One of the gifts I got on my birthday — Amethyst necklace also accompanied by earrings :) Made by Авторские украшения Анны Садовой
And last year I got this great set http://www.bussinka.com/komplekty/183-zhemchuga-korolevy.html also made by Anna Sadovaya.
She makes wonderful things, pleasant to watch and to wear, so here are my best recommendations, especially for guys looking for a gift to their sweethearts, sisters, mothers, cousins, girlfriends, etc. for the 8th of March ;)

Anna.
