We're committed to the highest level of quality, and only work with premium metals - recycled sterling silver and 9ct gold. Every piece of NJO Designs jewellery is hallmarked by the Assay Office at Dublin castle. The Assay office hallmark guarantees the precious metal content of every piece.
Our 9ct solid gold pieces are made to last forever. 9ct gold is made of 37.5% gold mixed with an alloy of other metals. 9ct gold will not oxidize, so you can wear your jewellery every day, every way. All our 9ct gold pieces are hallmarked with '375'.
Sterling Silver is an alloy made of 92.5% pure Silver and 7.5% Copper. We plate our silver jewellery in rhodium, which gives it extra shine and durability. Rhodium is one of the costliest metals due to it's rarity. All our sterling silver pieces are hallmarked with '925'.
18CT GOLD STERLING SILVER
Our 18ct gold sterling silver collection is crafted in sterling silver and coated in a thick layer of 18ct gold to give it its shiny gold colour. All our 18ct gold sterling silver pieces are hallmared with '925'.
