Questions, answered

Everything you need to know.

What is the visual difference between 1.0 CT and 2.0 CT?

The 1.0 CT option has a more understated presence, while the 2.0 CT option gives the round centre more coverage on the finger. Use the comparison images as a relative guide; exact dimensions vary with each diamond’s proportions.

Which metals can I choose?

Promesse d’Amour is available in Platinum 950 and 18K White Gold. The specifications update to reflect the selected metal.

Which ring sizes are available?

Choose one of the listed fixed sizes or Custom Size (made-to-order). The selected value appears in the ring specifications.

Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds have the same chemical and optical properties as mined diamonds; the difference is how they are created.

Are the diamonds certified?

Yes. Every lab-grown diamond is certified by the International Gemological Institute (IGI), and you can verify its report on the official IGI website.

How do I choose the correct ring size?

Use our Size Guide to compare an existing ring or measure the intended finger. If the proposal is a surprise, choose a Size Adjustable option when it is available for the design you like. Otherwise, select your best estimate and we can resize the ring free of charge after the proposal.

What if the ring size is wrong?

Not a problem. Contact us after delivery and we’ll arrange a complimentary size change for you.

How long will delivery take?

Free insured FedEx delivery usually takes 5–7 days for in-stock rings. Made-to-order rings require 1–2 weeks for production. If your order is urgent, contact us to ask about 1–3-day delivery with DHL Express.

Are shipping and returns free?

What does the lifetime warranty cover?

All our products are covered by a lifetime manufacturing warranty against defects and manufacturing faults. Contact us if you would like more details or need help with an item.

Is delivery insured and discreet?
