Years of Fine Jewelry Production Experience
I’m Rebecca Li, and fine jewelry has been part of my life since I was 12, when my parents started their own gemstone and jade business in China.
Over the years, I noticed that people want jewelry to hold their unique story and carry real meaning. But in the U.S., custom fine jewelry can often feel complicated, expensive, and out of reach.
That’s why I created Mesumi with my trusted fine jewelry manufacturing network in China.
By working directly with experienced makers, we can offer more flexibility, thoughtful customization, and much more reasonable pricing.
My goal is to open up this network to people who normally wouldn’t have access to it, so more of us can create jewelry that feels deeply personal and is made to last.
