What follows is a brief introduction to the precious metals used in our workshop in order to help you choose a metal that best suits your piece of bespoke jewellery.

We supply 100% recycled palladium, platinum, silver & 14ct and 18ct yellow, rose and white gold.We source our metals from  Earth-minded refining and manufacturing companies who pride themselves in being socially and environmentally responsible.  They refine metal from the large existing supply of gold, silver and platinum that has already been mined, meaning there is no more damage done to the Earth or people to produce your jewellery. Once these metals are refined back to their pure form they are physically no different to newly mined metals so they are independently audited and certified as 100% recycled. Please see our ethics page for more information.  

Yellow gold - 18ct yellow gold has a brighter, deeper yellow hue than 14ct simply due to the higher pure gold content. The Assay mark for gold reflects it's purity, with 18ct at 750 parts per thousand, 14ct at 585 parts per thousand and 9ct at 375 parts per thousand. These numbers, 750, 585, and 375 are stamped or applied by laser to the item of jewellery as part of the Assay (or Hallmark) process. The other elements present in the gold alloys that we use are silver, zinc and copper. The choice of which purity of precious metal comes down to personal preference with regards to the colour and feel of the gold or, of course, to the cost aspect of the piece to be made.

White gold - the 'whiteness' of this gold alloy is due to the proportions of copper and silver and also the addition of platinum and/or palladium which are both very white metals. We work in both 14ct and 18ct white gold with the 18ct giving a brighter white colour due to a high palladium content in the alloy.

Rose or 'red' gold - the red tinge in this beautiful metal is due to the proportion of copper used in the alloy. There is also a difference in hue between the two purities of rose gold that we work with.

Platinum - the rarest of the 'platinum metals' and highly prized for its colour and intrinsic value. These metals have a very white colour to them and are very hard wearing with a bright lustre. They do not react with the oxygen in the air like silver does and so do not tarnish easily. A platinum wedding or commitment ring has a shine that lasts as it is so durable and has an inimitable silvery grey/white almost blue colour. The platinum alloy we use is hallmarked at 950 parts per thousand and also contains copper.

Palladium - one of the platinum group of metals. Palladium is a metal used more and more for its similar properties to platinum but which is considerably more affordable. This metal has a recently introduced British Hallmark with three options on purity - 500, 950 & 999 parts per thousand with the other elements being copper and gallium (a silvery white metal with a low melting point). 

Rhodium - this is another of the platinum group of metals and used as a plating finish to some silver jewellery and white gold pieces. This finish adds an extra bright shine and white tint to a piece of jewellery, though if a piece is finished correctly this is unnecessary. We are happy to rhodium plate your bespoke piece of jewellery for you on request though it is a finish that does wear off and can cause problems with regards to polishing and keeping clean.
