Tubereuse or Tuberose is by far, the uncontested No.1 best selling fragrance on the list of Diptyque products. Tuberose is a very sensuous, heady scent, derived from a Mexican bulbous herb. It is also the most expensive floral perfume ingredient in the world. The matching Eau de Toilette is Olene. Available in candles, room mists, burning oil essences, and matching eau de toilette and hair and body wash. Diptyque Burning Oil Essence is a concentrated home fragrance oil for use with our light bulb ring diffuser, to refresh a potpourri, or simmer in our pillar oil burner. Each kit contains a 0.5-oz flask of oil, dropper, and ring diffuser.
