Single Stone Moissanite Engagement Rings

Solitaire engagement rings are one of the most classic ring styles of them all due to their simplicity and beauty. Originating from the Latin word ‘solus’ meaning ‘alone’ or 'sole’, solitaire rings feature just one single diamond or gemstone.

Here at Ethica Diamonds, around 60% of the total engagement rings we sell each year are solitaire. The style has been around for centuries and loved by most so it means the likelihood of them going out of fashion is very slim. They also make a great option for those partners seeking an engagement ring for a loved one if they don’t know the preferred style.

Because solitaire engagement rings feature only one stone, solitaires are a great style for showing off unique or larger gemstones and diamonds. 

This beautiful collection is set with the Ethica Diamond, our signature gemstones. These gems offer the same toughness and longevity as diamonds and have the additional benefit of being considerably less expensive. They are also independently certified, to international standards by the GRI or IGI.  

Ethica Diamonds are produced using an exclusive patented technology and made from premium grade moissanite with a lab diamond infusion. They are cut and fully faceted to exact diamond proportions and posess incredible depth and realism, radiating sparkle and brilliance comparable to the most expensive diamonds that will last forever.
We stock these stones at consistent E colour, VVS1 clarity and excellent cut so all Ethica Diamonds have these specifications. 

We can offer other colours in our signature moissanite such as champagne, blue, green and many others, and these are offered alongside our coloured gemstones or fancy cut lab grown diamonds. 

When it comes to choosing your solitaire engagement ring, moissanite is an excellent option because they are more ethical and sustainable. Another advantage of moissanite is their affordability. Moissanite are priced lower than diamonds, allowing you to get a larger or higher quality gemstone ring for your budget. They come in a wide range of cuts and sizes, so you can find the perfect solitaire moissanite for your engagement ring.

In summary, moissanite is a fantastic choice for a solitaire engagement ring. They offer the same beauty and aesthetics as diamonds while still being ethically and environmentally responsible. With the added benefit of affordability, moissanite allows you to have a stunning and socially conscious engagement ring that symbolises your love and commitment.

If you have something specific in mind, we can create your own bespoke engagement ring  that your future fiancé will treasure.

Frequently Asked Questions

What makes a solitaire moissanite engagement ring unique?

1. Moissanite's brilliance and sparkle: Moissanite has a higher refractive index than diamonds, which means it reflects more light and sparkles more intensely. This makes a solitaire moissanite engagement ring stand out and catch the eye.

2. Moissanite's durability: Moissanite is one of the hardest gemstones, with a Mohs scale rating of 9.25. This makes it very durable and resistant to scratches, ensuring the longevity of the ring.

3. Ethical and sustainable choice: Moissanite is a lab-created gemstone, which means it is eco-friendly and doesn't come from mining practices that may have a negative impact on the environment or labour practices. This makes it an ethical and sustainable choice for an engagement ring.

4. Cost-effective alternative to diamonds: Solitaire moissanite engagement rings are generally more affordable than diamond rings of the same size and quality. This makes them a great option for those who want a stunning and unique engagement ring without breaking the bank.

Can you design a bespoke solitaire moissanite engagement ring for me?

Yes! We can create bespoke jewellery that is unique to you. Whether you want to design your own piece of jewellery from scratch or put your own stamp on an existing design, our friendly and knowledgeable team are here to make it happen.

Your Ethica Diamond can be set in a classic six or four prong setting, which provides both security and an elegant presentation of the stone. The prongs can be delicate and minimalistic, allowing the gemstone to shine.

The band of the ring will be crafted from your preferred metal choice, such as 18k white gold, yellow gold, rose gold, or platinum. Each option offers a unique aesthetic and durability.

The band itself can be a simple, timeless design, complementing the brilliance of the centre stone. A slim, smooth band will draw attention to the gem while maintaining a sleek and elegant look.

Carat weight: The size of the Ethica Diamond is a personal preference. Depending on your budget and desired size, we can explore these options with you during a no obligation appointment. 

to add a personal touch, you may consider engraving a meaningful message or initials on the inside of the band.

Is a moissanite solitaire engagement ring a classic choice?

While solitaire engagement rings are traditionally considered a classic choice, moissanite is a relatively new and modern gemstone compared to diamonds. However, the simplicity and elegance of a solitaire setting combined with the brilliance of a moissanite gemstone can create a timeless and classic look. Its simplicity and timeless elegance make it a versatile option that never goes out of style. The focus on the gemstone as the centrepiece of the ring allows its brilliance to shine through, making it a symbol of lasting love and commitment. 

Is a moissanite solitaire engagement ring a safer, more practical choice?

A moissanite diamond engagement ring is considered a safer and more practical choice for several reasons

1. Simplicity: Solitaire rings feature a single gemstone as the centrepiece, without any intricate or delicate settings. This simplicity reduces the risk of small stones getting loose or falling out over time.

2. Durability: The single moissanite in a solitaire ring is typically set securely, reducing the chances of damage or loss. The strong and sturdy setting helps protect the gem, making it less prone to wear and tear.

3. Versatility: Solitaire rings are highly versatile and can be easily matched with different styles of wedding bands. This flexibility allows for easier customisation and future changes in style preferences.

4. Timelessness: Solitaire rings have a classic and timeless design that never goes out of fashion. They are not influenced by trends or fashion changes, making them a timeless and enduring choice.

Overall, a solitaire moissanite engagement ring offers practicality, durability, versatility and timelessness.
