"They're both diamonds, they have the same chemical properties, the same physical properties."

— John King, Chief Quality Officer of the Gemological Institute of America (GIA)

Rather than selling diamonds dug out of massive holes in the Earth, Ada Diamonds proudly offers only laboratory-grown diamonds in our fine jewelry. Ada's diamonds are sustainably cultured by recreating the extreme pressure and temperature required to convert carbon into a diamond crystal structure.

Ada's diamonds have the same exact same crystal structure, chemical composition, optical properties, and physical properties as a mined diamond - carbon atoms arranged in a cubic crystal structure. Ada's diamonds are not fake, simulants, or cheap substitutes. Ada's diamonds are the hardest material on Earth and are approximately 10 times harder than sapphire and 100 times harder than cubic zirconia.

The process to grow diamonds is one of the most precise and difficult manufacturing techniques that humans have ever achieved. It took almost 60 years of effort to develop the precision to grow gemstone quality diamonds larger than one carat. 

Ada's diamond gemstones are graded on the exact same criteria as mined diamonds (the Four Cs), by the exact same independent gemological laboratories that grade Earth-extracted diamonds. Compared to mined diamonds, Ada's diamonds have fewer impurities and fewer defects in the crystal structure. Our white diamonds are greater than 99.99999% pure carbon. This makes Ada Diamonds whiter, brighter, and stronger than the vast majority of mined diamonds. 


Dispelling Common Misconceptions

MISCONCEPTION #1: LAB DIAMONDS ARE CHEAPER THAN MINED DIAMONDS 

This is the most common misconception and is completely false. De Beers self-reported costs to mine diamonds was $104 per carat (for rough diamonds) in 2015. The marginal cost to grow each diamond in a laboratory is many times the cost for De Beers and other mining operations to dig diamonds out of the earth, even if you ignore the fixed costs of the machinery required to culture diamonds in a lab. The costs to cut, polish, and grade diamonds is exactly the same, regardless of the origin: grown or mined.

MISCONCEPTION #2: LAB DIAMONDS ARE ALL COLORLESS AND FLAWLESS

The process to grow diamonds in a laboratory is very similar to the geological growth process. The same types of inclusions and imperfections present in mined diamonds can also occur in lab diamonds. If the diamond crystal grows too fast, there can be minuscule cracks (feathers) in the diamond. There can also be small inclusions of trace elements or other growth defects that cause the diamond to be near-colorless or slightly included. Lab diamonds are independently graded on the exact same criteria as mined diamonds by the exact same independent gemological laboratories that also grade mined diamonds.

MISCONCEPTION #3: THEY ARE GOING TO FLOOD THE MARKET

There are approximately 25 million carats of diamond gemstones that are mined, cut, and polished every year, with billions of carats more in existing mines. De Beers estimates it's current diamond reserves at 479.7 million carats.  To build production facilities large enough to generate one percent of the current mined supply would take hundreds of millions of dollars of capital expenditure to build the facility and tens of millions of dollars a year to run the facility. It will take many years before lab diamonds are anything but an extremely small portion of the total diamond market.

MISCONCEPTION #4: THEY REDUCE THE VALUE OF MINED DIAMONDS 

This misconception hinges on three incorrect assumptions:

  1. Diamonds are rare (see below)
  2. There will be enough diamonds grown in a labs around the world to reduce that rarity (see Misconception #3)
  3. That it is cheaper to grow diamonds than it is to mine them (see Misconception #1).

While mined fancy colored diamonds and large investment grade diamonds are quite rare, there are currently over one billion carats of diamond gemstones owned globally. Experts estimate that the Baby Boomer Generation in the United States owns over 500 million carats of diamond gemstones which will be inherited or resold in the next few decades. Ada believes the much larger threat to the value of mined diamonds is the recycling and resale of previously mined diamonds, a space that De Beers recently entered
