If for any reason you are unable to sign for your delivery in person, or choose to waive the signature in any other way, you agree to our terms and conditions and take full responsibility for any loss or damage that may occur.

You will become the owner of the goods you have ordered once they have been dispatched to you. Once goods have been delivered to you they will be held at your own risk and we will not be liable for their loss or destruction.

If your order is returned to us because the courier or postal service could not complete the delivery to you for whatever reason, then you will be responsible for the repeat delivery costs.

We reserve the right to cancel an order if:

1. We have insufficient stock to deliver the goods you have ordered;

2. We cannot deliver to your area; or

3. One or more of the items you ordered was listed at an incorrect price due to a typographical error or an error in the pricing information.

Product Care

Dust, pollution and daily wear can all add to the gradual dulling of your beautiful jewels. The brilliance of a gemstone can become clouded and the surface of platinum and gold lose its shine.

We suggest that your jewellery receive periodic professional maintenance. You can take your pieces to a local jeweller to be cleaned, or contact our Client Services team and we can organise this service for you.

Most diamond and precious stone jewellery (with the exception of opals and emeralds) can be cleaned in warm water, using a mild detergent such as Fairy Liquid. You will be surprised at how effective this is. You can also use a very soft toothbrush to get into any hard-to-reach nooks and crannies. Always dry your jewellery after cleaning with a soft cloth.

General wear and tear can cause stone settings to loosen over time. If your piece does include precious stones, we recommend a setting-check approximately every two years. This is a service we offer and you can contact Client Services for further information.

Since many genuine gemstones and especially pearls are quite delicate, hot water, harsh chemicals and cleaners should be avoided at all times.

Never use a liquid jewellery-dip to clean your piece - these commercial products can cause lasting damage to metal and stones. Should you wish to polish your piece yourself you can use a jewellery polishing cloth. These are available from most jewellers, or we can organise getting one to you.


Credit cards

We accept VISA, Mastercard and American Express as credit card payments. Hannah Martin does not charge the credit card as this is on hold until the package is dispatched. However, the order amount will be deducted from your credit card by the time you place your order.


You can also pay with a PayPal account, which you can log into or register for. PayPal stores your card and bank information, enabling you to pay without sharing your payment details with Hannah Martin.
