Abstract

L'invention propose un procédé qui utilise une intelligence artificielle (lA) pour prédire une couleur d'un diamant de couleur D-Z ou d'un diamant de couleur fantaisie, soit pour un diamant poli existant soit pour un diamant poli à découper à partir d'un diamant brut. Le procédé comprend l'application soit d'un spectrogramme IR et d'un poids d'un diamant poli existant en tant que données d'entrée à un premier modèle d'apprentissage automatique (ML), pour prédire une couleur D-Z ou une couleur fantaisie du diamant poli existant ou l'application d'un spectrogramme IR et du poids d'un diamant brut en tant que données d'entrée à un second modèle ML, pour prédire une couleur D-Z ou une couleur fantaisie d'un diamant poli à découper à partir du diamant brut.
