5 Stunning Diamond Alternatives

September 1, 2018 / Coloured Gemstones, Diamond Education

Diamonds are the most popular gemstone for an engagement ring, however, there are many women turning their heads to colourful and often lesser-known gems. Incorporating colour into your engagement ring is a wonderful way to create a distinctly unique design. From the ever-popular blue sapphires to the softer, more earthy hues, there are plenty of options no matter how bold or how subtle you would like to go.

There are few rules when choosing a coloured gemstone for your engagement ring. It is all about what colour speaks to you and your partner. There are recommendations on which gemstones are most suitable for an engagement ring. Each individual stone is unique in its own way so it is always a good idea to have a professional eye look at a stone closely to determine if it is an appropriate choice for an engagement ring.

Let’s take a look at five great options to consider:


Sapphires are the most popular alternative to a diamond. They offer ideal durability coming in just one step below diamond on the Moh’s Hardness Scale. Famously known for the beautiful blue varieties, it is often forgotten that Sapphires are also available in many other colours such as pink, yellow, shades of green and black.



Morganite is one of the most beautiful and also lesser-known gemstones. This stunning gem is renowned for its exquisite blush peachy-pink tone. This gem belongs to the Beryl family and is also known for its brilliance and clarity. Morganite makes the perfect match for rose gold engagement rings.


Emeralds are one of the most prized gemstones, if you love Emeralds then you may not find any other gem compares. Although they are absolutely stunning, they can be extremely fragile, they are typically heavily included making them far more susceptible to chips and fractures. This doesn’t mean that they are ruled out for engagement rings but they should be chosen and handled with care. It is important to engage an expert to determine whether a particular Emerald is an appropriate choice for an engagement ring.


Black Spinels



In recent years, there has been an ongoing rise in the popularity of engagement rings featuring black gems. Many opt for black diamonds, however, it may come as a surprise to hear that black diamonds can be quite fragile in nature. For a striking and surprisingly affordable alternative which offers superior durability, we often recommend black spinels.


Rubies are the ultimate gemstone for those that love red. They represent love and passion and have long been used in engagement rings. They look particularly beautiful in vintage styles especially those set with small white diamonds for contrast. Rubies belong to the same group of gemstones as Sapphires, the corundum family, therefore, they are a desirable hardness for an engagement ring. It is important to have a professional help you choose an appropriate Ruby for an engagement ring. In recent years a treatment called ‘fracture filling’ has become increasingly common. This is when low-grade stones are enhanced by filling the tiny voids with lead glass during the heating process.
