Spinel: A Gemstone with Many Colors and Benefits

Spinel is a gemstone that has been used for centuries, but is often mistaken for other stones like ruby or sapphire. It is a mineral that comes in a variety of colors, from red to blue to black, and has many benefits for jewelry lovers. Here are some reasons why you might want to consider spinel for your next custom jewelry project.

What is Spinel?

Spinel is a naturally occurring mineral composed of magnesium aluminum oxide that belongs to the cubic crystal system. It is found in a variety of colors, primarily due to trace elements like iron, chromium, and cobalt. This means that it has a symmetrical shape and can reflect light in different directions, giving it a sparkling appearance. Spinel can be found in many places around the world, such as Myanmar, Sri Lanka, Tanzania, and Vietnam. It is usually formed in metamorphic rocks or in contact with magma. Its vibrant colors and high clarity make it a sought-after gemstone, though it is often overshadowed by more well-known stones like rubies and sapphires.


Spinel is a durable gemstone at 8 on Moh's Scale of Hardness which is the same as Topaz and Emerald.

  • Spinel can withstand everyday wear and tear without losing its luster. It is durable and resistant to scratches being an 8 on the Moh's Scale of Hardness.
  • Spinel is affordable and accessible, depending on color. Compared to other gemstones of similar quality and color, spinel is often less expensive and more available. You can find spinel in a range of sizes and shapes, and you can customize it to fit your budget and preference. Although red and pink spinel can be rare and more expensive.

This gemstone offers a wide range of colors with excellent clarity, making it an eye-catching choice for jewelry.

What to Consider When Purchasing Spinel


  • Color is the most important factor when buying spinel, as it determines the beauty and value of the stone. Spinel can come in almost any color, but the most desirable ones are red, pink, blue, and purple. Red spinel is the rarest and most valuable, as it can rival the color and quality of ruby. Pink spinel is also highly sought after, as it can range from soft pastel to vivid magenta. Blue spinel is another popular choice, as it can mimic the color and clarity of sapphire. Purple spinel is a unique and attractive option, as it can display different shades of violet and lavender. Grey spinel is also a unique option for those seeking a unique stone that sometimes has hints or lavender or purple. The most valuable spinels have a strong, vivid color with little to no secondary tones. For example, red spinel should have a pure, intense red similar to that of rubies, while blue spinel should exhibit a deep, rich blue.
  • Clarity is the second most important factor when buying spinel, as it affects the brilliance and transparency of the stone. Spinel is usually eye-clean, which means that it does not have any visible inclusions or flaws. However, some spinel may have microscopic inclusions, such as needles, crystals, or fractures, that can affect the light performance and durability of the stone. The fewer and smaller the inclusions, the more valuable the spinel. However, some inclusions can add character to the stone, especially in unique colors like gray or lavender. It's important to inspect the stone under different lighting to appreciate its true clarity.
  • Cut is the third most important factor when buying spinel, as it influences the shape and symmetry of the stone. Spinel can be cut into any shape and style, but the most common ones are round, oval, cushion, and pear. The quality of the cut depends on the proportions, angles, and polish of the facets, which determine how well the spinel reflects and refracts light. The better the cut, the more sparkling and lively the spinel.
  • Carat is the fourth most important factor when buying spinel, as it measures the weight and size of the stone. Spinel can vary in carat weight, from less than a carat to several carats. The price of spinel per carat depends on the color, clarity, and cut of the stone, as well as the supply and demand of the market. Generally, the larger and higher quality the spinel, the more expensive it is.
