Standard Heat TreatmentHigh-temperature heat treatment (1600-1800°C) is applied to over 95% of Vivid Blue Sapphires. This permanent process improves color by dissolving rutile inclusions and intensifies the blue. Widely accepted in the market, it must nonetheless be mentioned in gemological certificates.
Untreated / NaturalUntreated Vivid Blue Sapphires are extremely rare (less than 5% of the market) and highly prized by collectors. Their rarity and natural beauty give them significantly higher value. A prestigious laboratory certificate (GIA, GRS, SSEF, Gübelin) is essential to confirm the absence of treatment.
Beryllium DiffusionControversial treatment that introduces beryllium into the stone at high temperature to modify or intensify color. This treatment significantly affects value (70-90% reduction) and must be systematically disclosed. Detectable by specialized laboratory analysis.
