What is a European shank engagement ring?
A Euroshank engagement ring features a subtly squared or flattened base of the band, rather than a fully round profile. This intelligent design improves balance and stability, helping the ring sit upright on the finger and reducing unwanted rotation. It is especially effective for engagement rings with larger or top-heavy centre stones.
Core Characteristics
Design Approach: Integrated into the band, not an external attachment
Profile: Round on top for comfort and aesthetics, gently squared or flattened at the base
Purpose: Minimises spinning and keeps the centre stone facing upward
Key Advantages of the European shank style
- Improves stability for rings with large or elevated stones
- Keeps the engagement ring visually aligned and upright
- Enhances comfort without bulky additions
- Offers a refined, contemporary alternative to sizing beads

The band’s flat surface prevents the ring from spinning on the finger. This is a common issue with traditional shank rings. The euro Shank is typically seen in contemporary designs but can also be incorporated into more traditional styles.
Ideal Use Cases
- Engagement rings with heavier centre stones
- Fingers where the knuckle is wider than the base
- Wearers frustrated by constant ring rotation
- Designs requiring long-term comfort and balance
Benefits of a square bottom engagement ring
One of the primary benefits of a European shank engagement ring is comfort. The band’s flat surface prevents the ring from twisting on the finger, reducing discomfort and irritation. The raised edge or rim provides extra support. At the same time, it prevents the ring from sliding around the finger. As a result, the risk of the ring catching on clothing or other objects is reduced. Moreover, the squared-off shape of the euro shank band adds a unique, modern look to the engagement ring.
In our opinion, the squared effect adds a contemporary look and feel to traditional engagement ring designs. For this reason, it is an ideal choice for those seeking a unique piece of jewellery.

Adding durability with a contemporary shank ring
Another advantage of this band style is its durability. The extra metal used to create the raised edge or rim on the euro shank band increases the ring’s durability. The added metal creates a stronger, more secure band. As a result, it can withstand daily wear and tear, making it a long-lasting choice for an engagement ring.
Additionally, the band’s flat surface helps keep the diamond in place. For this reason, the band is less likely to spin around the finger. This added security ensures that the diamond remains in place, reducing the risk of it falling out or becoming damaged.
Practical Considerations
- Slightly increases metal weight and craftsmanship time
- Requires precise sizing for optimal comfort
- Can be adapted to both modern and classic ring styles
Disadvantages of the European band are worth consideration
However, Euro Shank engagement rings have some downsides. Sizing may be an issue, as the euro shank is a modified version of the traditional shank. This can make it challenging to size correctly, particularly if the ring is custom-made or has a unique design.
It is important to have the ring professionally sized to ensure a comfortable and secure fit. Moreover, the increased thickness and weight of the raised edge or rim can increase the cost of the engagement ring.
Furthermore, most of our European shank engagement ring styles take form through our bespoke design service. As a result, most rings custom-made this way command a premium over standard ring styles.
Additionally, the euro shank design is less widely available than traditional shank designs. For this reason, fewer styles exist from which to choose. For this reason, as noted above, we provide such designs through our bespoke engagement ring service.
Square shanks offer a unique and modern design while providing added comfort and durability for the wearer.
The raised edge or rim on the band provides additional support. In addition, it helps to keep the diamond in place, ensuring the ring remains secure and comfortable to wear.
While there are some downsides to squared band engagement rings, such as sizing and cost, they remain a popular choice. For anyone looking for a modern take on the traditional ring, this unique feature applies to many ring styles.
Euro Shank Square Wedding Rings
We created a shaped Euro shank square wedding ring as part of the bespoke ring set. In fact, the accompanying band was a square wedding band styled to fit perfectly with the engagement ring.
We created both rings using CAD, working to our clients’ requirements to achieve the perfect pair.
