The word sapphire originates in French, Latin, Greek and Hebrew and has been a historically significant gemstone for thousands of years. In its most pure form sapphire is perfectly colourless but takes on transitional elements during formation to give it various tones of colour – blue being the most common.

Sapphire is commonly synthesied in a number of common techniques and is often used for commercial purposes like watch glasses, coatings to increase durability of products and in electronics. Synthetic sapphire for jewellery is very inexpensive and has been used for a century.

Blue sapphires are prized for their vivid blue colour and the most exquisite examples are a straight blue (with no secondary overtones) hue with no eye visible inclusions, bright and well saturated. Unusual forms of sapphire like cats eyes, star sapphires, colour change sapphires and bi-coloured (parti-sapphires) are also found.

Blue Sapphire Engagement Rings

In terms of popularity, the sapphire is second only to the diamond. Nothing complements the perfect engagement ring quite like a sapphire. While the blue sapphire is the most common colour variant, and many couples go for blue sapphire engagement rings, there are many questions about them that we are here to answer.

A sapphire is a gemstone made from corundum, a crystallised form of aluminium oxide. The blue colour commonly associated with sapphires comes from the concentration of certain minerals within the corundum, such as iron, titanium, vanadium and chromium. Blue sapphires come in various hues, shades and levels of saturation.

Blue sapphire engagement rings are a fairly common trend, serving as an alternative to the more traditional diamond engagement ring.

What are blue sapphires used for?

Blue sapphires are used for all kinds of jewellery, from engagement rings to pendants to bracelets, as many find its strong blue hue to be aesthetically pleasing.

Sapphires have even been used in the application of certain technologies including semiconducting circuits, body prosthetics and titanium lasers. 


Not only are sapphires beautiful to look at, but they have practical applications that make them extremely valuable.

What are the benefits of wearing blue sapphire?

As previously mentioned, not only are blue sapphire engagement rings commonly associated with celebrities and nobility, but their high durability means they are extremely scratch resistant.

How can I tell if my blue sapphire is real?

The easiest way to determine whether or not your blue sapphire is real is to purchase it from a reputable source, such as Holdsworth Bros. Jewellers.

There are many different types of synthetic, treated and imitation sapphire:

  • An imitation sapphire is a material that is simply designed to look like sapphire, it may be glass or even a composite gem with real sapphire on the top but glass on the bottom.
  • A synthetic, often called created, cultured, lab grown or man made sapphire has all the same chemical, optical and physical characteristics as its natural counterpart only is produced in exceptionally high numbers and has almost no commercial value.
  • Sapphire is treated in many unacceptable ways, one of the most prolific currently is to take very light coloured natural sapphire and to dunk it in a bath of coloured molten glass. The colour from the bath leaches in to the very surface of the sapphire making it look a lot more colourful than it actually is. This treatment is called diffusion coating.

What to look for in a sapphire engagement ring

The large variety of shapes and colours with blue sapphires means that there is something for everyone. Personal preferences should always take precedence when selecting an engagement ring for that special someone. It’s better to find a ring that your significant other will cherish because it matches their sensibilities than a ring that commands a bigger price tag. With that in mind, it’s advisable to look for rings that showcase their gemstone adequately while also being comfortable to wear and not requiring constant maintenance. 

How can you tell a good quality sapphire?

The best quality sapphires share the following traits:

  • Colour that is as close to royal blue as possible (i.e. not too bright, not too dark). Also, sapphires that feature colour zoning (i.e. the colour fades into transparency instead of filling the entire gemstone) are of a lesser quality.
  • Minimal visible inclusions. The less inclusions that are visible to the naked eye, the higher the quality of the gemstone. However, no inclusions at all could be a sign that the gem is fake, so be careful.
  • Symmetrical cut sapphires command a higher asking price than asymmetrical gemstones.

Are dark blue sapphires valuable?

Dark blue sapphires are valuable, as they are precious gemstones. However they are sold for cheaper than their brighter, more saturated counterparts. Still, this fact should not deter anybody with a personal preference for darker gemstones. While they might not have the most compelling resale value, dark blue sapphires are nonetheless mesmerising and still make for beautiful engagement rings. 

A notable example of a dark blue sapphire would be the blue-violet Star of Bombay, a cabochon-cut 182 carat gemstone that was given to silent film actress Mary Pickford by her husband Douglas Fairbanks, only to be bequeathed to the Smithsonian Institution in 1979. 

How to care for a sapphire engagement ring

Sapphires are easy to care for, only requiring cleaning every six months or so. You will need warm water and any type of cleaning detergent that has degreasing properties (unless the ring has a silver alloy, as silver can react poorly to detergents). All you have to do is scrub the ring with a soft toothbrush and then rinse it thoroughly. However, avoid using any chemicals that contain moisturisers, abrasives or anti-static agents, as these can leave residue and, at worst, damage the metal band.

Are sapphire rings fragile?

Sapphires rank a 9 out of 10 on Mohs scale of hardness, a scale developed by German geologist and mineralogist Friedrich Mohs in 1812. Not only are sapphires extremely durable against abrasions, they are very chemical resistant as well. 

Can you wear sapphire everyday?

Because sapphires are so durable, they present a very practical solution for engagement rings as they can be worn daily with a very low susceptibility to chips or scratches. While there are circumstances where it is advisable not to wear your ring (i.e. when showering), a blue sapphire engagement ring will survive the majority of everyday situations.

How do I style a sapphire ring?

At Holdsworth Bros. Jewellers, we’ll help you style your blue sapphire engagement ring however you want. Our promise is to provide you with the help you need to turn your vision into wearable jewellery that will be cherished for years to come.  

Can I use diamonds and sapphires in the same design?

Despite the higher price tag it creates, many choose to combine blue sapphires with diamonds. Usually, the ideal design is to prominently feature a blue sapphire and then surround it with smaller diamonds. 

Why are sapphires and diamonds a good match?

Because diamonds usually feature a neutral colour-palette, they create a contrast that accentuates the blue of the sapphire. Additionally, the diamonds fill in the otherwise plain space on an engagement ring band, giving the ring a fuller, more detailed look.
