Title (EN) FINGERPRINTING AND ANALYZING GEMSTONES
(FR) PRISE D'EMPREINTE ET ANALYSE DE PIERRES PRÉCIEUSES
Abstract:
(EN) The embodiments disclosed herein relate to the examination of gemstones including diamonds, both cut/polished and rough, using the technology of Resonant Ultrasound Spectroscopy. The resonant frequencies are obtained by mechanically causing the stone to vibrate using a swept sine oscillator, sensing the resonance vibrations, and displaying the spectrum to yield a pattern describing the stone. The resonance fingerprints can be used to both track an individual stone to verify its integrity or to grade a rough stone to establish potential value.
(FR) Les modes de réalisation de la présente invention concernent l'examen de pierres précieuses comprenant des diamants, aussi bien découpés/polis que bruts, à l'aide de la technologie de spectroscopie ultrasonore résonnante. Les fréquences de résonance s'obtiennent par vibration mécanique de la pierre à l'aide d'un oscillateur sinusoïdal balayé, par détection des vibrations de résonance et par affichage du spectre pour produire un motif décrivant la pierre. Les empreintes de résonance peuvent servir à examiner une pierre individuelle, à vérifier son intégrité ou à classer une pierre brute pour établir sa valeur potentielle.
