When most women consider blue engagement rings, they are under the belief that each one the stones topping a jewel of the type is sapphires. That’s a fair and justified premise whatsoever, the sapphire is the stone associated with the color blue. But this assumption might be wrong. There’s another unsung hero on the planet of blue engagement rings. A stone that’s well-known by jewelers, but confused for some other, more prized gems by nearly everybody else, for example, occasionally, jewelry experts. That stone is your blue spinel.
Black spinel is a gemstone made of magnesium oxide and magnesium-aluminum oxide. It is one of the rarest and most valuable gemstones. At the same time, it is one of the most mysterious ones. Even his name is a mystery as no one knows how it got it. Some speculate that it originates from the Latin word “Spinella” which stands for “little thorn,” while others speculate it comes from the Greek word “Spinos” that translates sparkle or spark.
