  • Why does polycrystalline natural diamond turn black

    2013-6-14 · ion-implantation and high-temperature (HT) treatments are available to produce a black diamond. In this paper we focus on the high-temperature annealing in inert atmosphere of low-quality polycrystalline natural diamonds, also known as “boart” or “coated diamond”. They consist of a monocrystalline core surrounded by a polycrystalline coat.
