Depth of knowledge leads with 15 mentions, the bespoke and design process follows on eight, and seven reviewers each describe patience with questions and being kept informed throughout. Six say the ring exceeded expectations.

Nothing sits below four stars, and a fifth of reviews carry a reply.

For scale: that record sits in the top 1 per cent for the share of reviews at four stars or better. In plain terms, you should be in safe hands here.

I can’t recommend Danyal enough! From the very beginning, he made the entire process of designing my dream wedding ring feel so easy, smooth, and genuinely exciting. He really took the time to understand exactly what I wanted, and then somehow managed to elevate it even beyond what I had imagined.”

Danyal deserves a 10* review is that was possible. He has been SUPERB throughout the entire process. Danyal made a Picky customer like me who is very much specific to what she wants extremely HAPPY.”

Who this suits

The Right Buyer for A Star Diamonds

This suits a buyer who wants the Exchange experience: walk-in, direct, trade-floor pricing talk, with a family across the counter rather than a sales rota. The seven-day week includes Sunday afternoons.

Less suited to anyone who wants a private consultation suite; the Exchange is a working floor, and that is its character and its value.
