We are able to make some alterations in size to pieces on our website so please do get in touch to discuss this and we will do everything we can to ensure a perfect fit. However, as each piece of jewellery is unique and set with an ancient element, we cannot guarantee that alterations will always be possible. 



Shipping costs are calculated at checkout. Your purchase is completely insured by Kallos until it arrives with you safely. 


If preferable, any purchases can be collected in person from our Mayfair gallery. Just email us at info@kallosgallery.com to arrange collection.
