Unter ultraviolettem Licht zeigt sie eine gelbe Fluoreszenz und ist somit ein eindrucksvolles Beispiel f\u00fcr die Lumineszenzeigenschaften von Spezialglas.<\/p>\n<p class=\"isSelectedEnd\">Durch den hohen Wismutgehalt weist die Perle einen ungew\u00f6hnlich hohen Brechungsindex auf, was ihr im Vergleich zu gew\u00f6hnlichem Glas eine au\u00dfergew\u00f6hnliche Brillanz und ein
