To treat yourself

Rings are an elegant, sophisticated fashion accessory, and many people simply wear them because they love them. A beautiful ring in your chain jewelry collection lets you express your personal style. And if you love wearing several rings together, check out the stackable ring trend.

As a gift

Jewelry makes a wonderful gift. Gold rings are often a romantic gift for birthdays, milestones, engagements or weddings. Giving a chain ring to someone you love is an original gift for any occasion.

For the meaning

Silver rings can symbolize many things, such as belonging to a group, success or reaching a goal. They are also closely linked to ceremonies such as weddings and other cultural traditions.

As an investment

Some gold rings and diamond rings can be seen as investments, as solid gold and fine diamonds can hold or gain value over time.

How to Measure Your Ring Size at Home

There are several ways to measure your finger to find your ring size. Here are the two most common methods.

Method 1: With a string or a measuring tape

1. Wrap a soft measuring tape, a strip of paper or a piece of string around the base of the finger where you will wear the ring. It should be snug but not tight.
2. Mark where the end overlaps, then measure the length in millimeters: this is your finger circumference.
3. Use the ring size chart below to find your US ring size.

Method 2: With a ring you already own

1. Choose a ring that fits the right finger well and slides on and off easily.
2. Measure its inside diameter (edge to edge, across the middle) with a ruler, in millimeters.
3. Use the ring size chart below to find your matching ring size.

Tips to Find Your Perfect Ring Size

1. Measure at different times of day: your fingers can change size with temperature and time of day. The end of the day, when your hands are warm, is ideal.
2. Consider the band width: for a wide band, you may need half a size larger.
3. Think about the knuckle: the ring must slide over it. If your knuckle is larger than the base of your finger, choose a size between the two.
4. Consider your body temperature: fingers are slightly bigger when you are warm and slightly smaller when you are cold.

FAQ: Ring Size

Can my ring size change over time?

Yes. Your ring size can change with age, weight, hormones and other factors, so it's a good idea to measure your finger again from time to time.

What if I'm between two ring sizes?

If you are between two sizes, choose the larger size for a comfortable fit. An adjustable ring is also a great option.

Can a ring be resized?

Yes, many rings can be resized, but it depends on the type of ring and its design. Ask a jeweler whether your ring can be resized.

Knowing your ring size is the key to a comfortable, secure fit. Measure your finger before buying a ring to make sure you choose the right size.
