Practical Gemology refers to the application of the knowledge of characteristics and properties of gemstones in identification or separation of synthetics and imitations. Diamond grading is included in practical gemology.
In November 1919 and January 1920, in what notoriously became known as the âPalmer Raids,â Attorney General Mitchell Palmer began rounding up and deporting so-called radicals. Thousands of people were arrested without warrants and without regard to constitutional protections against unlawful search and seizure.
In all the Palmer Raids, arrests greatly exceeded the number of warrants that had been obtained from the courts, and many of those arrested were guilty of nothing more than having a foreign accent. Palmer declared the raids a success but announced that the work was far from done.
