We're changing the way you shop for engagement rings-forever.

Our Story

Stienhardt & Stones started in 2022 when our founders realized the Lab-grown diamond market wasn’t offering GIA-graded, high-color, and high-clarity diamonds for a reasonable price. Typically, diamonds change hands between dealers and middlemen before landing at the end consumer, which results in higher prices. Utilizing our history as a natural diamond manufacturer, we seized the growing popularity of lab-grown diamonds to pivot from wholesaling natural diamonds out of our overseas office to creating a retail-facing, direct-to-consumer storefront based out of New York City. Combining our 60 years of diamond-cutting experience, more efficient supply chain, and vapid approach to social media marketing, we are able to pass on savings to the end consumer while providing a long-lasting product that can be passed down for generations to come.

Our Purpose

Two years ago, our founders, a dedicated family working side by side at a small table in Manhattan, embarked on a remarkable journey. Today, Stienhardt & Stones is proud to be the fastest-growing engagement ring company in the nation. Our passion for diamonds and exceptional design drives us to deliver superior products and experiences at every turn.

At the heart of Stienhardt & Stones are technology and compassion, essential to our mission of enhancing life's significant moments. We proudly craft every ring using lab-created diamonds and ethically sourced materials, ensuring affordability without compromising quality. Our meticulous process, based entirely in New York, guarantees that each piece meets our exacting standards before it leaves our hands.
