“Made to order” means that the product is only made when an order is placed requesting it. In our cases, we begin the production after we receive an order from you, and the jewelry will be made exactly according to your choice of material and size.

A 4-6 weeks turnaround means that once you place your order, it takes 4-6 weeks for your item to be handmade at our studio.

For made-to-order rings, the average production time is 4 to 6 weeks. We do our best to have your ring ready as soon as possible. However, we want to ensure your ring is as perfect as it should be, so we would truly appreciate it if you could give us enough time to make it just perfect.

It is hard to keep track of an individual order as there are lots of orders being handled at the same time at our studio. Therefore, we do not typically send email updates throughout the production process.  However, we will contact you by email if there is a problem with your order or an unforeseen delay.

An order confirmation email with details of your order will be sent to you right after we receive your order. Please make sure to check your spam folder if you cannot find one in your inbox.

If you haven’t received any email confirmations about your order, it is likely the emails were marked as spam or that the email address you entered contains a typo. Some email providers may mark our emails as spam or completely block them. Be sure to check your spam folder for emails about your order, and make sure to add Sunday Island Jewelry to your safe list. If you have questions about your order, please feel free to reach out to us by email.

Yes. Simply add this “Sizing Upgrade Service” to your cart and pay together with the ring:

We highly recommend you to go to a local jewelry store to have your finger measured, or purchase a standard ring sizer from a reputable retailer. Please do NOT use a paper or string to measure your finger since that may result in inaccuracy.

If you use a different type of measurement that is not US ring size, please refer to this standard international conversion chart:

If you are trying to buy someone a ring as a surprise but don’t know his/her ring size, you may try “stealing” one of her existing rings and have it measured at a local jeweler to get an measurement.

If all above fails, you may consider to order a US size 7 which is the most common size for an adult woman. You may have to resize it later if the ring does not fit him/her perfectly, in that case, please refer to our resizing policy.

All of our gemstones (except Alexandrites) and diamonds are genuine unless otherwise stated in the product description.  We source the stones ethically from the most reputable sellers that we can find.

By nature, some gemstones are not eye-clean and may contain minor flaws and internal inclusions, please embrace the slight imperfections that makes each piece unique and beautiful in its own way

18K = 75% pure gold (25% other metals)

14K = 57.5% pure gold (42.5% other metals)

Tips: If you are sensitive to nickel, the safest option is to order a platinum ring which has 95% platinum and 5 % other metal.

We can’t change anything once the production begins. However, it is possible to resize your ring at a cost before mailing it to you. Most of our rings can be resized to be 1.5 sizes larger or smaller. In this case, please contact us by email to get further assistance.

It’s essential to determine your correct finger size before ordering. Most of our rings can only be resized up or down by about 1.5 sizes. Otherwise, it may require a complete remaking of the ring, and the cost of remaking a ring is 40% of its original price.  If you need your ring resized, please get in touch with us by email. The cost of resizing ranges between $100 to $150 per ring, plus shipping both ways.


All Sunday Island pieces are displayed and charged in USD.


However 100% upfront payment is always recommended for all purchases as setting up layaway plans creates hassles for both parties and requires excellent coordination between both sides. Before you contact us for a payment plan, please consider whether you can put the total amount on your credit card and pay it off later at your own pace.

To set up a payment plan:
We require at least 60% payment before making any item. Therefore, production will only begin after 60% of the total amount is received, and the rest of the 40% will be due before the shipment of your order.

If you are interested in a payment plan, please let us know the information below:

1. link to the item you are interested
2. your interested gold type (14, 18k or platinum; rose, white, or yellow gold color)
3. your ring size
4. when you would like to make the first down payment

All items will begin production after 60% of the total payment is made and ship after 100% payment is received.

The buyer needs to complete the payment plan within 5 months from the day we receive the upfront 60% payment.

Please note, if an order is canceled at any point before shipment,  a restocking fee of 40% (of the item’s total price) will be subtracted from your refund .


Since most of our items are handmade-to-order(custom-made products), there are typically no returns or exchanges unless there is a crafting or production defect with the item. Please contact us via email within 3 days of receiving the product if you received an item that had a defect and we will work together with you to resolve the issue without any hesitation. If the defective item can’t be repaired or replaced, we will issue a full refund once the item is shipped back to us in it’s original conditions.

If you would like to return your fault-free order for a personal reason, please contact us via email within 3 days of receiving the item to get your request considered on a case-by-case basis.

We reserve the right to decline a return if the item shows signs of wear, has been altered in any way, or if the return is requested after the allowed 3 days. Engraved items and orders with special custom changes are not eligible for return. Discounted items are final sale and are not eligible for return.

Cancellation within 24 hours of purchase

You can request a cancellation within 24 hours of purchase. However, a cancellation will incur a 5.5% cancellation fee due to the payment processors charging a 5.5% processing fee and not refunding us for canceled orders. If you request a cancellation within 24 hours of purchase, you will receive a 94.5% refund back.

Cancellation after 24 hours of purchase

After 24 hours, your order will go into production, and we can no longer stop the production process. Please note that the amount of time and effort we spent on each order can’t be canceled. Therefore there will be a restocking fee of 40% for all cancellations that are requested after 24 hours.

We try hard to create the best quality jewelry and they are supposed to last for generations. Taking care of your jewelry is necessary if you want to keep the lifespan and longevity of the “new” quality in your purchased jewelry.

If your jewerly gets damaged accidentally, you are welcome to contact us via email. Don’t panic, most of the time, the ring can be repaired.

There will be a small and reasonable fee (normally between 100USD to 150USD for issues that are unrelated to the center gemstone) for reparing or cleaning your jewelry. The cost for shipping is your own responsibility, both to us and back again.

If the main stone is damaged permanently
In most of the cases, we are able to help you source a new stone and re-set it.  However, the cost of replacing a new stone will cost about 25%-35% of the original price. Please refer to our care instructions to avoid any potential risks of damaging your jewelry.


Remove your jewelry before hand washing, showering, gardening or doing outside work, using cleaning chemicals, applying makeup and lotions, swimming, and exercising. Exposure to any harsh chemicals or heavy pressure will put your jewelry at risk.

You can normally clean your jewelry at home with water, gentle soap, and a soft toothbrush. (exception: Ethiopian opal gems)

Your jewelry contains one or several Ethiopian Opal gemstones
Ethiopian Opal is a delicate stone that requires the wearer to take care of it properly. They are considered hydrophane opals and have the ability to adsorb water or liquids. A contact with water, chemicals, oil or heat may result in a discoloration or a permenant damage. Please do not wear your opal jewelry while cooking, washing hands, taking showers, swimming or any physical activities that will put the stone at a risk of damaging. After every wear, the best cleaning method for Ethiopian opal jewelry is to use a clean, soft, dry microfiber cloth to gently remove dirt, residue, and oils.

Australian Opal gemstones
Australian Opal can be cleaned by soap water and a soft brush. Just avoid ultrasonic cleaners and chemical cleaners.
