I stumbled on this article when searching for some other information.
It even mentions The Gemology Project :wink:

For many centuries gemstones have been noted in history as being the object of status, respect and desire in most cultures. Although from time to time there are new natural gemstone occurrences, the major commercial gems such as diamond, emerald, ruby and sapphire remain in high demand due to their formidable attributes of beauty, durability and rarity. With natural resources depleting and consumer demand ever growing, many gemologists and researchers have resorted to synthetically producing these highly prized gemstones. Over the years synthesis methods have been finely tuned; producing stones which are looking more and more like their natural counterparts. This has become a concern in the gemological world as identification of these synthetics is becoming increasingly difficult through traditional, conventional testing methods. This study is an attempt to uncover the distinguishing features of gemstones of natural and synthetic flame fusion, flux and hydrothermal origin. Furthermore, the desired technique to be used for analysis will be Raman spectroscopy; both being applied in bench top and handheld form.
