What makes a ruby?
Ruby is the red version of the corundum mineral group – all other colour variations are classed as sapphire. A ruby is formed when traces of chromic oxide is present with a corundum crystal, giving the ruby its distinctive hue. The strength of the red colour is down to how much chromium is present; as little as 1% of the overall chemistry can produce a deep red.
The colour of a ruby can range from a pinkish red – as seen in this Victorian ruby and diamond ring – to a deeper, richer red, such as in this unusual oval cut ruby ring. Rubies with a deeper, richer colour tend to be more valuable.
What other features do they have?
Most other varieties of corundum are internally clean and clear, whereas rubies can be expected to have inclusions (internal imperfections).
Depending on whether these are large or small inclusions (often called ‘silk’), the cost and durability of the ruby will be affected. The ‘cleaner’ the stone, the more valuable it will be.
As it is incredibly rare to get an inclusion-free ruby, if you have a perfectly clear one it is a good idea to test it, as it may be synthetic.
