December Birthstone - Tanzanite and Blue Zircon

If you are celebrating your Birthday in December, you are SO lucky!

You have TWO gorgeous birthstones to choose from, Tanzanite and Blue Zircon.

Let's have a closer look at each one.


  • Tanzanite is only mined in one place - Tanzania

  • Finest quality Tanzanite is an intense violet-blue colour

  • Tanzanite was introduced to the world by Tiffany & Co. and was heavily promoted as an exotic stone, it has since become one of their most popular coloured gemstones

Tanzanite Birthstone

Tanzanite is also known for the following traits:

  • brings the feeling of being “centred”

  • facilitates truthful thinking and communication

  • can help open your third eye and help with spiritual awakening

Blue Zircon

  • Zircon exists in a variety of colours including greenish-blue, yellow, brown and white (aka colourless)

  • The majority of zircon comes from Madagascar, Cambodia, Sri Lanka, Myanmar, Vietnam and Australia. Zircon found in Australia is considered to be one of the oldest minerals on earth, estimated at 4.4 billions years old

  • Blue Zircon was very popular during Victorian Era and is often seen in estate jewellery

Is Zircon the same thing as Cubic Zirconia?


People often confuse the two due to their similar sounding names.

Zircon is a natural stone found in nature.

Cubic Zirconia is a synthetic / lab created / man-made stone. It has completely different properties and is much less valuable.

Tanzanite and Blue Zircon are fairly abundant and are available in a large variety of shapes and sizes making them perfect for large statement pieces such as cocktail rings as well as smaller jewellery items.

Tanzanite and Blue Zircon are much more affordable than diamonds, sapphires, rubies, emeralds, and alexandrite.

Many of my clients are pleasantly surprised by how affordable these gems really are.

In terms of hardness, Tanzanite scores a 6 - 7 out of 10 on Moh's scale.

Blue Zircon scores a 6.5 - 7 out of 10.

With sapphires and rubies at 9 and diamonds at 10, these can scratch your tanzanite or blue zircon if not stored properly or if they rub against each other.
