Sapphires, Rubies & Emeralds

Due to their strength and resilience to the everyday wear and tear; Sapphires, Rubies and Emeralds are by far the most common and popular choice of gemstone for engagement rings.

Gemstone Engagement Rings



Sapphires are the most popular coloured gemstone for engagement rings. Alongside the intense lustre and depth of colour, the structure of sapphires make them a great choice for an engagement ring that is equal parts alluring and enduring. Reaching 9 on the Mohs scale of hardness, the gemstone is second only to diamonds in durability, its resistance to chipping and scratching making it suitable for everyday wear. Learn more about sapphires, why the gemstone is suitable for engagement rings, and sapphire engagement ring design inspiration.

Sapphire Engagement Rings



Emeralds are distinct, verdant green gemstones, and are a more unusual choice for gemstone engagement rings. Emeralds are a little softer than sapphires and rubies, ranking 7.5-8 on the Mohs scale, yet their lush and exotic appeal give them a notable charm, ideal for a unique engagement ring. Explore emerald engagement rings designs we love, learn more about the origins of the gemstone and discover how to choose the most ideal emerald for your engagement ring.

Colour Is Key

Choosing a gemstone for your engagement ring 


Diamonds are undoubtedly the most traditional choice for engagement rings, yet with increasing interest from those in search of more unique and personal designs, precious gemstones are becoming a firm favourite amongst engagement ring buyers. Gemstones offer the chance to inject bold, strong or subtle and elegant colours into your design.

When it comes to selecting gemstones such as sapphires, rubies and emeralds, colour is an important factor to consider. Emeralds are inherently green and rubies red, yet sapphires can be found in a whole spectrum of colours, as well as the most widely recognised cornflower blue.

Typically, gemstones are more favourable and valuable the more vivid the colour, so when looking at blue, red and green gemstones, our experts advise opting for strong tones that are consistent throughout the spread of the stone. Despite this, many have a preference for more subtly toned gemstones, such as soft peach and pink sapphires and pale purples. Connect with one of our experts to learn more.
