Black Friday is coming, and lots of people are thinking about buying diamond jewellery.
Maybe it’s an engagement ring they’ve been saving for.

Perhaps it’s a special birthday gift for someone they love. Or maybe they just want to treat themselves to something beautiful.
But this is the problem: Black Friday can be hard to understand. There are sales all over the place, prices are all over the place, and everyone says their deal is the best. You can get excited and buy something without really thinking it through.
The experts at Hatton Garden – London’s famous jewellery quarter – see this happen every year. They’ve put together some honest, practical advice to help shoppers make smart choices this Black Friday, whether they’re buying online or visiting a shop in person.
Start Now, Not on Black Friday Looking
One of the worst things shoppers can do is wake up on Black Friday and start looking for deals. By then, they’re stressed, rushing, and likely to grab whatever looks cheapest.
Start shopping smart now. They spend time thinking about what they really want. Is it a ring with a diamond on it? A necklace? Do you have earrings? What kind of metal do they like best: white gold, yellow gold, or platinum? What size feels right?
Before they go shopping, they also learn a little bit about diamonds. Even understanding the basics – like how the cut affects sparkle, or that colour and clarity impact price – makes a huge difference. A person who knows what they’re looking at can tell the difference between a real deal and a fake one.
And they made a plan for how much money they could spend. Not a “flexible” budget that keeps growing. A real budget they can stick to, even when they see something tempting. Big Discounts Don’t Always Mean Good Value
Walking past a shop window with “50% OFF!” in huge letters gets anyone excited. But jewellers in Hatton Garden will tell you – not all discounts are what they seem.
People who are smart about shopping compare prices. They look at several different jewellers to see what similar pieces actually cost. They look over the details very carefully because sometimes “sale” items are older stock or lower-quality items that didn’t sell well.
And they always ask about certification. Good jewellers give you certificates from independent labs that prove what the diamond really is. If there’s no certificate and the price seems unbelievably low, something’s probably wrong.
Lab-Grown Diamonds Are Changing the Game
Here’s something many people don’t realize: lab-grown diamonds are becoming hugely popular, especially for Black Friday jewellery deals.
These diamonds are real. They are real diamonds, but they were made in a lab instead of being dug up. Without special tools, scientists can’t tell the difference. But lab-grown diamonds typically cost 40-60% less than mined ones.
Think about that for a second. Already less expensive, and then you get a discount on Black Friday? That’s a lot of value.
For the same money, someone could get a much bigger diamond. Or they could get the same size and save hundreds – maybe even thousands – of pounds.
Plus, there’s no mining involved. No damage to the environment and no need to worry about where the diamond came from. It’s a choice that feels good as well as looking beautiful.
Going to Hatton Garden Makes a Big Difference
Anyone can shop online from their couch in their pyjamas. But people who live in or near London should really think about going to Hatton Garden before they buy something big.
Why? Because seeing diamonds in person is very different from seeing them in pictures. The way they catch the light, how they sparkle when they move – pictures just can’t capture it properly.
The jewellers there also know a lot about what they do. They can explain things in plain English, help someone find the best value for their budget, and answer questions honestly. They’re not trying to rush anyone or push them into buying something wrong.
Having a jeweller you trust is important for people who buy expensive jewellery or engagement rings. Someone who’ll clean the ring for free, check the stones are secure, help with resizing down the line.
Many Hatton Garden jewellery deals are also good in-store, and the personal service is often worth more than just clicking “buy now” online.
More people should care about returns and resizing.
A lot of people shop on Black Friday to buy gifts. And gifts sometimes need to be returned or, in the case of rings, resized.
Before they buy anything, shoppers should check how long they have to return or exchange it.
- Will it cost extra to return things?
- What if a ring needs to be made bigger?
- Are there different rules for things that are on sale on Black Friday?
Some shops make it difficult to return sale items. Others charge fees. It’s better to know this ahead of time than to find out later when you try to return something.
Black Friday Deals Usually Last Longer Than One Day
Despite the name, most jewellers run their Black Friday sales for several days. Many continue through the weekend, some even into the next week.
This is actually good news. It means people don’t have to rush. They can take their time, sleep on big decisions, ask all their questions, and really make sure they’re choosing the right piece.
If a jeweller is pushing someone to “buy right now before the deal ends,” that’s worth being suspicious about. Good jewellers want customers who are calm and happy, not stressed and in a hurry.
- Watch Out for Hidden Extras
- When you add everything up, that £500 ring on the website might end up costing more:
- Shipping costs (and insurance for valuable items)
- Sizing rings if needed
- Gift boxes or special packaging
- Longer warranties
Some jewellers include everything in the price they show. Others add costs at the checkout. It’s always worth asking for the complete, final price before deciding to buy.
Aftercare Is Part of the Cost
When someone buys diamond jewellery, they’re not just buying something for now – they’re buying something that could last a lifetime. That means aftercare is important.
Good jewellers offer things like:
- Free cleaning and checking (you should check your diamonds often to make sure they’re safe)
- Warranties if anything goes wrong
- Repair and resizing services
If there’s no help after the sale, the best Black Friday deal might not be the one that costs the least. Spending slightly more with a jeweller who’ll look after the piece properly often makes more sense.
Classic Styles Beat Trendy Pieces Every Time
Black Friday can get people to buy stylish things at low prices. But trends change. What looks cool now might feel dated in a couple of years.
Classic styles – simple diamond studs, elegant pendant necklaces, traditional engagement rings – never go out of fashion. People wear them more often because they go with everything. And if someone decides to sell later, classic pieces hold their value better.
When choosing between trendy and timeless, timeless usually wins. Especially for gifts for other people or expensive things.
Black Friday is best for big buys.
Here’s a tip from someone who knows: Black Friday jewellery sales often give the best value on higher-priced items.
Think about it. A 20% discount on a £200 item saves £40. The same 20% on a £2,000 item saves £400. That’s a lot more money saved.
Black Friday might be the best time for someone to buy something big, like an engagement ring, a special anniversary gift, or an investment piece. The savings are bigger, and the timing is good for Christmas and New Year’s proposals.
Believe that gut feeling
Shopping for diamond jewellery should be fun, not stressful. If something doesn’t feel right – whether it’s the deal itself, the jeweller’s attitude, or just a nagging doubt about the piece – it’s okay to walk away.
There will be other sales, other deals, other opportunities. The right piece at the right price will come along. Nobody should feel pressured into spending hundreds or thousands of pounds on something they’re not completely sure about.
