Find the sapphire colour that feels like you
A sapphire engagement ring begins with a colour you want to live with. Our collection brings together different lab grown sapphire hues, allowing you to compare their character before choosing the shape and setting. Use the colour collections above for a focused selection, or browse across the full range below.
Rich blue or a lighter blue palette
For a classic, defined centre, explore our blue sapphire engagement rings. If you prefer a softer blue, discover the aquamarine blue sapphire collection. These pale blue stones are aquamarine-coloured sapphires, a different gemstone from mineral aquamarine.
Pink, golden yellow and pink-orange
Pink sapphire engagement rings introduce a rosy palette, while yellow sapphires bring a golden centre to the design. Padparadscha sapphire rings offer a blend of pink and orange. View the images for your chosen design and ask our team about the colour of the stone you are considering.
Compare each colour with your preferred metal
Platinum and white gold create a bright frame around a coloured stone. Yellow gold carries warmth through the design, while rose gold introduces a pink tone of its own. Compare the same sapphire colour in different metals before deciding: the setting changes the overall composition as much as the gemstone shape.
Choose the proportions and setting
A solitaire keeps attention on the sapphire. A halo adds a contrasting frame; a trilogy creates a wider composition across the finger. Check the gemstone dimensions in millimetres, the band width and the specification of any accent diamonds on the individual product page. Carat weight alone does not describe how a finished ring will look.
A considered choice for everyday wear
Sapphire ranks 9 on the Mohs scale, making it resistant to scratching, although a ring still needs protection from knocks. Remove it for heavy manual work and follow the care advice for the complete piece. If you are deciding between colours or settings, our team can help you compare the options and confirm the details of your preferred ring.

Should I choose a sapphire colour before the setting?
Colour is a useful starting point. Compare the available colour collections and actual stones, then assess shape, metal and mounting together.
