October Birthstone of Choices

October Birthstones: The Master Jeweller’s Guide to Opal and Tourmaline

October is a month of vivid transformation. As the landscapes shift and the days lengthen toward the holiday season, so do the captivating colours of its celebrated birthstones. At John Franich Jewellers, we believe that a birthstone is far more than just a beautiful gem—it is a personal milestone, a wearable memory, and a piece of history waiting to be crafted into a modern heirloom.

Whether you are celebrating an October birthday, commemorating a special wedding anniversary, or simply drawn to the striking, jewel-toned hues of the season, understanding the history and physical qualities of these stones adds a profound layer of meaning to your fine jewellery collection. Here is our Master Jeweller's guide to October’s finest gemstones: the kaleidoscopic Opal and the vibrant Tourmaline.

Opal: The Canvas of a Thousand Colours

For centuries, the Opal has been revered as the traditional birthstone for October. Its name is derived from the Sanskrit word upala (meaning "precious stone") and the ancient Greek word opallios (meaning "to see a change of colour").

History and Origins

Ancient civilisations believed opals fell from the heavens during powerful lightning storms, imbuing the stones with the magic of the skies. In ancient Rome, the opal was the ultimate symbol of love, hope, and purity. It was considered the most precious of all gems because it seemed to encompass the glowing colours of every other precious stone within its depths. Today, the vast majority of the world's finest opals are ethically sourced from the rugged landscapes of Australia, which produces some of the most breathtaking examples of this gemstone.

Stone Qualities and Shades

The Play of Colour: Opals are globally famous for their unique optical phenomenon. As light enters the stone, it interacts with microscopic silica spheres, scattering into brilliant, fiery flashes—from deep ocean blues and vibrant greens to striking reds and oranges.
Unique Characteristics: No two opals are ever identical. Whether it is a translucent white opal with delicate pastel flashes, or a rare black opal radiating neon hues, each stone is a one-off masterpiece of nature. This makes an opal the perfect choice for a truly bespoke, one-of-a-kind piece of jewellery.
Care and Wear: Opals contain a small percentage of water and are softer than diamonds or sapphires, ranking between 5.5 and 6.5 on the Mohs hardness scale. They require mindful wear to prevent scratching and should be kept away from extreme temperature changes. We highly recommend bringing your opal pieces into our West Auckland boutique for a Complimentary Annual Health Check to ensure the settings remain perfectly secure and the stone retains its brilliance.

Tourmaline: The Gem of Infinite Variety

To complement the delicate nature of the opal, Tourmaline was officially added as an October birthstone in 1952. Its name comes from the Sinhalese word toramalli, which translates to "stone with mixed colours"—a fitting title for one of the most versatile and vibrant gemstones on earth.

History and Origins

Because of its incredible range of colours, tourmaline was frequently mistaken for other historical gemstones. For instance, the famous "Caesar's Ruby" in the Russian crown jewels was eventually discovered to be a magnificent red tourmaline. Legend says that tourmaline travelled along a rainbow from the centre of the earth, gathering all its magnificent colours along the way. Throughout history, it has been prized by royalty and mystics alike, celebrated for its supposed ability to inspire artistic expression and protect the wearer.

Stone Qualities and Shades

A Spectrum of Shades: Tourmaline is available in almost every colour imaginable. October is most closely associated with the romantic Pink Tourmaline, which ranges from soft blush to vivid magenta. You can also find deep forest greens, vibrant blues, and the highly sought-after "Watermelon" tourmaline, which features a striking pink centre surrounded by a green edge.

Dynamic Brilliance: Many tourmalines exhibit pleochroism, meaning the gemstone displays different colours or depths of colour depending on the angle from which you view it. This dynamic quality makes tourmaline an exceptional centrepiece for rings and pendants that catch the light with movement.
Everyday Durability: Scoring a robust 7 to 7.5 on the Mohs hardness scale, tourmaline is structurally durable and highly suited for daily wear. It pairs beautifully with brilliant-cut diamonds and can be set securely in white, yellow, or rose gold to complement its specific hue.

Crafting Your October Heirloom

Choosing between the fiery, ethereal flashes of an Opal and the crisp, vibrant clarity of a Tourmaline comes down to your personal story and how you intend to wear the piece. Because opals require a gentle touch, they are magnificent as statement pendants or occasion rings. Tourmaline, with its sturdy composition, is an excellent choice for a vibrant, everyday signature ring.
