Precious Metal





Pt 900 VS Pt 950

The notations ".900" and ".950" speak to the purity of platinum, but not to its quality; the percentage is too small to significantly affect the quality. 

A ".950" purity hallmark indicates that the pure platinum has been alloyed with 5% of another metal.

A ".900" purity hallmark indicates that the pure platinum has been alloyed with 10% of another metal. 


Rhodium is a silvery-white transition metal. It holds the distinction of being the world's most expensive precious metal. It has an atomic number of 45 and is about as nonreactive as gold. The only way to dissolve rhodium is with sulfuric acid. Part of rhodium's appeal comes from its high reflectance, almost unique among the metals. It is sometimes used as an expensive and flashy alternative to silver in jewellery, on which it is sometimes plated. Some of the most expensive consumer items in the world are made from rhodium.

Rhodium plating is a metal deposition process used to coat materials with a decorative and protective layer of rhodium. Rhodium is a noble metal that imparts an extremely bright and hard wearing finish when applied as plating.   When applied as a thin plate, it affords a durable finish of exceptional brightness.  Rhodium finishes can greatly enhance the appearance and longevity of any metal to which they are applied.





The colour of gold is determined by two factors:

  • The type of metal alloys included
  • The percentage of each metal alloy

One common question that is asked is, what is the difference between sterling silver and 925 silver. The short answer is, there is none. Sterling silver and 925 silver are different names for the same silver alloy.

Pure silver is much too soft to be used in jewellery, it is often combined with other metals to create a more durable metal. When 92.5% of pure silver is mixed with 7.5% of other metals (often copper, nickel or zinc) the resulting alloy is called sterling silver. To identify it as such, the number 925 is stamped upon the silver, often in a hidden part of the jewellery. This number is known as the hallmark and denotes the percentage of silver purity in the alloy. In other words, 925 is the same as sterling silver, meaning that if there is any other stamp on the metal, it is not sterling silver. Alternately, the hallmarks STER, STG, SS and Sterling Silver may be stamped in place of 925.
