What Is A Black Spinel?

Spinel is a variety of corundum, an aluminum oxide mineral used in everything from jewelry to industrial abrasives. Black spinel is a gemstone from the spinel family, which includes ruby, sapphire, and spinel itself.

This spinel has a high refractive index of 1.712 – 1.736, making it highly brilliant and transparent. The color of this stone is pure black with no brown or purple undertones, as found in wide other varieties of spinel.

The Spinel stone is also harder than most other gems, making it more durable for daily wear and use. It is considered a precious stone because it can be found in large enough quantities to be used in jewelry making.

Although this stone’s use dates back to ancient times, its popularity did not become widespread until the 19th century, when demand for jewelry increased due to industrialization and urbanization across Europe and North America.


Black spinel is a stone with a deep and rich history.

It was first discovered in Sri Lanka. Ancient civilizations were drawn to the stone for its beauty and rarity but also because it had so many practical uses. It was used as currency by metalworkers in India, as well as in trade with China and Africa.

Ancient Egyptians used this gem for jewelry and amulets as early as the 4th millennium BCE. It has also been used in Burma since ancient times, where it was thought to bring good luck in battle if placed on an archer’s bowstring. The Romans also used Black spinel extensively in their jewelry designs throughout history, often pairing it with gold or silver to create elegant pieces of artistry.

In the Middle Ages, spinel was used to make rings for kings and queens all over Europe. A ring made from spinel was said to protect its wearer from disease, drowning, and fire.

Spinel was also believed to have healing properties: it was used to treat gout, rheumatism, and arthritis.


Black spinel is the most purist black with no flaws. It has a very dark, almost obsidian-like appearance.

The spinel crystal is deep and rich in color, and the banding that occurs naturally in this stone is visible. It does not contain inclusions or flaws like its close cousin ruby, which can have color zoning or cracks inside the stone.

This spinel can be found in various shades of black, ranging from jet black to charcoal gray to dark brownish-red, though the most prized are those with a genuine black hue without any tints or shadows of other colors.


Spinels are formed when natural pressures compress titanium dioxide into a gem-grade crystal. This process can take millions of years as the mineral is compressed into layers of thin-film silicon dioxide. The result is a tough gemstone that can withstand high temperatures without losing its beauty or luster.

Unfortunately, Black spinel is one of the most difficult-to-find gemstones on the market today because it’s not widely used in jewelry design.

Unlike diamonds or rubies, this gem is not easily found in jewelry stores due to its rarity in nature. The stone has been used as a gemstone since ancient times, but it wasn’t until the 20th century that it became more popular with jewelers and collectors alike. 

These gems are a great addition to any collection because they are rare. The best way to find this gem is to check online auctions or specialty stores selling them.

Black Spinel vs. Black Onyx

Black spinel is often mistaken for Black Onyx. Both stones are durable and hard, making them well-suited for jewelry such as earrings and necklaces. In addition, the two stones are similar in appearance: their color is deep and dark.

Black spinels come from Australia and India. Black onyx comes from Brazil, Madagascar, Mexico, and Kenya.

This stone is an aluminum oxide gemstone with an octahedral crystal system. It has a vitreous luster (meaning it looks glossy) and usually occurs in shades of black but can also be found in browns. In jewelry, Black spinel is often used in smaller pieces for delicate, glittering designs.

In contrast, Black onyx is a variety of quartz. Onyx is more opaque than Black spinel due to its trigonal crystal system with a waxy luster. In jewelry, it is often used in bigger pieces.

Price & Value

Black spinel stone is one of the most valuable gemstones on the market. It’s a hard, durable gemstone that can be cut into many shapes. Spinel comes in many colors: pink, red, blue, and green. The black variety is rarer than other colors, which makes it more valuable.

Its value depends on the size, quality, and cut of the Spinel. These gems are typically faceted stones with a round, oval or square shape. 

Size: The value of Black spinel depends on the size of the stone. Typically, larger stones are more valuable than smaller ones. However, small stones can still be quite valuable if they have an excellent cut or quality. 

Quality: For a Black spinel to be considered high quality, it must have good clarity and transparency and good color saturation (meaning that there is little or no color variation within its surface). 

Black spinel’s value depends on various factors. A one to two-carat stone could cost about $1200, with the price rising with an increase in size.

On the other hand, you’ll pay about $2400 for a 1-carat stone with no additional treatments such as heating or irradiation (HR).

How To Tell If It Is Real?

  • The Scratch Test: Black spinel is rather hard and cannot be scratched by most materials. To check if your stone is genuine, you can use a diamond ring or fingernail to scratch the gemstone. For a real Black spinel, a diamond ring will leave a nick, whereas a fingernail will be unable to damage the stone. 
  • UV Radiation Light: If there is any UV radiation produced by your jewelry when you shine a UV light on them (especially if they are under 10x magnification), then they are most likely cubic zirconia or some other synthetic material and not actual Black spinel.
