Whether you seek important jewels, rare pre-owned jewellery, or a one-of-a-kind luxury jewel of your own creation, we’ll turn your wishes into reality.
We have impeccable international connections and are experts at sourcing statement jewellery to order. From Bulgari, Cartier, Van Cleef & Arpels, and Tiffany & Co. to loose diamonds, sapphires, emeralds, rubies and more, simply tell us the jewels you desire, and we will find them.
We welcome enquiries from discerning clients looking to buy or sell jewellery or loose gemstones, so do get in touch for a free, no-obligation chat. We’ll be transparent about our services, fees, and what we can achieve. And if we’re not the perfect fit for your needs, we’ll steer you in the right direction.
In-person or online appointments are arranged at your convenience and preferred location. As a bespoke jewellery dealer in London, we cover the UK in its entirety. For clients further afield, our personalised jewellery dealer services extend internationally to Europe, North America, the Far East and beyond. No matter where you are, we are here to help you.

“At Janus, we are guided by beauty.
Everything we handle is genuinely special and the best of its type.
Undeniably, these are jewels of considerable value,
But in the perfect stone, there is more magic than money.
With that comes responsibility: we are both custodians and matchmakers.”
