Fine Silver

Fine silver is pure silver it have no alloys, this is very soft and not generally used for making jewellery

Sterling Silver

Sterling Silver is fine silver alloyed with copper, this makes it harder and suitable for jewellery manufacturing. The mix is 925 parts fine silver 75 parts copper.

Fine Gold

Fine gold is pure gold (24 carat) this is very soft and not generally used for making jewellery

18ct Gold

18ct gold is fine gold alloyed with silver and copper (with some trace elements) It has a bright yellow appearance. The mix is 750 parts fine gold 200 parts fine silver and the balance copper and trace elements. The silver and copper mix can be changed to give pink, rose and red gold colours.

14ct Gold

14ct Gold, this is general used in the USA but you are starting to see more of it in NZ . The mix is 525 parts fine gold the balance fine silver and the balance copper and trace elements. The silver and copper mix can be changed to give pink, rose and red gold colours.

9ct Gold

9ct Gold is fine gold alloyed with silver and copper (with some trace elements) but has a duller look to it. Its percentage of gold is much less, 375 parts fine gold 625 parts silver and copper (with some trace elements). As you can see 9ct gold has only 37.5% gold (less the half)

White Gold

White gold’s are alloyed the same as the yellow but different metals added to give it the white colour. There are many different types of white gold. They are alloyed with differing percentages of Platinum, palladium, nickel. Depending on the mix used will depend on the brightness of the white gold. Also some white gold is Rhodium plated after polishing. What is Rhodium plating. Rhodium plating is a process that adds a thin plate of rhodium over top of white gold to make it a brighter white. This has become a very common practice in mass produced Jewellery. At JewelCraft we use high grade white gold and generally don’t have to plate them.

Platinum

Platinum is a white metal, but unlike gold it is used in jewellery in almost its pure form (approximately 95% pure). Platinum is extremely long wearing and is very white, so it does not need to be rhodium plated like white gold does. Platinum is very dense and heavy metal, so a platinum ring will feel heavier than an 18ct gold ring.
