Zarina is a well established chain of jewellery suppliers with 30 stores currently operating in Ukraine. Their main focus is to provide customers with exclusive pieces of jewellery in their dedicated stores. Along with the unique quality of its jewellery, Zarina identifies itself through the inimitable interior design of its stores and the persuasive presentation of its jewellery. Lighting Designers at Queensland LLC, carried out numerous internal tests with different LED modules before arriving at the conclusion that Zarina’s diamonds shone brightest and most brilliantly when exposed to Tridonic’s TALEXX LED technology. In each store, Zarina’s jewellery is displayed in 33 showcases entirely made of glass and two integrated Fabergé showcases. The transparent showcases are freestanding, whereas the Fabergé showcases are directly integrated into the walls of the stores. Within the project all were equipped with Tridonic LED technology.
