77 Diamonds is not an ad network. It is a diamond jewellery brand, and this article looks at it as an advertiser: how it presents itself, who it targets, and what other businesses can learn from its marketing. I worked only from public information such as its website, press coverage, and reviews. I have no access to its ad spend or campaign data, so the marketing analysis is my interpretation.
Introduction
Buying a diamond is one of the most emotional and expensive purchases a person makes, and most buyers are nervous. They worry about being overcharged, buying the wrong stone, or paying for something they cannot inspect. Any jeweller that advertises online has to solve that trust problem before it can sell anything.
77 Diamonds is a useful case study because it started online at a time when that was unusual, then added physical showrooms and grew across Europe and the Middle East.
Who Is 77 Diamonds?
The company was founded in 2005 by Vadim Weinig, a third-generation diamond merchant, and Tobias Kormind, who came from a blue-chip investment background. Some profiles give 2004 as the start year, so sources differ slightly. The name comes from the first recorded diamond engagement ring proposal, which legend says was made in 1477. 77 DiamondsRoyist
The company describes itself as a home of custom handcrafted engagement rings and fine jewellery, with a promise of fair prices, honest guidance, and conflict-free sourcing. Customers can design a piece in a few steps, chat online or by phone, or book an appointment at a showroom. 77 Diamonds77 Diamonds
From Online Store to Showroom Network
The growth pattern matters for marketing. It launched when online jewellers were still new, and its Mayfair showroom opened in 2013. (One other source gives 2009 for the first showroom, so treat the exact year with caution.) Appointment-only showrooms then followed in cities including Manchester, Frankfurt, Berlin, Zurich, Stockholm, and Munich, with Dubai opening in April 2024. Its social media profile now describes 14 showrooms worldwide and a Basel showroom in Switzerland. Our Story – 77 Diamonds +2
The co-founder once explained the thinking behind this. He said the business is not cheaper to run than a traditional store, but that it is about being where customers are, rather than putting a shop on a high street and hoping for foot traffic. That is a marketing idea as much as a retail one: reach people online first, then bring the serious ones into a personal appointment. City A.M.
The Marketing Approach
1. Lead with trust
The brand’s messaging keeps returning to the same few promises: certified stones, ethical sourcing, fair pricing, and expert guidance. Its homepage stresses independently certified, conflict-free diamonds, a return window of under 30 days, and free resizing within 60 days. These are risk reducers. For a high-value product, removing fear often persuades more than praising the product. 77 Diamonds
2. Personal service as the main selling point
Reviews suggest the human advisor is central to the experience. One Danish customer praised a professional adviser who guided them confidently through the whole process. Another reviewer in the Frankfurt listing credited a named adviser for clear explanations and patient answers. For advertising, this means the real product being sold is reassurance, not just a ring. trustpilottrustpilot
3. Targeting emotional milestones
The company frames its business around engagement and the moments that follow. Engagement rings are a life-event purchase, so advertising can be timed and targeted around people likely to be planning to propose. One independent review described the brand as marketed mainly at millennials, offering affordable diamonds by sourcing directly from suppliers. 77 DiamondsDiamonds Pro
4. Design tools as a hook
The company has long promoted an online design platform, and says it still wins digital innovation awards. Letting a shopper design a ring is engaging: it keeps them on the site, builds a sense of ownership, and gives the brand a reason to follow up. 77 Diamonds
5. Social proof at scale
Its Trustpilot page shows thousands of reviews, with a very high score. Display of reviews is a form of advertising in itself. A prospective buyer who is nervous about a large purchase will check these ratings before enquiring. trustpilot
6. Playful social media voice
Its social presence mixes luxury with humour. One post joked about students stressing over exams while the poster worried about which yacht deck had the best view for their diamonds. That shows a brand trying to feel modern and personality-driven, rather than stiff and traditional. X
7. Local showroom marketing
Each new showroom is announced with location details and an invitation to visit. Opening in cities like Dubai, Basel, and Frankfurt lets the brand run local campaigns in local languages, which reviews on regional Trustpilot pages suggest it does. X
Strengths
Clear positioning. Custom, ethical, fairly priced diamonds with personal guidance is easy to understand and easy to advertise.
Trust signals everywhere. Certification, return policy, awards, and reviews all support the same message. Its listed recognitions include digital innovator awards in 2019 and 2021, and a website of the year award in 2017. Wikitia
Online reach with offline conversion. Ads and search bring people in, and showrooms close the sale. This suits high-value purchases better than pure e-commerce.
Product range that supports different budgets. It offers natural diamonds, gemstones, and laboratory-grown diamonds, including a signature cut in lab-grown stones. Lab-grown options widen the audience for advertising. 77 Diamonds
Strong customer stories. Engagement purchases produce emotional testimonials, which make natural user-generated marketing.
Weaknesses and Risks
Delivery experience can undo good marketing. A Danish reviewer complained that FedEx delivery gave little notice, no way to change timing, and left the parcel at the door. Another customer praised the advisor but reported the wrong ring size and a scratched ring on delivery. A brand that sells trust cannot afford these slips. trustpilot
Independent critics question value. One diamond review site said it found comparable or better stones about 10 percent cheaper at large online rivals, and criticised some certificate types. This is one opinion, but it shows the brand’s pricing claims face scrutiny. Diamonds Pro
Review management questions. The same Danish reviewer said the company had tried repeatedly to remove their review. That is a single customer’s allegation, but reputation is sensitive in this category, and any perception of hiding criticism can hurt.
Competition. Large online jewellers compete hard on price and inventory, so a boutique brand must keep justifying its premium.
Heavy reliance on advisors. A personal-service model depends on consistent staff quality across many showrooms, which becomes harder as the company expands.
Lessons for Other Advertisers
- For expensive purchases, sell reassurance first. Certifications, return policies, and human advice reduce fear.
- Use a low-pressure first step. Design tools, chat, and appointments invite interest without demanding commitment.
- Pair digital reach with real-world contact. Ads start the conversation and a personal meeting finishes it.
- Target life events. Engagements, weddings, and anniversaries create predictable moments when people are ready to buy.
- Match ads to the local market. Language and cultural expectations differ between Germany, Switzerland, and the Gulf.
- Protect the experience after the sale. Delivery, sizing, and aftercare determine whether reviews help or hurt.
- Answer criticism openly. Public replies to unhappy customers, as the company has done on review pages, show accountability.
- Use humour carefully. A light tone attracts younger buyers, but luxury brands should keep it consistent with quality.
Sample Campaign Idea
Suppose a similar jeweller wants to reach couples planning to propose. It could run search ads for phrases like “custom engagement ring,” show social ads with real customer stories, and offer a free design consultation. Visitors who use the design tool could be retargeted with a reminder about the return policy and a link to book a showroom visit. After purchase, an email would confirm delivery details and explain resizing. Each step reduces fear, and the last step protects the reviews that feed the next round of advertising.
Conclusion
77 Diamonds shows how a brand can turn a nervous, high-cost purchase into a guided experience. Its strengths lie in trust messaging, personal service, and a mix of online reach and physical showrooms. Its weak points, mainly delivery problems and price scrutiny, are reminders that advertising promises must be backed by operations. For any business selling an expensive or emotional product, the lesson is that people rarely buy on price alone; they buy when they feel safe.
