Testing such small coloured gemstones is challenging, starting with the handling of such small stones to analytical restrictions and limitations due to their small size. To be able to provide the industry a gemmological service for such calibrated coloured stones, the SSEF has adopted a specific testing protocol, combining microscopic observation with spectroscopic analyses including trace element analysis by GemTOF mass spectrometry.<\/p><p>Typically, the first and most important request from our clients is to con rm that no synthetic stone is mixed within the submitted parcel of coloured gemstones. Interestingly, we have found repeatedly single synthetic stones in such series of calibrated coloured stones. A challenging task, as we then sort out such a synthetic stone immediately from the rest of the submitted parcel. This shows that our testing provides crucial information to our clients and allows them to be sure that no synthetic stone is set in their prestigious jewellery or watches. Coming back to the question of Figure 1 above, the outermost stone on the right side proved to be a synthetic purple sapphire after testing at SSEF.<\/p><p>In addition to this, we also provide certain information about treatment conditions, always indicating also the limitations of our conclusions due to the small size of such calibrated coloured stones.<\/p><p>Figure 2 shows a concentration-diagram of the trace elements tantalum (Ta), tin (Sn), niobium (Nb), boron (B), and beryllium (Be) measured by GemTOF in a series of calibrated yellow sapphires. The presence of distinct concentration \u201cpeaks\u201d of beryllium (on the left side of the diagram) combined with practically no traces of the other displayed elements indicates that the yellow sapphires on the left were treated by beryllium diffusion.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0438f58 elementor-widget elementor-widget-image\" data-id=\"0438f58\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"960\" height=\"610\" src=\"https:\/\/www.ssef.ch\/wp-content\/uploads\/2023\/06\/302_Fig2_calibrated-jpg.webp\" class=\"attachment-full size-full wp-image-29505\" alt=\"\" srcset=\"https:\/\/www.ssef.ch\/wp-content\/uploads\/2023\/06\/302_Fig2_calibrated-jpg.webp 960w, https:\/\/www.ssef.ch\/wp-content\/uploads\/2023\/06\/302_Fig2_calibrated-300x191.webp 300w, https:\/\/www.ssef.ch\/wp-content\/uploads\/2023\/06\/302_Fig2_calibrated-768x488.webp 768w\" sizes=\"(max-width: 960px) 100vw, 960px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Figure 2: GemTOF analyses of beryllium and other trace elements of a series of calibrated yellow sapphires.
