Black spinel is a captivating gemstone increasingly recognized for its unique aesthetic and potent energetic properties. While historically often confused with other gemstones, particularly ruby, black spinel has emerged as a distinct and valued member of the spinel family, and is now celebrated as an alternate birthstone for those born in August. This article delves into the history, geological origins, gemological characteristics, symbolism, and care of this intriguing stone, drawing upon current understanding within the field of gemology.
History and Lore
For centuries, the true identity of spinel was obscured by its frequent misidentification as other, more well-known gems. As noted in historical accounts, some of the most famous “rubies” in royal collections were, in fact, spinels. A prime example is the approximately 170-carat Black Prince’s “ruby,” a historically significant stone that adorned the British Imperial State Crown for generations before being correctly identified as a spinel in the 18th century. This historical confusion highlights the visual similarities between red spinel and ruby, and underscores the importance of accurate gemological analysis.
More recently, in 2016, spinel – including its black variety – was officially recognized as a modern August birthstone, joining peridot and sardonyx in representing those born in this summer month. Historically, red spinel, along with other red gemstones, was believed to possess healing properties, specifically as a remedy for blood loss and inflammatory diseases. It was also thought to promote harmony and ease anger. The tradition of gifting spinel for the 22nd wedding anniversary further demonstrates its enduring cultural significance.
Geological Formation and Sources
Black spinel’s formation is linked to metamorphic activity, a process involving the combination of molten rock with limestone or dolomites. This geological process results in mineral deposits, ultimately yielding the black gemstone. The distinctive black coloration arises from the presence of magnesium aluminium oxide, alongside other minerals like zinc and iron-aluminum oxide.
Currently, the primary sources of black spinel are Myanmar, Sri Lanka, Thailand, Russia, and India. The United States also possesses a few mining operations, though these are relatively sparse. Interestingly, mining activity for black spinel peaked in the 2000s, and current efforts to unearth the gem are limited, contributing to its relative rarity in the market.
Gemological Properties
Black spinel exhibits a hardness of 8 out of 10 on Mohs scale, indicating excellent durability and resistance to scratching. This makes it suitable for everyday wear in jewelry, comparable to sapphire and ruby. The gemstone’s composition primarily consists of magnesium oxide and magnesium-aluminum oxide.
Black spinels are available in a wide range of sizes, with some crystals reaching up to 18 carats in weight. Cutters fashion these rough stones into various shapes, including round, oval, pear, cushion, and a variety of fancy cuts like octagon, baguette, trillion, and marquise.
Under ultraviolet light, black spinel displays a natural red fluorescence, observable under both long and short wavelength UV light. Symmetry and proportion are also important factors in evaluating the quality of a cut black spinel. Certifications from reputable gemological laboratories, such as GIA, IGL, and HRD, provide detailed documentation of a spinel’s characteristics.
The following table summarizes key gemological properties:
| Property | Description |
|---|---|
| Hardness (Mohs) | 8 |
| Composition | Magnesium oxide, Magnesium-aluminum oxide |
| Color | Typically dark black |
| Fluorescence | Red under UV light |
| Common Cuts | Round, Oval, Pear, Cushion, Fancy Cuts |

Care and Cleaning
Due to its hardness of 8 on the Mohs scale, black spinel is a relatively durable gemstone. However, like all jewelry, it requires proper care to maintain its brilliance.
