Spinel is the magnesium/aluminium member of the larger spinel group of minerals. It has the formula MgAl2O4 in the cubic crystal system. Its name comes from Latin “spina” (arrow). Though spinels are often referred to by uninformed people as rubies, as in the Black Prince Ruby, the true ruby is not a spinel. Balas ruby is an old name for a rose-tinted variety of spinel.
Although spinel has been used in jewelry since ancient times, this gemstone has only recently received the attention it deserves. Before the rise of modern gemology in the late 19th and early 20th centuries, spinel was often identified as corundum, as they are often found in the same mines. Nevertheless, these minerals are chemically distinct. Subsequently, as jewelry enthusiasts were told some of their treasured rubies and sapphires were actually spinels, the stone’s reputation suffered. Furthermore, synthetic spinel is inexpensive and common. It has frequently been used as a simulant for other gems in class rings and birthstone jewelry, which has affected its public perception. Natural spinel, however, has always been a rare and beautiful gem. As more information comes to light about the extensive and invasive enhancements lower-grade ruby and sapphire receive to “pump up” their color or clarity, educated consumers have come to appreciate spinel’s natural beauty. The natural spinels in today’s market are almost all untreated. Their relatively modest prices, availability in nearly any color, hardness, and suitability for most types of jewelry make them even more inviting.
