about us

We are a family owned business that started in Gothenburg, Sweden in 1968, since then we have been in Perth Australia and now, Sydney Australia. We have always strived to give our customers the best possible quality at the most reasonable prices, and have been doing so continuously since the first store was opened by Arto Agopyan at the age of 20. Arto learnt his trade from the traditional Armenian goldsmiths in Istanbul, Turkey, as a young boy, and then emigrated to Sweden as a young man, keen to create his own business he started "Arto's Jewellery" in Sweden and his pieces are still found at auction in Sweden today, with his hallmark stamped on them. Today the business has been renamed, but the lineage remains the same.
