Durability Is Key When Choosing Coloured Gemstones

When making an engagement ring, gemstones can be a great alternative to diamonds, however not all gemstones are suitable for everyday wear. You need one that is durable and that will retain its beauty for years to come.

The Mohs Scale of Hardness

As a jewellery designer, durability is very important. Gemstone engagement rings are designed with gemstones graded on the Mohs scale of hardness, which tells us the level of resilience of one particular stone from another. 

This scale consists of ten classifications with diamonds being rated the hardest at 10 and talc the softest at 1. Everything else falls somewhere in between.

Putting this into context, your fingernail rates as 2 while a piece of glass rates at 6 or 7. 

Gemstones I Recommend For Engagement Rings 

I recommend considering strength, beauty and hardness when choosing a gemstone. Different coloured gemstones have very different hardness values and it is important to know this before choosing one. 

Of course, diamonds are the obvious choice for durability and, as there are many choices of coloured diamonds, these are the ideal option for a gemstone. 




   Sapphires rate at 9 on the Mohs scale and make stunning                      diamond alternatives as well as offering an impressive splash of        colour. Due to their affordable price point, choosing a sapphire        allows you to choose a larger centre stone, of any shape or cut.








Pear Shape Rubies

Rubies also rate at 9 on the Mohs scale and make a sophisticated and classic centre stone choice. Their deep red colour symbolises love, suits all skin tones and looks particularly good when set in rose gold.






With their rich green hues and distinguished           history, an emerald makes a fantastic choice for                  an engagement ring. While its low facet structure       results in a less brilliant stone, it does showcase its     prized and distinguished colour.

However, it is important to note that an emerald         scores 7.5 - 8 on the Mohs hardness scale, meaning             that it is more likely to be damaged, so keep this in         mind if choosing an emerald engagement ring.



Coloured stones are appealing on many levels but be aware that durability is key if you want your ring to last a lifetime.
