Luxury you can feel good about

We don't believe in traditional jewelry markups. We've established relationships with the top diamond curators in Boston and New York City, and pass along reasonable pricing to you. You can feel good about your purchase, knowing that we only use top quality stones, platinum and gold, and we're dedicated to giving back to charities that not only propel forward a cure for cancer, but take care of the warriors who battle it every day.

Diamonds that do good

We are a purpose driven brand founded on the belief that buying diamonds and fine jewelry can be a luxurious experience and also a philanthropic one. Our collection features fine jewelry made to last a lifetime, and a percent of all profits are donated to cancer research and patient care.

Doing good is in our DNA. We're passionate gemologists and philanthropists that have dedicated our lives to doing right by people. In 2021 we teamed up to bring together our passions.

We have 45 years of experience in the jewelry business and 20 years of experience working with cancer related charities.

We create and curate timeless essentials, milestone pieces and wedding jewelry. Each piece in our ready to wear collection is named in honor of a cancer warrior we know and love.
