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.

Historical Significance & Symbolism

Aquamarine’s history is as rich and intriguing as its appearance. For centuries, sailors believed this gemstone held protective powers, considering it a talisman that would protect them against the dangers of the sea. Its name, derived from the Latin words “aqua marina” (meaning "sea water"), reflects its connection to the ocean and its calming influence. Beyond its nautical ties, aquamarine also symbolises peace, tranquillity, and emotional healing. It is believed to bring clarity of mind, relieve stress, and promote inner calm. This gemstone has long been cherished as a symbol of purity and balance, making it a meaningful choice for anyone seeking a sense of peace and harmony in their life.The Beauty Of Aquamarine

Reminiscent of rolling ocean waves, aquamarine is loved for its mesmerising shades of blue and ability to capture and reflect light. Whether set in gold, silver, or platinum, the precious stone’s vibrant hue stands out beautifully, creating a striking yet subtle presence that’s versatile enough to complement a range of styles and occasions. From statement rings and oversized earrings to dainty bracelets and delicate pendants, aquamarine adds an undeniable allure to any piece.Aquamarine For Jewellery

One of the many reasons to choose aquamarine for your next jewellery piece is its durability. With a rating of 7.5 to 8 on the Mohs hardness scale, aquamarine is a resilient gemstone that can withstand everyday wear. Whether set in a ring, bracelet, or pendant, it will maintain its appeal for years to come. The stone’s cool blue tones make it an incredibly versatile choice that complements various metal types. It also pairs well with diamonds and other gemstones to create a dynamic design.Caring For Your Aquamarine Jewellery

While aquamarine is a durable gemstone, like any precious stone, it requires proper care to keep it looking its best. To clean your aquamarine jewellery, simply use a cloth and warm, soapy water. Gently scrub the stone with a soft brush to remove any dirt, and avoid harsh chemicals or ultrasonic cleaners, as they may damage the stone over time. When storing your aquamarine pieces, keep them in a soft pouch or a separate compartment in your jewellery box to prevent damage.Shop Aquamarine Jewellery
