Gemstones have an uniquely intoxicating character all their own and come in a tantalising array of colours that make your jewellery radiant, distinctive and beautiful. 



A rare beauty

Gemstones are rare. They have been created deep in the earth’s core, through heat and stress over many, many millions of years. They are found in the harshest of places on earth from emeralds in the steaming heat of Colombia to diamonds in the baking sun of southern Africa. 

The stones and their colours

With gemstones, the array of colours is virtually limitless. 


The ‘Prince of Gems’. Diamonds are the ultimate stone. Hard, durable, beautiful and with an unmatched sparkle.

Rubies and sapphires

The wonder of rubies and sapphires is they can be tailored to taste.  They offer a range of beautiful blues or ravishing reds yet there are yellow, pink and violet sapphires, too. 


The emerald’s green is intense yet it’s a brittle, more fragile stone. Which is why the emerald-cut shape was developed to protect it.


Found only in Tanzania, the tanzanite marries purples and blues. Tender and tantalising. 


A rainbow of colours - red, marmalade orange and the intense green of tsavorite. Garnets are generally un-treated and more affordable. 


Radiant in its shades of purple, legend has it that this durable member of the quartz family can protect against drunkeness! 


Citrine is a quartz, the pale yellow to brownish-orange cousin of amethyst. Its attractive colour, durability and affordability makes it the favourite yellow-orange gem. 


Pearls are a delicate, natural, organic mineral, beautiful and shimmering with a shiny lustre created by the mollusc host where they are grown. They are best worn or stored well away from other stones.


From pinks to oranges, topaz comes in an explosion of colour, the most famous being sky blue. 


Opals are unique for their sheer play of colour. As cabochons, the curved surface helps this less durable stone survive knocks and scrapes.


Peridot is a uniquely apple green vitreous stone. The play of greens and small black inclusions surrounded by a halo give it its affectionate name of ‘Lily Pad’.


As the name suggests, aquamarines were once thought to come from the sea, but the actually belong to the emerald family. Their long parallel-needle inclusions are colloquially known as ‘rain’!


Tourmaline comes in green, blue-green, mint, yellow and even dusky pink.
