Queensmith
The showroom experience
Queensmith is the jeweller most people picture when they imagine visiting Hatton Garden. A proper showroom at 98 Hatton Garden with display cases, knowledgeable staff, and an on-site workshop where you can watch rings being crafted.
The consultation is hands-on. You try rings on, compare metals against your skin tone, and look at diamonds under a loupe with a gemologist. The staff take time to explain without trade jargon, and they genuinely do not rush you. Walk-ins are welcome Monday to Saturday — no appointment needed, which makes them ideal for couples who want to browse together without committing to a formal meeting.
Their bespoke service is a genuine strength. They design in-house using CAD, manufacture in their own workshop on the premises, and turnaround is typically 4-6 weeks. If watching your ring being made is part of the experience you want, Queensmith delivers that in a way very few Hatton Garden jewellers can.
Where Queensmith is less strong is online transparency. You cannot browse their full diamond inventory or see prices on their website before visiting. The experience is designed around the consultation — which is brilliant if you want to be guided, but less ideal if you are the type of buyer who wants to do extensive research independently first.
Queensmith strengths
- Walk-in friendly — no appointment needed
- On-site workshop — watch your ring being made
- Hands-on consultation with physical try-ons
- 4.9 Trustpilot rating — exceptional reviews
Queensmith limitations
- No online pricing — must visit or enquire
- Smaller searchable diamond inventory
- Premium pricing reflects showroom costs
- Less suited to independent researchers
MOH London
The technology-first approach
MOH London represents a different philosophy entirely. Their model is built around doing the research online first and visiting in person to confirm. Their ring builder tool gives you access to over 1,000,000 GIA and IGI certified diamonds — with full specs, certification details, and prices shown before any conversation happens.
This approach suits a particular kind of buyer: someone who wants to understand every option, compare dozens of stones by spec, and arrive at their consultation having already made most of the decisions. The in-person appointment at 19-21 Hatton Garden is confirmation, not exploration — you view the stone you selected, check the setting, and make any final adjustments.
Their diamond search includes both GIA certified natural diamonds and IGI certified lab-grown stones, searchable through the same interface with the same upfront pricing. They also offer matched diamond pairs for earrings — a category most Hatton Garden jewellers do not provide as a searchable inventory. It is worth noting that MOH London's diamonds are also listed on CaratHunter.com at premium market rates — a trade-facing diamond marketplace where dealers list certified stones. That positioning tells you something about the quality tier of inventory: this is not a discount operation.
Where MOH London is less strong is the tactile experience. You cannot walk in off the street, and you will not see a showroom full of display cases. If part of the joy of buying an engagement ring is the physical browsing — trying rings on, feeling the weight, being surprised by something you did not expect to like — MOH London's appointment model is less suited to that style of shopping.
MOH London strengths
- 1,000,000+ certified diamonds searchable online
- Full pricing transparency — no surprises
- GIA natural + IGI lab-grown — both certified
- Matched diamond pairs for earrings
- Premium inventory — also listed on CaratHunter.com
MOH London limitations
- Appointment only — no walk-ins
- No showroom browsing experience
- Less suited to impulse or discovery shoppers
- Requires comfort with online research tools
The real difference
It comes down to how you like to shop
This is not a question of which is "better." Both are well-regarded Hatton Garden jewellers with strong reputations. The difference is the experience — and what kind of buyer you are.
Choose Queensmith if you...
- Want to walk in without an appointment and browse
- Value trying rings on and comparing metals in person
- Want to watch your ring being crafted in the workshop
- Prefer a guided experience over independent research
- Are shopping as a couple and want the in-store moment
Choose MOH London if you...
- Want to compare thousands of certified diamonds by spec
- Value seeing exact prices before any conversation
- Prefer to do 80% of the research online, then confirm in person
- Want the widest possible diamond selection (natural and lab-grown)
- Are data-driven — you want to know the 4Cs and price per carat
Our take
What we actually think
Both are excellent choices — but for different reasons.
If this is your first time buying an engagement ring and you want someone to hold your hand through the process, Queensmith's showroom experience is hard to beat. The staff are patient, the atmosphere is welcoming, and the on-site workshop adds a layer of meaning to the purchase that online tools cannot replicate. You leave feeling like the ring was made for you — because it was, right in front of you.
If you are the type of person who reads every review, compares every spec, and wants to arrive knowing exactly what you are paying for, MOH London gives you tools that no traditional showroom can match. The ring builder with 1,000,000+ searchable diamonds and transparent pricing is genuinely unique on Hatton Garden.
Our honest advice: visit both if you can. Queensmith for the experience, MOH London for the data. You will quickly know which approach feels right for you.

Common Questions
Is Queensmith more expensive than MOH London?+
Queensmith positions itself as premium, with pricing reflecting their showroom experience and on-site workshop. MOH London operates as mid-range with transparent online pricing. For an equivalent 1ct solitaire engagement ring, you may find MOH London slightly lower due to their online-first overhead model — but the gap depends on the specific diamond and setting. Both offer competitive pricing for Hatton Garden. The best approach is to configure the same specs on both and compare directly.
Can I walk into both without an appointment?+
Queensmith welcomes walk-ins during opening hours (Monday to Saturday) — you can browse their showroom without booking. MOH London operates by appointment only. If spontaneous shopping matters to you, Queensmith has the advantage. If you prefer a dedicated, focused consultation with no waiting, MOH London's appointment model ensures that.
Do both sell lab-grown diamonds?+
Yes. Both Queensmith and MOH London offer lab-grown diamonds alongside natural stones. MOH London's ring builder lets you filter and compare lab-grown diamonds from a database of over 1,000,000 certified stones with prices shown upfront. Queensmith carries lab-grown options in their showroom, though the in-store selection will be smaller than what an online-first model can source on demand.
Which has better reviews?+
Both are well-reviewed. Queensmith holds a 4.9 rating on Trustpilot — one of the highest on Hatton Garden. MOH London holds a 4.8 on Trustpilot. The difference is marginal. What varies is the type of feedback: Queensmith reviews praise the in-person experience and warmth of staff. MOH London reviews praise the transparency of pricing and the ability to research independently before visiting.
Can both make a fully bespoke ring?+
Yes. Queensmith designs bespoke rings in-house using CAD and manufactures in their own on-site workshop — you can watch the process. Turnaround is typically 4-6 weeks. MOH London also offers a bespoke service, with designs configured through their online tools and manufactured by their London workshop. The experience differs: Queensmith is hands-on and in-person, MOH London is tech-assisted with in-person confirmation.
Which is closer to Farringdon station?+
MOH London at 19-21 Hatton Garden is approximately a 2-minute walk from Farringdon station. Queensmith at 98 Hatton Garden is closer to Chancery Lane station (about 3 minutes). Both are easily accessible — Hatton Garden runs between the two stations.
