Every purchase is protected by a reassuringly comprehensive set of guarantees

We know that diamond jewellery represents a significant investment, so we aim to provide you with a level of reassurance nobody else can match. In short, we completely eliminate any element of risk so you can buy with complete peace of mind.

Our unique set of guarantees go far beyond simply offering 100% satisfaction or your money back. We also replace items free of charge if you buy the wrong size and even offer a complimentary one-time repair service, just in case.

Satisfaction Guarantee. 100% satisfaction. Or 100% money back.

In the highly unlikely scenario that your Montluc diamond jewellery fails to live up to your expectations, simply return the item to us within 30 days of receipt. We will fully reimburse you with the minimum of delay and with no questions asked. This guarantee is not applicable to pieces made with our Atelier service, or for Stellar rings containing diamonds larger than 0.5ct.


Fitting Guarantee. Try this one for size.

Maybe the ring was a gift for somebody special. Or perhaps you weren’t entirely sure which size to go for. Either way, it isn’t an issue. If your ring doesn’t fit as expected, simply return the original to us and we’ll redeliver your perfect fit, super fast.


The unique Montluc ‘Oh no!’ Guarantee. Because sometimes it just isn’t your day.

Accidents happen. So if you’re having one of those days that somehow makes it inevitable that you’re going to drop, crack, scrape, or scratch your Montluc jewellery… relax. Return your item along with all detached bits and pieces and we’ll send you a brand new replacement completely free of charge. This guarantee is valid for two years from delivery.

If you ever need to activate your Montluc guarantee, please email us at customerservice@montluc.com  

The Montluc ‘Oh no!’ Guarantee is simply unique, offering a one-time repair and return service if you accidentally damage a piece. Nobody else offers this level of reassurance.”
