Diamond Engagement Rings – Crafted for a Lifetime by Blacklock
At Blacklock, an engagement ring is never just jewellery; it’s a lasting symbol of your story. Our collection of diamond engagement rings is handcrafted in London, designed to celebrate love with exceptional materials, precise proportions and natural beauty.
With over 190 years of experience in working with natural diamonds, our rings are created with purpose. From classic solitaire engagement rings to striking halo settings, each design is made to last a lifetime and beyond.
What Sets Blacklock Engagement Rings Apart?
We believe that an engagement ring should carry meaning. It should feel right on the hand and speak clearly to the heart. At Blacklock, every stone is selected for its brilliance, cut, and origin, and every setting is designed to enhance its natural character.
Choose from a curated selection of shapes and styles, including the round brilliant diamond, oval cut, emerald cut, baguette cut, and princess cut. Each is set by hand to ensure detail and precision in the finish and to ensure that each stone is presented in the best way possible to maximise its brilliance. We also believe that by doing this we honour the emotion behind it.
We use only ethically sourced diamonds and certified precious materials, because provenance matters. Our team works exclusively with partners who meet strict standards for responsible sourcing and environmental care.

How to Choose the Perfect Engagement Ring
Finding the perfect engagement ring is a personal journey and one we help you navigate with clarity and confidence. Start by considering:
- Stone shape – from the classic round brilliant to the elongated oval, or the clean lines of an emerald cut
- Setting style – a minimalist solitaire, a delicate halo, or a modern three-stone
- Precious metal – choose between platinum, yellow gold, or rose gold
- Ring size and proportion – designed for comfort and daily wear
- Design detail – such as split shanks, textured finishes or understated pavé accents
You don’t need to know everything. You only need to know what feels right. We’ll help with the rest.
