Flower Collection
Flowers are a timeless classic. Their simplicity translates over to how ONTOO strives to design with simple, beautiful shapes and precision. This collection is based on traditional French enamel technique, the pieces are available in different sizes and colors in rose gold, added up with colorful semi-precious stones. The flower design dresses up during the day and with an ONTOO drop or stone the same piece of jewellery can be simply upgraded for the evening.
