Sapphire - September Birthstone

Did you know that sapphires exist in every colour of the rainbow?

When the word “sapphire” is used alone it refers to BLUE sapphire.

Any colour other than blue falls into the “fancy” sapphire category and is called by its colour, eg. purple sapphire, green sapphire, blue-green sapphire etc.

Let's take a look at some fun facts about these wonderful gems:

  • The word sapphire come from Latin and Greek words for “blue”

  • Sapphires in all colours are a part of the “corundum” family (red corundum is called a Ruby)

  • The most famous sapphire is considered to be Princess Diana's 12 carat oval sapphire engagement ring. It is now worn by Catherine, Duchess of Cambridge

  • Padparadscha (“Pad-pa-rad-sha”) is considered the most rare variety of fancy sapphire, it shows a unique combination of pink and orange colours and is named after a lotus flower. It is also the centre stone in Princess Eugenie’s engagement ring.

Where do Sapphires come from?

Sri Lanka is a major source of blue sapphires, fancy sapphires as well as rubies. No wonder it is known as the “island of gems”.

Other sources of fancy sapphires around the world include Madagascar, Tanzania, Kenya, Thailand, Vietnam and USA.

Blue-green or teal sapphires have become extremely popular in the last five years. This stunning blue-green or teal sapphire in our Serena Ring was ethically sourced in Madagascar.

It is available for purchase from our Ready-to-Wear collection.

A relatively new sapphire source is Montana, US, which is often associated with ethically sourced sapphires.

It produces a gorgeous variety of green, blue-green and teal sapphires along with other colours.

The term "Montana Sapphire" is often used to describe sapphires in the blue-green colour range.

We have a one-of-a-kind Montana sapphire featured in our Cerelia Ring (below) surrounded by a halo of natural diamonds.

It is available for purchase from our Ready-to-Wear collection.

Heat treatment is an industry standard for sapphires of all colours.

In fact, almost 99% of sapphires are heat treated to enhance and stabilise the colour, it is a permanent process.

Non-treated sapphires are more rare and difficult to find, typically they are also more expensive.

As most sapphires undergo heat treatment, do not be surprised if you do not see a mention of it in your appraisal or grading report. Typically, appraisals and grading reports will only state “no indication of heating” in case of unheated stones.

This unique blue-green sapphire in our Serena Ring has not undergone treatment, which is stated in a third-party appraisal.

In terms of hardness, all sapphires score a 9 out of 10 on Moh's scale.

The only harder material is a diamond at 10.

Due to their hardness, sapphires in any colour are a spectacular choice for an engagement ring that will withstand everyday wear.
