Spinel is a captivating gemstone gaining recognition as a noteworthy alternative to more traditional birthstones. Recently elected as an alternative birthstone for August, this mineral boasts a rich history, stunning array of colors, and exceptional brilliance, making it a desirable gem for both collectors and jewelry enthusiasts. This article will delve into the geological origins, gemological properties, historical context, and increasing popularity of spinel.
History and Lore
While not as deeply embedded in ancient lore as diamonds, rubies, or sapphires, spinel has often been mistaken for these more famous gems throughout history. This is largely due to its similar appearance and the fact that it was frequently found alongside rubies and sapphires in historical mining locations. Notably, many famous “rubies” in historical crown jewels are, in fact, spinels.
The recent elevation of spinel as an alternative birthstone for August signifies a growing appreciation for this often-overlooked gem. Its history is intertwined with that of its more celebrated counterparts, yet spinel possesses a unique identity and allure that is now being recognized.
Geological Formation and Sources
Spinel is a magnesium aluminum oxide mineral that crystallizes in the cubic system. It forms in metamorphic rocks and alluvial deposits. Primary sources for spinel include Myanmar (Burma), Sri Lanka, and Tanzania.
The Mogok Valley in Myanmar is particularly renowned for producing high-quality red spinels, often referred to as “Mogok Spinels.” Sri Lanka offers a diverse range of spinel colors, encompassing pinks, purples, and blues. Tanzania’s Mahenge region is known for its intense, neon-like colored spinels. These locations contribute to the gem’s variety and desirability.
Gemological Properties
Spinel exhibits exceptional brilliance and clarity, stemming from its high refractive index and strong dispersion. This allows the gem to exhibit a stunning play of light. It ranks 8 on the Mohs scale of hardness, making it durable enough for everyday wear in jewelry, including rings.
The gem is found in a variety of colors, including red, pink, blue, purple, and even black. Vibrant red and vivid blue spinels are particularly prized, often rivaling the finest rubies and sapphires in quality and appearance. The chemical composition of spinel is magnesium aluminum oxide.
Here's a table summarizing key gemological properties:

Symbolism and Metaphysical Beliefs
While the sources do not extensively detail the symbolism of spinel across various cultures, some modern interpretations suggest that citrine, a gemstone mentioned in relation to birthstone gifting, assists in manifesting dreams, bringing success and prosperity. This association, though specific to citrine, highlights the broader practice of attributing metaphysical properties to gemstones.
Other gemstones mentioned in the context of baptism gifts – pearls, crosses, shells, and doves – carry strong religious symbolism. Pearls represent purity and innocence, while crosses and doves symbolize faith and peace. These associations demonstrate the historical practice of imbuing gemstones with spiritual meaning.
Care and Cleaning
Due to its hardness of 8 on the Mohs scale, spinel is relatively durable and suitable for everyday wear. However, like all gemstones, it benefits from proper care. Cleaning can be performed with warm, soapy water and a soft brush. Avoid harsh chemicals and ultrasonic cleaners, as these may damage the gem. Regular cleaning will help maintain its brilliance and luster.
