The Black Spinel is an exquisite gemstone, hiding its stunning beauty behind a self-contained, dignified exterior. It is not an exuberant hue that relies solely on sparkle for attention; rather, its strength and history serve as indicators of its enduring elegance. As compared to Onyx (a similar gemstone) and the many flashier options available to consumers today, the Black Spinel provides a wonderful depth of character beyond its dark appearance, and it should definitely be considered for use in all types of jewelry.

In this guide, you'll learn everything there is to know about black spinel, including its meaning, identifying characteristics, breaking power, origin, historical uses within society, and similarities and differences between other types of stones.

What Is Black Spinel?

Black spinel is a real stone from the spinel family of minerals; it's an oxide of magnesium and aluminum that has a cubic crystal structure. Black spinel gets its black color from trace minerals in it. It has a rich, deep color with some transparency, along with a very fine shine due to its high luster.

Unlike most blacks, black spinel does not undergo a dyeing process. A stone-like black onyx is usually dyed and therefore has an unblemished color throughout. By contrast, black spinel has a natural color.

Like other spinels, black spinel can come in various colors, including red, blue, pink, purple, and orange. However, black spinel has particular characteristics that make it a desirable choice as an elegant addition to your collection of jewelry, with its strength and contrast to the colors of other stones.

The History and Historical Significance of Spinel

Although spinel has been an important gemstone for centuries, most people have never thought too much about it because they have always thought that rubies and sapphires are better gemstones. In fact, before the development of modern gemology, many people confused spinel with rubies and sapphires because of their similarity in color and crystal structure. 

The Black Prince’s Ruby is a famous example of a spinel; it is a huge red spinel that is part of the British Crown Jewels and was thought to be a ruby for hundreds of years. Many examples such as this show that spinel was a very popular gemstone among European, Asian, and Middle Eastern royalty throughout the ages.

There are far fewer historical records regarding black spinel than there are regarding red spinel, but black spinel and other dark gemstones have historically been associated with protection, authority, and grounding. Many cultures believed that dark gems were protective talismans for warriors, travelers, and leaders, and that wearing them could protect them from danger and negative energy.

Black Spinel Uses

Jewelry

Black Spinel vs. Onyx: What’s the Difference?

People often compare black spinel and black onyx because they look alike, but they are very different. Black spinel is tougher, lasts longer, and is black by nature. It shines brighter and more like glass, and it works better in faceted jewelry.

Black onyx is a type of chalcedony that is softer and is often dyed to make its color stand out. It looks smoother and more matte, and it needs less care. Black spinel is usually the better choice if you want something that will last and look great.
