R43 identifies exactly 24 public-record unmodified Fancy Red diamonds over 1 ct; private stones are excluded. R46 separately documents a 399-stone FTIR dataset, including 156 known Argyle stones. Neither figure is a lifetime grading census; do not add overlapping populations.

0.5% × 90,000 (R04), Jan 2008–Dec 2016. Inferred point only. The separate 2025 FTIR dataset contains 399 Fancy Reds (R46).
Diamond type does not prove Argyle origin. In R46, 156 of 399 have known Argyle origin and 3 are reportedly Brazilian; other origins are mostly unknown. R43 lists 24 public-record stones >1 ct.

More than one million is a floor, not the exact denominator. No 700-stone count can be recovered.
56.9% of the red category; source also states ~0.04% of all fancy-color submissions. Exact count unavailable. The 399 FTIR spectra are a separate analytical sample.
Table 1 identifies 24 public-record unmodified Fancy Red diamonds over 1 ct. Additional privately owned stones are excluded. This is neither an upper bound on all stones nor a lifetime grading census. Corrected 26 September 2026.
Direct analytical dataset size, not an independently stated total of all GIA grading reports. Includes 156 known Argyle and 3 reportedly Brazilian stones. Do not add to overlapping study or tender cohorts.
156 of the 399 analytical stones had known Argyle origin. This does not establish the mine origin of all other Fancy Red diamonds; remaining origins are mostly unknown.
Three stones were reportedly recovered in Minas Gerais, Brazil. Origin confidence is preserved as reported by the paper. This subset is already included in 399.
Direct count takes precedence over rounded 1% chart.
Grading correspondence requires individual reports; see AR13.
Not an increment to lifetime GIA totals; cohort overlap unknown.
