• Diamonds and more

More than diamonds

Our website is crammed with all the information you’ll ever need when it comes to choosing the perfect engagement ring – and anything you can’t find on the site is certainly included in Lewis Malka’s best-selling book The Engagement Ring.

But we’ve got a lot more to offer, too.

Whether it’s a unique personal gift, a jewellery repair, a valuation or a public speaker you need, we’ve got it covered.


No matter how much we try to look after the items of jewellery we own, they do sometimes become damaged, and it’s vital any repairs are carried out by an experienced jeweller who knows what he or she is doing.

From broken clasps on chains to new claws on rings, there isn’t a jewellery repair we haven’t seen before in the 25 years we’ve been around, so you know your precious item is in safe and trusted hands when it comes to restoring it to its former glory.


Like all fashion, jewellery can become outdated and when it does, a piece that was once a permanent fixture of day or evening wear is consigned to the depths of a jewellery box or drawer.

With a bit of imagination and a lot of expertise, these fine old heirloom pieces can be remodelled to become more contemporary and wearable, meaning they can once again be part of your style for today without compromising their sentimental value.

Valuations & Reports

The value of jewellery isn’t static, which is why insurance companies recommend you have it checked and valued every few years – yet it’s something that often slips people’s minds when they come to renew contents policies.

Ensuring your jewellery has a relatively recent valuation report gives you the peace of mind that comes with knowing its current value is protected should the worst happen – and there’s always the possibility that a piece is actually worth far more than you thought.

Gifts for Birthdays, Anniversaries and Special Occasions

If you’re looking for the perfect gift to give, we’ve got plenty of ideas to set you on your way. From a chain or cufflinks for him to earrings or a pendant for her, there’s a good chance we’ve got the ideal gift whatever the occasion.

And if we don’t have it in stock, we can source it for you.

Luxury Watches

We buy and sell luxury brand watches at a fair price, so if you have a watch to sell or you’re looking for a high-end watch to buy, we can help.

Public Speaking

Looking for an after-dinner speaker who’s got something a little bit different to offer? Lewis Malka is a veteran of Hatton Garden with a passion for diamonds and a ready wit that will enthral your guests and light up your event.

Lewis takes his audience on a journey filled with anecdotes that tells the history of diamonds, examines the romance of them, explains how they became as valuable as they have and why we use them to propose.

Corporate Services

If you're looking for a training event with a difference, Lewis' team building sessions are built around diamonds, getting teams to handle the stones, learn the 4Cs (colour, cut, clarity and carat) that govern their value and quality and work together to solve challenges along the way.
