Yes! All purchases are covered by a 2-year full warranty period and enjoy a lifetime warranty on fair wear and tear after the passing of the first two years.

During the 2-year full warranty period, any accidental damage done to your jewelry will be fully covered, except for gemstone damage (such as scratched or lost stones). We will also cover any manufacturing defects.

The lifetime warranty period starts two years after your purchase was made and covers jewelry maintenance and any damage caused by fair wear and tear. This includes:
- Repairing minor scratches and scuffs
- Inspection and maintenance
- Cleaning and polishing
- Prong tightening
- Rhodium replating

Any damage not classified as fair wear and tear, such as a broken chain or bent ring, will incur charges upon repair.

Our warranty does not cover lost or damaged gemstones, theft, loss, breakage, negligence, abuse, unauthorized modifications, or ring resizing.

Please contact us at for any warranty-related inquiries, and include photos and receipts of your purchase whenever relevant. Claims will be reviewed on a case-by-case basis.

We buy back any Nyssa jewelry at 20% of the initial purchase price in exchange for store credit. Please note that you are responsible for the shipment fee when shipping your items to us. After receiving your unwanted items, we will credit your customer account accordingly. We will recycle your jewelry and convert it into new designs to be enjoyed again and again. Contact us at to make use of our buyback program.

We want our customers to shine in our jewelry with complete confidence. If, for any reason, you’re not completely satisfied with your purchase, we’ll be happy to offer a refund on any purchase for up to 30 days after your item was received.

All jewelry pieces, including made-to-order, are eligible for return and a full refund. Your item will have to be returned in its original packaging and in the same condition in which it was received to be eligible for a refund. Please note that sales of engraved pieces are final and no return will be accepted.

You may visit and select the piece(s) you want to return to generate a return label. The cost of return shipping will be deducted from your overall refund, and this fee varies depending on where the return is shipped from. The fee will be calculated on a case-by-case basis as you go through the return process.

After receiving your return request, we’ll send you a payment request for the return shipping fee. Upon receipt of your payment, we will email you the return shipping label. You will receive a refund to your credit card within about 7 business days after we have received and approved your package.

Please note that we are not responsible and unable to return duties and taxes (if any), as well as the original shipping charges.

Unfortunately, we are unable to accept product exchanges at the time. You may return your purchase to us and use your refund to place a new order for the item you would like instead.

You can edit your order details within 1 hour after placing the order, or you may cancel the order before it is shipped out by calling us on +852 5726 2918. If you miss the deadline, you may return the order within 30 days of receipt. Please keep in mind that we’re not able to cancel orders that include engraved items as they are immediately processed.

Some of our 9-karat solid gold jewelry can be upgraded to 18-karat solid gold for a little extra luxury, or vice versa. When a product is labeled as made-to-order, it means that we do not hold it in our inventory. Our master jewelers will create the item especially for you when you backorder something. All made-to-order pieces ship within 15 business days to give our jewelers sufficient time to complete your order.

Please allow an extra 1-3 business on top of our regular processing time of 1-2 days to complete your engraved orders.

Some of our items can be engraved, as indicated on the product page. The number of characters that can be engraved varies per product, so please check the individual product pages for more detailed information on the engraving. Our engravers will choose the most suitable location for your personalized message.

Follow this 3-step guide to find your perfect fit at home in less than a minute. All you need is a pen, a ruler, and a piece of string (like dental floss or a ribbon) to measure the circumference of your finger.

Prep your finger for measurement by making sure it’s warm (cold hands shrink) and at a normal size (fingers swell at the end of the day). Different fingers have different sizes, so make sure to measure the exact finger you plan to wear your new ring on. Now let’s get started.

1.Wrap the string tightly around the base of your finger, making sure to leave enough room for your knuckles
2. Mark the point on the string where the ends overlap with a pen
3. Measure the length of the string in millimeters up until your pen-mark using a ruler

Et voilà, your ring size (European) is:

Diameter (mm) Size
16.0 50
16.23 51
16.45 52
16.9 53
17.3 54
17.51 55
17.7 56
18.14 57



We offer worldwide shipping to any destination. Please note that we don’t ship to P.O. boxes.

We ship out all ready-to-ship orders within 1-2 business days, or 2-5 business days if your order contains engraving. Orders that contain made-to-order products ship within 15 business days.

For orders shipping to countries in Asia, shipping typically takes about 4-7 business days. For international orders, the shipping time varies depending on your destination.

The shipping fee for orders that do not meet the minimum amount stated above will be calculated during the checkout process, as it varies per shipping destination.

We ship all orders from Hong Kong.

You will receive a shipment confirmation email from us containing a tracking code shortly after your order is processed. You may track your shipment on our logistic partner’s website.

Your local customs office may charge duties and taxes on your order upon delivery, depending on your country’s law, VAT, and other import regulations. Nyssa has no control over these charges and is not responsible for their payment.

If your order is subject to international shipment duties and taxes, you will receive an email from our courier with further instructions and a link to settle the charges. Please take action promptly if you are requested to pay for import charges to ensure that your order passes customs clearance quickly and arrives timely.

If you choose not to pay outstanding duties and taxes, your order will have to be shipped back to Nyssa at your expense, and you will have to submit a refund request.

Materials & Care

We’ve searched far and wide for the highest quality and most sustainably-sourced materials for the creation of our jewelry pieces. Our fine jewelry is handcrafted in either 9-karat or 18-karat solid gold, vermeil, or rhodium-plated 925 sterling silver. Our solid gold is recycled or sourced following Fairtrade standards. We finish our jewelry with eye-clean and colorless diamonds, certified conflict-free following the Kimberley Process Certification Scheme, and ethically-sourced natural gemstones. Interested in learning more about each of these materials? Visit our Materials & Care page for more details.

Yes! We exclusively work with conflict-free diamonds. All of our diamonds are Kimberley Process certified to be 100% sure that they do not fund violence.

The Kimberley Process Certification Scheme (KPCS) was founded in 2003. Its mission is to prevent conflict diamonds from entering the global market by regulating the trade of rough diamonds. The KPCS promotes transparency within the industry and fosters collaboration between its members, NGOs, and the UN. The Kimberley Process has been successful in its mission: its participants have already prevented 99.8% of the global trade in conflict diamonds. The scheme is pushing towards 100% by working on developing innovative new measures and expanding its network of member states.

Great news: our jewelry requires very little care, as it’s crafted out of only the highest quality materials. Solid gold does not tarnish or rub off, making it a very durable material. We recommend cleaning your solid gold and vermeil pieces regularly by wiping them with a soft cloth. For a deeper clean, use warm soapy water and a soft cloth or old toothbrush to gently rub your gold pieces, and make sure to dry them properly after. Silver jewelry can be cleaned with special silver polish. Head over to our Materials & Care page page for more fine jewelry care tips.

No, we promise you won’t find a trace of nickel in any of our products. We only work with solid gold, vermeil, and rhodium-coated 925 sterling silver.

Gift Cards & Store Credit

Yes! We offer digital gift cards in different values to suit all budgets: US$50, US$100, and US$200. You may purchase a gift card here. The gift card will be sent to the recipient’s email address immediately after your payment is received.

On our website, proceed through the checkout process as usual, but when asked for your payment method, enter your unique gift card number in the field labeled ‘Gift card or discount code’. The total for your purchase, plus any tax and shipping fees, will then be deducted from the value of the gift card. If you want to make a purchase valued higher than your gift card value, you can use a credit card to make up the difference.

Nope! Our gift cards don’t have an expiration date.

Sorry, we’re unable to transfer your store credit to a different account.
