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. In order to receive the full refund one must provide the following:
  • The certificate that is included with the item
  • An undamaged item
Please note that Bespoke items that are returned will have 50% of the setting cost deducted from the refund.
At Astteria, buyer satisfaction is vital to us. This is the reason that we offer a diamond jewelry upgrade service. If you purchase any diamond piece from us and would like to change it at any time in the future for a higher-priced diamond piece, you will be able to use the full value of the original purchase towards the diamond piece you have chosen. To be eligible for the upgrade program, please note that the following criteria must be met:
  • Lifetime upgrade only available for any jewelry piece that we sold except for loose diamonds.
  • The new item's price must be at least double the price of the original item.
  • There are no discounts for the new item.
  • There is a mandatory 250 USD renewal fee.
  • In order to receive a refund for an upgraded item, the new item must be returned within 10 days. After this time period, we cannot guarantee the availability of your original piece of jewelry.
  • Custom order upgrades require one to return the original custom order and pay the difference including the upgrade fee, plus 50% of the cost of the setting.
Requests to reserve items can be done from the product page. However, this is subject to approval.
Appraisals are conducted by Astteria (based on retail price) for every order and are signed by a certified gemologist.
Most of our items come with a gemological report (usually GIA for diamonds, GRS/Gubelin for Gemstones.) The relevant certification can be found on each product page. If you have any questions regarding the certification, please do not hesitate to reach out for assistance.
We provide a one-year warranty for all jewelry pieces and will fix any type of manufacturing defect for free, excluding the cost of lost diamonds. If it wasn’t caused by a manufacturing defect we will notify you regarding the type of repair that is needed and whether or not it will be at cost. Astteria will not honor the warranty of a jewelry piece that was maintained, repaired, or resized by anyone other than Astteria. We do not provide a warranty for jewelry pieces damaged through typical wear and tear or when worn and used incorrectly.
Astteria accepts a variety of payment methods:
  • Money Wire - 5% off the website price
  • Credit Cards - All cards are accepted
  • Domestic Personal Checks - 5% off the website price
In order to make a custom order, payment must be done through a bank transfer or credit card. Refunds for such items do not include 50% of the set cost.
We offer a free ring resizing when possible, depending on the design, the current ring size, and the requested size.
Shortening a bracelet is free of charge. Lengthening a bracelet, however, usually requires extra payment due to additional stones or gold that are needed.
Astteria will consider buying your used diamonds when the following criteria are met:
  • A GIA certificate is provided
  • Clear pictures/videos are available
  • An asking price is submitted
We accept visitors by appointment only in the following locations: London, HK, New York, Tel Aviv, and Shanghai. Inspection in our offices or in 3rd party premises (like Brinks) is possible. The customer is required to cover the costs of the stone transfer when no purchase is made.
At Astteria, we value our customers’ privacy and do our utmost to maintain the highest level of privacy achievable. Astteria will never reveal any personal information regarding our clients. Furthermore, any personal details submitted via our website will remain secure, like any other highly secure website. Certain pieces of information, however, may be used for collecting data such as device and browser information, general location information, and information gathered through web server logs.
