- •
The formation of monocrystalline (MC) diamonds is still debated.
- •
We conducted the first systematic search for fluid inclusions in MC diamonds.
- •
We examined 30 gemmy twinned diamonds with evolved nitrogen aggregation (high B/(A+B) ratio).
- •
We found 20 microinclusions with compositions that resemble the fluids in fibrous diamonds.
- •
This indicates that most MC diamonds grew from carbonate-bearing fluids.
