Показана возможность регистрации спектров поглощения в видимом и инфракрасном диапазонах ограненных драгоценных камней, в том числе в изделиях. Исследование проводилось на спектрометре инфракрасного и видимого диапазонов, оснащенном микроскопом, при работе в режиме отражения. Приведены примеры выявления признаков облагораживания, синтетического происхождения бриллиантов основных форм огранки без пробоподготовки или демонтажа из ювелирных изделий.

There is shown the possibility of recording the visible and infrared absorption spectra in the faceted gems, including those in jewels. Investigation was carried out with the infrared/visible range spectrometer, equipped with a microscope working in the reflection mode. It is demonstrated the possibility to detect signs of treatment, synthetic origin of diamonds of the main shapes without any sample preparation or removing from jewels.
