Diamonds

Choosing the perfect diamond is essential when designing an engagement ring. With various options in diamond quality, shape, and origin, selecting the right one can be overwhelming and we are here to help. We specialise in certified, ethically sourced natural and lab-grown diamonds, ensuring superior brilliance and value. Whether you prefer a classic round cut or a unique fancy shape like oval, princess or asscher, our expert guidance will help you make the right decision. Explore our diamond collection and consult our diamantaire specialists for personalised advice. Explore our informative diamond page or contact our team.

Natural Diamonds

Natural diamonds are highly sought-after for their brilliance, rarity, and timeless beauty. As a symbol of luxury and love, they make perfect engagement rings, jewellery, and investment pieces. Our ethically sourced natural diamonds offer unmatched durability and value. 

Our diamonds are ethically sourced from countries like Canada and are typically cut in India and the USA. We provide diamond certification and laser engraving of the serial numbers onto the diamond for your assurance and trust.

View our Diamond Vault and search over 30,000 certified diamonds; visit our shops or contact us for information.

Lab-Grown Diamonds

Lab-grown diamonds are chemically identical to natural diamonds and form an excellent alternative to mined gemstones. We often compare them to man-made ice in your freezer and natural ice in a glacier. The material is chemically identical, and it is impossible to view the difference without expensive equipment. This makes them perfect for saving a significant amount with no downside.

We supply Lab-Grown Diamonds in any shape and quality, all with excellent cuts for the best sparkle possible. Like the natural equivalent, every stone is laser engraved and certified for diamond colour, clarity, cut and carat weight. The price point is about 1/4 the natural equivalent, and being made in a laboratory has a ‘green/ethical’ attachment. We offer a base quality that is very high at D-F colour, VS clarity and Excellent cut, meaning it will sparkle across the room – perfect. Please view our selection or contact our team.
