Blue Sapphire

Blue sapphires are the birthstone for September and symbolise fidelity, nobility and truth.

The sapphire is the hardest gemstone, measuring a 9/10 on the MoH scale of stone hardness. Blue sapphires come in many different shades of blue, the one shown here is a classic deep blue.

We source our blue sapphires from Sri Lanka and Thailand and will always set this stone in white gold or platinum to best bring out it's natural colour.


The aquamarine is the most popular of the semiprecious stones and is the birthstone for March.

As the name suggests, it is the gemstone for lovers of the sea and is said to give protection to the wearer.

Like the emerald, it is an 8 on the MoH scale of stone hardness and so should be worn with some care. Our aquamarines are set in white gold or platinum to best offset their delicate blue and we source our aquamarines from Sri Lanka, Thailand, Zambia and Mozambique.


Garnets are the birthstone for January. They are known for an association with love and vitality.

Garnets come in many different colours but they are best known for a deep, inky red.

The garnet is a 7.5 on the MoH scale and is suitable for everyday wear, it does not have any other specialised care requirements.

Our garnets are sourced from Canada, Sri Lanka, Thailand and the USA. Like rubies, our garnets are always set in white gold or platinum.

Pink Sapphire

Pink sapphires have been extremely rare throughout history and are now highly prized.

They have a range of meanings including love, delicacy, femininity and elegance.

Our pink sapphires are sourced from Sri Lanka and Thailand and we will always set them in rose gold.


In Sanskrit the ruby is known as 'the king of precious stones' and symbolises passion, wisdom and success. It the birthstone for July.

Our rubies are a deep red shade and are sourced from Mozambique and Thailand. It is also a hard wearing stone and a 9 on the MoH scale.

All rubies will have some inclusions and cloudiness due to their chemical structure and this is to be expected.

Our rubies are always set in white gold or platinum.

Yellow Sapphire

Yellow sapphires are known as bringers of happiness and good fortune as well as wisdom and prosperity.

Like pink sapphires they are extremely rare and increasingly popular as a unique choice for jewellery and engagement rings.

Our yellow sapphires are sourced from Australia, the USA, Sri Lanka and Thailand and will always be set in yellow gold.


Emeralds are the May birthstone and symbolise peace, balance and loyalty. They have featured in a number of famous marriages, some more peaceful than others, including Jackie Kennedy, Grace Kelly and The Duchess of Windsor.

Our emeralds are sourced from Zambia and we look for a rich, deep green with minimal inclusions and great life and clarity. We set our emeralds in yellow gold to best bring out the depth of their green. All emeralds will have some inclusions and this should be expected.

Emeralds are a delicate stone and should be worn with more consideration than a ruby or a sapphire.


You may have heard of the 4 C's but a similar scale does not exist for coloured gemstones.

Instead, these require an individual assessment by someone trained in gemology who can assess a far wider range of factors including hue, saturation stability and colour depth making the assessment of the quality and value of coloured gemstones highly complex and specialised.

At Fenton & Co we hold ourselves to a rigorous set of internal set of standards and evaluate each and every gemstone individually to assure that we are upholding our quality standards.


All of our gemstones are natural and as such will have the associated characteristics such as inclusions. Inclusions appear as small lines or clouds within the gemstone and are created during formation when surrounding minerals enter the stone.

Inclusions are present in all gemstones, although not always visible, this is known as being 'eye-clean'. The likelihood of a gemstone being eye-clean depends on the type of stone, for example it is far rarer to have an eye-clean ruby or emerald than a sapphire.

If an eye-clean appearance is very important to you then we recommend you consider aquamarines, garnets and sapphires.

Gemstone Treatments

There are a number of new chemical treatments that are available which are commonly used by many jewellers today.

At Fenton & Co we follow the same standards as leading luxury jewellers and do not accept any treatments that may destabilise or adversely accept the gemstone in the long run.

We will only accept heat treatment for sapphires or rubies and clear oil for emeralds as these will only improve the appearance of your gemstone and remain stable over time.
