About Oxford Jewelers


Oxford Jewelers, formerly known as Julius Oksenhorn, has been selling fine diamonds and jewelry since 1930. This fourth-generation family business was founded in Newark, moving to Millburn in the late 1960’s. In 2017, the Oksenhorn family decided to retire, entrusting their store and their stellar reputation to their beloved, lifetime employees.

We will continue to uphold the Oksenhorn family’s legacy of honesty and integrity, while continuing to specialize in providing the finest quality diamonds at the fairest prices. This is what keeps clients coming back generation after generation.

Our business has stood the test of time, providing a full range of jewelry services. Our on-premise master jewelers create custom designs and re-style our clients’ precious treasures. We do all types of jewelry and watch repairs, and we especially love to buy your estate jewelry and silver.

At Oxford, you can be assured that the most treasured clients, as well as our newest customers, will always be well taken care of.
