Rough gems require cutting, polishing, and shaping, and sometimes a variety of treatments are required to impart a brilliant appearance. Many of these treatments have been discussed in this blog, including high-pressure, high-temperature (HPHT) treatment and chemical vapor deposition (CVD). Recently, a <em>Producing Polymers and Plastics<\/em> post, <a href=\"http:\/\/admin.acceleratingscience.com\/materials\/did-you-know-polymers-make-emeralds-more-beautiful\/\" target=\"_blank\"><em>Polymers Make Emeralds More Beautiful<\/em><\/a>, examined the practice of fracture or cavity filling with polymer materials to enhance gemstone clarity.<\/p>\n<p>As with other gemstone treatments, even the most experienced jewelers have difficulty detecting polymer fracture or cavity filling. Techniques such as <a href=\"http:\/\/www.thermoscientific.com\/en\/products\/fourier-transform-infrared-spectroscopy-ftir.html\">Fourier Transform Infrared spectroscopy (FTIR)<\/a> and <a href=\"http:\/\/www.thermoscientific.com\/en\/products\/raman-spectroscopy.html\">Raman spectroscopy<\/a> easily determine whether stones such as diamonds, emeralds, rubies, and sapphires have been artificially treated to enhance their color and raise their value.<\/p>\n<p>Here is some additional recommended reading to learn more about some of the minerals that are mined and then become real
