Blue gemstone jewellery never goes out of style. This season, it’s more on-trend than ever, with rich sapphire tones and sparkling crystals bringing depth to autumn outfits. Blue stones evoke calm and serenity – like the sea or a crisp autumn sky – yet they also carry a regal quality thanks to icons such as Princess Diana and the Duchess of Cambridge, who famously wear sapphire rings. From classic sapphires to modern favourites like London blue topaz and tanzanite, there’s a blue gemstone to suit every look and occasion.

Why choose blue gemstone jewellery?

Blue gemstones are particularly striking in autumn and winter. Deep sapphire and London Blue Topaz pair beautifully with seasonal knits and tailored coats, while aquamarine and turquoise provide a refreshing contrast that brightens darker outfits. For eveningwear, combine bold blue stones with yellow gold for a warm, luxurious finish, or with sterling silver for a cool, contemporary edge. So you've settled on the idea of a beautiful new piece of blue gemstone jewellery. Perfect. But wait - how do you choose between beautiful sapphire, topaz, and aquamarine? Not to mention tanzanite, turquoise, tourmaline, blue diamonds and lapis lazuli. In fact, there are at least 30 different gemstones that can have blue tones. Here are some of our favourite blues stones (in no particular order). Along the way we've dropped in some tips for choosing the right blue gemstone for you.

Blue gemstone #1 - Sapphire

Although sapphire can be found in a range of colours, blue is the most popular. Sapphire is second only to diamond in hardness. This makes it a popular choice for engagement rings and jewellery that you wear every day. It is also highly resistant to breaking and chipping. Sapphire was made even more popular by the choice of Princess Diana to wear a sapphire halo engagement ring. The Duchess of Cornwall now wears this ring. Blue sapphire is also a birthstone for September. Sapphire and diamond halo ring

Blue gemstone #2 - Aquamarine

Aquamarine is named after its soft sea-blue colour. It's known for pastel blue shades that evoke calmness. This dreamy, pale blue gemstone is a member of the beryl family. The family includes other gemstones such as emerald and morganite (another of our favourites, but it's not blue!). Aquamarine is also quite a hard gemstone that is not prone to breakage. It's also the birthstone for March. Aquamarine bracelet

Blue stone #3 - Topaz

Most topaz found in nature is either colourless or a very pale blue, so is often heat treated to enhance the blue tone. This is a common procedure and means that the stone is available in shades ranging from the very faintest of blue through to a deep mid blue. Topaz is particularly affordable due to both its durability and affordability. This makes it perfect for jewellery sets. Blue topaz is a birthstone for December. Topaz ring with diamond shank

Blue stone #4 - Tanzanite

This stone is named after Tanzania, the country it was found in. It is actually a relatively rare gemstone and is only found in a small region at the foot of Mt. Kilimanjaro. Tanzanite is often considered to be an underrated gemstone because it is rare and beautiful, but not as popular as some other blue gemstones. This makes it an affordable alternative to sapphire. It is not quite as hard as sapphire, but can last well with good care. Tanzanite can be found in beautiful shades of blue with a purple tinge.

Blue stone #5 - Swarovski Crystal

So it's not a semi-precious gemstone. But Swarovski crystal has an unmistakeable sparkle that always turns heads. If you are looking for affordable blue stone jewellery, why not try the gorgeous blue Bella V Swarovski pendant? Blue Swarovski necklace

Blue stone #6 – Lapis lazuli

One of the most historic gemstones, lapis lazuli has been prized for centuries for its deep ultramarine colour flecked with golden pyrite.

Worn by ancient royalty and even used to create the ultramarine pigment in Renaissance art, lapis carries a timeless sense of sophistication. Today, it’s a versatile choice for statement rings and pendants.

Ania Haie has re-imagined this ancient stone in the most modern earring design with these Lapis Point Pendant Gold Hoop Earrings.

Blue stone #7 – Turquoise

Turquoise offers a lighter, bohemian feel compared to darker blue stones. With its sky-blue to greenish tones, it’s ideal for casual everyday jewellery and layering with silver pieces. As a December birthstone, turquoise is also a meaningful gift for winter birthdays.

Blue stone #8 – London Blue Topaz

London Blue Topaz has become a contemporary favourite thanks to its rich, darker blue tone with teal undertones. It’s often paired with white topaz or zirconia for a striking contrast. This gemstone is perfect if you want something modern and luxurious, but more affordable than sapphire.

Caring for blue gemstone jewellery

To keep your gemstones looking their best, avoid exposing them to harsh chemicals or ultrasonic cleaners. Instead, use mild soapy water and a soft cloth to gently clean your jewellery.

Softer stones like turquoise and lapis should be stored separately to prevent scratches, while harder stones such as sapphire and topaz are more resilient but still benefit from careful storage.
