RING SIZE, RE-SIZING & MEASURING TIPS

Finger sizes fluctuate based on factors such as body temperature, time of day, and climate. In warmer conditions and as the day unfolds, fingers have a tendency to swell, while in colder temperatures or during the early morning, they may experience constriction.

Finger sizes tend to fluctuate according to body temperature, time of day, climate etc. Fingers tend to swell up in the heat and as the day progresses, and can constrict when you are cold or early in the morning.

Re-Sizing

Lauren B offers a one-time complimentary ring resizing on all engagement rings within the first year of purchase. For those located in the Tri-State Area we recommend bringing your fiance into the showroom so we can accurately measure their finger size before the resize process. For individuals who are unavailable to be sized in person at our New York showroom, Lauren B will provide you with an insured reverse shipping label via email. Round trip shipping fees are dependent on the value of your ring. Completion of the Reverse Shipping Authorization form is required and must be enclosed with the contents of your shipment. Please ensure an accurate measurement prior to sending the ring for re-fitting so we can have the ring sized properly.

Frequently Asked Questions

How does ring sizing work?

Visit our New York City showroom for ring sizing before designing your perfect ring. An on-site diamond consultant will measure you or your partner’s left-hand ring finger for the most accurate fit. For surprise proposals, take one of your partner’s rings (worn on the left-hand ring finger) to a jeweler for exact measurements, or ask loved ones for guidance.
Stopping by might be difficult for clients outside of the Tri-State area. In this case, we recommend contacting our Client Services at [email protected] for a free plastic ring sizer. If you are trying to keep the proposal a surprise, take your partner’s left hand (ring finger if possible) ring to be sized. For online measuring, refer to our international ring size chart for help.

What are some ring measuring tips?

Water retention and heat cause fingers to swell, while cold temperatures do the opposite. Fingers also constrict in the morning and swell as the day continues. For an accurate measurement, measure the ring finger at the end of the day. Measuring in the morning means the ring might be too tight as the finger swells later on.
The ring should glide over the knuckle easily and fit snug, yet comfortably, on the finger. Remember, the thinner the band, the tighter the fit should be. Watch our ring-sizing video for assistance online or request a try-at-home plastic ring sizer tray to be mailed to your home. When you’re ready, view our video for helpful instructions.

What does the resizing process entail?

Enjoy a one-time complimentary ring resizing on your engagement ring purchase within the first year of purchase. Email your design consultant to start the process. Ideally, your partner should visit our showroom for an in-person measurement, otherwise, please obtain the accurate measurement before shipping the ring to us. Round trip shipping fees are dependent on the value of your ring. We will email you a prepaid FedEx reverse shipping label, insured for the ring value. You must complete the emailed Reverse Shipping Authorization form and include it with the package. You will receive an alteration ticket when we have the ring. Keep in mind that it takes 5 to 7 business days for ring resizing services.

What is the ring resizing policy?

Going to another jeweler for ring resizing (or any alteration) voids your warranty. Clients who provide sizing confirmation remotely might incur additional re-sizing fees if the alteration is at least one size different, in either direction, smaller or larger, from the original measurement.
Design and specific discrepancies determine the related charges. We cannot alter, exchange, or refund eternity bands. Additionally, we are not liable for fit variations when ring size is provided remotely. We do not recommend resizing more than once. Doing so weakens the band and alters the setting, which could loosen the diamond(s) to the point that it/they fall(s) out.

Can you resize eternity bands?

No, we do not alter or resize eternity bands once they are finished and shipped out. Eternity bands are treated as custom orders and thus do not qualify for return or exchange. If you like the appearance of an eternity band but are not 100% of finger size, we recommend a three-quarter band as these can be resized.

What should I do if I’m between sizes?

If you find that you are between two sizes, opt for the larger size. For one, if you ever get hot or swollen, you won’t have to worry about your ring being too tight. Additionally, having a ring that is too tight can not only be uncomfortable but dangerous as it can get stuck! Besides, there are much easier ways to make a large ring fit more snugly than having to resize a ring that is too small.

Are men’s and women’s ring sizes measured using the same scale?

Yes! If you come into our Manhattan Showroom, we have different sets of sizers for men and women, but if you are a remote client, both men and women can use the try-at-home plastic ring sizer tray for an accurate measurement!

Does band thickness affect ring size?

Yes, the more coverage the band has of your finger, the tighter it will fit. Additionally, stacking rings may also affect the size of the ring you will need; if the ring is not going to sit at the base of your finger, you may need a larger size.
