This book is an attempt to put together and critically analyze the available data on diamonds
processed by the methods involving high pressure, high temperature annealing—so-called …

The burgeoning multi-field applications of diamond concurrently bring up a foremost
consideration associated with nitrogen. Ubiquitous nitrogen in both natural and artificial …

While the first part of this study took a detailed look at the properties, defects and
classification of brown diamonds with deformation-related (DR) brown color and compared …

For this study, the properties of a large sample of various types of brown diamonds with a
deformation-related (referred to as “DR” in this work) color were studied to properly …

Nitrogen-doped CVD diamond treated with electron irradiation and subsequent annealing at
temperatures from 860 to 1900° C was studied using fluorescence imaging, optical …

We have undertaken a study of the common green or orange-brown spots at the surface of
rough diamond specimens, which are caused by alpha particles emanating from radioactive …

Diamond is a unique optical material with ultra-hard lattice, which properties can be altered
by optically active doping defects combined with carbon interstitials and vacancies. Direct …

Color induction in nitrogen-contaminated diamonds was carried out via various procedures
that involve irradiation, thermal treatments (annealing), and more. These treatments affect …

The modification of nitrogen-contaminated diamonds into color-enhanced diamonds is
usually achieved by irradiation and thermal treatment (annealing). These treatments affect …

With the increasing availability of treated‐color diamonds on the market, their
characterization is becoming more and more critical to the jewelry testers and customers. In …
