Jewelry Size Guide

Use our jewelry size guide to find your best fit before placing an order. Here you can learn how to measure your ring size, understand necklace lengths, and choose jewelry that feels comfortable for everyday wear.

Ring Size Guide

Our ring sizes are listed according to US sizing. To find your best fit, you can measure a ring you already own or measure around your finger with a soft measuring tape, string, or paper strip.

For the most accurate result, measure your finger at the end of the day when your hands are naturally warm. Avoid measuring when your fingers are very cold, as this can make the size feel smaller than usual.

Method 1: Measure a Ring You Already Own

Choose a ring that fits the finger you want to wear the new ring on. Measure the inner diameter of the ring in millimeters, then compare it with the size chart.

Method 2: Measure Your Finger Circumference

Wrap a non-elastic string or paper strip around your finger. Mark where the ends meet, then measure the length in millimeters. Compare the measurement with the ring size chart.

Method 3: Visit a Local Jewelry Store

For the most accurate size, you can visit a local jewelry store and ask for professional ring sizing help.

NOTE: If you are between two sizes, we usually recommend choosing the larger size for a more comfortable fit.

Necklace Size Guide

Necklace length can look different depending on your height, neck size, body shape, and how you style your outfit. The chart below is for reference only, but it can help you choose the length that best matches your preferred look.

Bracelet Size Guide

To measure your bracelet size, wrap a soft measuring tape around your wrist where you would normally wear a bracelet. If you prefer a snug fit, add about 0.5 inch / 1 cm to your wrist measurement. If you prefer a looser fit, add about 1 inch / 2–2.5 cm.

Please check each product page for specific bracelet length or adjustability details before ordering.
