristics of a diamond, including the blemishes and inclusions. If you consider the pressure that a diamond is created, and that they are not produced in sterile laboratory, you will be not be surprised to find that most of these diamonds are not free of flaws. Usually there are two kinds of flaws found in diamonds – blemishes and inclusions. Inclusions are naturally occurring internal flaws that are found in diamonds including cracks, air bubbles, and mineral. However, most blemishes occur at the time of cutting process.

The diamonds that have less blemishes and inclusions are considered valuable as compared to those that have more. GIA certificates consist of a diamonds inclusion plot, as there is no similarity between two diamonds. The plot of the GIA certificate ensures the worth of the diamond you are planning to buy. It lets you have the assurance that the diamond you are receiving is the one you have paid for. If you are in a fix about what clarity grade you should choose, flawless is the best and rarest clarity grade. Move the slider to view examples of different diamond clarity grades.

Carat

Carat (ct.) refers to the unique unit of weight measurement used exclusively to weigh gems and diamonds. Carat weight is often confused with visual size even though it is actually a measurement of weight. Depending on the shape and type of gemstone being weighed, the weight will visually show itself differently. For example, a 1.00 ct. round diamond will measure around 6.5mm, and a 1.00 ct. round sapphire will measure around 6.0mm. This is due to the varying density of different gemstones.

Ring Type

One advantage of buying your engagement ring from an online jeweler is the expanded access you get to ring styles. At Brilliant Earth, we offer almost every ring style imaginable – and if we don’t have a style you want, we can custom design a ring for you. To choose the perfect ring, consider what fits her lifestyle and personality best. In addition to your budget, her personal style and her daily activities are the main considerations that should guide your selection of a setting. Here are recommendations that match personality traits with various styles of engagement rings:

Solitaire Engagement Rings

A solitaire ring setting features a single stone, typically a diamond with a plain mounting (usually four or six prongs). Solitaires are one of the most popular engagement ring settings. Their appeal is in their elegance, simplicity, and timelessness. Solitaire engagement rings come in a variety of sizes and styles. Some have narrower bands which have the effect of making a smaller diamond appear larger, and compliment small fingers. Others have thicker bands which allow for more options in the way the diamond is set. Many solitaire rings have ring guards (or rings wraps) which frame the center diamond, making it appear more prominent.

Shop Engagement Rings

Halo Engagement Rings

Halo engagement ring settings feature a center gemstone surrounded by smaller, micro pave diamonds. The smaller diamonds give the appearance of size and volume to the center stone, adding to the ring’s overall sparkle. Traditional halo engagement rings are a more modern take on the classic solitaire ring, while vintage-style halo rings focus on the micro pave and milgrain detailing along the band. Halo engagement rings come in all shapes and sizes of center stones. Some feature round stones, asscher-cut diamonds, pear-shaped and oval diamonds. Halo rings often feature colored gemstones, like blue sapphires or red rubies.

Pave Engagement Rings

A pavé engagement ring is encrusted with very small diamonds all along the band to give the appearance of a solid diamond surface. Because pave-set diamonds use only tiny beads or prongs to hold them in place, very little of the metal band shows through and the diamonds appear to be free-standing. Pave settings can either go around the whole band (full pave) or stop halfway around it (half pave). Micro pave rings are even more delicate and intricate than regular pave settings. The individual stones are so small that they appear to blend together and create extraordinary fire. Typically, round brilliant or princess cut diamonds are used as center stones in pave engagement rings. Most center stones are prong-set, basket-set or bezel-set.

Shop Engagement Rings

Sidestone Engagement Rings

Sidestone engagement ring settings provide a perfect complement to a center stone and typically consist of a center diamond flanked by two or more smaller-sized side diamonds. Because sidestones add size and brilliance to the center diamond, they make the overall appearance of the engagement ring more impressive and radiant. When it comes to selecting a center diamond for an engagement ring with side stones, round brilliant or princess cut diamonds are typically chosen, although most diamond shapes can be used.

Vintage Engagement Rings

Vintage and antique-style engagement rings offer the beauty and intricate craftsmanship of vintage rings with the sturdy and lasting design techniques of modern engagement rings. Vintage-style engagement ring designs often draw inspiration from various time periods and contain diamonds with modern diamond cuts, which maximize fire, brilliance, and light reflective properties. James Allen offers a variety of vintage and antique-style engagement rings in yellow gold, white-gold and platinum. Most diamond cuts are used as center stones for vintage rings. In vintage rings, center stones are usually prong-set, basket-set or bezel-set.

Setting Types

We offer a broad range of settings, but we’ll help you narrow down the options by taking into account the style preferences, lifestyle, and personality of your partner.

Prong

Prongs are the most traditional setting technique. Prongs allow for maximum exposure of the diamond and minimize the presence of metal (gold or platinum). In turn, more light is able to pass through the diamond, which only adds to its brilliance.

Shop Engagement Rings

Bezel

This setting style, primarily known for its simplicity and durability, encases the surrounding outer edge of the diamond in a fine frame of metal (gold or platinum). When using white gold or platinum it can often give the diamond a larger appearance. The bezel setting is a versatile one because it can accommodate every diamond shape.

Shop Engagement Rings

Tension

A tension setting is a modern and beautiful method of setting a diamond into a ring. In tension-set rings, the diamond is essentially "squeezed" into a small groove that is cut into the tension mounting. The mountings are manufactured using precious metals that are especially hardened to grip the diamond without the necessity of prongs. The settings are designed to be very secure.

Shop Engagement Rings

Channel

Channel settings are a loved for their brilliance and durability. With this setting, small diamonds (usually round or princess-cut) are set deep into the metal band, thus creating a “channel” which holds the diamonds. The small diamonds are very secure because they are embedded into the metal, making it very difficult for them to fall out. For this reason, channel settings are a particularly good choice for people who work with their hands.

Shop Engagement Rings

Twist

Twist settings are becoming more and more popular among couples looking to buy an engagement ring. In this setting, the metal band is shaped and turned to create a crisscrossed effect. The result is a unique look that is as complex as it is delicate.

Shop Engagement Rings

Bar

As the name suggests, the bar setting is characterized by two metal bars that hold the diamond in place. The bar setting is a sleek and modern look that makes a bold statement. This setting is also showcases the center diamond beautifully, which allows more light to enter the diamond and increases the diamond’s brilliance.

Metals

Choosing the right metal for an engagement ring is a crucial part of the ring-design process. Once you know a bit about the basics of ring metals, deciding on a metal is a rewarding and simple process. Choosing between white gold, yellow gold, or platinum is as much as matter of personal preference as it is of budget. Before you make a final decision, it is worth weighing the pros and cons of the various types of engagement ring metals.

Instead of engraving your wedding date, you might choose to engrave the date you met, or the date of some other special relationship milestone. Or you might choose to engrave your beloved’s first or middle name in the interior or your ring, and yours in his.

Saying and Quotes

Occasionally you will run across a quote that expresses how you feel perfectly. Sometimes the best engravings are simple expressions such as, “I do,” “You and I,” or “All my love.” Depending on the size of your ring, you may be able to request a longer saying or quote, such as, “Who, being loved, is poor?” by Oscar Wilde or, “Love conquers all,” by Virgil.
