Lab Diamond Engagement Rings Alchemized
from Thin Air

Aether Lab Diamonds are crafted using carbon extracted from the atmosphere, each carat positively impacts our climate.

The Rarest Diamond
On The Planet

Aether captures carbon from the atmosphere that is otherwise contributing to global warming, and transforms it into the highest quality, and rarest diamonds on the planet. Aether diamonds aren’t just less harmful, less destructive or “more ethical,” they are the first diamonds in the world that benefit the environment instead of damaging it. 

Transforming Carbon Pollution into
Climate Positive Diamonds
Step 1: CO2 is Captured

Direct air capture technology is used to extract carbon dioxide from the atmosphere, setting the patented diamond production process into beautiful motion. This step has no geographic constraints and can be done anywhere in the world. All IGI grading reports for Aether diamonds include the time and location where the carbon was captured, as well as the total amount of CO2 that was removed from the atmosphere in connection with that diamond.

Step 2: Hydrocarbon Synthesis 

The captured CO2 is then synthesized into Atmospheric Methane, the hydrocarbon seed required for growing diamonds in a chemical vapor deposition reactor. Aether is the only diamond in the world where the hydrocarbon seeds are comprised of 100% atmospheric carbon, whereas all other lab grown diamonds require earth mined carbon for the seeding stage.

step 3: Diamond Growth

The Atmospheric Methane seed is then fed into specialized chemical vapor deposition reactors that are poweredby 100% clean energy. Over the next several weeks, diamond crystals grow one ambitious atom at a time.

step 4: Finishing

Once the diamond crystals are fully formed, they are rough cut with a laser then sent out for final polishing.

Less Carbon, More Diamond

Nothing is more luxurious, or more symbolic of ultimate love than diamonds. We think it’s unfathomable for something so revered and precious to cause suffering and destruction. That is why we have partnered with Aether, climate-positive diamonds sourced from the air, transforming atmospheric carbon into the most precious of gems. At every step these crafted diamonds are truly worthy of reverence as symbols of everlasting togetherness. Because nothing defines modern luxury more than making our future together more radiant and leaving the planet more brilliant than we found it.

The Future is a Luxury

100% zero-emission power 

Aether diamonds require only half the energy use of mined diamonds, and is all sourced from sustainable energy providers instead of fossil fuels.


It's estimated that at least 60% of mined diamonds sold in the U.S. have problematic ties to military governments and corruption. Aether is 100% conflict-free and always makes decisions with the wellbeing of life on earth in mind.

cleaner air

While Aether diamonds remove carbon dioxide from the air and clean up the atmosphere, mined diamonds create 143 lbs of emissions per carat.

Fairmined Gold

Going beyond what recycling gold can ever do, Fairmined gold is an active force for good. Mined with minimal environmental impact, and under organizations that are held accountable.


Aether Diamonds saves 127 gallons of fresh water, this is the amount typically used per mined carat. Additionally, Aether Diamonds spare billions of gallons annually from acidic run-off from mines.


Keeping it all above-ground, in stark contrast to the up to 250 tons of earth — and in effect, entire ecosystems — that are removed per mined diamond.
