Lab Created Diamonds

Lab created diamonds, also known as cultured diamonds or synthetic diamonds, or CVD diamonds, are grown in highly controlled laboratory environments using advanced technological processes that duplicate the conditions under which diamonds naturally develop when they form in the mantle, beneath the Earth’s crust. Since they are made of the same material as natural diamonds, they exhibit the same optical and chemical properties. So a lab diamond can only be distinguished from natural diamonds using specialized equipment that can detect the minor differences in trace elements and crystal growth. It's not easy to find the difference both man-made diamons and natural diamonds by naked eye.

Whether you call them lab grown diamonds, lab created diamonds, synthetic diamonds or man made diamonds, they’re all one and the same. Lab grown diamonds are carbon diamonds that have been grown in a laboratory, much like flowers grown in a greenhouse. They are as real as diamonds pulled from the earth, and they sparkle just as brilliantly. The big difference? Lab grown diamonds aren’t associated with the unethical practices that are inherent with mined diamonds. We’re talking about earth displacement, ocean dredging and habitat destruction. If you love diamonds, go guilt free. Get the sparkle you want without the high price tag and unethical concerns.

Like mined diamonds, lab created diamonds are made of carbon. Although they’re exactly the same optically, chemically and physically, they’re created very differently. While diamonds pulled from the earth are created over millions of years under intense heat and pressure, lab created diamonds are grown fairly quickly in a lab from a single carbon seed. Using advanced technology—either Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT)—the carbon seed slowly forms into a crystalline structure. No two diamonds turn out exactly the same, just as no two mined diamonds are the same. Each one differs immensely when graded on the 4C’s criteria: cut, color, clarity and carat. Lab created diamonds are real diamonds. Both man made diamonds and mined diamonds are made of a crystallized carbon structure. So from their appearance to their chemical makeup, they’re exactly the same. Lab created diamonds not so much higher than earth-mined diamonds, you don't need to worry to buy “conflict free” diamonds.

Natural and lab grown diamonds have thermal conductivity properties that differentiate them from cubic zirconia with a handheld diamond tester. Some lab diamonds, along with some natural colored diamonds, may be mistakenly identified as moissanites when using certain diamond testers due to similarity in their electrical conductivity. However, gemologists can typically distinguish between diamond and moissanite due to their differing refractive properties, with moissanites being double refractive and diamonds being single refractive.

Our lab created diamonds exhibit the same fire, scintillation, and sparkle as natural diamonds. Using a jewelry loupe, man made diamonds are nearly impossible to differentiate from natural diamonds. Synthetic diamonds are more affordable than natural diamonds of comparable size and quality, you can save your budget to prefered to cultured diamons. Like natural diamonds, each piece is unique. Lab created diamonds may contain minor internal or surface inclusions. If you want to have factory wholesale prices of lab created diamonds, please feel free to contact us any time.

The cut of the lab created diamond is a measure of the quality of the shape, geometry, and finish of diamond gemstone. Only round brilliant diamonds receive formal cut grades on a scale from ldeal (the best) to Poor. We in uncompromising on cut quality to ensure all of our diamonds have optimal brightness, fire scinillation, andmaximum light performance.

Clarity is a measurement of how many blemishes or inclusions are present in the Lab-diamond, which can be eitherdefects in the diamond crystal or microscopic foreign particles within the diamond. The lower the darity of a diamond, the more imperfections in the diamond. Clarity is graded on a range from Internally Rawless to Induded

A perfect diamond, with no impurities and no defects, is completely colorless. Impurities such as nitrogen causeundesirable yellow or brown tones in the diamond Color is graded on a range of letters from D to Z

The carat weight of a Lab-diamond is a measurement of its weight One carat is exactly one- fifth of a gram (0.20 g).When a diamond is properly cut the carat weight defines the size of the diamond, and larger diamonds tend to be more expensive.

Responsible Choice:

When you pick up two pieces on diamonds, one manmade, one mined, you will never be able to tell the difference. The two are identical to the naked eye. They also have the same chemical composition.The most intriguing thing about manmade diamonds is the process in which they are made. These diamonds are created by using either the HPHT or the CVD method. Either way, the result is a diamond with the similar properties as the natural diamond but with dissimilar and discernible crystal patterns.

When diamonds are available at a lesser price, why wait for the right occasion? As mentioned above, Lab diamonds have the same chemical composition as mined diamonds, and they are a cheaper alternative. These diamonds entice diamond lovers to purchase more often. These 100% conflict-free diamonds resonate well with the conscientious buyers. Lab grown diamonds are spectacular to look at. They are diamonds after all. They have the same chemical composition and optical properties as mined diamonds.

Certified Diamonds:

The International Gemmological Institute (IGI) is a reputable gemmological lab that grades and certifies diamonds. IGI strictly adheres to the international standards of diamond certification. IGI reports gives an accurate assessment of a diamond's cut, color, clarity and carat. In the gemological world, an authentic IGI certificate is hallmark of trust and confidence across countries and marketplaces.

Reliable Price:

Mined diamonds are no longer the only choice for fine diamond jewellery. Lab grown diamonds are becoming more and more popular. Mined diamonds have always been associated with wealth and status. Lab grown diamonds are seen as a sustainable alternative. Due to this, they hold a special appeal for the millennials. While the millennials are extremely responsible buyers, they are also value consumers. And, the price point of lab grown diamonds makes it an ideal choice. This is one more reason why more and more millennials are keen on purchasing lab grown diamonds. A lab diamond with the exact same color, cut, carat weight, and clarity characteristics than a natural diamond, can be 30-50% cheaper. You get more for your money if you decide to go for a manmade option.

How are HPHT Diamonds Made?

The HPHT method is the original method of creating lab-grown diamonds. During HPHT, diamonds are made in a lab by replicating the high-pressure, high-temperature conditions that form diamonds underground in the Earth.

Gem quality HPHT diamonds were introduced in the 1950s. Outside of growing diamonds, the HPHT process can also be used to enhance the color of diamonds to make them colorless, pink, green, blue, or yellow.

To grow an HPHT diamond, a small diamond seed (a very tiny diamond) is placed in carbon, the element that diamonds are made of. The diamond seed is exposed to extreme heat and pressure, replicating the way diamonds are naturally grown underground by the earth. The diamond seed is exposed to temperatures of over 2,000 degrees Fahrenheit and pressure of about 1.5 million PSI (pounds per square inch). The carbon melts and forms a diamond around the seed. It is then cooled and the diamond is formed.

HPHT diamonds are more likely to have a yellowish hue because they are exposed to nitrogen while forming. They also tend to have darker inclusions, which are metallic. These metallic inclusions can help scientists identify them as lab-grown because naturally formed diamonds rarely capture metals during formation.

The metallic inclusions in HPHT diamonds can make the stones magnetic. This is another way to tell if a diamond is lab-grown – natural diamonds are not magnetic. A 2012 study revealed that over half of the HPHT diamonds tested registered a detectable magnetic response.

How Are CVD Diamonds Made?

The CVD method was created in the 1980s, making it newer than the HPHT method. The CVD method imitates how diamonds form in interstellar gas clouds. The CVD method uses less pressure than the HPHT method as well as smaller machines.

The CVD method places a diamond seed in a vacuum chamber. This chamber becomes filled with carbon-rich gases and is heated to nearly 1500 degrees Fahrenheit. The gas turns into plasma from these extremely high temperatures, causing the release of carbon pieces. These carbon pieces become layered onto the diamond seed, which grows the diamond.

The CVD process produces Type IIA diamonds, which are extremely rare for naturally occurring diamonds. This can help scientists determine if a diamond is lab-grown or earth grown. Type IIA diamonds are the most chemically pure diamonds – they lack nitrogen and/or boron impurities, unlike HPHT diamonds that are exposed to nitrogen. CVD diamonds are not magnetic like HPHT diamonds can be.

Which method is better?

You will not be able to tell the difference between a CVD and HPHT diamond with the naked eye. Both methods can create a beautiful, sparkling diamond. Both the CVD method and the HPHT method will create a real diamond that is optically, chemically, and physically identical to earth-grown diamonds.

Are lab-grown diamonds fake diamonds?

​Lab-grown diamonds are REAL diamonds - the only difference between lab-grown diamonds and earth-grown diamonds is their origin.

Are lab-grown diamonds graded differently?

Lab-grown diamonds are graded the same as earth-grown diamonds. Each report will include details on the stone's color, clarity, cut, and carat weight.

Do lab-grown diamonds have resale value?

Since lab-grown diamonds are relatively new to the market, it isn't really certain whether or not they will have resale value. We recommend viewing lab-grown diamond jewelry as a gift rather than an investment.

Do lab-grown diamonds get cloudy over time?

No - because they are chemically, physically, and optically natural diamonds, they will retain their beauty.

Do lab-created diamonds test as real?

Yes, your lab-grown diamond will test as real with a diamond tester.
