Based on the glamour and magnificence of the jewels worn by Catherine the Great, comes Lydia Courteille's, Scarlet Empress Collection. Rubies. Spinels, red metal, it's all here. While her website is cryptic in terms of information, you'd have to actually contact them in Paris as they are only interested in actual buyers--and not so much the window shopper, which most of us are!
Good luck ladies in getting this or something similar on your finger from your husband.
