Frequently Asked Questions

How long have halo or cluster diamond engagement rings been around? 

Cluster diamond engagement rings have been around for several decades, but their history extends much further. The cluster setting, where multiple smaller diamonds are grouped closely together to create the appearance of a larger stone, has been used in jewellery for centuries.

In the 18th and 19th centuries, cluster rings became popular as a cost-effective alternative to larger, more expensive solitaire diamond rings. These rings showcased the beauty and brilliance of smaller diamonds while providing a similar visual impact.

As time progressed, cluster diamond engagement rings continued to evolve in design and popularity. Today, they are a popular choice for those seeking a unique and eye-catching engagement ring and so the halo design has gained in popularity. The versatility of these settings allows for various designs and arrangements, from floral-inspired clusters to more delicate halo patterns.

Halo diamond engagement rings have remained popular throughout the years and have gone through various iterations and design adaptations. They continue to be a popular choice among those seeking a classic, glamorous, and eye-catching engagement ring.

Is a halo engagement ring unique? 

Halo engagement rings can be a more unique option than a traditional solitaire, since the halo can add an additional element of individuality, for example by using coloured gemstones or less traditional setting styles. It features a centre diamond surrounded by a "halo" of smaller diamonds or gemstones. This design creates a stunning and eye-catching effect, making the centre stone appear larger and more brilliant. The halo also adds extra sparkle and enhances the overall beauty of the ring. Additionally, these pretty designs are available in a variety of styles and can be customised with a coloured fancy diamond or halo gemstones to fit the wearer's preferences, making each ring truly unique and special.

Is a halo diamond engagement ring easy to pair with a wedding band?

Halo diamond engagement rings can be quite versatile and the shape and design of the halo can affect how well it pairs with a wedding band. Some halo diamond rings have a more curved or scalloped halo, which may require a curved wedding band to create a seamless look. Similarly, a flat or flush halo can typically be paired with most standard straight wedding bands.

It is also possible to find matching or coordinating wedding bands specifically designed to complement halo diamond engagement rings. Ethica offers a stunning collection of bridal sets where the wedding ring is made to fit perfectly with the shape and design of the engagement ring, creating a cohesive and stunning bridal set.

Are there any risks in choosing a halo diamond engagement ring?

Yes, there are a few risks to consider when choosing a halo or cluster diamond engagement ring. While these risks exist, they can be mitigated with proper care and maintenance. Regular cleaning, routine inspections, and being cautious by removing your ring whilst doing physical activities can help minimise these factors.

1. Prong wear: If the halo diamonds are exposed, they can be prone to damage through daily wear and tear. Since they are smaller and set in a more delicate way, they may be more susceptible to being knocked causing chipping or loosening.

2. Careful resizing: In case you want to resize the ring in the future, it can be more complicated and potentially costly with a halo ring, especially if it also has shoulder-set diamonds. Since there are more diamonds, resizing it could require additional work or even resetting the melée diamonds, as they can move ever so slightly within their setting.

4. Upkeep and maintenance: The intricate design of a halo setting can make maintenance and cleaning slightly more challenging compared to a simple solitaire setting. The small stones in the halo can trap dirt and debris more easily, requiring professional regular cleaning. It's important to factor in the additional time and cost involved in maintaining the ring's sparkle and brilliance.The halo diamonds may also require regular maintenance and tightening to ensure they stay securely in place. It's essential to have the ring inspected periodically to address any potential issues proactively. Ethica offers a not for profit Ring Maintenance Service helping you keep your halo diamond ring in perfect condition.

How do I choose the right metal for my halo engagement ring?

Selecting the perfect metal for your halo engagement ring is an important decision, and Ethica Diamonds is committed to offering ethically sourced and sustainable options.

Ethical and Sustainable Sourcing:

Recycled Precious Metals: We prioritise using 100% recycled precious metals whenever possible. Our gold is often certified by the SCS Recycled Gold Standard V7-0, ensuring responsible sourcing and conflict-free diamonds. This guarantees the metal is eco-friendly and avoids contributing to environmental damage.

Fairtrade Gold: We are registered Fairtrade Gold jewellers, supporting small-scale miners and their communities through fair trade practices. This ensures ethical gold and environmental protection within the gold mining industry.

Matching Your Style and Existing Jewellery:

Coordinating with Other Jewellery: Consider the metals you wear most often. If you favour silver jewellery, white gold or platinum might complement your halo ring better.

Engagement and Wedding Ring Compatibility: Engagement and wedding rings are often worn together. Choose the same caratage of gold or platinum for both to avoid uneven wear. Mixing metal colours is possible, though.

Metal Properties:

Platinum vs. White Gold:
Appearance: Both offer a similar white shine, with platinum being slightly "greyer" and white gold slightly warmer.
Durability: Platinum is denser and more durable, making it a good choice for long-lasting engagement rings.
Hypoallergenic: Platinum is naturally hypoallergenic, ideal for those with sensitive skin.

Yellow Gold:
Classic Choice: Yellow gold is a timeless and traditional metal, perfect for those who prefer a warmer aesthetic.
Maintenance: Requires periodic polishing to maintain its shine.

Additional Considerations:

Skin Tone: Yellow gold generally complements warmer skin tones, while white metals like platinum or white gold suit cooler skin tones.

Budget: Platinum is typically more expensive than gold, while the price of gold varies depending on karat.

Ethica Diamonds offers a variety of ethically sourced and sustainable metals for your halo engagement ring. By understanding these factors and exploring our collections, you can make an informed choice that aligns with your style and values.
