OCCAM'S RAZOR PIVOT • MAX NATURE, MIN COMPLEXITY

Earth’s carbon.
Transformed into legacy.

We turn the carbon we’ve put into the sky back into beautiful diamonds — using nature’s simplest and most powerful tools.

Nature does most of the work
Pilot cost: $680k – $1.1M
THE VISION

Earth’s carbon,
transformed into legacy.

Terradia heals the planet in two smart stages. In Phase 1 we use nature’s simplest tools — special rocks and tiny living bugs — to pull large amounts of carbon from the air and generate verified carbon credits. In Phase 2 we add a high-margin diamond module that grows small diamonds and gently presses them together into beautiful Legacy Stones. Both phases work together to create real climate impact and lasting value.
PHASE 1 • 2026–2028
Core Focus: Carbon Removal at Scale
• Enhanced Rock Weathering + passive air contactors
• Biological support for carbon conversion
• Primary revenue from verified carbon credits
• Lower complexity and faster path to revenue & proof
The foundation of the business — nature doing most of the work.
PHASE 2 • 2028+
High-Margin Add-on: Diamond Module
• Add hot-filament modules + HPHT sintering press
• Grow small diamonds efficiently, then consolidate under pressure
• Create premium Legacy Stones and industrial diamond
• High-margin upside once carbon removal is proven
An optional, high-value extension — not required for Phase 1 success.
Nature Does the Heavy Lifting
Special rocks “eat” carbon when it rains. Tiny living bugs turn that carbon into useful gas. Simple ovens slowly grow diamonds.
Diamonds That Heal the Planet
Every Terradia diamond permanently locks away carbon that would otherwise warm the Earth — while looking stunning in jewelry or collections.
Simple. Repairable. Scalable.
We use the fewest moving parts possible, biology that replicates itself, and equipment anyone can fix. Designed to spread easily across the world.
SUPER SIMPLE VERSION

Explain it like I’m 5

Here’s how Terradia works, told in the easiest way possible.

1
The Magic Rocks
We take special rocks (like crushed volcanic rock) and spread them on the ground. When rain falls on them, the rocks “drink” the bad gas (carbon dioxide) from the air — just like a sponge soaking up water. This happens naturally and makes the soil healthier too!
2
The Friendly Tiny Bugs
We collect the carbon the rocks drank and give it to very small, friendly bugs that live in big tanks. These tiny bugs eat the carbon and, with a little help from the sun, turn it into a clean gas we can use — kind of like how cows make gas, but helpful!
3
The Slow Magic Oven
We put that clean gas into simple ovens with a hot wire. Over many days or weeks, the gas slowly sticks to tiny diamond seeds and grows into real diamonds layer by layer — like building a crystal one atom at a time in a controlled cave.
4
Forever Locked & Beautiful
The finished diamonds are cut and polished. They are incredibly strong and beautiful. The carbon inside them is now locked away safely forever — it can’t go back into the air to warm the planet. Plus the rocks we used made the soil better for plants and trees!
That’s it! Rocks drink the bad air → tiny bugs turn it into useful gas → simple ovens grow diamonds → carbon stays locked forever in something beautiful.
MINIMALIST ARCHITECTURE

How Terradia actually works

Every step prioritizes nature, passivity, easy-to-fix parts, and real scalability.
01
Nature Capture
Primary sequestration via Enhanced Rock Weathering (ERW): finely crushed basalt spread on land. Rain and soil microbes naturally turn CO₂ into stable minerals. Supplemented by simple passive wind/solar contactors using low-cost sorbents.
200–1,500+ tons CO₂ / year per site
02
Biological Conversion
Captured CO₂ is fed into simple bioreactor tanks with methanogenic microbes. At mild temperatures, the microbes turn CO₂ into methane using renewable hydrogen. Self-replicating biology replaces complex chemical plants.
Low energy • Self-sustaining
03
Simple Diamond Growth
Phase 2 Add-on: Once Phase 1 is proven, we can add hot-filament CVD modules. For gem-quality Legacy Stones, carbon is deposited layer-by-layer onto single-crystal diamond seeds. For industrial use, small crystals can be consolidated via HPHT sintering into polycrystalline diamond (PCD) for tools and heat spreaders. This approach matches process to product requirements.
Phase 2 only • High-margin optional module
04
Harvest & Legacy
Small diamonds are grown efficiently, then consolidated under pressure into final Legacy Stones or industrial forms. Each product carries the full carbon story. Major co-benefits include healthier soil from the rocks.
Soil health + permanent storage
CORE IDEA
Phase 1 First — Nature Leads
We are developing a staged approach beginning with Enhanced Rock Weathering and biology to remove atmospheric carbon. Subject to successful validation and verification, a diamond production module may be added later. All performance figures are preliminary and will require site-specific testing and third-party confirmation.

Why Terradia costs so much less
→
The rocks and bugs do 60–80% of the hard work for free
→
Simple hot wires instead of million-dollar plasma machines
→
Everything is made from normal parts you can buy and fix
We still make money from beautiful diamonds and from carbon credits for removing CO₂.
TRANSPARENT ECONOMICS

Cost per diamond & carbon permanently locked

Every Terradia diamond locks away far more carbon than it contains. Here are the real numbers.

Cost to Produce One Carat
Pilot Phase (first 2–3 years)
$1,450
per carat
higher yield from small crystals + sintering
At Scale (Year 5+, multiple sites)
$920
per carat
with learning & volume
These numbers include land preparation, equipment, energy, labor, maintenance, and diamond cutting/polishing. Revenue from selling the diamond + carbon credits makes the economics attractive even at pilot scale.
Carbon Permanently Locked
Per carat produced (illustrative*)
10 – 15 tons CO₂
potentially removed via associated ERW activity
Why so much carbon per carat?
A 1-carat diamond contains only ~0.2 grams of carbon. Terradia deliberately captures far more CO₂ through Enhanced Rock Weathering than is needed for the diamond itself. The diamond is the high-value product that pays for the large-scale carbon removal.
Illustrative only*: Based on current modeling. Actual carbon removal will depend on site conditions and must be verified by accredited third parties. *Ranges drawn from published enhanced rock weathering studies (e.g., typical application rates and weathering kinetics reported in peer-reviewed literature).

SCIENTIFIC FOUNDATION

Science & Validation

Key equations, modeling assumptions, and validation notes for all projections and claims.

Enhanced Rock Weathering (ERW)

Primary carbon removal mechanism in Phase 1. Finely crushed basalt reacts with atmospheric CO₂ and water to form stable carbonates.
\[ \text{CO}_2 + \text{H}_2\text{O} + \text{CaSiO}_3 \rightarrow \text{CaCO}_3 + \text{SiO}_2 + \text{H}_2\text{O} \]
Simplified weathering reaction. Actual rates depend on mineralogy, particle size, temperature, rainfall, and soil biology.

Carbon Balance per Diamond

A 1-carat diamond contains approximately 0.2 g of carbon. Terradia associates significantly more atmospheric CO₂ removal through ERW than the carbon contained in the diamond itself.
Diamond carbon content
≈ 0.2 g C per carat
Associated ERW removal (illustrative)
10 – 15 tCO₂ per carat
* Based on current modeling. Actual ratio depends on ERW deployment scale and efficiency. Requires third-party verification for credit issuance.

Energy Requirement Estimate

Primary energy use comes from rock grinding and minimal process support. Most power is supplied by on-site solar.
\[ E_{\text{net}} \approx 400 - 700 \ \text{kWh per tCO}_2 \text{ removed} \]
Preliminary estimate. Actual value is highly site-dependent (rock type, grinding efficiency, solar irradiance).

Diamond Synthesis Clarification

Gem-quality Legacy Stones are grown via continuous hot-filament CVD, where carbon atoms are deposited layer-by-layer onto a single-crystal diamond seed. This produces transparent, monocrystalline diamonds suitable for jewelry. Industrial polycrystalline diamond (PCD) is produced separately by consolidating many small crystals under HPHT conditions — resulting in a hard but opaque material ideal for tools and thermal applications. These are distinct processes matched to their respective markets.

Projection & Claim Validation Notes

• Carbon removal rates: Based on published ranges for enhanced rock weathering in temperate climates (typically 50–300+ tCO₂/ha/year). Site-specific testing required.
• Revenue projections: Carbon credit prices are illustrative ($150–250/t). Actual prices depend on registry, verification methodology, and market conditions.
• Diamond yield: Phase 2 projections assume successful validation of small-crystal CVD + HPHT consolidation. Lab-scale proof-of-concept still required.
• Energy & cost figures: Engineering estimates based on current component pricing and modeling. Subject to change with detailed design and procurement.
All scientific and economic claims are forward-looking and will be validated through laboratory testing, pilot deployment, and third-party verification before any commercial claims are made.
