Spinel Meaning and Properties

Spinel History


It wasn't long ago that spinel was thought to be a ruby due to its lustrous orange-red color. Mineralogist Jean-Baptiste Louis Romé de L’Isle was able to identify differences between rubies and spinel minerals in 1783. Multiple stones previously assumed to be rubies are now able to be identified as spinel. There are two spinel gems, in fact, in the English Crown Jewels. Although spinel appears in a variety of colors such as pink, blue, purple and black, the brilliant reds are most popular and are sometimes referred to as "flame spinel." Spinel deposits occur all over the world, but Southeast Asia was known in ancient times for exceptionally large spinel formations. Spinel has been added as an alternative August birthstone in recent years.

What are the Metaphysical Properties of Spinel?


Diamonds are the gemstone most people associate first with love, but perhaps red spinel should be. Spinel gems are said to help a person set aside ego and become devoted to another person. Like most fiery red stones, spinel meaning is linked to great passion, devotion and longevity. Spinel is associated with the root chakra , making it effective in increasing physical energy and stamina. It seems spinel meaning is also tied to mental stamina, as it is said to reduce forgetfulness and boost intellectual power.


What is Spinel Made From?


Spinel minerals are a magnesium aluminum oxide with varying other impurities that affect color. The presence of chromium results in red, pink and orange spinel. Spinel gemstones have isometric crystal systems. This gem is famous for spinel twinning, where two octahedral crystals twin together at the base. Spinel gemstones range in opacity from transparent to opaque, and the luster can be vitreous, submetallic or dull.

How Do You Clean Spinel?


Spinel is a hardy stone with a Mohs hardness of 8. There are multiple gemstone cleaning techniques that are safe for spinel. Steam cleaners and ultrasonic machines are both safe methods. Typically, however, an untreated soft cloth and soapy water will be enough. It is not recommended to boil spinel as a cleaning method. Since spinel has a high Mohs hardness, store this gemstone away from softer gems so as not to mar the surface of those gemstones.

Since spinel occurs in multiple colors, this gemstone is a versatile addition to jewelry designs. Black spinel provides sophistication alongside pearls or clear gemstones such as quartz crystal. Fiery-red spinel stands out against black gemstones such as jet and silver beads. Red spinel can be used to create Christmas jewelry when paired with green gems such as emerald.
