摘要： Die Erfindung gehört zum Bereich der Diamantenbearbeitung (Diamantenveredelung), die das Anfärben mit verschiedenen Farben betrifft. Die Erfindung kann in der Schmuckwarenindustrie Anwendung finden. Das Verfahren besteht darin, dass im Kristallgitter eines Naturdiamanten vom Typ la, der Verarmungstypen enthält, oder im Kristallgitter eines Naturdiamanten vom Typ la mit hohem Stickstoffgehalt, der mehr als 800 ppm Stickstoffbeimischung vom Verarmungstyp A oder B1 enthält, isolierte Stickstoffatome in der Substitutionsposition gebildet werden, und zwar vom Verarmungstyp C. Der den Verarmungstyp A enthaltende Naturdiamant vom Typ la wird in einem Hochdruckgerät bei einer Temperatur von mehr als 2150° C bei einem stabilisierten Druck von 6,0-7,0 Gpa ausgeglüht, dann wird er durch einen Elektronenstrom von 5x10
15 -5x10
18 cm
-2 bei 2-4 MEV bestrahlt und dem Aushärten im Vakuum bei einer Temperatur von mindestens 1100° C unterzogen. Der Naturdiamant vom Typ la mit hohem Stickstoffgehalt, der mehr als 800 ppm Stickstoffbeimischung vom Verarmungstyp A oder B1 enthält, wird durch einen hochenergetischen Elektronenstrom mit einer Bestrahlungsdosis von mehr als 10
19 cm
-2 bestrahlt und dem Aushärten im Vakuum bei einer Temperatur von mindestens 1100° C unterzogen. Es ergeben sich Diamanten mit einer Phantasierotfarbe, die für Brillanten mit festen NV-Färbungszentren bestimmt sind, die im Wellenlängenbereich von 400-640 nm absorbieren.

摘要： The present invention is directed to a method for treating discoloured natural diamonds, especially Type laB diamond and Type laA/B diamonds with platelets for improving their color. The method includes placing a discoloured natural diamond in a pressure transmitting medium (40) which is consolidated into a pill. Next, the pill is placed into a high pressure/high temperature (HP/HT) press (10) at elevated pressure and elevated temperature within the graphite stable or diamond stable range of the carbon phase diagram for a time sufficient to improve the color of said diamond. Finally, the diamond is recovered from said press (10). Attractive yellowish-green, greenish-yellow and neon yellow-green diamonds can be made by this method.

摘要： The present invention is directed to a method for treating discoloured natural diamond, especially Type IIa diamond and Type IaA/B diamond with nitrogen as predominantly B centres, for improving its color. The method includes preblocking and preshaping a discoloured natural diamond to prevent its breakage in a high pressure/high temperature (HP/HT) press, placing said discoloured natural diamond in a pressure transmitting medium which is consolidated into a pill. Next, the pill is placed into a HP/HT press at elevated pressure and elevated temperature within the graphite-stable or diamond-stable range of the carbon phase diagram for a time sufficient to improve the color of said diamond. Finally, the diamond is recovered from said press. Colorless and fancy colored diamonds can be made by this method.
