We’re a family-run jeweller on Greville Street, in the middle of Hatton Garden. Everything we sell we can explain, because we make and set it ourselves rather than ordering it in. You’ll deal with the same people from the first conversation to collection, and you’re welcome to take your time — there’s no commission-driven sales floor here. We have over 300 reviews on Trustpilot if you’d like to hear it from our customers rather than from us.

Yes. Our workshop is here in Hatton Garden and your ring is made on our own bench. That means we can adjust a setting, change a shoulder, alter a profile or work to a sketch you bring in — and if something needs tweaking after you’ve collected it, it comes straight back to the people who made it. It also means we can show you a stone loose, in the light, before it goes anywhere near a setting.

Yes, we sell both natural and lab grown, and we’ll talk you through the difference honestly. A lab grown stone is chemically and visually the same as a natural one; the difference is how it was formed and what it costs. For the same budget, lab grown usually buys you a noticeably larger or higher-quality stone. Natural holds its value differently. Neither is the right answer for everyone — come in and look at both side by side.

Usually two to four weeks from the design being agreed. Simpler settings can be quicker and more involved pieces take longer, particularly if we’re sourcing a specific stone. If you’re working to a date, tell us at the first appointment and we’ll be straight with you about whether it’s achievable.

We do. We buy scrap and broken gold in any carat, diamond jewellery, antique and estate pieces, and signed designer names including Cartier, Tiffany & Co., Van Cleef & Arpels, Harry Winston, Graff and Boodles. Valuation is free and there’s no obligation to sell. Send us a photo on WhatsApp first and we’ll give you an idea of value before you travel.
