Facts About Sapphires
Sapphires are a variety of the mineral Corundum, or crystalline aluminium oxide. Sapphires come in a wide variety of colours, except red. The red variety of Corundum is known as a Ruby. Strictly speaking the term ‘Sapphire’ refers exclusively to Blue Sapphires, any other colour of Sapphire are referred to as ‘Fancy Sapphires’. The traces of the elements titanium and iron cause the gemstone to be blue creating a ‘Blue Sapphire’. The more iron the stone contains the darker the colour of blue the gemstone will be. The trace element Chromium is needed in order for the stone to be either red or pink. When the stone is pink it is classed as a ‘Fancy Sapphire’ and when the gemstone is red it is classified as a Ruby. Other trace elements such as copper and magnesium give the gemstone its other colours.

What to look for in a Sapphire
When looking for a fine quality Sapphire you should consider the 4 C’s, much in the same way as you would for other gemstones. As with Rubies and Emeralds, colour is the most important factor to consider when determining the value of a Sapphire.
- Colour – Wikipedia defines the colour of a fine quality blue Sapphire this way: Blue Sapphires that are less valuable have a greenish or greyish hue to them. Fancy Sapphires come in a wide range of colours but generally speaking the more vivid the colour and the deeper the saturation of hue the more valuable the gemstone will be.
The color of fine blue sapphires may be described as a vivid medium dark violet to purplish blue where the primary blue hue is at least 85% and the secondary hue no more than 15%, without the least admixture of a green secondary hue or a gray mask.
- Cut – The finished cut of a Sapphire is generally dictated by the shape of the gemstone in its rough form. Because the most common rough form of Sapphire is barrel shaped, the finished gemstones are usually deep cut. The cut should emphasise the Sapphire’s beautiful colour without compromising too much of the weight.
- Carat – Sapphires come in all sizes from tiny gemstones right through to hundreds of carats in weight. Large fine quality Sapphires demand a higher price per carat the larger they get.
- Clarity – Usually inclusions within a gemstone affect the stone’s value negatively. Yet GIA reports that: The reason for this they say is:
inclusions can actually increase the value of some sapphires.These Sapphires are called Star Sapphires and the inclusions cause rays of light to be reflected. When you look into a Star Sapphire you may see several rays of light, giving the gemstone the appearance of containing a star.
They scatter light, causing the coveted visual effect without negatively affecting the gem’s transparency.
How to Clean Your Sapphire Jewellery
Sapphires are a very durable gemstone and are easy to look after. They are one of the hardest gemstones there are and can withstand daily wear.
Sapphires can be cleaned with a steam cleaner or ultrasonic cleaner and do not usually require any special care. Take care if you have a Sapphire that is fracture filled as this Sapphire may be more easily scratched. Generally though, you should be more concerned about damaging the metal that sets the stone than damaging the stone itself.
Sapphires can be cleaned easily at home with washing up liquid and a toothbrush. This will remove any residue or grease that may be dulling the gemstones shine. You could also soak the gemstone for 10-15 minutes in a cleaning agent specifically designed for cleaning jewellery.
