The Eco Silver After Hailstorm Necklace by Sirokoru. This unique handcrafted eco silver after hailstorm necklace is a delicate piece of designer jewellery with a soft pearly finish. It is made of the designers own Eco Act silver alloy which has a very high silver content - 964 per mille. However, note that the highest official stamp is 925. It means that the silver has at least a 925 per mille silver content. Sirokoru uses an additional flower-shaped stamp for Eco Act silver. Eco Act silver is produced without any harmful chemicals and there are no emissions. The silver stays brighter longer without tarnishing due to its high silver content. SIrokoru has developed this unique silver alloy themselves after years of metallurgic research and testing.
