Precious Stones

To help you understand a little more about precious stones, we’ve put together a collection of useful facts to help you buy with confidence.

- Rubies belong to the Corundum family, these mineral (inorganic) gemstones are defined by their shared chemical properties (such as having the same hardness on Moh’s Scale) but they can come in various colours.
- Rubies are durable and heard wearing - perfect for everyday use.
- The colour of a ruby will vary between pale red to dark purple red, however, heating the stone will improve the colour and clarity.
- The most expensive and rarest colour of ruby is deep red with a hint of blue and is called ‘Pigeon’s Blood’.
- Rubies are the birthstone of July
- Rubies are the traditional gift for a 40th wedding anniversary.
- Many people believe that rubies possess healing properties and are said to encourage good health and a long life.
- Rubies are perfectly complimented by both yellow gold and white metals which bring out the beautiful red hue.
- Aftercare: rubies are suitable for cleaning in ultrasonic cleaners and dips. However, rubies must not be subjected to heat during jewellery repairs so should be removed or protected during the process.

- Another member of the corundum family, sapphires are very durable and hard wearing and can come in various colours including pink, yellow, green, orange and white.
- Choosing the right sapphire is entirely down to personal choice – your favourite shade or colour may not be the most valuable but in this instance, beauty is very much in the eye of the beholder.
- Sapphire is the birthstone for September.

- Emeralds are often cut in a specific rectangular or square cut known as the ‘emerald’ or ‘step’ cut, which have cut off corners to protect the edges of this brittle gemstone while showing off the depth of colour.
- Emeralds measure between 7.5-8 on Moh’s scale, which means that it’s hard to scratch but it is brittle so it must be taken care of if it is to be worn on a daily basis.
- Emeralds are oiled to improve their colour and strength.
- The small marks (inclusions) and cloudiness that can sometimes occur are an accepted part of its appearance and are perfectly natural. It’s virtually impossible to find a completely clean emerald and they are sort after by collectors.
