Carbon Capture
Air is processed using carbon-capture technology. Carbon dioxide is separated, purified and stored so it can be used in the next stage.
Diamond Education
Everything You Need to Know About Aether Diamonds
Aether Diamonds are laboratory-grown diamonds created with carbon captured from the atmosphere. Instead of beginning with a conventional fossil-derived carbon source, the Aether process is designed to recover carbon dioxide from the air, convert that captured carbon into a usable growth material and form diamond crystals through Chemical Vapor Deposition.
The finished stones are real lab-grown diamonds. They have the crystal structure, hardness and optical properties associated with diamond, but their carbon source and production story are different from those of mined diamonds and many conventional lab-grown diamonds.
This guide explains what Aether Diamonds are, how their published process works, how they compare with other diamond options and what to review before choosing one.
Understanding the Basics
What Are Aether Diamonds?
Aether Diamonds are lab-grown diamonds made using a carbon feedstock derived from captured atmospheric carbon dioxide.
Diamond is a crystal made primarily from carbon. In the Aether process, carbon dioxide is collected from the atmosphere, purified and converted into a high-purity hydrocarbon that can be used inside a diamond-growth chamber.
The diamond itself is then grown through Chemical Vapor Deposition, commonly called CVD. Once growth is complete, the rough diamond material is planned, cut, polished and graded in the same general way as other gem-quality lab-grown diamonds.
Aether is therefore not a separate gemstone species. It is a specific type and brand of laboratory-grown diamond distinguished by its published carbon-capture process and traceability story.
Important distinction:
An Aether Diamond is a lab-grown diamond. It is not moissanite, cubic
zirconia, glass or another diamond simulant.
A Common Question
Are Aether Diamonds Real Diamonds?
Yes. Aether Diamonds are real laboratory-grown diamonds with a diamond crystal structure.
Like other lab-grown diamonds, they can have essentially the same chemical composition, hardness, brilliance and optical behaviour as natural diamonds. The key difference is origin and production method, not whether the finished material is diamond.
To the unaided eye, a well-cut Aether Diamond can look the same as a comparable natural or conventional lab-grown diamond. Reliable origin identification normally depends on disclosure, grading documentation and specialised gemological testing.

The Published Process
How Are Aether Diamonds Made?
Aether describes a four-stage process that moves from atmospheric carbon capture to a finished polished diamond.
Chemical Conversion
The captured carbon dioxide is combined with hydrogen and converted into a high-purity hydrocarbon suitable for diamond growth.
CVD Diamond Growth
The carbon-rich gas enters a specialised Chemical Vapor Deposition chamber, where carbon atoms build on a diamond seed layer by layer.
Cutting and Polishing
The resulting rough material is mapped, planned, cut and polished to create finished diamonds for jewellery.

Stage One
What Does Carbon Capture Mean?
Carbon capture is the process of separating carbon dioxide from a gas stream so it can be stored, reused or converted into another material.
In Aether's published process, atmospheric air is passed through a system that captures carbon dioxide. The recovered CO₂ is then purified and prepared for conversion.
The captured carbon cannot be placed directly into a CVD diamond chamber in its original form. It must first be transformed into a carbon-rich gas that can supply carbon atoms during crystal growth.
The finished diamond contains only a small amount of carbon by mass. Broader environmental claims therefore depend on the full production system, energy sources, carbon accounting and any additional verified carbon-removal activity—not only on the carbon physically present in the stone.
Stage Two
How Captured CO₂ Becomes Diamond-Growth Material
After capture and purification, the carbon dioxide is chemically converted into a hydrocarbon gas. Aether's published explanation describes combining captured CO₂ with green hydrogen to create a high-purity methane feedstock.
Methane is widely used in CVD diamond production because it can be broken apart inside the growth chamber. Carbon atoms then become available to attach to a diamond seed and expand the crystal.
What distinguishes the Aether approach is the stated source of the carbon used to create this methane. Rather than beginning with fossil-derived methane, the process begins with captured atmospheric carbon dioxide.
Stage Three
How CVD Diamond Growth Works
Chemical Vapor Deposition grows diamond crystal layer by layer inside a controlled chamber.
- A thin diamond seed is placed inside the growth chamber.
- A carefully controlled mixture of gases is introduced.
- Energy activates the gas and breaks down its molecules.
- Carbon atoms settle onto the seed and form diamond bonds.
- The crystal grows gradually until enough rough material has formed.
- The rough is removed for planning, cutting, polishing and grading.
CVD is also used for many conventional lab-grown diamonds. Aether's main
point of difference is the published origin of its carbon feedstock and
the way the production process is powered and documented.
Understanding the Difference
Aether vs Conventional Lab-Grown and Natural Diamonds
All three options can be diamonds. Their major differences involve origin, carbon source, production, rarity and environmental claims.

The best choice depends on your preferred origin, budget, design,
documentation and personal priorities. Environmental performance should
be compared using current product-specific evidence rather than broad
assumptions about an entire diamond category.
Understanding the Claims
What Is the Environmental Idea Behind Aether?
Aether's published model combines captured atmospheric carbon, laboratory diamond growth, renewable power and carbon accounting.
Captured Carbon Feedstock
The carbon used for diamond growth is described as beginning with carbon dioxide removed from the atmosphere.
Reduced Dependence on Fossil Carbon
The process is presented as an alternative to using methane or graphite sourced directly from fossil resources.
Renewable Power
Current Aether educational materials state that diamond production is powered with renewable electricity.
No Diamond Mining
The stone is grown above ground, so that individual diamond is not extracted from a mine.
Traceability
Aether emphasises tracking the material from carbon capture through diamond growth, finishing and delivery.
Third-Party Documentation
Product grading and environmental statements should be reviewed alongside current reports, certificates and verification details.
Environmental Terminology
What Does “Carbon Negative” Mean?
“Carbon negative” generally means that an activity is associated with removing more greenhouse-gas emissions from the atmosphere than it causes, based on a defined accounting boundary and method.
Aether has publicly described its diamonds as carbon negative. Such a claim involves more than the small amount of carbon physically locked inside the diamond. It can depend on direct air capture, production emissions, renewable energy, logistics, operational emissions, additional carbon-removal measures and third-party assessment.
Because sustainability programs and verification standards can change, shoppers should review the most current documentation provided for the specific product or collection rather than relying only on an older headline or general brand statement.
Responsible buying tip:
Look for the claim boundary, measurement period, verification provider,
energy source and explanation of whether reductions, removals or
offsets are included.
Understanding Diamond Quality
The 4Cs of Aether Diamonds
Aether Diamonds are evaluated using the same four core quality factors used for other lab-grown and natural diamonds.
Cut
Cut describes how a diamond's proportions and facets interact with light. It has a major influence on brightness, fire and sparkle.
Color
For colourless diamonds, colour grades indicate how much visible body colour is present. Grades closer to colourless usually cost more.
Clarity
Clarity considers internal and surface characteristics, including their size, number, position, nature and visibility.
Carat
Carat measures diamond weight. Shape, cut and proportions also affect how large the diamond appears when viewed from above.
Buying tip:
The Aether production story does not replace normal diamond evaluation.
Compare the individual stone's cut, colour, clarity, carat weight,
measurements and grading report.
Diamond Documentation
How Are Aether Diamonds Graded and Documented?
Gem-quality Aether Diamonds may be submitted to an independent gemological laboratory for grading. Historical Aether materials have identified the International Gemological Institute as a grading partner.
A diamond grading report may include:
- Laboratory-grown origin disclosure
- Diamond shape and cutting style
- Measurements and carat weight
- Colour and clarity grades
- Cut grade where applicable
- Polish and symmetry grades
- Fluorescence information
- Report number and possible laser inscription
Gemological grading confirms diamond characteristics and laboratory origin. It does not by itself verify every environmental claim. Review separate sustainability or traceability documentation where those points influence your purchase.
Product Transparency
What Should Aether Traceability Show?
A strong traceability record should explain how the product moves from raw material to finished jewellery and which organisations verify each stage.
- Source and method of atmospheric carbon capture
- How captured CO₂ is converted into diamond-growth feedstock
- Location or operator of the diamond-growth process
- Energy source used during production
- Independent diamond grading information
- Environmental accounting and verification methodology
- Jewellery metal and manufacturing disclosures where applicable
Documentation may differ between collections, production periods and sellers. Product-specific information is more useful than a general brand statement when making a purchase.

Before You Purchase
Things to Consider Before Buying an Aether Diamond
Aether Diamonds have a distinctive story, but buyers should still evaluate the complete product and current supporting documentation.
Confirm the Stone Is Actually an Aether Diamond
“Made from air” and similar language should be supported by product-specific branding, records or documentation rather than used as a generic description for any lab-grown diamond.
Review Current Sustainability Evidence
Check the latest production, energy, carbon-accounting and verification information because programs and claims may change.
Compare the Individual Diamond
Review cut, colour, clarity, carat weight, measurements and visual performance. A special carbon source does not make every stone equal in quality.
Understand Resale Uncertainty
Lab-grown diamond resale prices are not guaranteed. Purchase the jewellery primarily for its design, meaning and personal value.
Check Availability and Replacement Terms
Branded production and matching specifications may affect future availability. Review warranty, returns and replacement policies.
Consider the Complete Jewellery Product
The setting metal, manufacturing, packaging, shipping and long-term care also contribute to the product's overall impact and quality.
Buying Guidance
How to Choose the Right Aether Diamond
Jewellery Care
How to Care for Aether Diamond Jewellery
Aether Diamond jewellery should be cared for in the same thoughtful way as other fine diamond jewellery.
The diamond will not become cloudy because its carbon came from the atmosphere. However, oil, soap, lotion and dust can collect on its surface and temporarily reduce sparkle.
- Clean gently with lukewarm water and mild soap.
- Use a soft brush around the diamond and setting.
- Rinse carefully and dry with a lint-free cloth.
- Avoid harsh chemicals and abrasive cleaning products.
- Remove jewellery before exercise or heavy physical work.
- Store pieces separately to reduce scratching and tangling.
- Have prongs, clasps and settings checked periodically.
