December is uniquely represented by not one, but two captivating gemstones: blue topaz and tanzanite. Both offer a spectrum of blue hues, though their origins, characteristics, and symbolism differ. This article explores the history, gemological properties, and significance of these December birthstones, with a particular focus on their use in promise rings and jewelry designed for lasting commitment.
History and Lore
Blue topaz has long been associated with December, representing love and affection. While the history of topaz itself stretches back millennia, with ancient Greeks believing it had the power to control the winds, the specific association with December is more recent. The modern birthstone list solidified in 1912, and blue topaz gained prominence as the December stone.
Tanzanite, in contrast, is a relatively recent discovery. Found in the Merelani Hills near Mount Kilimanjaro in Tanzania, it was identified by Tiffany & Co. in 1967. Its unique violet-blue hues quickly made it a sought-after gemstone, and it was officially added as a December birthstone, offering an alternative to blue topaz. Ruby & Oscar highlights tanzanite’s increasing rarity and beauty, noting its “trichroic properties” – displaying violet and blue tones – making it stand out among other gemstones.
Geological Formation and Sources
Topaz, in general, forms in igneous rocks and is often found in alluvial deposits. The sources for the blue topaz featured in jewelry are not explicitly detailed in the provided materials. However, the focus is on the gemstone itself within the context of rings.
Tanzanite’s origin is specifically linked to the Mount Kilimanjaro region of Tanzania. The provided sources emphasize its unique geological formation in this area, contributing to its rarity and desirability.
Gemological Properties
Blue topaz, as featured in rings from Saslow Shenebrys, is often set in sterling silver with platinum plating for enhanced durability and brilliance. The gemstone is described as having “calming and soothing properties.” The provided materials do not detail the specific chemical composition, hardness, or refractive index of blue topaz. However, it is presented as a durable gemstone suitable for everyday wear.
Tanzanite, showcased by Ruby & Oscar, is a natural gemstone, often heat-treated to enhance its color. A 0.5-carat round-cut tanzanite is specified in a promise ring setting, alongside cubic zirconia accents. The ring setting itself is made of solid 925 sterling silver, weighing 2.5 grams. The dimensions of the tanzanite are 5 x 5 mm. The sources indicate that tanzanite exhibits violet and blue hues due to its trichroism.
A comparison of properties, based on the provided sources, can be summarized as follows:
