Fashion: Make this Valentine's a ruby Tuesday

Yves Saint Laurent's gloopily gorgeous, molten-looking "arty" ring has become something of a design classic in recent years, adorning the fingers of the fabulous wherever you look. This month, the Parisian house reissues it as a limited- edition Valentine's version, with "love" engraved on the back and all the glitz and glamour of the original with a ruby-red semi-precious stone. Fall in love the French way, why not? £165, ysl.com
