Similarity is based on note and accord overlap, not molecular analysis.
Differences come from accords and community votes on longevity and sillage.
The main accords of Omnia Crystalline Eau de Parfum are powdery and floral. It opens with Lotus and Mandarin Orange, reveals Heliotrope and Orris Root at its heart, and dries down to Musk and Siam Benzoin. It lasts a moderate time and projects moderately; people reach for it in spring, mostly by day.
