Why has the ring made of white gold become yellow? Why has the necklace made of silver, darkened? Can you make a ring according to my idea? Is it possible to order a ring, which is of yellow gold in a store, in white gold? Why are sometimes two, what looks like, identical pieces of jewellery more expensive at Zlatarna Celje than somewhere else? In one of the collections of Zlatarna Celje I have seen some new colours of gold and silver, brown and black? Is this still real gold and silver? I have bought a silver necklace Lencia, which has been gilded. Is the paint going to wear off? I have noticed that Zlatarna Celje has a collection produced by electroforming. What does this stand for? I have noticed that sometimes you use the term diamond, and at other times brilliant. Is there a difference between the two? In one of your stores I have noticed that you also offer jewellery with emeralds. How is it possible that emeralds are of different colours, some have veins, some are quite cloudy and still they are all so expensive? I am interested in a necklace made of white gold and brilliants. Can it be made with zircons?
