Custom Designs With Client Jennifer Zimring

Jennifer Zimring and I connect over more than gems and precious metals. We’re both raising kids in the Bay Area, have backgrounds in medicine, and care deeply about the origins, quality, and ethics of our jewelry. Yet we were brought together by a particularly beautiful loose garnet.

How to Choose High Quality Emeralds
Posted on
Humanity has been captivated by the emerald’s rare and beguiling shades of green - a magical, almost indescribable experience that has been a subject of poetry throughout the ages, going back to the ancient Roman time of Pliny the Elder.
Why We Use Recycled and Fairmined Gold
Posted on
A single gold ring generates 20 tons of mine waste on average. This proves just how powerful our choices can be as jewelry collectors. And it’s just one reason why Thesis Gems & Jewelry strives to make ethically and sustainably mined gold easy for anyone to trace and own.
Let jewelry symbolize something powerful for you- and wear it every day
We wish you a year of love- not only for others but also for yourself. Express gratitude for what you've learned. We invite you to celebrate your failures as opportunities for growth, and to honor your understanding. Choose jewelry for yourself this year.
