Spinel is generally highly sought after by gem connoisseurs, and well-formed spinel crystals are in high demand among collectors.

Spinel comes in a variety of colors, but the most commercially important are red and pink. Mauve- or lilac-colored spinels are also attractive, and some blue spinel colors can be intense.

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.
