Blue Spinel: Properties, Benefits & Meanings

Blue Spinel Overview

One of the few naturally occurring gemstones, Blue Spinel is a beautiful and rare variety of Spinel. Mostly colored blue or violet, it is often faceted like a diamond. Unlike other blue gemstones like Sapphire, Blue Spinel is a naturally forming gemstone and is much more valuable than other blue gemstones.

What is Blue Spinel?

Blue Spinel is a beautiful stone used in Jewelry designs the world over. It is not the best stone for jewelry making due to its softness, but it is still used ornamentally because of its eye-catching blue and violet hues.

It is believed that the Blue Spinal is an excellent stone for communication and creation. It symbolizes throat chakra and all the benefits that go along with it. Truth seekers and compassionate people often find this stone to their liking.

Spinel (Sub-type) belongs to a larger group of minerals known as spinels (super-type). The general formula for magnesium aluminate’s cubic crystal system form is MgAl2O4. A spinel stone may be clear but is usually colored red, lavender, blue, green, brown, black, or yellow.

What are some other names for Blue Spinel?

The following names are also used for Blue Spinel:

  • Blue Ceylanite
  • Cobalt Spinel
  • Blue Stongite
  • Blue Talcspinel

What is the origin of the name?

The name comprises two parts: “Blue” and “Spinel.” The “Blue” part of the name refers to the blue color of the stone. The word “Spinel” in 1779 was given by Jean Demeste from Latin “Spinella,” meaning little thorn, alluding to its sharp octahedral crystals.

Geological Occurrence

This stone is most often found in metamorphosed limestone and mudstone. However, in rare mafic rocks, it can form a primary mineral. In these igneous rocks—which are deficient in alkalis relative to aluminum and where alumina may crystallize as corundum or combine with magnesium oxide to form Spinel —aluminum oxide also occurs. This is why Spinel and ruby are often found in the exact location.

Varieties of Cobalt Spinel

There are two varieties of Blue Spinel stone depending on the particular element responsible for the color.

  • Cobalt Blue Spinel: In recent years, unusual vivid pink or blue spinels have been found worldwide. These stones are called Cobalt Spinel or Cobalt Blue Spinel, and their unique color comes from exposure to cobalt during formation. The name refers to cobalt’s presence, which is responsible for the blue color.
  • Gahnospinel: Gahnospinel is a variety of Spinel that contains significant amounts of zinc. The color of the gemstone ranges from light to dark blue. It has a chemical formula of (Mg, Zn)Al2O4.

Where is It found?

Cobalt Spinel stone is found in many countries worldwide, including:

  • Myanmar: Mogok
  • Vietnam: Luc Yen District
  • Tanzania: Mahenge
  • Canada: Baffin Island

Table of Physical Properties

Typical appearance

Blue Spinel crystallizes in the isometric system as octahedrons, often twinned. It has no cleavage, but it does have a crystalline structure that breaks along octahedral planes. It can be translucent to opaque, and it has a vitreous luster.

With its high iron content, the Sri Lankan Spinel is often darker than other varieties. This creates a blue-greyish or violet-blue color rather than the pure blue it is known for.

The darker the blue spinel stone, the more iron it contains. The best way to appreciate its color is in daylight—especially when standing with your back to the sun.

All spinel gems should be clean and free from inclusions, blue or otherwise. The rock will fetch less on the market if it has visible inclusions or markings.

Blue Spinel Value and Price

Most jewelers are unfamiliar with blue Spinel—it is so rare they never encounter it. The price of a Blue Spinel can range from 2500$ to 10,000$/Ct depending on many factors like:

  • Size: The cost of a Blue Spinel stone increases as the size of the gem increases since larger stones are more difficult to find and cut than smaller ones.
  • Quality: A gemstone’s number of inclusions and imperfections indicates its quality. Clarity is also crucial when evaluating the worthiness of Blue Spinel stones. A clear stone will cost more than one with many inclusions.
  • Color: The color of the Blue Spinel affects its price. The more vibrant and intense the shade, the higher value it has. Also, certain shades are rarer than others, affecting overall value. For example, Darker blues with high saturation are rarer and therefore more expensive than lighter ones.
  • Cut: The cut of a gemstone is just as important as its other qualities. Cut can significantly affect the value and appearance of a stone, sometimes making it worth hundreds or thousands more than similar pieces with comparable color, clarity, and carat weight.
  • Location: The value of a Blue Spinel can also be affected by where it is found. For example, Vietnamese Spinel is currently considered the finest in the world.

How to tell if a Blue Spinel is genuine or not?

Synthetic Spinel can be produced by techniques similar to those used in the production of synthetic corundum, including the Verneuil method and flux methods (invented by Frenchman Edward Frémy). As a result, synthetic Blue Spinel can be used as an inexpensive alternative to natural minerals such as aquamarine, beryl, and emerald.

The following points should be noted to tell whether the Blue Spinel is real or not:

  1. Color: Natural Spinel should have an intense color with varying hues. If the color is consistent throughout without any variation, it may indicate that the stone has been dyed or some other treatment has been performed.
  2. Acetone Test: Do an acetone test. Soak in acetone for a few minutes to see if the color comes off. If it does, then it’s likely fake.
  3. Check for inclusions: Inclusions are natural flaws in the rock, even in natural Blue Spinel stones. If you look closely at your gemstone, you should be able to find them—small and irregularly shaped. If there aren’t any irregularities of this kind, it’s a fake.
  4. Check for weight: Check the weight of your Blue Spinel. If it’s too light, then it may be fake.
  5. Scratch Test: A genuine Spinel gemstone is very durable due to its crystal lattice. Kitchen knives shouldn’t leave a mark on hard stones with a rating of 6-7 or higher. Spinel has a Mohs hardness of 8 and does not have cleavage.
