Gemological Properties
Each of December’s birthstones possesses unique gemological properties that contribute to its beauty and suitability for jewelry. A comparative overview is presented below, based on information from the provided sources:
| Gemstone | Color & Varieties | Mohs Hardness | Symbolism / Meaning | Typical Uses in Jewelry |
|---|---|---|---|---|
| Turquoise | Blue to green (often opaque, sometimes with matrix) | 5 – 6 | Protection, healing, friendship | Necklaces, pendants, statement pieces |
| Tanzanite | Violet-blue to deep blue (pleochroic) | 6 – 7 | Transformation, intuition, spiritual growth | Earrings, pendants, occasional rings |
| Blue Topaz | Sky Blue, Swiss Blue, London Blue | 8 | Clarity, communication, calmness | Rings, necklaces, daily wear pieces |
| Zircon | Brilliant blue (but also multi-color) | 6.5 – 7.5 | Wisdom, prosperity, good fortune | Earrings, halo rings, accent stones |
Blue Topaz stands out for its durability, registering an 8 on the Mohs hardness scale, making it well-suited for everyday wear, particularly in rings and necklaces. Tanzanite and Zircon are moderately durable, with hardnesses of 6-7 and 6.5-7.5 respectively, and are often best suited for earrings or settings where the edges are protected. Turquoise is the softest of the four, ranging from 5-6 on the Mohs scale, and is typically used in necklaces, pendants, and statement pieces.
Tanzanite is notable for its pleochroism, meaning it displays different colors when viewed from different angles. Blue Zircon is distinguished from cubic zirconia, being a natural gemstone with excellent brilliance and fire, and a high refractive index that can rival diamonds in sparkle.
Symbolism and Metaphysical Beliefs
The December birthstones are rich in symbolism. Turquoise has long been associated with protection, healing, and friendship. Tanzanite is linked to spiritual growth, transformation, and intuition. Blue Topaz represents clarity, communication, and calmness. Zircon symbolizes wisdom, prosperity, and good fortune.
These symbolic meanings contribute to the appeal of these gemstones, offering wearers a connection to qualities they value or aspire to embody. The stones are believed to carry energies that can positively influence the wearer’s life, though these beliefs are not scientifically verified.
Care and Cleaning
Due to the varying hardness and stability of these stones, their care requirements differ. Turquoise, being the softest, requires gentle handling and should be protected from scratches and harsh chemicals. Tanzanite, while more durable than Turquoise, is still relatively delicate and benefits from protective settings. Blue Topaz, with its higher hardness, is more resilient and suitable for daily wear, but should still be protected from impacts. Zircon, while possessing good brilliance, can be brittle and should be handled with care.
General cleaning recommendations include using warm, soapy water and a soft cloth. Avoid ultrasonic cleaners and harsh chemicals, especially for Turquoise and Tanzanite. Regular cleaning will help maintain the brilliance and beauty of these gemstones.
