Gold Jewellery Explained: Understanding Carat, Colour and Quality

Gold jewellery has been worn and treasured for centuries, yet many people are unsure what the different markings and colours actually mean. Understanding gold carat, colour and quality helps you make informed decisions when buying, repairing or valuing jewellery.

At Walter Bull & Son, we have worked with gold jewellery in Cirencester since 1815, offering expert advice rooted in traditional craftsmanship.

What Does Gold Carat Mean?

Gold carat refers to the purity of the gold used in jewellery. Pure gold is 24 carat, but because it is naturally soft, it is rarely used on its own for jewellery.

Lower carat gold is created by mixing pure gold with other metals to increase strength and durability. Common carats include 9ct, 14ct and 18ct gold. Each offers a balance between purity, colour and wearability, making them suitable for different types of jewellery.

The Difference Between Yellow, White and Rose Gold

The colour of gold jewellery is determined by the metals mixed with pure gold.

Yellow gold retains its classic warm tone through a blend of gold, silver and copper. White gold is mixed with palladium or similar metals and is often finished with a rhodium coating for brightness. Rose gold gains its soft pink hue from a higher copper content.

All three colours are equally durable when made to the same carat, and the choice is largely personal.

How Gold Quality Affects Wear

Higher carat gold contains more pure gold, giving it a richer colour but slightly softer structure. Lower carat gold is harder and often better suited to everyday jewellery such as rings and bracelets.

Choosing the right carat ensures your jewellery performs well over time, especially for pieces worn daily.

Understanding Hallmarks

Hallmarks are official markings that confirm the metal content of gold jewellery. In the UK, hallmarks also identify where the item was tested and the year it was hallmarked.

Reading hallmarks correctly helps confirm authenticity and quality, particularly when buying antique or vintage jewellery.

Gold Jewellery Repairs and Resizing

One of the advantages of gold jewellery is its ability to be repaired and resized. Gold can be worked, reshaped and polished by skilled goldsmiths without compromising the integrity of the piece.

At Walter Bull & Son, our in-house workshop carries out gold jewellery repairs, resizing and restoration, ensuring each piece retains its character and quality.

Valuing Gold Jewellery

The value of gold jewellery depends on several factors, including carat, weight, craftsmanship and design. Antique or bespoke pieces may carry additional value beyond the metal itself.

A professional valuation ensures gold jewellery is accurately documented for insurance, probate or personal records.

Final Thoughts

Understanding gold carat, colour and quality allows you to choose jewellery with confidence. Whether you are buying, repairing or valuing a piece, knowledge helps ensure your jewellery remains both beautiful and practical for years to come.
