Yesterday, I spent the whole day learning about gemological materials.
Along the first 7 hours' class of Gemology, Rui Galopim de Carvalho introduced us to the vast universe of minerals, rocks and gemstones.
Among a valuable range of information, we've learned about concerns around evaluating a gemstone and how different shapes and cuts can enhance or destroy its characteristics.
Today, as I was browsing through the links he gave us, I found this interesting test in the Gemological Institute of America (GIA), where you can check your own level of info on gemstones. It's very simple and fun, yet it can really help you to be able to distinguish some important aspects that define the quality of a gemstone and, of course, its price. Give it a try :)
