Can I order Phone or by e-mail?
All orders must be placed through our website.
How long will it take until I receive the product?
In-stock items will be shipped within 1-2 business days. Waiting time estimates for out-of-stock items (and sizes) are listed on each product page. Please note that shipping times may vary, and depend on your location and the shipment method selected at checkout.
What is “lead time”?
Lead time is the time we need for production only, and it does not include time for shipping.  Please make sure to select an appropriate shipping option at checkout.
I just remembered our anniversary next week! Can I rush the order?
That depends on your order. Please contact us if you have a set date and we will see what we can do – but it is always better to plan ahead.
Can I pick up my order at your location?
We can happily welcome you to our showroom for pick up. Please contact us to set up an appointment. Hours are limited and must be coordinated in advance.
Are there any special offers?
We occasionally hold sales and promotions. They will be announced by our newsletter and also posted here. Please make sure to subscribe to our newsletter so you do not miss any opportunities.
Gold and Diamonds
I am interested in your engagement rings. Can you tell me where the diamonds are sourced?
We use various sizes and colors of diamonds and they each have different origins. Please contact us with your question and the exact item number for more detailed information. Either way, we only use conflict-free diamonds for all of our pieces.
Your White Gold option does not really look “white”. Why is that?
While most jewelers put rhodium plating over White Gold to make it look whiter, we like to keep the original color of the natural gold. Therefore, it appears rather creamy yellowish or grayish than purely white. This gives it a natural and unique look, and this is what we – and many of our customers – love about it. With that being said, you would also not have to re-plate it as you would with most White Gold jewelry from other stores.

Ring Sizing
How do I find out my ring size?
The best way is to come to our showroom to have us size you in the style(s) you are interested in. If this is not an option, we would recommend that you go to your local jewelry store and get your finger sized with a band which has a similar width/thickness of the ring(s) you are interested in purchasing.
I do not know US ring sizes.
Please refer to a ring size conversion site like this one or this one.
I am planning to propose to my girlfriend with your ring but I have no idea what her ring size is.  What should I do?
Firstly, you should select a ring which can be resized, because some of our rings are not resizable due to their unique design. If the ring you purchase does not fit, there are two options: resizing or exchange. To qualify for an exchange, however, you need to select an in-stock size in the first instance, because any, and all, out-of-stock sizes will be specially made for your order (special order) and will, therefore, be a final sale. Please read the details in our Return Policy.
I have my mother’s ring and want it remodeled. Do you take care of that?
Sorry, we are not doing any remodeling or resetting at the moment.
I love your ring R0000 but would like it a little thicker. Can you do that?
We have already given you countless choices! Feel free to be creative when choosing the right style, color, and stone, but please do not ask us to change the design. Everything we carry and create was thoughtfully designed by Satomi Kawakita, herself, down to the last tiny detail, and what you are looking at is the absolute final design.
Do you do custom work?
Unfortunately, we are currently not doing any custom work. Thanks to the support of customers like you, we are very busy keeping up with orders for our current collection.
I love your ring but would like to use my own diamond. Can I buy your setting alone?
Our apologies, but you cannot. We sell complete pieces only.
I want my newborn son’s name inside of a ring. Can you do that?
Yes, we offer engraving services for our items as long as it is technically possible (some pieces are just too small). Please see the engraving service page for more details.
Product Information
Are all your jewelry pieces made in New York?
Yes. All pieces are carefully handcrafted by Satomi and her team in her studio in the heart of New York’s TriBeCa neighborhood. There will be slight variations in some items because of their handmade nature and we appreciate those who value our craftsmanship, devotion, and commitment to every single piece created in our studio.
There is a ring that I want to try on, but I cannot find it at any of your retailers. What should I do?
Our NYC showroom is open for those who would like to see our collection – we have our entire collection here including pieces that may be unavailable at your local retailer. Please make an appointment through this page.
I saw one of your pieces on Pinterest but cannot find it on your website. Where can I buy it?
Unfortunately, that means it is not for sale anymore. These pieces have either sold out or are now discontinued. Our apologies for any inconvenience, but there are many other beautiful pieces available, and moreover, new pieces are constantly being designed!
I have a question about one of your rings. May I call you?
Believe it or not, jewelry studios generally have a lot of noise going on due to banging, shaving, polishing, etc. If you could e-mail us rather than call, you will receive your answer in a prompt fashion. Additionally, we always prefer communicating via e-mail in order to avoid any miscommunications or misunderstandings.
Do you offer gift wrapping?
All of our products are perfectly presented in a beautiful paper jewelry box whether it is a gift or not. If you are looking for something nicer for your special occasion, there is an option to upgrade the ring box. If you would like us to remove all prices from any included receipts, please select the gift wrapping option at checkout – please note, however, this option is only valid for domestic customers due to international Customs requirements.
Can I purchase insurance with an engagement ring?
We can issue an appraisal that you may submit to your insurance company. Please contact us for details.
I am eager to get one of your completely unique rings. When will they become available again?
We release new One-of-a-Kind pieces occasionally. Please check our new items page. The best way to find out about any of our new designs is to register your e-mail address for our newsletter, so you do not miss these unique items when they become available.
I purchased a pair of studs but they are smaller than I thought they would be. Can I return them?
Sure – but you can only return them if they were an in-stock item to begin with, as per our Return Policy. Please read the product descriptions for in-stock status before you purchase an item. These descriptions contain as detailed of an explanation as possible.
I am wearing your ring but it feels a little too tight. Can you make it bigger?
A ring sizing service is available with a fee and shipping costs, but some of our rings are not resizable because of their unique design and materials. Please check our product descriptions to find out for which items resizing is applicable for. Prices vary depending on which style and how big or small the correction is. For further information, please contact us. Please note: we are not responsible for any deformation or discoloration of your jewelry if you happen to take it to a local jeweler for resizing, without consulting us in advance.
My kid accidentally broke my earring and I realized one of the diamonds fell out. What should I do?
Please visit the After Purchase page for our Repair Service section.
I purchased your ring from one of your stockists and want to exchange it for another one. Can I bring this to your showroom?
Our return/exchange policy only applies to items that were purchased directly through us. Please contact the store you purchased your item from and work with them accordingly.
I just purchased one of your necklaces and would like to keep it looking as beautiful as it looks right now. Do you have any advice?
Please refer to our Product Care section on our After Purchase page.
My husband bought me a ring from your studio, but it is too small and I would like a pair of earrings instead. Can I exchange it?
If the ring your husband bought was an in-stock item, it can be returned – so long as we are contacted within 5 days of the item’s receipt – so please contact us to receive a Return Authorization number and further instructions. However, if it was an out-of-stock item, that means it was a special order made especially for you and is non-returnable/non-exchangeable, per our Return Policy. We will check if the ring can be resized, so please contact us with your purchase record in this instance.
