Gold is one of the first metals that people have come to know and is found in nature mainly as nuggets. Due to its properties and appearance, gold is an excellent material for use in jewelry - it is a shiny, soft and highly stretchable metal. Pure gold is too soft to be used in jewelry, so it is alloyed with other metals to achieve the desired machining properties, hardness and color tone. Yellow gold is obtained by adding silver and copper to the gold. Increasing the amount of copper gives red gold. White gold is obtained when palladium is added to gold. Zinc is used sparingly in all alloys to improve casting and machining properties. In Finland, the gold content of a gold alloy is stamped in parts per thousand, but is often stated in colloquial language in carats. Promillets indicate the amount of precious metal that must be present in the product. One carat, in turn, means 1/24 part. The most typical gold alloys used in jewelry are 14 carat or 585 ppm and 18 carat or 750 ppm alloys.
Festive diamond jewelry uses the so-called European yellow gold, which is brighter yellow in color than the reddish Finnish alloy commonly used in Finland. It is also possible to get diamond jewelery made of a reddish alloy from the order, but by default when ordering from the online store, there is a more yellow alloy.
White gold contains just as much yellow fine gold as other yellow and red gold alloys of the same color. White gold of light color is obtained from palladium metal alloyed with it. Palladium is heavier and more expensive than other alloys. For this reason, white gold products are slightly more expensive than yellow and red gold products.
White gold is surface treated with rhodium, a platinum group metal. This is called rhodinization. Rhodinization produces a pure white surface in white gold, while white gold itself is grayer in color. The rhodinizing coating wears off over time and may need to be replaced as the ring begins to turn scratched and greyish in color.
Red or rose gold is obtained by adding copper to the gold alloy to bring a shade of red. Red gold has really made its way through the market in recent years and is currently very trendy.
Almost 100% recycled gold
The gold alloy we use is entirely certified recycled gold supplied by K.A Rasmussen. K.A. Rasmussen guarantees more than 99% recycling for the mixture, but in practice under normal conditions the recycling rate is 100%. We also strive to buy as much scrap gold as possible from our customers for recycling. Thanks to recycling, the story of Grandma’s old sturdy engagement ring can continue in up to five new slimmer rings.
