A real diamond, grown from them alone.
Chemically and optically identical to a mined diamond — because it is one. The only difference is where the carbon came from: your companion.
Our own CVD laboratory
A heavy-asset lab with full in-house control over every stage.
Chemically and optically identical to a mined diamond — because it is one. IGI-certified, every time.
Hair and fur are nearly half carbon, the building block of every diamond. A small lock is all we need.
Yours is grown alone in its own reactor, from their carbon. Never batched, never repeatable.
Real diamond growth can’t be rushed. We keep you updated at every stage of the journey.
Carbon — the building block of all life.
Every living being is built on carbon. Hair and fur are 45–50% carbon; bone ashes 3–9%. This carbon — the literal substance of a life once lived — is the raw material for your memorial diamond.
Diamonds are the purest form of carbon. By extracting and growing theirs into a crystal, we aren’t creating something artificial. We’re revealing the most perfect form their carbon can take.
Why we grow with CVD, not HPHT.
Inside a vacuum chamber, high-energy microwave plasma frees carbon atoms that settle — one atomic layer at a time — onto a diamond seed. Unlike High Pressure High Temperature, CVD needs no metal catalysts and gives us total control.
HPHT needs iron or cobalt seeds. CVD uses none — nothing foreign near their carbon.
Cleaner, more controlled crystal growth means a purer, brighter stone.
Precise control over every growth parameter — size and form to your specification.
Built atom by atom on a diamond seed, one perfect lattice layer at a time.
The ∞ form has no end and no beginning — a love that simply continues.
Their enduring spirit, bound into the hardest substance on earth.
A gem that shines forever, just like the memories held within it.
Love and memory live on infinitely — a visible promise of that.
The Eternity Cut, modelled on infinity (∞).
Every Caro diamond is finished to our signature Eternity Cut — its form drawn from the infinity symbol, then hand-polished by master craftsmen to maximise brilliance and fire. A timeless shape for an endless bond.
Three stages, eighteen careful steps.
Step 1Carbon Extraction & Purification
- 1.1Labelling & TrackingEach sample gets a unique traceability code for the entire journey.
- 1.2GrindingAshes are milled to expose more surface area for purification.
- 1.3Chemical PurificationCalcium phosphate and minerals are removed, isolating pure carbon.
- 1.4High-Temperature TreatmentTreated in oxygen-free conditions to prevent oxidation.
- 1.5VaporisationThe purified carbon is converted to gas, ready for the chamber.
Step 2CVD Diamond Growth
- 2.1Seed PreparationA high-purity diamond seed is placed in a vacuum chamber.
- 2.2Carbon Gas IntroductionA precisely controlled carbon-rich gas mix enters at low pressure.
- 2.3Plasma ActivationMicrowave plasma breaks the gas down, freeing carbon atoms.
- 2.4Layer-by-Layer GrowthAtoms settle onto the seed into a perfect lattice, one layer at a time.
- 2.5Controlled DurationGrowth runs for weeks to months depending on carat.
- 2.6Post-Growth TreatmentThe raw stone is cooled and extracted — a natural cognac tint is normal.
Step 3Cutting & Polishing
- 3.1MarkingMaster cutters map the optimal cutting areas from internal structure.
- 3.23D ScanningHigh-precision scanning maps the stone's internal composition.
- 3.3DesignThe cut balances weight, optical performance, and your wishes.
- 3.4Laser CutMicron-level laser precision, with no stress fractures.
- 3.5PolishHand-polished to smooth every facet and reveal maximum fire.
- 3.6Quality ControlFinal 4C grading and certification before delivery.
Two colours — and we never fake either.
We reject artificial colour modification entirely. Your diamond is either its natural cognac hue, or a hand-selected transparent stone. Nothing is dyed or treated to deceive.
Natural Cognac
The untouched, warm golden-brown of a CVD diamond — its colour comes straight from their carbon. Nothing added, nothing changed.
Transparent
A rare colourless stone, hand-selected for purity. A clear, classic brilliance. (+premium)
Graded by the 4Cs. Tracked from sample to setting.
Every diamond is graded on Colour, Clarity, Cut, and Carat, and arrives with a full IGI certificate and a unique traceability code linked to the original sample. You always know exactly where they are.
