Size guide
Measure at home in three steps
1. Wrap
A thin strip of paper snug around the base of the finger.
2. Mark
Mark the exact point where the paper overlaps.
3. Measure
Lay it flat on a ruler and read the length in centimetres. That is the “around” column.
Have a ring that already fits? Measure its inside edge to edge. That is the “diameter” column.

Getting it right
- Measure at the end of the day, when fingers are largest
- Go up half a size for a wide band
- It should pass the knuckle with a little resistance
- Measure twice; paper is more reliable than string

By hand in New YorkAbout this band
20 round brilliants ring the band, set so close that neighbouring stones share their prongs rather than each carrying its own four. Fewer claws means less metal across the face and more of the 3.00mm diamonds on show, and the row closes into one continuous circle with no plain back to turn to the palm. Crafted in Silver at 3mm. Comfort-fit interior, finished with the Rareva signature inside the shank.
Shipping & returns
Complimentary insured shipping worldwide on every order, with import duties paid by us. Made to order and shipped within 3 to 4 business days, then 4 to 5 business days to reach you in the US and 5 to 9 internationally. Free 30-day returns on standard pieces. Every band arrives in signature Rareva packaging, ready to gift.
Sizing
Choose your US ring size above. Full eternity bands, where diamonds run the whole way around, cannot be resized, so it is worth confirming your size before ordering one. If you are unsure, our team can help before you order.
The Rareva promise

Good to know
Questions, answered
Everything worth knowing before you choose your band. If something is not covered here, we are a phone call away.
Are your diamonds real diamonds?
Yes. Lab-grown diamonds are chemically, physically and optically identical to mined diamonds. Same carbon, same hardness, same fire. The only difference is origin. We grow ours ourselves, in our own CVD reactors, and have done since 2019.
Is every stone certified?
Our diamonds are graded independently by IGI, GIA or HRD on the 4Cs: cut, color, clarity and carat. You choose your color and clarity grade on the product page.
How do I know my ring size?
Choose your US size on the product page. Full eternity bands, where diamonds run the whole way around, cannot be resized, so it is worth confirming your size before ordering one. If you are unsure, our team can help before you order.
Will it sit flush against my engagement ring?
Straight bands sit flush against a straight-shank ring. If your engagement ring has a low-set center stone or a shaped setting, a contour or chevron band is designed to nest against it without a gap. Send us a photo of your ring and we will tell you which profile fits.
What metals and widths can I choose from?
Every band is made in platinum, sterling silver, and 10K or 14K white, yellow and rose gold. Widths vary by design and are shown on the product page so you can see how the profile sits against an engagement ring.
Will it cloud, fade or scratch over time?
The diamonds will not. They rate 10 on the Mohs scale, exactly like mined diamonds, so they do not cloud, discolor or lose brilliance. The metal picks up fine surface marks with daily wear, as all precious metal does; a professional polish restores it.
What does shipping cost?
Nothing. Shipping is complimentary worldwide on every order, fully insured and tracked, with import duties paid by us. Standard pieces can be returned free within 30 days.
How should I care for it?
Warm water, a drop of mild soap and a soft brush is all it takes. Remove your band for the gym, gardening and swimming to spare the setting.
Can I see it before I buy?
Yes. Visit our showroom at 15 W 47th Street, 10th Floor, New York. Walk in or book an appointment, and we will show you the piece in person.
Still deciding? Our team will walk you through it, with no pressure.
