Rebecca & Kin
Made for each other. Made for you.
Rinn began with our own engagement ring. We wanted a lab-grown diamond ring & decided to design it ourselves. Then our friends asked us to help them design theirs.. and Rinn was born.
Our story
The Same Stone
A Different Origin
Lab-grown diamonds are chemically, optically and physically identical to those formed in the earth. What differs is how they came to be here — grown under known conditions, traceable to their source, chosen without ambiguity. We select each one ourselves.

Transparent. Always.
Made slowly. Priced plainly.
Almost everything we make is made to order — 18k solid gold or platinum, the stone chosen with you, set by hand. A ring only really works when it's made for the hand it's going on. So we price each piece individually, and show you the stone, the metal and the work before anything is made. Bridal commissions begin at SGD 5,000 for an engagement ring and two bands.

Every purchase does more.
Rinn supports Mei's Own.
Mei's Own is a social enterprise working to bridge the education gap in underserved communities in the Philippines — providing laptops and school materials to children in need. A Rinn piece marks a moment of love in your life, and quietly creates opportunity in someone else's.
