Apparently, when tombs were raided in the ancient world the first things to be stolen were the perfumes and unguents.
+1 -That is not surprising. In the Christmas story, we find the Wise Men bringing gifts of Gold, Frankincense, and Myrrh. It is an indication that the fragrances were valued as highly as gold. Perfumes and resins have been used since ancient times in religious rituals, including burial. The same can be said today. Natural Ambergris, Oud, and Oris are perfume ingredients that are more expensive per kg than gold. That is why most shaving products include synthetic versions.
BTW: According to YouTube, the most expensive perfume in the world is DKNY Golden Delicious Million $ Fragrance Bottle. It costs $1 Million per ounce, but the diamond studded bottle is a significant portion of the cost.
