At Diamonds Factory all our products are hallmarked as per UK hallmarking law from London Assay Office (The GoldSmith Company)
The Goldsmiths' Company Assay Office is the oldest assay office in the United Kingdom. It has provided hallmarking services since The Goldsmiths' Company was founded in the 1300s. The company received its royal charter in 1327 and ranks 5th in order of precedence of the 12 Great Livery Companies of the City of London.
Hallmarking dates back to the 1300s when Edward I of England passed a law requiring any item made of silver, which was offered for sale, to be at least of equal quality as that of the coin of the realm (silver currency). The wardens of The Goldsmiths' Company were tasked with visiting workshops in the City of London to assay (test) silver articles. If these articles were found to be below standard they were originally destroyed and the metal forfeited to the King. If they passed, each article received the King's mark of authentication - the mark of a leopard's head. By 1478, there were several hundred workshops and merchants manufacturing silver articles in the City of London. It was not possible for the wardens to visit them all so the merchants were ordered to bring their items to Goldsmiths' Hall for testing and marking and a permanent Assay Office was established in the building. This is the origin of the term hallmark - struck with the King's mark at Goldsmiths' Hall.
In 1544 the Goldsmith's Company adopted the King's mark as their town mark and the mark of the leopard's head is now internationally recognised as the mark of this assay office.
The Goldsmiths's Company Assay Office is still based at Goldsmiths's Hall and remains the oldest company in Britain to be continually trading from the same site. However, it also has two satellite offices; at Greville Street in Hatton Garden in the heart of the London jewellery quarter and within a high security complex near London's Heathrow airport. It now has a new off-site facility within the Dalston-based jewellery manufacturer, Allied Gold. This is the first time in the Assay Office's 700 year history that it has opened permanent hallmarking services on a customer's premises.
In addition to hallmarking, the office has now expanded its range of services to support the jewellery trade and enforcement authorities. It offers a variety of specialist analytical services including nickel, lead & cadmium testing, antique silver dating, non-destructive compositional analysis, plating thickness measurement and a melt and assay service for scrap precious metal carried out in their fully independent on-site laboratory. Other services offered are a jewellery valuation service, laser marking, trading standards assistance, high quality photography and a comprehensive range of training and educational seminars, lectures and specialist events.
Paris Men's Fashion Week has long been a barometer for the future of menswear, but this season, it wasn't just the tailoring making a statement. Jewellery emerged as one of the defining elements of modern dressing, moving beyond the finishing touch to become an integral part of every look.

Relaxed silhouettes, refined accessories and effortless layering defined the mood on and off the runway. For Paris stylist Keyvan Nejad, the shift was impossible to ignore.
"Accessories have taken on a much more prominent role," he says. "Sunglasses, scarves, ties, belts and, of course, jewellery are no longer just finishing touches. They've become central elements of a look."
Dressing with intention
Rather than selecting jewellery to complete an outfit, Keyvan built each look around pieces that echoed the season's softer approach to tailoring.
"Tailoring has become more relaxed. Silhouettes remain elegant, but with softer, more effortless proportions," he explains. "I wanted my jewellery selection to reflect that same spirit by choosing pieces that feel like elevated everyday essentials."
That philosophy shaped every detail. Slim yellow gold bands were stacked across multiple fingers, while diamond-set rings introduced subtle brilliance without overpowering the look. A classic diamond tennis bracelet sat alongside a polished gold bangle, creating contrast through texture, while layered pear-shaped diamond pendants added depth with understated elegance.
Why mixed metals are having a moment
One of the most striking details of Keyvan's jewellery styling was his decision to pair yellow gold with rose gold.
"I couldn't decide between the yellow gold and the rose gold versions, so I ended up choosing one of each," he says. The result is a reminder that modern styling is less about following convention and more about creating balance.
"When it comes to jewellery, mixing yellow gold and rose gold is absolutely possible," he adds. "It's a styling tip worth keeping in mind." For Keyvan, rose gold also brings warmth to tan skin tones, offering another subtle way to personalise a jewellery collection.
Jewellery should feel personal
While trends offer inspiration, Keyvan believes personal style should always come first.
"I don't believe in strict jewellery rules. It's all about expressing your personality," he says.
Instead, he focuses on choosing pieces with purpose.
"Every piece should feel intentional. I prefer wearing a few carefully chosen pieces that complement each other rather than over-accessorising. For me, jewellery should enhance a look, not overpower it."
That same philosophy extends to versatility. Rather than building a collection around occasions, he prefers timeless pieces that adapt to different moments.
"I always adapt my jewellery to the occasion, not just the outfit," he explains. "I like investing in timeless pieces that can be worn in different ways, whether it's for a casual daytime look or a more formal evening event."
A defining moment for men's jewellery
If Paris Men's Fashion Week proved anything, it's that jewellery has become an essential part of contemporary menswear. Layering, mixed metals and refined diamond pieces offer new ways to express individuality while complementing modern tailoring.
As Keyvan's approach demonstrates, the most compelling jewellery isn't worn to follow trends. It's chosen with intention, worn with confidence and styled as naturally as the clothes themselves.
