After-Sales Services
We are happy to provide complimentary resizing after delivery, as well as ongoing repair and maintenance services to help keep your jewelry as beautiful as possible.
Complimentary Resizing Services
The majority of our ring designs are eligible for a one-time complimentary resizing service if you contact us within 30 calendar days from the date of delivery. This includes insured shipping to and from Japan at no additional charge. However, if you are shipping items with a total price of $2,500 or more in a single shipment, you may need to file Electronic Export Information (EEI), which may incur additional costs. In this case, please message us using the "Contact Us" page before shipping your jewelry.
To make use of our complimentary resizing services, you will need to provide the Certificate of Authenticity that originally came with your ring.
Some rings cannot be resized due to the characteristics of the design, but can be exchanged for a new ring of the desired size. Requests for a second or further resizing or requests made after 30 calendar days from the date of delivery will incur a resizing fee.
Please note that some ring designs are not eligible for the complimentary resizing or exchange service and will require a resizing fee. To confirm which designs are eligible for our complimentary resizing services, please view the corresponding design page or message us using the Contact Us page.
Complimentary Resizing Process
- Send your request using the Contact Us page. Please include your name, email address, item information (design, design number, serial number), order date and order number if possible.
- A customer service representative will ask you to take several photos or videos of the ring at specific angles, as well as a photo of the Certificate of Authenticity that came with the ring.
- Please take the photos or videos as requested and email them to the customer service representative.
- After checking the photos and videos, we will let you know whether it is possible to resize your ring. If resizing is possible, we will email you an invoice and a FedEx shipping label for printing.
- Securely package your ring for shipping using the packing method shown in the video here. If you do not use this packing method and damage occurs during shipping, the insurance we provide may not cover any losses incurred. Please remember that NIWAKA has no responsibility for any losses or damage that may occur during shipping.
How to Safely Package Your Jewelry - After your ring has been securely packaged, ship it to us using the invoice and shipping label we provide.
- Please inform your customer service representative that the package has been sent.
- We will begin the resizing shortly after your ring arrives and will ship it back to you once the process has been completed. Please note that we only return the jewelry, the pouch and the Certificate of Authenticity.
*Regardless of whether the service is complimentary or paid, rings sent for resizing or exchange will be shipped back to you approximately 7 to 9 weeks after we receive them. However, the delivery time may be longer depending on the design and condition of the ring, or due to national holidays. Please note that the aforementioned resizing period of 7 to 9 weeks does not include the initial inquiry period or the shipping period to Japan.
If you are unsure about which ring size you require, Ring Sizing Kits are available for purchase to measure your Japanese ring size.
For more information, please feel free to message us using the Contact Us page.
Repair & Maintenance Services (Paid)
We are happy to provide ongoing support services, even if 30 calendar days have passed since the date of delivery of your jewelry. Depending on the design, we offer various paid repair and maintenance services such as polishing, engraving, engraving erasure and re-engraving. To make use of our repair and maintenance services, you will need to provide the Certificate of Authenticity that originally came with your jewelry. Please note that it may not be possible to fulfill some requests due to the design or condition of the jewelry, so please consult with us using the Contact Us page before sending your item.
When sending your jewelry for paid repair and maintenance services, complimentary insured shipping to Japan is not included. Please make your own shipping arrangements through FedEx for smooth customs clearance and transportation of your goods. We also recommend using transportation insurance for your peace of mind. NIWAKA shall not be liable for any loss or damage that may occur during transportation.
All paid repair and maintenance services include insured return shipping to the US via FedEx at no additional charge.
Important Points Regarding Resizing
In the case of paid resizing, one of the two approaches is used depending on the design: either resizing the ring, or exchanging the ring for a new one of the desired size. Note that some ring designs are not eligible for resizing. For details, please refer to the respective ring design page or message us via the Contact Us page.
Please be aware that eligible designs can only be resized within the limits shown under "Available Sizes (Japanese)" on the ring design page. In addition, the resizing range is determined based on the size chosen at the time of purchase, and any subsequent resizing cannot exceed this range. For example, if your ring design has a resizing range of ±3, after an initial resizing by +2, you could only request another resizing by +1 (+3 in total).
