Guerlain's fragrance Precious Heart for Women was introduced in 2004. What is the scent of Precious Heart? It's an aroma with a mix of aromatic citrus, flowery, and fresh scented tones that will leave you feeling fresh, sensuous, and exotic. When you examine it more closely after it has been applied, you'll detect a lingering quality of gentler fragranced woody, green, and powdery hints that conceal an essence of uplifting, pure, and delicate sentiments.
