A ring should feel comfortable every time you wear it. It should slide on easily, sit securely, and come off without a struggle. But over time, fingers change. Weight gain or loss, pregnancy, arthritis, or even just natural ageing can make rings feel too tight or too loose. Family heirlooms passed down through generations may also need adjusting to fit a new owner.
When this happens, resizing is the answer. But here’s the important bit: it has to be done properly. A badly resized ring can look uneven, feel weak, or even crack later down the line. That’s why it’s vital to choose an experienced jeweller who knows exactly how to handle the metal, the stones, and the setting.
At Blackwell Jewellers in Bexleyheath, our repair service The Jewellery Mechanic has helped thousands of customers with safe, seamless resizing. Whether it’s a plain gold band or a diamond engagement ring, we use professional tools and decades of experience to ensure your ring comes back fitting perfectly — without any visible sign of work.
In this blog, we’ll explain why rings need resizing, how the process works, what types of rings can (and can’t) be resized, and why trusting a professional is so important.

Why Rings Need Resizing
There are lots of reasons why a once-perfect ring may no longer fit the way it used to. The most common one is simple: our fingers change over time. Weight gain or loss, pregnancy, ageing, or arthritis can all affect the size of your knuckles and joints. Even the seasons can play a part, with fingers swelling in summer and shrinking in winter.
Another reason is inheritance. Family rings, such as engagement or wedding bands, are often passed down through generations. These sentimental pieces rarely fit perfectly straight away, and resizing is the best way to make them wearable again without losing their original charm.
Wearing a ring that doesn’t fit can cause problems. A tight ring may cut off circulation or even get stuck, sometimes needing to be cut off in an emergency. A loose ring, on the other hand, carries the constant risk of slipping off unnoticed and being lost forever.
That’s why resizing isn’t just about comfort — it’s about protecting both your jewellery and your fingers.

How Resizing Works
Resizing a ring might sound simple, but it’s a delicate process that requires skill, precision, and the right tools. At its core, resizing is about adjusting the band so it fits your finger perfectly again — without leaving any sign that the ring has ever been altered.
Making a Ring Larger
To increase a ring size, a jeweller usually makes a small cut in the band and inserts a piece of matching metal. That piece is then carefully soldered into place, shaped to match the rest of the band, and polished until the join is invisible. For slight adjustments, some rings can also be stretched, but this method is only suitable for plain bands without stones or engravings.
Making a Ring Smaller
To reduce a ring size, a small section of the band is cut out and the ends are soldered back together. The ring is then rounded, smoothed, and polished until it looks brand new.
The Finishing Touches
After the resizing, the ring is cleaned, polished, and, if it’s white gold, re-plated with rhodium to restore its shine. Stone-set rings are checked to make sure settings are still secure, since resizing can sometimes affect how claws sit around gemstones.
The goal is always the same: to return your ring looking exactly as it did before, just in the correct size. Done properly, you should never be able to tell it was resized.

Types of Rings That Can & Can’t Be Resized
Not every ring is the same, and when it comes to resizing, some are easier to adjust than others. Knowing which rings can be safely resized — and which can’t — will save you time, money, and disappointment.
Rings That Can Be Resized
-
Plain Gold or Platinum Bands – These are the simplest to resize. Adding or removing metal is straightforward, and the finished result is seamless.
-
Diamond or Gemstone Rings – Most stone-set rings can be resized, but they require extra care. Heat from soldering can affect settings or gemstones, so experienced jewellers take steps to protect them during the process.
-
Engraved or Patterned Rings – These can be resized, but the engraving or pattern may need to be re-applied to maintain the original look.
Rings That Are Difficult or Impossible to Resize
-
Tungsten, Titanium, or Stainless Steel Rings – These metals are too hard to cut and solder, meaning they can’t be resized in the traditional way.
-
Full Eternity Rings – Rings set with stones all the way around the band are extremely difficult to resize, as there’s no plain metal to work with.
-
Non-Metal Rings – Materials like ceramic or silicone can’t be resized.
If your ring falls into the “tricky” category, don’t worry. An experienced jeweller can often suggest alternatives, such as sizing beads or a new custom setting.

Why Professional Resizing Matters
When a ring doesn’t fit, it can be tempting to try quick fixes at home. Online, you’ll find all sorts of DIY “hacks” — stretching tools, boiling water tricks, or cheap ring adjusters. While they might seem like a shortcut, the truth is these methods often do more harm than good.
For example, stretching a ring too much can weaken the metal and distort its shape. Cutting corners with heat or chemicals risks damaging gemstones, especially softer stones like emeralds or opals. Even temporary adjusters can bend bands out of shape or cause skin irritation.
That’s why professional resizing is so important. An experienced jeweller uses the right tools, high-quality solder, and decades of skill to ensure the job is done properly. The band will be cut and reshaped seamlessly, the polish will match perfectly, and the structure will remain strong. When done well, you’ll never be able to see where the work was carried out.
More importantly, resizing by a professional keeps your jewellery safe. Sentimental rings — like engagement and wedding bands — carry memories that can’t be replaced. Trusting them to an expert is the only way to make sure they’re preserved for years to come.

The Right Fit, the Right Way
Your ring is more than just jewellery — it’s a symbol of love, family, and memories. Whether it’s your engagement ring, a wedding band, or a treasured heirloom, it deserves to fit perfectly. A ring that’s too tight isn’t just uncomfortable, it can damage the band or even injure your finger. A ring that’s too loose carries the constant risk of slipping off and being lost forever.
The good news is, resizing is a safe, affordable, and straightforward process when handled by an expert. From plain gold bands to intricate diamond rings, a professional jeweller can adjust the size while keeping the piece strong, secure, and looking as good as new.
