These beautiful pieces are entirely hand painted. This elegant and noble pattern is Cobalt Net and is one of their most popular patterns. The painter Anna Yatskevich created this pattern in 1951 and since that time Cobalt Net pattern is in a production line at the Imperial Factory. The cobalt blue is one of the factory's signature colors. It is so vibrant and beautiful! With a set of three you can keep two for a tea party with a friend and gift one set to someone special!

It has the red LFZ monogram export backstamp with red "Made in Russia" used from 1991 to 2002. Due to the hand painted aspect it is recommended that the porcelain be hand washed in warm water with mild detergent. All of my listed Russian Porcelain was purchased in 2001 directly from the Factory in Russia. I had planned on opening a tea room and having this amazing porcelain available. But the tea room never opened and every piece has been in storage since purchasing (22 years ago). All pieces are authentic Russian porcelain, all but two pieces have the burgundy colored 1992 - 2002 mark, two pieces have the “domestic” mark (logo only) and one piece has the 2002-2006 mark. The pieces are all unused, in new condition, no chips, marks, nits etc. The pieces are new and not copies (which the factory started making in 2005).
