Opus Iv Perfume by Amouage, Opus IV, launched in 2010, is one of several fragrances in the Library Collection?. Like other members of the collection, this product is appropriate for both men and women. This fragrance is sure to get you noticed. Its citric top notes are lemon, mandarin orange, grapefruit, and coriander. Those introduce an aromatic heart of elemi, cardamom, caraway, rose hip, rose, and violet, which rest on a resinous base of labdanum, musk, and last but not least, incense, which?pleasantly lingers the entire day. The overall effect is that of warm spiciness, similar to the impression of cumin. The warmth of this fragrance makes it perfect for autumn and fall. The perfumer credited with this composition is Jacques Flori.?
