Abstract: The present invention is directed to a method for treating discolored natural diamond, especially Type IIa diamond and Type IaA/B diamond with nitrogen as predominantly B centers, for improving its color. The method includes preblocking and preshaping a discolored natural diamond to prevent its breakage in a high pressure/high temperature (HP/HT) press, placing said discolored 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.

Abstract: An anvil for use in ultra high pressure presses capable of operating in the pressure ranges where diamonds, polycrystalline diamond composites and cubic boron nitride are stable, fabricated by diffusion bonding together a plurality of cemented tungsten carbide layers. The anvil has a working layer adjacent to the highest pressure of the press with the remaining plurality of layers behind the working layer for support. The working layer has a higher hardness than the supporting layers and the supporting layers each have higher toughness than the working layer.
Abstract translation: 用于能够在金刚石，多晶金刚石复合材料和立方氮化硼稳定的压力范围内工作的超高压压机的砧座通过将多个胶结碳化钨层扩散结合在一起而制造。 砧座具有与压力机的最高压力相邻的工作层，在工作层后面的剩余的多个层用于支撑。 工作层具有比支撑层更高的硬度，并且支撑层各自具有比工作层更高的韧性。

Abstract: THE APPARATUS COMPRISES A PLURALITY OF WEDGES HAVING SURFACE DELIMITING, AT LEAST IN PART, A CLOSED SPACE IN WHICH SOME MATERIAL IS PLACED TO BE COMPRESSED. THE WEDGES ARE CONTIGUOUS WITH EACH OTHER ALONG CONTACT FACES, AND ARE ABLE TO MOVE RELATIVE TO EACH OTHER BY SLIDING OF THESE CONTACT FACES ON EACH OTHER, TO REDUCE THE VOLUME OF THE CLOSED SPACE. THE WEDGES MUTUALLY SUPPORT EACH OTHER ALONG THESE CONTACE FACES. THE CONTACT FACES OF EACH WEDGE DIVERGE TOWARDS THE EXTERIOR OF THE APPARATUS BY A DISTANCE SUFFICIENTLY LARGE SO THAT THE EXTERIOR
PORTIONS OF THESE WEDGES WHICH ARE NOT MUTUALLY SUPPORTED HAVE DIMENSIONS SUFFICIENT TO WITHSTAND THE STRESSES APPLIED DURING OPERATION.-
