December’s Dual Birthstones: Tanzanite and Blue Topaz – A Gemological Overview

December is unique among the months, boasting not one, but three recognized birthstones: Tanzanite, Turquoise, and Zircon. However, within the current jewelry market and contemporary gifting traditions, Tanzanite and Blue Topaz have emerged as the most prominently featured gemstones for those born in the twelfth month. This article will delve into the characteristics, history, and significance of these two December birthstones, focusing on their use in necklaces and earring sets, as evidenced by available information.

A Tale of Two Blues: Tanzanite and Blue Topaz

Both Tanzanite and Blue Topaz offer captivating shades of blue, though their origins, compositions, and even perceived energies differ significantly. Blue Topaz is appreciated for its affordability and tranquil aesthetic, while Tanzanite is a relatively recent discovery, prized for its trichroism – the ability to display different colors depending on the viewing angle. Both gemstones are frequently incorporated into elegant jewelry designs, including necklaces and earrings, making them popular choices for December birthdays.

Tanzanite: A Modern Marvel

Tanzanite is a relatively new addition to the world of gemstones, first discovered in the Merelani Hills of Tanzania in 1967. Its unique violet-blue hues quickly gained popularity, and it was subsequently named by Tiffany & Co. after the country of its origin. The gemstone’s appeal lies in its pleochroism, exhibiting shades of blue, violet, and purple depending on the light and viewing angle. Tanzanite is often found in association with diamonds, enhancing its brilliance and overall aesthetic.

Jewelry featuring Tanzanite ranges from simple solitaire pendants and studs to more elaborate designs incorporating diamond halos or intricate settings. Rings, earrings, and necklaces crafted with Tanzanite are available in various styles, catering to diverse tastes. The stone’s versatility allows it to complement different metals, including gold, silver, and platinum. Chordia Jewels offers a range of Tanzanite jewelry, including rings, earrings, and pendants, often paired with diamonds to enhance their brilliance.

Blue Topaz: A Classic Choice

Blue Topaz, a silicate mineral, has been cherished for its vitreous blue hues. The allure of blue topaz stems from its affordability and the sense of tranquility it evokes. It is available in three distinct shades: London blue, Swiss blue, and Pale Sky blue, based on varying saturation levels.

Blue Topaz is frequently featured in both contemporary and classic jewelry designs. Solitaire pendants, three-stone arrangements, and halo pendants are common styles. The gemstone’s affordability makes it accessible to a wider audience, while its beauty ensures its continued popularity. Like Tanzanite, Blue Topaz pairs well with diamonds, creating stunning combinations in earrings, necklaces, and rings. Chordia Jewels showcases a delightful assortment of blue topaz earrings, ranging from simple studs to more elaborate designs with diamond accents.

Historical Context and Symbolism

The historical context of Blue Topaz extends back centuries, with the gemstone being valued for its beauty and perceived metaphysical properties. However, the sources do not provide specific historical details regarding its use in ancient cultures. Tanzanite, being a relatively recent discovery, lacks the extensive historical lore associated with older gemstones.

The sources highlight the symbolism of both stones as representing tranquility and peace. Blue Topaz, in particular, is described as evoking a sense of calm. While specific metaphysical beliefs are not detailed, the association with the color blue often links these gemstones to qualities such as serenity, wisdom, and inspiration.

Jewelry Styles and Market Offerings

The available sources showcase a diverse range of jewelry styles featuring both Tanzanite and Blue Topaz. Chordia Jewels offers a wide selection of rings, earrings, pendants, and necklaces incorporating these gemstones. Designs range from classic solitaires to more elaborate halo settings and three-stone arrangements.

Honey Willow specializes in delicate sterling silver pendants featuring a star-set Blue Topaz, designed and handmade in Bath, England. Carisma Collections offers a stainless steel pendant and earring set with 18k gold plating, providing a more affordable option. These examples demonstrate the versatility of both gemstones and their adaptability to different design aesthetics and price points.

Care and Cleaning

While specific care instructions are not provided in the sources, general guidelines can be inferred based on the gemstones’ properties. Blue Topaz, with a Mohs hardness of 8, is relatively durable and can withstand regular wear. Tanzanite, with a lower hardness of 6.5-7, is more susceptible to scratches and requires more careful handling.

Both gemstones can be cleaned with warm, soapy water and a soft brush. Avoid harsh chemicals and ultrasonic cleaners, as these may damage the stones. It is recommended to store jewelry containing Tanzanite and Blue Topaz separately to prevent scratching.

Purchasing Considerations

When purchasing Tanzanite or Blue Topaz jewelry, several factors should be considered. For Tanzanite, the intensity of the color and the clarity of the stone are important. The presence of strong pleochroism is also a desirable characteristic. For Blue Topaz, the shade of blue and the cut quality are key considerations.

Purchasing from reputable jewelers who provide certificates of authenticity is recommended. This ensures that the gemstones are genuine and of high quality. Chordia Jewels specifically mentions providing a certificate of authenticity with every product.

Personalization and Gift Giving

Honey Willow offers the option to personalize the note inside the gift box, adding a personal touch to the purchase. This makes Tanzanite and Blue Topaz jewelry ideal gifts for December birthdays. The availability of various styles and price points ensures that there is a suitable option for every budget and taste.

Conclusion

Tanzanite and Blue Topaz represent the captivating beauty and diverse appeal of December’s birthstones. While Tanzanite offers a modern and unique allure with its trichroism and violet-blue hues, Blue Topaz provides a classic and affordable option with its tranquil shades of blue. Both gemstones are frequently featured in elegant necklaces and earring sets, making them cherished gifts for those born in the twelfth month. The combination of beauty, symbolism, and versatility ensures that Tanzanite and Blue Topaz will continue to be popular choices for generations to come.
