Blue Zircon: The Jewellery World's Best-Kept Secret
Blue Zircon - A December Birthstone

The lucky month of December, already full of gifts, also offers the December birthdays a range of gemstones to choose from, all in the beautiful azure shades of blue.
Traditionally Turquoise was the main birthstones for December birthdays, a stone with a long tradition in jewellery from ancient civilisations across Egypt, to Persia and to the Aztecs. More recently further stones in bright blues have been added to the December birthday list - and John Franich stocks them all, from Tanzanite to Turquoise, Topaz and Blue Zircon - view the December Birthstone Collection.
At John Franich Jewellers, our extensive Gemstone Collection includes a wide variety of coloured gems, proudly featuring Amethyst, Aquamarine, Citrine, Emerald, Garnet, Morganite, Opal, Pearls, Peridot, Ruby, Sapphire, and all four of the December birthstones: Tanzanite, Topaz, Turquoise, and Zircon.
Whether you are drawn to the fiery ocean-blue depths of a Blue Zircon or the velvety violet of a Tanzanite, our expert team is ready to guide you through our offerings.Â
The Four Blues of December:
Zircon, Tanzanite, Turquoise & Blue Topaz
If you are looking to mark a December milestone, here is a look at the four beautiful blue options available to you:
- Blue Zircon: As the traditional December birthstone, Blue Zircon is one of nature's most brilliant gemstones, offering a vivid ocean-blue colour and exceptional fire and sparkle that easily rivals diamonds. It requires thoughtful setting and care due to its Mohs hardness of 6 to 7.5.
- Tanzanite: Known for its mesmerising and rich violet-blue hues, Tanzanite is a deeply elegant addition to the December birthstone list. View our Tanzanite Collection.
- Turquoise: An ancient and opaque gemstone cherished for thousands of years, the Turquoise Collection offers a distinct, earthy robin's-egg blue that contrasts beautifully with both silver and yellow gold settings.
- Blue Topaz: A versatile and highly popular gemstone that provides a cool, tranquil, and refreshing aesthetic. The Blue Topaz Collection

Caring for a Precious Stone Like Blue Zircon
Because Blue Zircon has a Mohs hardness rating of 6 to 7.5, it requires thoughtful setting and careful maintenance to protect its exceptional fire and sparkle.
To best care for your Blue Zircon jewellery, you should consider the following:
- Consult an expert: It is highly recommended that you ask an expert jeweller about the specific care requirements tailored to your individual piece.
- Get regular professional maintenance: You can bring your jewellery into the John Franich Jewellers on-site workshop for a "Jewellery Warrant of Fitness". This professional service includes a thorough claw check to ensure your Blue Zircon is securely set, as well as an in-store clean and expert polishing to restore the gemstone's original brilliance.

Choosing Your Radiance: Would a Blue Zircon Suit You?
At John Franich Jewellers, we believe that the colour you choose can amplify your personal narrative, making your jewellery truly yours. So, how does the vivid ocean-blue of a Zircon fit your personal style?
Harmonising with Your Skin Tone
Understanding your skin's undertone can guide you to colours that naturally illuminate your complexion. The ocean-blue hues of a Blue Zircon are incredibly flattering for those with cool undertones (pink, red, or blue undertones). Just like a refreshing aquamarine or a deep sapphire, the tranquil, cool-toned depths of a Blue Zircon create a stunning contrast that will make your skin shine.
Reflecting Your Inner Self
Your jewellery is an extension of your personality.
- For Calm & Romantic Personalities: The soothing, vivid ocean-blue colour reflects a tranquil and sensitive nature, adding a touch of serene elegance to your everyday wardrobe.
- For Bold Characters: Because Blue Zircon displays such exceptional fire and sparkle, it acts as a striking, contrasting pop of colour that makes a memorable statement, perfectly resonating with a strong, adventurous presence.
