Yellow Topaz from Germany
According to a recent report in the Spring 2022 issue of Gems & Gemology, yellow topaz from Germany has been found to have high levels of the trace element chromium. This discovery has important implications for gemological research, as it may help to distinguish German topaz from other sources.
The researchers who conducted the study found that yellow topaz from Germany typically contains 200 to 500 parts per million (ppm) chromium, while topaz from other sources typically contains less than 100 ppm chromium. The researchers also noted that the chromium in German topaz is likely to be in the form of Cr3+, which is responsible for the gemstone's yellow color.
In addition to its scientific significance, German topaz is also highly valued by collectors and jewelry enthusiasts for its unique color and clarity. The gemstone is typically found in small sizes (less than 5 carats), but is prized for its intense yellow hue and brilliant sparkle.
