I have the Polaire and Diamonds which are very good unique quality scents. I've not sniffed this. But £3.19 what's to lose. Yardley Polaire is also £3.19 for 50ml.
Yardley London Jade is a retro-inspired, fresh and elegant, green floral chypre capturing the spirit of the 60's
Top Notes: Fruity, aromatic green top notes of peach, bergamot and galbanum
Heart Notes: An airy floral bouquet of rose, jasmine, ylang-ylang and orris
Base Notes: Delicately wrapped up in patchouli, sandalwood and moss
50 ml bottle
