Our Materials

Links of London Metals

Sterling Silver

Pure silver is too soft to use to manufacture jewellery, which is why we use sterling silver (an alloy of silver combined with copper and other base metals). Out of 1,000 parts, sterling silver consists of 925 parts silver and 75 parts other metals; hence the hallmark on our silver is 925.

Once exposed to the atmosphere, all silver is prone to some tarnishing. When this occurs we recommend cleaning with a non-abrasive polishing cloth to renew the original brilliance of the surface. Heavier discolouration should be removed using specialist polish or dip, except where there are materials present that would be damaged by the solution – such as opals and pearls.

Contact with perfumes, hairspray, chlorinated or salt water and household cleaning products will cause discolouration and should be avoided.

18 Kt Gold

We’re proud to use 18 kt gold in our jewellery. Out of 1,000 parts, 18 kt gold consists of 750 parts gold and 250 parts other alloys; hence the hallmark for our 18kt gold is 750.

Different alloys are used in 18 kt gold to allow specific characteristics to be achieved; most commonly colour variations such as rose or white. Due to the properties of the other alloys, gold can discolour. To keep your gold jewellery lustrous and shiny, we recommend cleaning it with a soft jewellery polishing cloth (available to buy in-store).

Contact with perfumes, hairspray, chlorinated or salt water and household cleaning products will cause discolouration and should be avoided.

18 Kt Gold Plated Vermeil Sterling Silver

Our beautiful gold vermeil jewellery is crafted from sterling silver and plated with a layer of 18 kt gold over 2.5 microns thick. As you wear your vermeil jewellery, the gold layer will wear slightly and its colour will gradually change over time.  To help preserve the original colour, if your jewellery gets wet dry it immediately and avoid it coming into contact with perfume, household cleaners and any other chemicals or abrasives. Polish your piece occasionally with a soft lint-free or microfibre cloth to maintain its shine, too.

Hallmarking precious metal has been used in Great Britain as a form of consumer protection since 1300AD. Before a hallmark can be applied, the metal must be 'assayed' (checked for purity) by one of the four UK Assay Offices. All precious metals must be hallmarked prior to sale. There are 3 compulsory marks:

  • The sponsor’s mark shows who sent the item for testing. For Links of London the hallmark is LL.
  • The standard mark shows the standard fineness of precious metal. For silver it is 925 and for gold it is 750.
  • The Assay Office mark shows which assay office has tested the item.  Each Assay office has their own symbol.

Links of London Diamonds and Precious stones

All Links of London diamonds and precious stones are hand-selected for purity and colour. Stone-set jewellery requires extra care and consideration during wearing.


What is a diamond?

Diamonds are the purest and hardest of the natural gemstones. A diamond is said to last an eternity, making it the ideal stone to symbolise the eternal bond of love. A diamond is made up of virtually pure carbon, which formed millions of years ago into a crystal, many miles below the earth’s surface.

What are ‘conflict diamonds’?

‘Conflict diamonds’ is the term used to describe diamonds, which are illegally traded to fund conflicts. To prevent the trade of conflict diamonds the UN, Governments, the diamond industry and NGOs (such as Amnesty International) agreed a process called the Kimberley Process.

What is the Kimberley Process?

The Kimberley Process requires participating governments to ensure that each shipment of rough diamonds are exported in a secure container, and accompanied by a uniquely numbered, government-validated certificate stating that the diamonds are conflict-free.

How do Links of London ensure their suppliers comply with the Kimberley Process?

All our suppliers are audited and have to sign the following agreement to confirm they are adhering to the Kimberley process and that they are not using unethical means to produce the goods:

It is a requirement that all Suppliers refrain from associating themselves with or directly conducting unethical practices and procedures including providing safe working conditions. The Company will only conduct business with Suppliers who have signed up to conducting all the necessary requirements to ensure the diamonds used in all products are bought in accordance with the KPCS guidelines sections 1-6. Documentary evidence will be required to provide proof of processes used during times of QC Audit to be conducted by the Company.

What are the four ‘C’s?

A perfect diamond is extremely rare; often diamonds have imperfections, although these are not visible to the human eye without magnification.

In order to help determine the quality of a diamond each stone is rated using the four ‘C’s. The four ‘C’s are: Carat, Cut, Colour and Clarity - which are all equally important in defining the quality of a diamond. 

Carat: Diamonds are sold by the carat, which refers to the weight of the diamond, rather than the size. Different carat weights are used in our jewellery depending on the design. 

Cut:  The cut of a diamond refers to the shape, proportion and finish of the final stone. 

Colour:  Diamonds can come in a variety of colours, depending on the elements present when they form. 

Clarity:  The clarity of a diamond refers to its purity and the inclusions in the diamond. The fewer the inclusions in the diamond the greater the clarity and more valuable it is.

Stainless Steel

Links of London use medical grade stainless steel, which is compliant with EU REACH regulations.

REACH Regulations

All Links of London products adhere to the EU REACH Regulations, which restricts the use of potentially hazardous materials in jewellery.  REACH Regulations control the use of nickel, cadmium and lead in all parts of jewellery.
