The preferred and most accurate way to ensure you are ordering the correct ring size is to visit your local jeweler or jewelry store to get sized with a professional ring sizer. You can also order a plastic ring sizer from us.

For an at-home solution, access and follow the instructions on our sizing chart - download and print PDF here.

First and foremost, we encourage you to get properly sized by a jeweler/jewelry establishment prior to placing your order. Rings are are made-to-order according to your specific ring size. Not all ring mandrels (what is used to measure a ring's size) are created equal, and they can vary by 1/4 of a size. If you need your ring resized by 1/4 of a size or less, resizing is complimentary (less shipping fees).

If you need a size alteration greater than 1/4 of a size up or down, a $60 resizing fee applies for Sterling Silver, 14k, and 18k. A $100 resizing fee applies for Platinum. All shipping costs are the responsibility of the buyer. Resizing is available for most ring styles, but be sure to email info@mhisae.com to inquire about the eligibility of your specific piece. Turnaround is approx. 7-10 days.

All items exceeding $200 USD are FINAL SALE. Orders totaling less than $200 USD may be returned or exchanged within 14 days of receipt for an item of equal or lesser value or credit toward a future purchase.

USPS and UPS

All items in the online shop are solid Sterling Silver, 14k Gold, 18k Gold, or Platinum. M. Hisae does not use any plated or metal clad materials. Brass is offered only as a sample material for at-home try ons. All castings, sheet and wire are are certified 100% recycled metals. Visit the Studio & Materials page to learn more. 

If worn regularly and stored in sealed compartments when not being worn, solid Gold and Sterling Silver keep well and require little care. Should they be left unworn for longer periods of time, exposed to humid air, or come in contact with lotions or oils, tarnishing may occur.

For best results, wrap pieces individually in soft cloths and store them in sealed ziploc bags. Metals do interact to cause tarnishing, so separation is key.
