The diamonds are all Created in America with masterful craftsmanship. Diamond Foundry are truly setting the standard for diamonds. This is the very same company that successfully made a case for lab grown diamonds to be acknowledged as diamonds, as per the FTC’s July 2018 ruling.

Just because the diamonds are grown in a lab doesn’t mean they aren’t all unique. Each diamond forms in its own way, with the same one-of-a-kind inclusions and unique growth patterns found in earth mined diamonds. No two lab grown diamonds from Diamond Foundry are alike. Each is unique to the core.Diamond Foundry Seal

Diamond Foundry diamonds are each certified with their unique gemological ID. A GIA gemologist does the grading and issues the Diamond Foundry branded grading certificates.

The diamonds are hot-forged above ground without the vast environmental impact associated with mining.

Diamond Foundry uses solar renewable energy.

Creating the Diamond Foundry diamonds even takes less energy than extracting them from earth via industrial mining– and the energy used is all renewable.

Diamond Foundry is the world’s first diamond producer certified to be 100% carbon neutral.

About Diamond Foundry

Diamond Foundry cuts their diamonds to perfect proportions to reveal a superior, striking diamond. They know that it is the quality of the cut that delivers the much desired brilliance of a diamond. So there’s no point in offering sub par stones after going to all that trouble.

The Diamond Foundry cutting studios and polishing workshops are filled with artisans and craftsmen. The diamonds are inspected no less than 1,300 times from the time the rough stone emerges to when it is in a finished ring.

In case you didn’t already know it is less than 1% of all diamonds on the market that can meet this level of high quality.

But that’s not all!

Lab Grown Diamonds Explained

Clearing up the naming convention

Lab grown diamonds have been referred to as synthetic diamonds, man made diamonds, artificial diamonds, manufactured diamonds, and cultured diamonds. In July 2018 the FTC ruled that the terms lab grown diamonds, man made diamonds, and foundry diamonds are descriptors to be used to qualify the term cultured diamond. The term synthetic is not to be used in reference to lab grown diamonds as per the FTC ruling. Up to now GIA has been using the term synthetics when referring to lab grown diamonds, so it remains to be seen how soon they will update their synthetic diamond grading terminology.

I just want to point out that it’s  also important to not confuse the term diamond simulant with the term lab grown diamond.

Lab grown diamonds are different to simulants. A simulant diamond is a stone that only appears similar to a diamond but is nothing like a diamond in any other aspects such as its molecular make up.

For example a piece of glass can be cut like a diamond. This would make that piece of glass a diamond simulant. Other simulants include many crystals, and other gems that have a clear appearance, such as moisonite and cubic zircon. Simulants are not all lab grown. Some are natural mined minerals and some are created in a laboratory. The term simulant is a very generic term and is not the correct descriptor when referring to lab grown diamonds.

Given the rarity and value of diamonds, it’s not surprising that some would seek ways to replicate their beauty. While people have experimented with diamond growing technology for more than a century, it has only been in the last decade that we’ve been able to perfect the science of creating gem-quality man made diamonds in a modern-day lab. Numerous claims of diamond synthesis were documented between 1879 and 1928. In recent years, laboratory-grown or synthetic diamonds have become more common, more advanced, and harder to differentiate from mined diamonds.

About certification

IGI laboratories have been busy. This new influx of lab grown diamonds to grade is a result of the rapidly growing demand. This has been good for the IGI network in more ways than one. The increase in business is always a good thing, but it has also resulted in IGI asserting its place as the foremost laboratory for lab grown diamonds. Jewelers far and wide are now reporting that IGI has shaken off its former reputation for sub par work or inconsistency. The diamonds being graded by IGI whether mined naturals or lab grown, reflect a rigorous methodology and strict standards.

How Lab Grown Diamonds Are Made

A lab grown diamond is the result of a technological process, as opposed to the geological process that creates natural diamonds. Lab grown diamonds have essentially the same chemical composition, crystal structure, optical, and physical properties of diamonds found in nature. Most lab grown diamonds are categorized as either high-pressure, high-temperature (HPHT) or chemical vapor deposition (CVD) diamonds, depending on the method of their production. Since HPHT and CVD diamonds are virtually identical to natural diamonds, differences only become clear when they are analyzed in a gem laboratory. The properties of lab grown diamonds depends on the details of the manufacturing processes; however, some lab grown diamonds (whether formed by HPHT or CVD) have properties such as hardness, thermal conductivity and electron mobility that are superior to those of most naturally formed diamonds.

This 1.15 Ct. | Round Cut | D Color | VS1 Clarity lab grown diamond, also known as a created diamond, man made diamond or synthetic diamond measures 6.72mm L x 6.74mm W x 4.13mm H. The grading report has been issued by an IGI laboratory. It is chemically, physically & optically identical to a mined diamond of matching specifications. It is priced 40% lower than a mined diamond of equal specifications.  view price
Emerald cut pink man made diamond.
1.22 Ct. | Emerald Cut | Crocus Pink Color | VS2 Clarity. Lab grown pink diamonds are quite popular due to the difficulty in obtaining natural pink diamonds. Lab grown pink diamonds are not cheap either, but they are vastly lower in price when compared to mined pink diamonds. Fancy cuts often show off the color of the diamond more effectively than the round brilliant cut which makes this emerald cut a good choice. This diamond is priced at least 90% lower than a mined diamond of equal specifications. view price

Some Facts About Lab Grown Diamonds

If you are looking for a lab grown diamond I probably don’t have to sell you on the idea, but here are a few additional facts about lab grown diamonds which will make this decision even easier.

1. Eco-friendly- This is the first point that everyone is aware of and probably its biggest selling point. Lab created diamonds are sustainable diamonds, they are by all definitions “ethical”. The way the are grown with minimum environmental impact makes them a good choice in this regard. By choosing a grown diamond over an earth-mined diamond you’re doing your part to reduce harmful impact on the environment . Going green is on the forefront of many people’s minds and lab grown diamonds is one way of reducing the impact of mining.

2. Synthetic, Not Fake- Synthetic gems have been available for a long time. Natural gems and synthetic gems both have their place in the jewelry industry. Lab grown or what’s also been called man made diamonds are not fake diamonds. They are both made up of the same molecular structure. This similarity also means that a grading report should always accompany the sale whether it be a lab grown diamond or a mined diamond.

3. HPHT and CVD – These are the two main methods used for growing diamonds.HPHT (High-Pressure High Temperature) is a process in which the stone grows out of a diamond seed under controlled conditions. As you might have guessed by now those conditions include high temperature and high pressure. Natural diamonds formed this way so it was only a matter of time before the process was fine tuned to make this possible in a lab. The second process, CVD (Chemical Vapor Deposition) is a more recent development. This process involves a chamber filled with carbon-rich vapor.

4.Identical – Without expensive cutting edge laboratory equipment there is no way to tell the difference between a lab grown diamond and a mined diamond.

5. Diamond is one of the hardest known materials. This makes it useful in construction, nuclear engineering, and medicine so Diamond is one of the hardest known materials.

6. Lab created diamonds are a sustainable resource:-According to current industry predictions, the supply of mined diamonds is expected to decline in years to come, as diamonds from known sources pop out. But demand for diamond is expected to continue to expand, not only for jewelry but for different industries. It will not only sustain jobs in jewelry industry but also in other industrial and high tech fields where diamonds are needed.

7.Guaranteed origin:-AIDIA lab-grown diamonds are created so that you know where are the diamonds extracted and from where it is sourced. When the diamonds are extracted for cutting, faceting, and polishing; AIDIA uses highly trained diamonds to bring out lab-grown beauties to a sparkling finish.

8.Resale Value: some of the people have a misconception that lab created diamond do not have any resale value. This concept is incorrect. Lab created diamonds do have a resale value in the same way mined diamonds have a resale value. Much of the added value of obtaining lab certification and marketing costs will inevitably result in a reduction in resale value with both natural mined diamonds and lab grown diamonds.

9. An enduring treasure. Lab grown diamonds never fade, do not get cloudy nor do they change color over time: They have physical and optical features which are identical to mined diamonds. Sure an occasional polish is a good idea, but the diamond itself is not going to change in any way whatsoever. As they say, diamonds are forever.

How common are lab grown diamonds?

Diamond Production Graph

The past decade has seen an increase in the production of lab grown diamonds. This is a direct result of the advances in the technology used to grow diamonds. The amount of diamonds that are produced is still limited by time. It still takes about three weeks to grow a diamond in a lab. We aren’t going to see laboratory grown diamonds overtake mined diamonds any time soon. The inventory of lab grown diamonds will remain much smaller than the inventory of mined diamonds. The amount of natural diamonds mined in one year is close to 200 times the amount of lab grown diamonds produced in the same year.
