Handcrafted by Slovene couple Katja and Jure Bricman, Catbriyur porcelain has long been recognised as some of the finest functional art pieces to be produced in the country. While strictly speaking their boutique in Ljubljana is more a shop than an art gallery, that doesn't mean you can't stop by to browse - just be careful you don't break anything, as many of the items are in the 'price on request' range. Distinguished by their irregular shapes and design, each cup, plate, tray, clock and piece of jewellery is literally one of kind, although there are several different series executed in the same motifs and styles. If our recommendation is not enough for you, proud owners of Catbriyur porcelain include Vladimir Putin, the King of Norway and most famously Her Majesty Queen Elisabeth II, who was presented an exclusive gold-encrusted Royal Collection tea set during her official state visit to Slovenia a few years ago.
