Where does a person go in London to buy an engagement ring without walking into a high-street chain and paying chain prices? Hatton Garden is the obvious answer, and The Diamond Ring Company sits right in the middle of it, at Suite 124, 100 Hatton Garden. The site is built around engagement rings first, and the range of those is genuinely deep: classic solitaires, shoulder-set designs, trilogy settings, halos, and bezel-set styles, plus lab-grown variants for buyers who want the look at a different price point. Diamond cuts run through round, oval, emerald, pear, radiant, cushion, and princess, so a buyer arrives with a shape in mind and finds it covered. That alone tells you The Diamond Ring Company is set up for people who already know roughly what they want and just need the right stone in front of them.

That breadth is the first thing worth saying about The Diamond Ring Company, because plenty of jewellers lead with a handful of hero pieces and leave you guessing about the rest. Here the catalogue is laid out properly. Wedding rings come in classic and diamond-set forms. Eternity rings split into claw and channel settings, which is a distinction that becomes meaningful once you start comparing how the stones sit and how the band wears over years. There are diamond stud and drop earrings, diamond pendants, and tennis bracelets. Men are not an afterthought either, with diamond and patterned wedding bands listed as their own line. The Diamond Ring Company has clearly thought past the engagement-ring buyer to the anniversary, the wedding party, and the gift shopper.

For anyone who does not want a colourless diamond, there is a coloured-gemstone range covering ruby, sapphire, emerald, and yellow diamond rings. Lab-grown diamonds are stocked from 1.5 carat up to 4 carat, which is a serious size band and shows The Diamond Ring Company is taking the lab-grown side seriously instead of treating it as a token gesture. The bespoke and custom design service runs alongside the standard inventory, so a customer can either buy something off the existing range or have a piece made to order. Both routes are presented as normal, not as some premium upsell hidden behind a quote request. A jeweller that puts made-to-order work on the same footing as its shelf stock is usually one that has the workshop relationships to deliver it, and that is the impression here.

The service list goes past the point of sale, and that tends to separate a real jeweller from a storefront. The Diamond Ring Company offers ring resizing, rhodium plating, and polishing, all of which are the things you genuinely need months or years after the purchase when a ring loosens, dulls, or picks up scratches. Free in-person viewings by appointment are part of the offer too, which fits the Hatton Garden model where buyers expect to see and handle a stone before handing over thousands for it. A buyer can book a slot, turn up, and look at the real thing under proper light.

Price is handled with a bit more honesty than the diamond trade usually manages. Budget options under one thousand pounds are highlighted directly, which is unusual for a diamond seller, since the trade often prefers to bury the entry-level pieces and steer everyone toward the larger stones. Calling out the sub-thousand-pound range up front puts The Diamond Ring Company in reach for the first-time buyer and the tighter budget as much as the big spender, which is a stance not every Hatton Garden name bothers to take. Pair that with the lab-grown stock and the message is fairly clear: there is a way in at most price levels.

There is also a diamond education section on the site, and this is the part that says the most about intent. A company that walks a customer through cut, clarity, colour, and the rest is, on the whole, a company that expects an informed buyer to come back instead of chasing a one-time impulse sale. It does not guarantee the advice is faultless, but a teaching section sitting next to the product pages shows The Diamond Ring Company is comfortable with customers who ask questions before they buy. For a purchase this size, a slick photo gallery cannot substitute for that.

Getting in touch and checking the reputation

On the question of whether a stranger can reach the company, the answer is easy. The phone number sits on the homepage, the full Hatton Garden address is displayed prominently, and a contact and appointment page handles bookings. Office hours are spelled out: Monday to Friday from half past eight in the morning to half past six in the evening, and Saturday from ten until four. That Saturday window is the practical detail, because most ring shopping happens at the weekend and a seller closed on Saturdays effectively shuts out a large slice of buyers. Reaching The Diamond Ring Company takes no detective work.

Reputation is where the picture gets strong. The Diamond Ring Company carries 1,804 reviews on Trustpilot at a five-star rating, which is a substantial volume and well beyond what a circle of friends and family could quietly inflate. Its Instagram account, @the_diamond_ring_company, references over a thousand five-star reviews, a figure that lines up roughly with the Trustpilot total instead of contradicting it. Volume at that level, held at a top rating across nearly two thousand separate customers, is difficult to manufacture. It is the kind of track record a cautious buyer wants to see before handing over money for something they will wear for life.

A word of caution on searching, though, and it is the company's good fortune that it does not bite them. Several US businesses share a similar name, and the Yelp and Better Business Bureau entries that surface in a general search belong to those unrelated American firms, not to The Diamond Ring Company in London. A shopper who lands on a poor US listing and assumes it is the same outfit would be judging the wrong company entirely. The relevant verdict for the UK business is the Trustpilot record, and that one is excellent.

So what is the honest read on The Diamond Ring Company? It is a well-stocked Hatton Garden jeweller that covers the full spread of engagement, wedding, and eternity rings, runs a real coloured-stone and lab-grown range, takes on bespoke work, and backs all of it with aftercare like resizing and replating. Contact is open and the hours are sensible. The review record is large and consistently high. The one genuine wrinkle is the name confusion in search results, which is on the searcher to navigate and not a fault in the business itself. The sub-thousand-pound flag keeps The Diamond Ring Company in reach even on a modest budget, and the lab-grown range extends that further still. Taken together, the published evidence holds up: a full product range, real aftercare, plain hours, an address you can walk to, and 1,804 five-star reviews behind it. On what the site puts in writing, The Diamond Ring Company gives a careful buyer plenty to act on.
