LMJ works closely with our suppliers to offer conflict free diamonds and gemstones in accordance with the Kimberley Process. In addition, we work with several suppliers to source Canadian and other responsibly mined diamonds + sapphires, including our partnership with Misfit Diamonds. We have access to a variety of different provenance and tracing methods, including mine-to-market documentation, CanadaMark diamonds, and statements of origin.

LMJ works exclusively with 100% recycled gold, all of our vendors require yearly recertification with the Responsible Jewelry Council. The RJC defines recycled gold as precious metal that has been previously refined, originating from sources such as old jewelry, industrial scraps, and electronics. We also capture and recycled all of our gold scrap, and offer gold recycling as an option to our local custom clients.

All of our pieces are designed and handcrafted in our Cleveland Heights studio, with care and intention in every detail. To reduce waste and honor the preciousness of our materials, we keep a minimal inventory of finished jewelry and gemstones. Many of our designs are made-to-order, created especially for you.

Every piece is crafted with longevity in mind—made to be cherished, worn often, and loved for years to come. The more a piece stays with you and becomes part of your everyday life, the more sustainable it truly is. Our rings are built with a standard thickness of 1.8mm, ensuring lasting durability.
