Jewelry Sizing Guide

Whether you're selecting a ring, necklace, bracelet, or earrings, it's important to remember that fit can vary based on individual proportions. Use our jewelry sizing guide to find your perfect fit. Please note the images below are for illustrative purposes only—be sure to take your own measurements to ensure accuracy. For any sizing related questions or to work with a designer, contact us at info@shahlakarimi.com.

Rings

In order to accurately size your ring, we recommend visiting your local jeweler for an in-house sizing and using a ring sizer with a comparable width to the design you're interested in. Information regarding the width of our styles can be found in the details section on the product pages. For alternative sizing methods, we recommend ordering this ring sizer or referring to our ring size chart below.

Resizing: If you are unhappy with the fit of your piece, we can adjust its size at your request. Ring resizing starts at $150+, and may increase depending on the piece. Any additional customization charges beyond resizing will be assessed on a case-by-case basis. The customer will also be responsible for the cost of insured shipping.

Please note that eternity bands (or any bands with stones set 360 degrees) cannot be resized. However, we can remake eternity bands at labor cost, typically between $300 - $500 depending on the piece. In the meantime, we recommend ordering this size adjuster for a more comfortable fit.

If you’re interested in resizing your piece, please contact us at info@shahlakarimi.com. We will provide you with a quote, including the cost of insured shipping. Once you’re ready, we’ll send you an insured shipping label to return your ring back to us.

Bracelets

Bracelets are available in a range of lengths. We recommend using a measuring tape to measure your wrist size. As a general rule of thumb, add half an inch to your measurement to find your size. This ensures your bracelet sits comfortably without being too tight.

Ear Arcs

Ear arcs are designed to fit comfortably from the inner ear to the outer earlobe. With the earring post positioned in the middle of the arc, make sure to account for any off-centered piercings when measuring and determining your size.

Use a caliper or ruler to measure the length from the inner ear to the outer earlobe. This length corresponds to the earring size or inner length of the earring. All ear arcs are available in sizes ranging from 15mm to 19mm.

For any off-centered piercings, use a caliper or ruler to measure the length from the inner ear to the piercing hole and from the piercing hole to the outer earlobe. If you want your earring post to be offset, include these measurements as a note at checkout or email it to info@shahlakarimi.com after placing your order.

If you don't have a ruler or caliper to measure, we recommend holding a credit card next to your left ear and your right ear for scale. Take photos and share them with us so we can confirm the measurements before starting production.

Ear Cuffs

Our ear cuffs are designed to rest comfortably at the center of the earlobe. With a standard 4mm opening and average inner dimensions of 10x8mm, they are crafted to fit most ear sizes. However, individual fit may vary depending on ear shape and size.
