Suite 23, 2nd Floor, 28 Greville St, EC1N 8SU
Ranked #81 of 305 on 78 analysed reviews, every one five star across nearly ten years. A quiet Greville Street suite whose consultation travels to you. Check the week before you go: Saturdays are closed.
The Consultation That Travels
Promise Diamonds work from Suite 23 on the second floor of 28 Greville Street, with engagement rings across the standard shapes, his-and-hers wedding rings sold as matched pairs, and one service almost nobody else in the quarter offers: a let-us-come-to-you consultation at your home.
Google shows 79 reviews, and every one of them is five star, across nearly ten years. Eight arrived in the past twelve months, and they reply to around a third.
The reviews are short notes on price, service and quality rather than long stories, which fits a quiet suite that trades on referrals. An award-winning-designs page on the site carries the house’s design credentials.
Ten years without a review below five stars, and a consultation that comes to your sofa if the quarter feels too far.
