ON + TOO

Customise your jewellery

Luxury that adapts to you.

At ONTOO, we believe that jewellery should be as unique and multifaceted as the women who wear it. That’s why every ONTOO piece is designed with versatility and personalisation in mind — made to be added onto, layered, adapted, and elevated over time.

How does customisation work?

First things first, connect with our team using the form below. Include as many details as possible. If the alteration is more complex we suggest booking an appointment for a physical or virtual meeting.

How much does it cost?

Each custom-made piece is priced individually depending on your specific design and materials. There are no additional charges for any alterations or adjustments.

Can I design whatever I want?

At ONTOO, jewellery is deeply personal. You can customise materials and stones that resonate with you. While designs aren’t fully open-ended, each piece is based on an original ONTOO design, thoughtfully adapted to your unique style and preferences.

Timeline

Once your order is approved, production and delivery typically take 2–4 weeks, depending on the selected stones and materials.
