Three easy ways to measure at home

Pick whichever is easiest with what you have lying around. If you can, try two methods and compare, it is the surest way to land on the right number.

Method 1

Measure a ring you already own

This is the most reliable way, especially if you are buying a surprise gift.

You will need: a ring that already fits, plus a ruler with millimeters

Take a ring that fits the finger you have in mind. Lay it flat.
Measure straight across the inside, from one inner edge to the other. That distance in millimeters is your inside diameter.
Type that number into the Quick size finder above, or find it in the chart.

💡Tip. A digital caliper gives the cleanest reading, but a clear plastic ruler held over the ring works just fine.

Method 2

Wrap your finger with string

No ring handy? All you need is a bit of string or paper.

You will need: string, thread, or a thin strip of paper, plus a ruler

Wrap the string snugly around the base of your finger, where the ring will actually sit.
Mark the spot where the end meets the rest of the string.
Lay it flat against your ruler and measure the length in millimeters. That is your circumference.
Drop that number into the Quick size finder above and switch the menu to "mm around."

💡Tip. Snug, not tight. Pulling the string too hard gives you a size that will feel pinchy by mid-afternoon.

Complete US ring size chart

Every size from 3 to 13, in quarter steps, the way we craft them. Match your measurement to the row, or search for a number.

US Size	Diameter (mm)	Circumference (mm)

Diameter is the distance straight across the inside of the band. Circumference is the length all the way around. Both are measured on the inside of the ring.

Tips for the perfect fit

A few small things make a real difference between a ring you notice all day and one you forget you are wearing.

Measure at the end of the day

Fingers swell a little as the hours pass. An evening measurement gives you a fit that stays comfortable from morning to night.

Check the right hand

Your dominant hand usually runs a touch larger. Measure the exact finger on the exact hand the ring is meant for.

Mind a wide band

Wider bands, around 3mm and up, sit tighter than thin ones. If your ring has a wide band, go up by a quarter to half a size.

Watch the weather

Cold shrinks your fingers, heat swells them. Measure at room temperature for the truest read.

When you are between sizes, size up

A slightly loose ring is an easy fix. A ring that will not pass the knuckle is a harder one. If you are torn between two sizes, take the larger.

💍If your size lands wrong, we make it right. Free resizing in your first 7 days, you just cover return shipping. See our Resizing Policy for the details.

Still not sure? We do this every day.

Send us your measurement and we will confirm your size before you order. A two minute chat usually settles it.

FAQs

Yes, lab grown diamonds are entirely real. They share the exact same physical, chemical, and optical properties as natural diamonds. The only difference is their origin; they are created in a controlled environment using advanced technology rather than being mined from the earth.

Because they are genuine diamonds, lab grown stones score a perfect 10 on the Mohs hardness scale. This makes them incredibly resilient against scratches and chips, offering the exact same lifelong durability as natural diamonds.

Yes. Because they have the same carbon structure as mined stones, lab grown diamonds will pass traditional diamond tester tools. Only highly specialized laboratory equipment can distinguish the growth patterns between a lab-created and an earth-mined stone.

No, a lab grown diamond will never cloud, fade, or lose its brilliance. Just like a mined diamond, its sparkle is permanent. Routine cleaning is all that is needed to remove everyday oils and keep the stone looking pristine.
