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

About this ring

An Asscher cut lab-grown diamond rises in a four-prong crown above a dramatic twisted split shank. Two rows of micro-pave diamonds sweep apart at the center and cross beneath, framing the step-cut stone with brilliant sparkle and bold modern architecture.

Good to know

Questions, answered

Everything worth knowing before you choose your ring. 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?

Every center stone is graded independently by IGI, GIA or HRD, and the certificate ships with your ring.

How do I know my ring size?

Choose your US size above, in quarter steps from 1 to 16. If you are unsure, call or message us before you order and our team will help you get it right.

How long will my ring take?

Each ring is made to your specification and ships within 3 to 4 business days. Insured delivery then takes 4 to 5 business days in the US and 5 to 9 internationally. If you need it sooner, call us and we will do our best.

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.

Can I have it engraved?

Yes, at no charge. Up to 15 characters inside the band. Add it in the engraving field above. Engraved rings can still be returned within 30 days, subject to a 10% restocking fee.

Do lab-grown diamonds hold their value?

They are valued as jewelry rather than as an investment, the same as most fine jewelry. What you gain is size and quality: because we grow our own stones, your budget buys a considerably larger, higher-graded diamond.

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.
