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.

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

The silver hasn't dulled at all. Size 7 was perfect for me!

Delighted with it.

beautiful and fast delivery.

I do like it, to be clear. I had pictured something with more presence. This is partly on me, but hand photos would help.

Thanks Willow. Scale is hard to judge online and our photos arent helping enough. Were adding real-hand shots so the next person can see it properly.

The 18k white gold is a gorgeous color. She cried. Comments every single week.

Sits so nicely. To be fair, incredible value. The 14k yellow gold hasn't worn at all.

3.1 CARAT IS THE PERFECT SIZE. AMAZING VALUE. EVERYBODY ASKS WHERE IT'S FROM.

I can't believe the price. The 14k rose gold is a lovely color.

The packaging was beautiful. 3.1 ct wears bigger than it sounds. 🥰

The radiant is lovely. Excellent. Wasnt sure about moissy, now converted. Half a star off for the wait.

FAQs

Yes. Moissanite is a gemstone with its own chemical composition and optical properties. The moissanite used in our jewelry is lab-created. It can be chosen as a diamond alternative, but it is not a natural or lab-grown diamond.

Moissanite has different production costs and market pricing from diamond. This can make it a more affordable option, although the final ring price still depends on its metal, stones and setting. A lower price alone does not establish the quality of a ring.

Compare length and width in millimeters alongside photographs on a hand. Carat weight and diamond-equivalent weight are different measurements, so confirm how a product’s size is described. Two stones with similar weight can have different visible dimensions.

Returns are limited to qualifying damaged or incorrectly supplied items, and change-of-mind returns are not accepted. Custom-made and resized pieces have additional restrictions. Contact us within seven days of delivery and check our return and exchange policy for eligibility and shipping responsibilities.

Surface buildup from soap, lotions and everyday wear can make a stone appear dull. Gentle cleaning with warm water and mild soap can help restore its sparkle. Follow the care instructions for the complete ring, including its metal and setting.

No, moissanite is a completely separate and distinct gemstone. While it closely resembles the look of a diamond and is a highly popular alternative, it possesses its own unique physical and optical properties.

Yes, moissanite actually has a higher refractive index than a traditional diamond. This means it bends light differently, resulting in exceptional brilliance and a slightly more colorful "fire" or sparkle when exposed to light.

Absolutely. Moissanite is one of the hardest gemstones available, scoring a 9.25 on the Mohs scale. It is highly resistant to scratching, making it exceptionally well-suited for rings worn on a daily basis.

Moissanite offers incredible value and is significantly more affordable than a comparable diamond. This accessible price point allows you to choose a much larger or higher-quality stone while comfortably staying within your budget.
