At Astteria, we pride ourselves in our excellent service and support, which of course includes our free and fully insured shipping policy. This includes worldwide destinations such as the EU, UK, USA, Canada, Australia, Japan, Thailand, China, HK, UAE, and Turkey. USA shipments are sent from New York; EU shipments are delivered from London; China orders arrive from Shanghai, while other locations receive shipments from unspecified sources. The estimated delivery time is generally one to seven days, depending on the destination and the location of the specific item. Shipments can only be delivered to addresses. POB shipments are not possible, as signatures are required upon delivery.

Import duties/custom clearance fees are included in the price for deliveries in the USA, UK, China, and HK. While they are not included in deliveries to other countries, we are happy to help our customers find out about the fees in their specific country and region. VAT/sales tax differs from country to country. In the USA, it is not collected by us in most states. It’s the customer’s responsibility to pay the taxes. In the UK, the VAT is added to the price at checkout.

We offer a 100% money-back guarantee within 30 days of receiving the product. Customers from countries other than the USA, EU, UK, China, and HK need to receive the custom duties refund back from their local authorities. Additionally, we provide free return shipping in the USA. Regarding the rest of the world, the customer should contact us for more information.

Yes, all of our diamonds and gemstones are ethically sourced and come from conflict free regions. We are a proud member of the World Federation Diamond Bourses (WFDB) and we comply with the Kimberley Process.

Yes, in addition to our diamond jewellery, we also sell loose diamonds. If we do not have what you are looking for in stock, we’d be happy to source it for you.

The short answer is yes. Most rings can easily be resized for free. In some cases, resizing is not an option but we can create a new ring for you. However, sometimes this will entail an additional fee.

When a bracelet is too big, it can be shortened for free. However, when it is too small, it will generally cost to make it bigger since this almost always requires extra stones or gold.

Most of our diamonds and gemstones come with a certificate. The certification of every item can be viewed on the respective product page. Most items are either certified by the GIA (diamonds) or by the GRS (gemstones).

We offer a 100% money back guarantee within 30 days of receiving the product. Please refer to our return policy for exact details.
