Yes, men can and do wear engagement rings. Though traditionally worn by women, the decision to wear an engagement ring is entirely up to the individual. Regardless of gender, an engagement ring symbolises the love and commitment one has for another.

An engagement ring typically features a prominent stone and is presented during a marriage proposal, while a wedding ring has a simpler design and is exchanged during a wedding ceremony. Traditionally, an engagement ring is worn by one partner as a symbol of the promise to marry, while wedding rings are worn by both spouses as a sign of their union. For more information, explore our wedding ring guide.

The way you wear your engagement and wedding rings together depends on the design of each ring. When selecting your wedding ring, it is important to consider the design of your engagement ring to ensure your wedding ring will both complement and sit comfortably alongside your engagement ring. If you’d like some guidance, feel free to book a consultation with our friendly client service team or learn more from our guide on how to find the perfect wedding band pairing.

We offer a selection of ethically sourced gemstones in our engagement rings for women and in our men's engagement rings, including:

Each gemstone is chosen for its quality and sustainability, ensuring your ring is both beautiful and responsibly made. Whether you’re after a scarlet red lab-grown sapphire that mimics the look of a ruby engagement ring or a clover green lab-grown moissanite that resembles an emerald, begin your journey today by exploring our wide range of engagement rings. For more information and guidance on which gemstone is best for you, dive into our gemstone guide.

The price of engagement rings at Cullen varies based on factors such as the chosen gemstone, carat weight, and setting design. We offer a range of designs to suit different budgets, and our team can help you find or create a ring that meets your preferences and price point.

To maintain the brilliance of your diamond engagement ring:

Clean it regularly with mild soapy water and a soft brush.
Avoid exposing it to harsh chemicals or abrasive materials.
Store it separately to prevent scratches.

Proper care will keep your ring looking its best for years to come. For more information, check out our ring care and ring cleaning guides.
